2 Quick reference guide

Display The LCD displays preset and parameter information. The default screen is shown after start up

and displays the number and name of the current preset on the lower line of text. When

navigating around the adjustable parameters, other information is shown.

Channel Select Buttons The currently selected input or output channel is shown in the top left corner of the display.

Pressing the channel select buttons scrolls through the available inputs and outputs. If operating

stereo linked the channel pair is shown. For example ‘CH A+B’ means both input A and B

parameters.

Edit Select Buttons The name of the edit parameter page is displayed in the bottom left portion of the LCD.

Pressing the edit select buttons moves through the available parameter pages for the current

input or output.

Parameter Knobs Up to three parameters are shown on the display. The parameter name is shown with its’

current value below. Where appropriate, parameters are grouped according to function. For

example the parametric equalisation page shows centre frequency, width and gain. Turning a

parameter knob clockwise will increase the value of a parameter, turning anti-clockwise will

decrease it. Turning a knob rapidly will cause the action to ‘accelerate’, so the value changes

more rapidly.

Mute Buttons The indicators next to the mute buttons indicate their current status. Pressing a mute button

toggles between the mute on and off.

Store Button The unit has 45 preset locations. To store a preset in a location, press the store button and use

the parameter knobs to select the preset location and name the preset. Pressing the store

button again completes the task. Pressing any button other than store during the process

cancels the procedure.

Recall Button To recall a preset, press the recall button and use parameter knob A to select the required

preset. Pressing the recall button again will activate the preset. You will then be asked to

confirm by pressing recall once more. As with the store function, pressing any button other will

cancel the process.



Limiter Settings In order to offer the maximum of protection, some factory presets of the DMS26 can be entered

with the fixed limiting device with 0 dBu, limiting the power to approximately 30 W in 8 . It is then

essential to set the threshold according to your devices.

To do it :

▪ with the front panel buttons

– Use "CH" button to go to the selected output – Use the "Parameter" button to go to the Threshold parameter – Adjust with the parameter knob.

▪ with dedicated software

- Go to panel control of DP2696 (Device then Add Device Panel, select

DP2696, press enter) - Open selected "Output" window (1 to 6) - Setting Threshold is located at the bottom right and can be adjusted

from - 40 to +20 dBu The following table expresses the threshold corresponding to the nominal output power provided by the amplifier. Values for a standard gain of 26 dB

Level in dBu Power under 8 Ω Power under 4 Ω

0 30W 60W +1 38W 76W +2 48W 96W +3 60W 120W +4 75W 150W +5 95W 190W +6 120W 240W +7 150W 300W +8 190W 380W +9 240W 480W +10 300W 600W +11 380W 760W +12 480W 960W +13 600W 1200W +14 760W 1520W +15 960W 1920W +16 1200W 2400W +17 1520W 3040W +18 1920W 3840W

Limiter threshold : threshold (dBu) = 20 log ( (Power (W) x Impedance ())/0,775) - amplifier gain (dBu). Also see Tecnare Technical paper.

Assignment of the input signals towards output signals ▪ with the front panel buttons

- Use "CH" button to go to the selected output - Use the Parameter button to go to the "source" function. - Choose source with the first knob which offers possibility between the

Inp_A, Inp_B & Sum_A+B



▪ with dedicated software

- Go to panel control of DP2696 (Device then Add Device Panel, select DP2696, press enter)

- Open Crossover window. - Access to the choice of the source is in the first column of the table.

Connection to a computer Connection RS232 Many laptops do not comprise a connection series RS232. It is then advisable to use a converter USB towards RS232. We can provide an optional accessory USB & RS232 interface or you can use a commercial interface. Unfortunately, few converters meet the requirements to perform correctly with the DP2696. The converters must be equipped with chips FTDI or Prolific X (imperative version "X"). The following converters USB - RS 232 were tested and are satisfactory.

▪ Aten UC 232A (Is the one with the most updated drivers) ▪ Easysync US232B ▪ Easysync USB-COM

An 9 pins extension cable should be envisaged, in addition to the converter, because this device cannot be installed directly on the DP2696. Podware software is available on request or can be download on our Web site: www.tecnare.com.

4 The User Guide

This user manual gives a progressively more detailed description of the functions of the TECNARE DP2696 Digital Loudspeaker Controller. A single page quick reference guide is provided for those users who are experienced with this type of equipment and just need to know how to ‘drive’ the front panel.

A detailed explanation of the front and rear panel controls and indicators is contained in the

next section. The final section describes each individual function or feature with annotated images explaining its’ use. Where appropriate, the LCD is shown to further elaborate on the units’ operation.

To complete the manual a reference section is included, describing the technical

performance of the device complete with graphs of filter responses and details of the Factory Presets and their configuration.

4.1 Front panel

The front panel of the DP2696 provides access to all of the powerful features of the Digital Loudspeaker Controller system.

Figure 1: Front panel schema

Input Signal Indicators

A set of three pairs of LEDs indicate signal present, +4dBu and input clip for each channel. The signal present LEDs operate at approximately –40 dBu, giving a useful indication of even relatively low input signal levels. The +4 dBu LEDs are intended to show nominal operating level and can also be useful for setting system gain structure. Clip LEDs warn the user of input overload and operate at +19 dBu.

Preset Store and Recall

These controls provide access to the 45 presets stored within the device. Pressing the

store button allows the user to name a preset and choose which memory location it will be held in. Pressing store button again completes the process. The Recall function operates in a similar way, pressing the recall button allows the user to select which preset they require, pressing the button for a second time, then confirming, recalls the new DSP settings.

Note that presets cannot be stored or recalled when Secure mode is activated.



Channel Select Buttons

The currently selected channel is displayed on the top left hand corner of the LCD.

Pressing the channel buttons scrolls through the available input and output channels and finally through the utility functions and back to the default screen. If operating a stereo linked preset, the channel name will indicate the channel pairing. For example ‘A+B’ means both input A and B parameters. The name of the output will be shown briefly at the top of the display when stepping onto an output. Edit Select Buttons

The currently selected edit parameter page is displayed on the bottom left corner of the

LCD. Pressing the edit select buttons moves through the available parameters for the current input or output.

Text Display

Preset, channel, parameter and status information is shown on the 2 x 24-character text

display. In most screens the currently selected channel is displayed on the upper line and the edit parameter on the lower line. To simplify the display and enhance security, some parameters or parameter pages are omitted when not relevant.

Parameter Knobs

Three velocity sensitive parameter knobs are used to adjust parameters shown on the display. Up to three parameters at a time are displayed on the screen. The parameter name is shown above the parameter value in each of the three screen sections. The parameter knobs have a fixed association with the screen sections; the rightmost parameter knob adjusts the rightmost parameter and so on.

Output Signal / Limiter Indication

Two LEDs are provided for each output channel. These show the signal level relative to the limiter threshold. The yellow LED will light when the signal is 6dB below the threshold and the red warning LED will light when the limiter threshold is reached.

Mute Buttons and Status LEDs

Each output has a mute button and associated mute status LED. Pressing the button toggles the mute on and off. Note that the mute buttons do not function when the Secure mode is activated.



4.2 Rear panel

The rear panel provides connections for two inputs and six outputs. An RS232 connector allows connection to a remote computer running the “Podware” software. Optional PCC|Net cad is available. PCC|Net must be plugged to the computer via USB, and the DP2696 linked to the adapter with RJ45 cables(you can have several daisy-chained processors).

Figure 2: Rear panel schema

Power Inlet

The Tecnare DP2696 unit should be connected to a suitable mains electricity supply using an earthed IEC C14 connection power lead. The processor has a switch mode power supply that is capable of operating with a nominal mains voltage of 85V to 240V, 50/60Hz without re-configuration.

NOTE: The DP2696 must be earthed to a suitable power earth; failure to do so may affect performance and/or operation and will invalidate warranty and could be potentially hazardous. Network Expansion Port

When fitted with a network option, the network connections will be here.

Communications Port Connector

Tecnare DP4896 processor may be controlled entirely from another controller, typically a Personal Computer, running an application that is compliant with the ObCom standard. Connection will normally be made to the controller via this serial port connector. This port is also used for updating the firmware in the unit. Note that the communications port is NOT disabled when the front panel is made secure using the secure button.



Secure Button

A momentary button is fitted behind the rear panel, between the output XLRs and the RS232 port. When activated, this will disable all the front panel controls so they cannot affect the signal path, making the unit secure against tampering. When in secure mode, the indicators still operate normally. Note that the communications port is still active in secure mode.

Audio Output Connectors

The processed outputs are impedance balanced, and wired pin-1 ground, pin-2 hot and pin-3 cold. An unbalanced input may be driven by connecting pin-3 ‘cold’ signal to the ground connection of the unbalanced destination input. Note that output pin-1’s are ground lifted at audio frequencies but connected to ground at RF for good EMC performance. The intention being that the amplifiers the processor is driving should be responsible for the grounding of their input cable shields.

Audio Input Connectors

All audio connections are fully balanced and wired pin-1 ground, pin-2 hot & pin-3 cold. The two inputs have pin-1 connected directly to the chassis and feed the signal processing chains. If an unbalanced source is used, a connection should be made between the pin-3 ‘cold’ signal and the ground connection of the unbalanced source.

5 Operation

Most of the functions and Systems setting in the Tecnare DP2696 are available via front panel interface, navigating with the front panel buttons and knobs and viewed on the display. The same functions are paralleled in the Podware control software. The user can choose to control DP2696 from the front panel or remotely via Podware control software, as they are interactive and communicate bi-directionally.

5.1 Starting up the unit

The unit will energise as soon as power is applied to the IEC inlet; there is no power switch. During the start up process the firmware application model number and version numbers are displayed and the outputs are muted until the unit has completed its internal checks. Once the start-up routines are complete, the unit is ready to pass audio. The DSP signal path will be restored to the same settings as when it was last powered down and the signal is gradually ramped up to its correct level.

5.2 Selecting a Factory Preset The DP4896 processors have a library of Factory Presets designed to suit a range of applications. Factory Presets contain some parameters that are fixed and hidden from view; the remainders of the DSP parameters are available for user manipulation. The number and type of hidden parameters is dependant on the Factory Preset. To recall a Factory Preset for a particular cabinet or system, press Recall and use the left hand parameter knob A to scroll through the available Factory Preset locations (as indicated by a box symbol after the preset number). Once the appropriate preset has been selected press recall again, at which point you will be asked to confirm the action by pressing recall for a third time. This is to guard against accidental recall of presets.



Factory Presets are locked so they cannot be over-written. The user can, however, store an edited version of a Factory Preset in any free preset location. Details of all the Factory Presets including output designations can be found in Appendix A.

5.3 Creating a Crossover

The Factory Presets are mono and stereo. These Base Presets are stored in locations 1 and 2 respectively. They can be used to develop settings for any loudspeaker. These presets are locked but the user can name and store their own edited versions in any free preset location.

5.4 Navigation and Viewing Parameters

In A Freq Width GainEQ1 100Hz 1.4Q 0.0dB

a b c

a b c

Figure 3: Crossover Menu Many of the processing elements in each input and output path have features that may

be controlled by the user, such as gain, frequency or limiter threshold. We call these adjustable features parameters.

A parameter may be adjusted when it is displayed by turning one of the three-parameter knobs. Each of the three-parameter knobs is associated with a zone on the display. Adjusting the leftmost parameter knob will change the value of the parameter showing in the leftmost zone of the display and so on. Turn a knob clockwise to increase the value of a parameter, or anti-clockwise to decrease it. The knobs are velocity-sensitive so turning a knob rapidly will cause the action to ‘accelerate’, so the value changes more rapidly.

5.4.1 Navigation The DSP parameters are organised by channel. The currently selected channel is

shown in the top left hand corner of the display. You can navigate between the channels by pressing the channel buttons. Pressing the channel buttons will scroll through the channels, utilities and back to the default screen. When using a Preset that is stereo linked, the channel selection will reflect this. For example ‘1&4’ indicates outputs 1 and 4. When navigating onto an output channel, the usage of the output, as defined in the Preset, will be shown briefly at the top of the screen.

Pressing the edit navigation buttons gives access to the various pages of parameters

available for each channel. The currently selected page is shown in the bottom left hand corner of the display. This is omitted on some pages where the function is obvious. The screen shows up to three (normally related) parameters for a given part of the processing functions on a given channel.

CHANNEL

EDIT

Figure 4: Module sub-menu EQ

The edit buttons allow you to scroll, in either direction, through the different processing pages for a given Channel. When you go past the last page, you will be returned to the default page. The channel buttons allow you to scroll, in either direction, through the input and output channels, whilst trying to maintain the currently viewed processing block. If the channel you scroll to does not have the currently viewed processing block, the next one will be shown instead. NB. When the unit powers-up, the settings will be the same as those when the unit was last switched off.

5.5 Presets The device contains a total of forty-five user and Factory Presets. The user cannot

overwrite the basic mono or basic stereo Preset programs.

5.5.1 Preset Recall To select an existing preset, press the Recall Button so the indicator above it

illuminates. Turn parameter knob A until the required preset number is shown on the display. Factory Presets are indicated by a box symbol appearing after the preset number. Press the Recall Button again to activate the Preset. Pressing any other button will cancel the operation.

Users can develop their own Preset based on one of the Factory Presets stored within the device. Once a Preset has been recalled, a user has complete freedom to adjust any or all of the parameters. Factory Presets can be used as the basis for user Presets but they have some parameters that are predefined as a function of the loudspeaker system. These parameters are "hidden" from the user, as they should be constant regardless of application.

5.5.2 Preset Store

To store the current Preset in a user location, press the Preset Store Button so the

indicator above it illuminates. Turn the first parameter knob until the required Preset location number is show on the display. A Preset name of up to 12 characters in length can be entered using parameter knobs B and C. Pressing the Store Button again completes the process and stores the Preset. As with Preset Recall, pressing any other button cancels the operation.

The user can overwrite non-protected Presets only; if an attempt is made to save a Preset in a location already occupied by a Factory Preset a ‘LOCKED PRESET’ message is displayed.

6 DSP Processing Layout



6.1 Stereo / Mono Formats

There is only one ‘standard’ layout of the processing blocks, but flexible routing and control linking allows this layout to be adapted to a wide variety of applications. There are two ‘Formats’, Mono or Stereo. With the Mono format, all outputs have unique parameter settings, and all outputs are identical in terms of processing functions and routing capability. This is the most flexible Format.

Stereo format pairs the inputs and outputs for stereo operation, the parameters of each member of the pair being identical. The routing of inputs to outputs is fixed. This format is intended for symmetrical stereo operation, eliminating the need to make identical parameter adjustments for each channel. The channel pairing is: Left and Right Inputs:

Outputs 1 (routed from L input) and 3 (routed from R input)

Knob A: Delay, adjustable in variable steps from 0 to 400ms The delay parameter is adjustable in fine steps at low values; the adjustment becomes

progressively coarser as the value increases. The velocity sensitive Parameter Knobs therefore provide accurate setting of driver offset delays (typically below 10ms) and rapid setting of longer system alignment delays.

Knob A: Frequency, out (off), 20.0Hz to 25.6kHz in variable steps Knob B: high pass filter type

System high pass filtering is provided for the input signal. This is the preferred location

for high pass filtering as it affects all outputs and can therefore improve inter-band phase relationships. Filter type is selectable from Butterworth, Bessel, Linkwitz-Riley and Hardman. Filter slopes of up to 4th order or 24dB / octave are provided. Not all filter types are available in all slopes. For example 18dB / octave Linkwitz-Riley filters do not exist. The Hardman type filter is always described by its’ order as the filter becomes progressively steeper rather than following a linear slope so a dB/octave description is not accurate. Parametric Equalisation Eight sections of equalisation are provided, two shelving filters and six fully variable parametric sections. High and Low shelving filters

Filter type is selectable from Butterworth, Bessel, Linkwitz-Riley and Hardman. Filter slopes of up to 8th order or 48dB / octave are provided. Not all filter types are available in all slopes. For example 18dB / octave Linkwitz-Riley filters do not exist. The Hardman type filter is always described by its’ order as the filter becomes progressively steeper rather than following a linear slope so a dB/octave description is not accurate. Parametric Equalization Eight sections of equalisation are provided in a similar format to the input channel equalisation; two shelving filters and six parametric.

6.4 Utilities

Three utility functions are provided to adjust screen contrast, the display units used for parametric equalisation bandwidth and switch between stereo and mono mode.

The device automatically adjusts for the variations in display contrast as the

temperature of the LCD changes. The screen contrast utility control sets the base contrast of the screen and also allows optimization for a given viewing angle.

Parametric equalisation width parameters can be displayed in either ‘Q’ or bandwidth,

expressed in octaves.

Util Screen ParaEQ1.. 100% BW=Q

a b c

Care should be taken when swapping between mono and stereo mode as the

parameter set for the left hand channels will be copied to the right hand side, overwriting those settings. This is not reversible and could represent quite a significant and potentially damaging change to the processing.
