IMPORTANTIn order to comply with current European safety regulations it is essential that the Naim loudspeaker connectors supplied with amplifiers and loudspeakers are used.

Do not under any circumstances allow anyone to modify your Naim equipment without first checking with the factory, your dealer, or your distributor. Unauthorised modifications will invalidate your guarantee.

For your own safety do not under any circumstances open Naim equipment without first disconnecting it from the mains.

Warning: an apparatus with CLASS I construction shall be connected to a mains socket outlet with a protective earthing connection.

Where the mains plug or an appliance coupler is used as the disconnect device, the disconnect device shall remain readily operable. To disconnect the equipment from the mains remove the mains plug from the mains outlet.

The following label is attached to all mains powered equipment:

NOTEThis equipment has been tested and found to comply with the relevant EMC and Safety Standards, and, where applicable, also complies with the limits for a class B digital device, pursuant to Part 15 of the FCC Rules.

These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and the receiver.

• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

• Consult your Naim dealer or an experienced radio/TV technician for help.

2 Audio ConnectionsIt is important for both safety and performance that the standard cables supplied are not modified.

2.1 Interconnect Cables

If options are available with your equipment and installation, DIN interconnect sockets should be used in preference to RCA Phono sockets. One end of each Naim interconnect cable is marked with a band to establish its correct orientation. The band denotes the end that connects to the signal source.

Interconnect plugs and sockets should be kept clean and free from corrosion. The easiest way to clean them is to switch off the equipment, pull the plugs out of their sockets, and push them back in again. Contact cleaners and “enhancers” should not be used as the film they tend to deposit may degrade the sound.

2.2 Loudspeaker Cables

Loudspeaker cables are vitally important and your dealer should make them up to suit your installation. The cables should each be at least 3.5 metres long and of equal length. The recommended maximum is normally 20 metres although longer cables may be viable with some Naim amplifiers. Contact your dealer or Naim Audio for advice.

Many Naim amplifiers are designed only to work with Naim loudspeaker cable and using alternatives may degrade the performance or even damage the amplifier. Naim loudspeaker cable is directional and should be oriented so that the printed arrow points towards the speakers. The amplifier/loudspeaker connectors supplied are designed to make a robust electro-mechanical connection and to comply with European safety regulations. They should be used in preference to alternatives.

3 Mains Power ConnectionWhere fused plugs are used 13 amp fuses should be fitted. Fuses of a lower rating will fail after a period of use. Do not wire voltage dependent resistors or noise suppressors into mains plugs. They degrade the mains supply and the sound.

IntroductionNaim Audio products are conceived with performance as the top priority.

Careful installation will help ensure that their full potential is achieved.

This manual covers all Preamplifiers, the Nait 5i Integrated Amplifier,

all Power Amplifiers and all Power Supplies but begins with general

installation notes and statutory safety warnings for all Naim Audio

products. Product specific information begins in Section 5.

1 Equipment InstallationNormally your Naim Audio equipment will have been installed by the dealer who sold it to you - even if you live outside their immediate vicinity. In any event however your dealer is responsible for making sure that the system sounds as it should. Information given here is not intended to reduce this responsibility in any way.

3.1 Mains Plug Wiring

In some territories a mains plug may need to be fitted to the supplied mains lead. As the colours of the wires in the mains lead may not correspond with the coloured markings identifying the terminals in the plug proceed as follows:

The wire which is coloured GREEN-AND-YELLOW must be connected to the terminal in the plug which is marked by the letter E or by the safety earth symbol or coloured GREEN or GREEN and YELLOW.

The wire which is coloured BLUE must be connected to the terminal in the plug which is marked with the letter N or coloured BLACK.

The wire which is coloured BROWN must be connected to the terminal in the plug which is marked with the letter L or coloured RED.

3.2 Non-rewirable Mains Plugs

If a non-rewirable plug is cut from a mains lead (for whatever purpose) the plug MUST be disposed of in a way to render it totally useless. Considerable shock hazard exists if the cut-off plug is inserted into a mains outlet.

3.3 Mains Circuits and Cables

A hi-fi system usually shares a mains circuit with other household equipment, some of which can cause distortion of the mains waveform. This distortion can lead to mechanical hum from amplifier and power supply transformers. Naim transformers are large in size with heavy gauge windings, making them relatively sensitive to such distortion and it may be necessary to take account of any hum when siting your equipment.

Transformer hum is not transmitted through the speakers and has no effect on the performance of the system; however, a separate mains circuit may reduce it. Such a circuit (ideally with a 30 or 45 Amp rating) will also improve system performance. Advice on the installation of a separate mains circuit should be sought from a qualified electrician.

Do not substitute alternative mains leads and plugs to those supplied. They are selected to offer the best possible performance.

2

4 General InstallationNaim equipment is designed to offer the finest sound quality possible avoiding compromise wherever practical. This can lead to circumstances that may be unfamiliar. The notes that follow contain advice specifically related to Naim equipment as well as more general warnings about the use of domestic audio products. Please read them carefully.

4.1 Siting The Equipment

In order to reduce the risk of hum audible from the loudspeakers, power supplies and power amplifiers should be located a reasonable distance away from other equipment. The maximum separation distance for connected equipment is that allowed by the standard interconnect lead.

Some Naim equipment is extremely heavy. Ensure that your equipment rack or table can support the weight and is stable.

4.2 Switching On

Source components and power supplies should be switched on before the power amplifiers. Always switch amplifiers off and wait a minute before connecting or disconnecting any leads. Always use the power switch on the product rather than a mains outlet switch.

A “thump” may be heard from the loudspeakers as power amplifiers are switched on. This is normal, will not cause any loudspeaker damage and does not point to any fault or problem. A mild “pop” may also be heard shortly after power amplifiers are switched off.

4.3 Running In

Naim equipment takes a considerable time to run in before it performs at its best. The duration varies, but under some conditions the sound may continue to improve for over a month. Better and more consistent performance will be achieved if the system is left switched on for long periods. It is worth remembering however that equipment left connected to the mains can be damaged by lightning.

4.4 Radio Interference

In some circumstances, depending on where you live and the earthing arrangements in your home, you may experience radio frequency interference. Controls on broadcasting in some territories allow very high levels of radio frequency radiation and both the choice and exact siting of equipment may be critical. Susceptibility to radio frequency interference is related to the wide internal bandwidth necessary for high sound quality. Systems incorporating moving coil phono preamplifiers and active crossovers are more likely to suffer. A radio frequency filter kit is available for some Naim equipment but sound quality will be progressively compromised as more elements of the kit are fitted. In situations of extreme radio interference Naim equipment may be unsuitable.

4.5 Non-standard Cables

Use of non-standard speaker cables or interconnects on some products may invalidate your guarantee.

4.6 Lightning Precautions

Your Naim hi-fi system can be damaged by lightning. Power amplifiers are particularly at risk and should be turned off and disconnected from the mains when there is risk of lightning strike. For complete protection all mains plugs and any aerial cables should be disconnected when not in use.

4.7 Liquid Precautions

Equipment must not be exposed to dripping or splashing and no objects filled with liquid, such as vases, should be placed on the equipment.

4.8 Equipment Fuses

Mains powered Naim Audio equipment is fitted with a mains input fuse on the rear panel adjacent to the mains input socket. Replace it if necessary only with the spare fuse supplied or with identical fuses. Repeated failure of this fuse points to an equipment or system fault that should be investigated by your dealer or at the factory by Naim itself.

4.9 Problems?

Consumer protection varies from country to country. In most territories a dealer must be prepared to take back any equipment he has sold if it cannot be made to work satisfactorily. A problem may be due to a fault in the system or its installation so it is essential to make full use of your dealer’s diagnostic skills. Please contact your local distributor, or Naim Audio directly, if any difficulties cannot be resolved.

Some Naim equipment is made in special versions for different territories and this makes it impracticable to arrange international guarantees. Please establish the local guarantee arrangements with your dealer. Contact Naim Audio directly for help and advice if necessary.

4.10 Repairs and Updates

It is essential that repairs and updates are only carried out by an authorised Naim dealer or at the factory by Naim itself. Many components are custom made, tested or matched and appropriate replacements are often unobtainable from other sources.

Direct contact to Naim for service or update information should be made initially through the Service Department:

Tel: +44 (0)1722 332266Email: [email protected]

Please quote the product serial number (found on its rear panel) in all correspondence.

NAC 5525 Installation and OperationThe NAC 552 preamplifier does not incorporate an internal power supply and can be used only in conjunction with the NAC 552PS power supply. Diagram 6.3 illustrates connection of the NAC 552 to its power supply.

The four transit screws on the underside of the NAC 552 case should be removed before use and must be replaced if the unit is to be re-packed and shipped. These transit screws must not be used in any other Naim product. Do not invert the NAC 552 once the transit screws are removed.

5.1 Source Inputs and Record Outputs

The input selector buttons arranged along the upper bank select the source signal to be routed to the power amplifier and the loudspeakers. Below them, in the lower bank, are a corresponding array of buttons which select the signal to be routed to the preamplifier’s record outputs.

These separate source and record sections enable one source (a CD player, for example) to be listened to whilst the output from another (say, the tuner) is simultaneously selected for recording.

Note: It is possible to lock the record controls and prevent accidental de-selection during recording. Record-lock is switched on or off by pressing the source mono button four times within six seconds.

Indicators are fitted to the NAC 552 rear panel above each input socket. These indicators illuminate to provide information on input selection and on input mapping setup and programming.

5.2 Input Socket Mapping (Program Mode)

Any NAC 552 source input socket can be selected by any button. For example, while the NAC 552 default setup is for the CD input button to select input socket No. 2, custom programming of input mapping could enable any input socket to be selected by pressing the CD button. Mapping of each record button follows the corresponding source button.

Input mapping setup is accessed through the NAC 552 program mode. To switch into program mode press and hold the prog key on the remote handset (in preamplifier mode). Program mode is indicated by a flashing indicator on the volume control and the record select indicators extinguishing. If no function is operated within five minutes of entering program mode the NAC 552 will return to normal mode automatically.

Any of the six source buttons on the front panel can be mapped to any of the nine stereo inputs (seven DIN sockets and two RCA Phono socket pairs) on the rear panel. In program mode, as a source input is selected, a rear panel indicator will illuminate to designate the socket to which it is mapped.

To change the input socket mapped to a source button, select the source button and use the front panel record mute and mono buttons to scroll along the input sockets. If the input socket selected is already mapped to a source button the indicator above the socket will flash repeatedly. It is possible to map one input socket to more than one source button but NOT to map multiple input sockets to one source button. The remote handset record mute and mono functions can also be used to set up input mapping.

To exit from program mode press and hold the prog key on the handset until the record select indicators are restored and the volume indicator stops flashing.

5.4 Automatic Input Switching

The NAC 552 incorporates an optional automatic input switching feature which can select the appropriate input as soon as any handset function for a particular Naim source component is operated. For example, if the tuner input is selected on the NAC 552 and the CD play key is operated on the handset, the NAC 552 will automatically switch to the CD input. Automatic input switching can be programmed to operate independently on any combination of the CD, AV and Tuner input buttons (and sockets to which they are mapped).

To enable automatic input switching, first switch the NAC 552 into program mode as described in Paragraph 5.2. The front panel source mono button will illuminate if automatic switching is already enabled. If it is not enabled it can be switched on by pressing the source mono button twice.

With auto switching enabled, pressing the source mono button will reveal the inputs selected for auto switching by their button indicators illuminating for a short time. Repeated operation of the source mono button will sequentially select through each possible combination of CD, Tuner, AV inputs, and auto switching disabled (CD, Tuner and AV button indicators off). When the desired inputs selected for auto switching are indicated, stop pressing the source mono button.

NAC 552The remote handset mono (Flash) or mon (Narcom 3) key can also be used to set up automatic source switching. Automatic input switching only becomes operational on exiting from program mode by pressing and holding the handset prog key.

Note: In a few cases some further equipment configuration may be required for auto switching to operate correctly on the AV input. Please contact your retailer or local distributor for advice.

5.5 AV Integration (Unity Gain)

The NAC 552 unity gain function enables an audio-visual processor to be integrated such that its volume control takes over command of signals connected to selected NAC 552 inputs. Unity gain can be selected on input sockets 4 and 5 only (the corresponding input buttons will depend on the input mapping set up).

To select unity gain, first switch the NAC 552 into program mode as described in Paragraph 5.2. The front panel source mute button will illuminate if unity gain is selected on any input. If it is not enabled it can be switched on by pressing the source mute button twice.

With unity gain enabled, pressing the source mute button again will reveal the inputs selected by their button indicators illuminating for a short time. Repeated operation of the source mute button will sequentially select each combination of Input 4, Input 5 and unity gain disabled. When the desired inputs are indicated, stop pressing the source mute button. The selected inputs will then be enabled for unity gain. The remote handset mute key can also be used to set up unity gain.

Unity gain only becomes operational on exiting from program mode by pressing and holding the handset prog key.

Note: The unity gain feature must be used with care. It effectively by-passes the NAC 552 volume and balance controls leaving any signal connected to a unity gain input to be passed to the power amplifier and speakers at full volume. In order to reduce the potential for inadvertent mishap, any subsequent modifications to input mapping will automatically disable previously set up unity gain inputs. Additionally, if an input is selected which has unity gain enabled, the NAC 552 volume and balance handset functions will be disabled and their indicators will turn off. This will be flagged by the volume or balance indicators flashing if either handset function is operated.

5.6 Handset Volume and Balance Control

The remote handset volume and balance keys provide some alternative control characteristics. A quick press and release of a key will adjust by a preset “nudge”. A quick press and release of a key followed by press and hold will cause continual slow adjustment. Simple press and hold will cause continual fast adjustment.

5.7 Mute and Mono

Mute and mono functions can be controlled independently for source and record signals via the front panel buttons to the left of the two banks of source and record selection buttons. Mute silences the output signal, while mono sums the left and right channels.

5.8 Display

The NAC 552 front panel button display can be switched off by pressing the remote handset (in preamplifier mode) disp function. Any subsequent handset or front panel operation will temporarily restore the display. A second operation of the disp function will permanently restore the display.

5.9 Switch-on

After switch-on, via the NAC 552PS front panel power button, the NAC 552 will remain muted for 30 seconds while control systems and circuits stabilise. The source side will then un-mute automatically leaving the record side muted (and its circuits unpowered).

5.10 Remote Control

The Flash remote handset supplied with the NAC 552 duplicates all configuration and control functions. See Section 23 for more information. The NARCOM and iCom handsets will also control the NAC 552. See Sections 24 and 25 for more information.

5.11 Defaults

To restore all programmable settings to the factory defaults press and hold the remote handset disp key while the preamplifier is in program mode. The preamplifier will exit from program mode following this operation.

NAC 252




Note: It is possible to lock the record controls and prevent accidental de-selection during recording. Record-lock is switched on or off by pressing the source mono button four times within six seconds.


The NAC 252 has six DIN input sockets and two alternative pairs of RCA Phono sockets. The RCA Phono sockets can be mapped individually to the CD and AUX 2 input buttons in place of the DIN sockets.


Once in program mode press and hold the remote handset 1 key to select or de-select the RCA Phono socket input for CD, and the remote handset 6 key to select or de-select the RCA Phono socket input for AUX 2. The corresponding front panel input buttons can similarly be used to select or de-select the RCA Phono socket inputs. The appropriate input button indicator will flash three times on selection of the RCA Phono option and once on selection of the DIN option.



The NAC 252 incorporates an optional automatic input switching feature which can select the appropriate input as soon as any handset function for a particular Naim source component is operated. For example, if the tuner input is selected on the NAC 252 and the CD play key is operated on the handset, the NAC 252 will automatically switch to the CD input. Automatic input switching can be programmed to operate independently on any combination of the CD, AV and Tuner input buttons.


With auto switching enabled, pressing the source mono button will reveal the inputs selected for auto switching by their button indicators illuminating for a short time. Repeated operation of the source mono button will sequentially select each combination of CD, Tuner, AV inputs, and auto switching disabled (CD, Tuner and AV button indicators off). When the desired inputs selected for auto switching are indicated, stop pressing the source mono button.

The remote handset mono (Flash) or mon (Narcom) key can also be used to set up automatic source switching. Automatic input switching only becomes operational on exiting from program mode by pressing and holding the handset prog key.



The NAC 252 unity gain function enables an audio-visual processor to be integrated such that its volume control takes over command of signals connected to selected NAC 252 inputs. Unity gain can be selected on the AV input only.

To select unity gain, first switch the NAC 252 into program mode as described in Paragraph 8.2. The front panel source mute button will illuminate if unity gain is selected. If it is not enabled it can be switched on by pressing the source mute button twice. Deselect unity gain by again pressing the source mute button twice. Unity gain only becomes operational on exiting from program mode by pressing and holding the handset prog key.

Note: The unity gain feature must be used with care. It effectively by-passes the NAC 252 volume and balance controls leaving any signal connected to a unity gain input to be passed to the power amplifier and speakers at full volume. Additionally, if the AV input is selected while unity gain is enabled the volume and balance handset functions will be disabled and their indicators will turn off. This will be flagged by the volume or balance indicators flashing if either handset function is operated.

NAC 112x


The input selector buttons select the source input signal to be routed to the power amplifier and the loudspeakers.

The NAC 112x has six DIN input sockets and two alternative pairs of RCA Phono sockets. The RCA Phono sockets can be mapped individually to the CD and AUX 2 input buttons in place of the DIN sockets.

Input mapping setup is accessed through the NAC 112x program mode. To switch into program mode press and hold the prog key on the remote handset (in preamplifier mode). Program mode is indicated by a flashing indicator on the volume control. If no function is operated within five minutes of entering program mode the NAC 112x will return to normal mode automatically.

Once in program mode press and hold the remote handset 1 button to select or de-select the RCA Phono socket input for CD, and the remote handset 6 button to select or de-select the RCA Phono socket input for AUX 2. The corresponding front panel input buttons can similarly be used to select or de-select the RCA Phono socket inputs. The appropriate input button indicator will flash three times on selection of the RCA Phono option and once on selection of the DIN option.

To exit from program mode press and hold the prog key on the remote until the volume indicator stops flashing.


The NAC 112x incorporates an optional automatic input switching feature which can select the appropriate input when any handset function for a particular Naim source component is operated. For example, if the tuner input is selected on the NAC 112x and the cd play key is operated on the handset, the NAC 112x will automatically switch to the cd input. Automatic input switching can operate on any combination of the cd, tuner and av inputs.

To enable automatic input switching, first switch the NAC 112x into program mode as described in Paragraph 17.1. Program mode is indicated by a flashing indicator on the volume control.

The front panel mon button will illuminate if automatic input switching is already enabled. If it is not enabled it can be activated by pressing the handset mon key or front panel mon button twice.

With automatic input switching enabled, pressing the mon key or the mon button will reveal the inputs selected for automatic input switching by their button indicators illuminating for a short time. Repeated operation of the mon key or mon button will sequentially select through each possible combination of cd, tuner, and av inputs, and automatic input switching disabled (cd, tuner and av indicators off). When the desired inputs selected for automatic input switching are indicated, stop pressing the key or button.

To disable automatic input switching, press the mon key or mon button repeatedly until no input buttons are illuminated. Automatic input switching only becomes operational or is cancelled on exiting from program mode by pressing and holding the handset prog key.

17.3 Input Volume Compensation

The NAC 112x incorporates an input volume compensation system that enables different source component output levels to be matched.

To program the volume compensation for each input first set the volume control to a comfortable listening level with the loudest source (probably CD). Switch the NAC 112x into program mode as described in Paragraph 17.1. Now select an input to be adjusted in comparison to the previously selected source and use the handset vol up and vol down keys to set an appropriate volume level. The preamplifier volume control will not rotate during this operation. Select a further input to adjust if required.

Note: The front panel volume control cannot be used to adjust input volume compensation. The handset volume keys only must be used.

To exit program mode press and hold the handset prog key until the volume control indicator stops flashing.

Note: Input Volume Compensation can be reset by restoring the factory defaults. See Section 17.11


The unity gain function enables an audio-visual processor to be integrated such that its volume control takes over command of signals connected to selected NAC 112x inputs. Unity gain can be selected on the AV input only.

To select unity gain, first switch the NAC 112x into program mode as described in Paragraph 17.1. The front panel mute button will illuminate if unity gain is selected. If it is not enabled it can be switched on by pressing the remote handset mute button. Deselect unity gain by again pressing the handset mute button.

Note: The unity gain feature must be used with care. It effectively by-passes the NAC 112x volume and balance controls leaving any signal connected to a unity gain input to be passed to the power amplifier and speakers at full volume. Additionally, if the handset preamplifier volume or balance functions are operated while the unity gain AV input is selected, subsequently selected inputs will be modified by the new volume or balance settings.

17.5 Handset Volume

The remote handset vol keys provides some alternative control characteristics. A quick press and release of a key will adjust the volume by a small amount while a press and hold will cause first slow and then faster adjustment.

17 Installation and OperationThe NAC 112x preamplifier does not incorporate an internal power supply but must be used in conjunction with either a Naim power amplifier incorporating a preamplifier power output, or with an appropriate Naim power supply. Diagram 18.3 illustrates the NAC 112x connected to a Flatcap 2 power supply.

NAIT 5i20 Installation and OperationThe NAIT 5i Integrated Amplifier should be installed on a dedicated equipment stand intended for the purpose. Care should be taken to ensure that it is level. The NAIT 5i can be operated from its internal power supply only. No power supply upgrade is possible.

20.1 Inputs

The front panel input selector buttons select the source input signal to be routed to the power amplifier and the loudspeakers. The four buttons are labelled cd, tuner, tape and av. Each input button corresponds to a pair of rear panel RCA Phono input sockets. The cd and tuner inputs are additionally provided with alternative DIN sockets. These should be used in preference to the RCA Phono sockets if practical. Do not connect both the DIN and RCA Phono sockets of one input simultaneously.

20.2 Automatic Input Switching (Program Mode)

The NAIT 5i incorporates an optional automatic input switching feature which can select the appropriate input as soon as any handset function for a particular Naim source component is operated. For example, if the tuner input is selected on the NAIT 5i and the cdplay key is operated on the handset, the NAIT 5i will automatically switch to the cd input. Automatic input switching can be set up to operate on any combination of the cd, tuner and av inputs.

To enable automatic input switching, first switch the NAIT 5i into program mode by pressing and holding either the prog key on the remote handset (handset in preamplifier mode) or the cd button on the amplifier front panel. Program Mode is indicated by a flashing indicator on the front panel volume control. If no function is operated within five minutes of entering program mode the NAIT 5i will return to normal mode automatically.

The front panel tape button will illuminate if automatic input switching is already enabled. If it is not enabled it can be activated by pressing the handset 3 key or front panel tape button twice.

With automatic input switching enabled, pressing the 3 key or the tape button will reveal the inputs selected for automatic input switching by their button indicators illuminating for a short time. Repeated operation of the 3 key or tape button will sequentially select through each possible combination of cd, tuner, and av inputs, and automatic input switching disabled (cd, tuner and av indicators off). When the desired inputs selected for automatic input switching are indicated, stop pressing the key or button.

To disable automatic input switching, press the 3 key or tape button repeatedly until no other buttons are illuminated. Automatic input switching only becomes operational or is cancelled on exiting from program mode by pressing and holding the handset prog key or front panel cd button.


The Unity Gain function enables an audio-visual processor to be integrated with the NAIT 5i such that its volume control takes over command of signals connected the amplifier’s AV input.

To select unity gain, first switch the NAIT 5i into program mode as described in Paragraph 20.2. The AV input button will illuminate if unity gain is already enabled. If it is not enabled it can be activated by pressing the handset 4 key or the front panel AV button. Deselect unity gain by again pressing the 4 key or the AV button. Unity gain only becomes operational or is cancelled on exiting from program mode by pressing and holding the handset prog key or front panel cd button.

Note: The unity gain feature must be used with care. It effectively by-passes the NAIT 5i volume control leaving any signal connected to the unity gain input to be passed to the power amplifier and speakers at full volume. Additionally, if an input is selected which has unity gain enabled, the volume handset functions will be disabled and their indicators will turn off. This will be flagged by the volume indicator flashing if its handset keys are used.

20.4 Restoring Defaults

The programmable functions can be restored to their default, (inactive) states by pressing and holding the front panel tuner button or the handset disp key (handset in preamplifier mode) while the NAIT 5i is in program mode.

20.5 Outputs

A stereo set of speaker connection sockets are provided on the rear panel. The sockets can accept standard 4mm plugs, but to comply with European legislation the Naim connectors supplied should be used. Naim Audio speaker cable will provide the best results, however, a wide range of speaker cable types can be used without risk of damage to the amplifier.

Ensure when connecting speakers that they are “in-phase”. That is, the positive and negative connection orientation at both the speaker and amplifier ends of the cable is the same for both speakers.

The tape output always carries the selected input signal. No “record monitor” function is available.

20.6 Volume and Mute Control

The remote handset vol keys provides some alternative control characteristics. A quick key press and release will adjust the volume incrementally. A quick key press and release followed by press and hold will provide continual slow adjustment. Simple press and hold will provide continual fast adjustment.

Mute control is available from the remote handset only. Mute is indicated by the amplifier volume control indicator flashing.

Note: The NAIT 5i does not incorporate any facility for channel balance adjustment.

NAIT 5i20.7 Display

The NAIT 5i front panel button display can be switched off by pressing the remote handset (in preamplifier mode) disp function. Any subsequent handset or front panel operation will temporarily restore the display. A second operation of the disp function will permanently restore the display.

20.8 Remote Handset

The iCom remote handset supplied with the NAIT 5i provides remote access to the front panel input selection and volume control functions of the amplifier as well as providing a mute facility and enabling access to the program mode required for setting up the Automatic Input Switching and Unity Gain

functions. See Section 25 for more information. The Flash and NARCOM 3 handsets will also control the NAIT 5i. See Sections 23 and 24 for more information.

20.9 Connections Notes

The negative input and output connections for each channel are common. The mains earth (ground) should always be connected regardless of what other equipment is used in conjunction with the amplifier. This only grounds the case and the electrostatic screen within the transformer, and is not connected to the signal negative. In order to avoid hum loops, the signal negative of the whole system should be connected to the mains earth (ground) in one place. This should be the primary signal source.

Flash Handset23.1 IntroductionFlash is factory pre-programmed to operate any Naim preamplifier or cd player, the NAT 05 tuner and AV2 audio-visual processor. Additional Naim sources may be catered for in the future. Contact your dealer or local representative for information.

Flash is supplied without batteries fitted. To fit the batteries, remove the battery cover with the supplied hexagon driver and slide the batteries into the handset body taking care with their orientation. Replace the battery cover. Do not over-tighten the fixing screw. With batteries fitted the handset is ready for use. Flash is designed to switch off if unused after 10 seconds. It switches on immediately if it is moved or a key is pressed.

23.2 Using Flash

Flash can be set to control each equipment type through the four preset keys beneath the display. The selected equipment mode is indicated in the display above each preset key. When a preset key is pressed the display and the eight master keys and the numeric keys will re-configure appropriately. The display for each equipment type shows a representation of the eight master keys and their functions.

The AV preset key will also wake an av processor from standby. Press and hold the AV preset key to return the processor to standby mode.

The volume up and down and mute keys are always available to control the appropriate (audio-visual or preamplifier) volume and mute functions regardless of the selected source equipment mode.

The Preamplifier, CD, and AV equipment modes have multiple display “pages” (only one page is necessary for Tuners). The first display page of each provides control of the most commonly used functions, with subsequent pages generally providing access to those less often used. Selection of second and third pages within each mode is made by pressing the appropriate preset key. The currently selected page is shown in the top right corner of the display. Details of the master key functions within each page is described in the following paragraphs:

23.3 CD Track Programming

In CD mode the prog key (display Page Two) enables specific CD tracks and their play order to be programmed.

To program a play order select a track number from the numeric keypad followed by the prog key until the desired selection is complete. During selection, the track number indicated in the display will be followed by either P or —. P indicates that the track is selected, — indicates that the track can be selected.

The prog key can also be used to delete tracks from a play order. To delete a track, press and hold the prog key until the prog indicator in the CD display illuminates then delete the track or tracks using the numeric keypad followed each time by a further operation of the prog key. During deletion the track number indicated in the display will be followed by either C or — or no display. C indicates that the track is deleted, — indicates that the track can be deleted while no display indicates that this is the only track remaining and therefore cannot be deleted.

A random play order can be programmed (from stop with no play order already in place) by pressing prog followed by 1. Similarly, to program a reverse play order, press prog followed by 2.

Play orders can be reviewed by pressing prog while the player is either stopped or playing. The player display will then scroll through the selected tracks. The prog indicator on the player display will illuminate when a play order has been programmed. To clear the program memory press and hold the stop key.

NAP 500


The negative input and output connections for each channel are common. The mains earth (ground) should always be connected regardless of what other equipment is used in conjunction with Naim power amplifiers. This only grounds the case and the electrostatic screen within the transformer, and is not connected to the signal negative. In order to avoid hum loops, the signal negative of the whole system should be connected to the mains earth (ground) in one place. This should be the primary signal source.

Note: Each channel of the NAP 500 is a “bridged” amplifier, so none of the speaker outlet sockets (+ or -) is at earth potential. Avoid connecting mains powered equipment such as electrostatic speakers, sub-woofers and headphone energisers that do not have a floating earth. No plug which is connected directly or indirectly to earth potential should be attached to any speaker outlet (+ or -).

26.2 Protection Notes

In the NAP 500 the fan speed is increased in response to an increase in amplifier dissipation. If the amplifier reaches 70°C due to prolonged running at high level or to airflow being blocked, the output will be interrupted and the fan will run at full speed until it has cooled down. This may take a few minutes.

It is not necessary to switch the amplifier off, but it may be advisable to mute the preamplifier or turn the volume down to avoid surprises when it comes back on.

OPERATION OF THE AMPLIFIER’S THERMAL PROTECTION SUGGESTS PROLONGED USE AT TOO HIGH A VOLUME LEVEL. YOUR LOUDSPEAKERS MAY BE AT RISK IF THIS IS THE CASE. THE VOLUME SHOULD BE REDUCED.

26.3 Loudspeaker Cable and Connectors

Only Naim Audio speaker cable should be used to connect a loudspeaker to the output of the NAP 500. Custom Naim Audio loudspeaker connectors are supplied to make the connection. IN ORDER TO COMPLY WITH CURRENT EUROPEAN SAFETY REGULATIONS IT IS ESSENTIAL THAT THESE ARE USED.

DAMAGE TO THE AMPLIFIER MAY RESULT IF “HIGH DEFINITION” CABLE OR ANY OTHER SPECIAL CABLE IS USED TO CONNECT THE LOUDSPEAKERS.

26 Installation and OperationThe NAP 500 and NAP 500PS should be installed in their final operating locations before connecting cables or switching on. Switch on the source and preamplifier components, with the volume turned down, before switching on the NAP 500. The NAP 500 power button is located on the front panel of the NAP 500PS Power Supply.

Care should be taken when siting the NAP 500 to ensure that the top and bottom ventilation grids are not blocked e.g. by carpet if the unit is to be placed on the floor.

The NAP 500 is very heavy and care should be taken when lifting or moving it. Make sure that the surface it is to be placed on can support the full weight.

NAP 6-50

Unused zone input sockets should be fitted with the supplied yellow shorting plugs. Failure to use the shorting plugs may reduce the reliability with which the NAP 6-50 drops into standby mode. Serious damage is likely to occur if yellow shorting plugs are used on Naim equipment other than the nap 6-50.

The negative input and output connections within each zone are common but there is no signal negative connection between them. The mains earth grounds only the case and the electrostatic screen within the transformer and is not connected to the signal negative. The mains earth must always be connected to “ground” regardless of any other equipment used. In order to avoid hum-loops the signal negative of the whole system should be connected to the mains earth in one place. This should be the primary signal source.

47.1 Operation

Once installed the NAP 6-50 is intended to remain permanently powered-up via its front panel switch. When not in use the amplifier will drop into “standby” mode during which less than 1 Watt is dissipated. Standby mode is indicated by the front panel logo illuminating red. Switch from standby to operational mode

47 Installation and ConnectionThe NAP 6-50 is a six channel power amplifier intended for use in multi-room audio systems. The six channels are configured as three sets of two (left and right). The three sets are intended to provide audio power to drive one pair of loudspeakers in three multi-room “zones”. Audio line level input for each zone is via 4-pin DIN sockets.

The NAPV 175 is heavy and care should be taken when lifting or moving it. Make sure that the surface it is to be placed on can support the full weight.

takes place automatically when a programme signal is detected at any input or, alternatively, can be controlled via the 3.5mm “jack” trigger input socket on the rear panel.

47.2 Protection

The NAP 6-50 uses a fan to assist heat dissipation. Fan speed is increased automatically in response to an increase in heat dissipation. If the internal heatsink reaches 70°C due to prolonged running at very high dissipation, blocked airflow, or fan failure, the mains supply will be interrupted and the indicator light will go off until the amplifier has cooled down. This may take up to thirty minutes.

47.3 Siting

Care should be taken when siting the NAP 6-50 to ensure that the ventilation and fan apertures are not obstructed.

47.4 Loudspeaker connectors

Special Naim Audio loudspeaker connectors are supplied to make the connection to the power amplifier(s). IN ORDER TO COMPLY WITH CURRENT EUROPEAN SAFETY REGULATIONS IT IS ESSENTIAL THAT THESE ARE USED.
