2.1.1 PSAIR22N ENCLOSuRE HARD POINTS

There are many possible locations and methods to attach the PSAIR22N speaker enclosure to any given aircraft. These include attachment to existing approved mounts attached to structural hard points, mounting to cross tube/support struts, Meeker mounts, etc. drawing 1.1 showing the dimensions of the PSAIR22n enclosure is provided on page 1-11.

To facilitate mounting of the PSAIR22N speaker array, each side of the PSAIR22N enclosure has 8 pre-drilled holes with 8-32 PEM nuts for attachment of bracket support plates. These plates are sold in pairs (PS-SUPRT-n) or as part of the PSAIR22n demo bracket Kit (PSbRKT22n). When attaching the plates with the eight screws provided, hand start the screws to avoid stripping the PEM nuts out of metal inadvertently.

drawing 1.2 for the PS-SUPRT-n Support Plates is provided on page 1-12. Please refer to this drawing when designing and fabricating any custom bracket or mounting apparatus for your aircraft so that the installation will securely attach to the enclosure and/or support plates and target the speaker array in the desired downward position and angle of sound projection.

2.1.2 AMPLIFIER INSTALLATION FOR PSAIR22NS

When installing the PSAIR22NS, the amplifier (PSAMP600 or PSAMP800) is installed separately. The amplifier comes with it’s own enclosure and mounting base plate. It can be mounted anywhere in the aircraft where there is suitable space. The base plate of the PSAMP600 or PSAMP800 includes dual slide latches which lock onto secured bushings.

There are three methods available for securing the bushing for the slide latch as shown in Figure 1.2. (5/32 rivet, #8 screw and nut, #8 round head wood screw.) Choose the appropriate method for the substrate you are attaching the bushing to. (Spacers and fasteners are not provided.) See Drawing 1.5 on page 1-15 for complete amplifier dimensions.

3.1 AuDIO CONTROLLER

The PSAIR22n (or the separate PSAMP600 or PSAMP800 if connected to the PSAIR22nS) can connect to most tactical airborne audio panels and public address (PA) controllers equipped with a suitable “PA” or audio out capability such as the Power Sonix PSRCU, the Technisonic A710, A711, A711L and A790 audio panels, and many Cobham/NAT/AEM PA controllers. Please note that “intercom” or “paging” connections designed for speaking into the cabin or interior of the aircraft are typically not suited for our high-powered speakers. Please consult the Installation manual for your audio/PA controllers for appropriate installation instructions specific to your equipment. If necessary, consult with your Power Sonix agent/dealer or the Power Sonix factory prior to installation for guidance.

3.1.1 PSRCu REMOTE CONTROL uNIT

If using a Power Sonix PSRCU remote control unit, installation and operating instructions for the PSRCU can be found in Power Sonix document PSIM0011. An audio signal connection is made between the “Remote” connector on the PSAIR22n (or on the separate PSAMP600 or PSAMP800 in the case of the PSAIR22nS) and the PSRCU with a “Remote” cable. See Drawing 1.13 for the applicable Remote cable for your configuration. Please note that “XX” denotes cable length in our cable descriptions/part# (10’ standard, other lengths by order).

3.1.2 TECHNISONIC A790 PA AuDIO PANEL

Complete installation instructions for the Technisonic A790 PA controller and other Technisonic audio panels can be found at http://til.ca. The Interconnect drawing for connecting the Technisonic A790 to the “Remote” connector on the PSAIR22n (or on the separate PSAMP600 or PSAMP800 in the case of the PSAIR22nS) is drawing 1.10 on page 1-21.

3.1.2.1 TECHNISONIC A790 CONNECTOR KIT

When ordering the A790 audio panel, the associated installation connector kit PS-Conn-A790is required. This kit consists of the 25-pin DB connector and 25 pins. The interconnect diagram provided in this manual only illustrates how the 6 wires from the PSAMP600 “REMOTE” connector attach to the A790’s 25-pin DB connector. The determination of how to connect the remaining pins on the A790 connector will need to be made by the installer in consultation with the appropriate manuals for the other audio and radio components in the communications system configuration. The A790 draws 700 mA current.

If you desire to purchase the parts for the connector kit directly from a distributor of electronic components, we offer the following resource:

3.1.3 OTHER AuDIO CONTROLLERS

For installation instructions for other Technisonic, Cobham, NAT, Anodyme (AEM), etc. audio panels and/or PA controllers, please consult the manufacturer’s manual.

The Northern Airborne (NAT) or Anodyne Electrical Manufacturing (AEM) AA21 and AA22 series audio controllers can be used with the PSAIR22n. The AA22 series wiring diagram is shown in drawing 1.18 on page 1-28.

noTE: if using the NAT AA21-400 audio controller, it will be necessary to add a 390 ohm, ½ watt resistor across Pins d & E of the Power Sonix “Remote” input to prevent over-driving and distortion. This can be done at the factory internal to the amplifier or installed externally.

For assistance with the Interconnect for the PSAIR22n and such other audio controllers, consult with your authorized Power Sonix representative or the Power Sonix factory.

1-4



3.2 PSAIR22NR WITH EMBEDDED REMOTE CONTROL

The PSAIR22n is available with an integral remote control unit built into the amplifier. This version is called the PSAIR22nR. The “R” signifies the built-in Remote Control board in the speaker enclosure that allows the PA to be controlled from compatible audio control panels, such as the Technisonic A710, A711 and A711L. (Note other modifications may be necessary.)

If using a PSAIR22nS speaker enclosure with a separate amplifier, the built-in Remote Control board is put inside the amplifier enclosure. This changes the model of the amplifier from a PSAMP600 to a PSAMP600R, or a PSAMP800 to a PSAMP800R.

Control of the system is achieved by keying (grounding) one of the 7 pins. See the 7-PIN Remote connector function chart in Figure 1.3 below. Keying (grounding) the desired pin utilizing external switches, turns the unit on/off, activates the microphone input, starts and stops siren or trill, or cuts the output volume to a predetermined low level. To increase this level, turn the internal potentiometer clockwise until the desired output level is achieved. Additionally, there are two connection lines that provide for an external LEd power output level indicator. A 7-pin connector is used for the “REMoTE” connector on the PSAIR22nR (see Pin-out below in Figure 1.3). See the “Remote” cable and mating connector call outs for the PSAIR22nR on drawing 1-13 on page 1-24.

All inputs and outputs are opto-isolated from system power for optimal noise and interference reduction. Some features may need to be keyed by an externally controlled toggle switch mounted in the cockpit.

Custom cables for the PSAIR22NR can be ordered separately. Consult with your Power Sonix representative or with the factory.

4.1 CABLES & INTERCONNECT

In general, every Power Sonix external mount installation will require: 1) a cable to deliver power to the speaker enclosure or separate amplifier, 2) a cable to deliver the audio signal from the audio controller/remote control to the amplified speaker enclosure or separate amplifier.In the case of the PSAIR22NS where the amplifier is installed separately, a third cable is needed: 3) a speaker cable to connect the amplifier to the PSAIR22NS enclosure.

If a PSRCU Remote Control Unit is used as the audio controller, an additional cable to connect the PSRCU to a commercial MP3 player/iPod type device is needed (PSCBL-RDR-1A).

4.1.1 POWER CABLE

The PSAIR22N can be powered from the aircraft power buss, or alternatively from an auxiliary 28VDC battery pack supplied by Power Sonix. Power Sonix can make the cable for you or connector kits are available for you to make your own cables. See Drawing 1-11 for standard power cables to connect to aircraft power, Drawing 1-12 for cables to auxiliary 28VDC batteries.

NOTE: In our cable product names, “XX” denotes the length of the cable in feet and is to be specified for each installation by the installer at the time of ordering the cables from Power Sonix. If not specified, 10’ is our standard length for power and remote (audio) cables.

Standard aircraft power buss cables will have a 2-pin female connector to connect to the 28dVC male connector on the PSAIR22n enclosure (or in the case of the PSAIR22nS, to the PSAMP600/PSAMP800 series amplifier). The other end will have ring terminals to attach to the aircraft’s DC power supply. If using a Power Sonix auxiliary 28 VDC battery pack, the cable will have a 2-pin female connector appropriate for the specific Power Sonix battery being used.

Power Boosted Configuration: If the installation location on your aircraft results in power cable lengths in excess of 15’, we recommend 12 AWG or lower stranded cable. Alternatively, you can add a “power boost” to the PSAIR22N making it a PSAIR22NP. For PSAIR22nS installs, adding the “power boost” to the PSAMP600 turns it into a PSAMP800. This compensates for natural power losses over these longer power cable lengths. Please specify appropriate parts in bold when configuring your solution with this option and requesting quotes.

4.1.1.1 AuXILIARY BATTERY AND CHARGERPower Sonix offers an auxiliary 28VDC sealed lead-acid battery for airborne applications when tying into the aircraft power buss is not an option. This battery, PS-BAT2-28PB, will have one connector on the top, used for delivering power to the amplifier or amplified speaker array, and for connecting the AC Charger, PS-CHGR-28/5. The power cable for the battery is shown in Drawing 1-12. The Charger has a customized cable for quick attachment to the battery pack.

4.1.2 REMOTE CONTROL (AuDIO) CABLE

The PSAIR22N installation requires a cable from the audio controller (PSRCU, Technisonic A790, etc.) to the “REMoTE” connector on the PSAIR22n (or in the case of the PSAIR22nS, on the PSAMP600/PSAMP800 series amplifier). Illustrations of our Standard “Remote” cables, as well as Remote cables for the “Embedded Remote” variants (PSAIR22nR, PSAM600R and PSAMP600R) can be found on drawing 1.13.



4.1.2 COn’t

If using the Technisonic A790 audio controller, remote cable PSCbL-RCU-XXA is used. one end of this cable will be finished with the appropriate REMOTE mating connector for the PSAIR22N or separate PSAMP600/PSAMP800. The other end is OPEN and ready to be finished on site by the installer with the required 25-Pin connector kit PS-CONN-A790 (sold separately) that connects the remote cable to the A790 PA Panel as well as to the aircraft’s audio controller/ICS.

For the A790 25-pin D-connector assembly, please consult the aforementioned Technisonic manuals and the ICd drawing 1.10 on page 1-21.

4.1.3 AMPLIFIER TO SPEAKER CABLE (FOR MODEL PSAIR22NS)

When using a PSAIR22NS with a separate PSAMP600 or PSAMP800 amplifier, a cable is needed to connect from the “SPEAKER” connector on the amplifier to the “SPEAKER” connector on the PSAIR22nS.

See drawing 1.14 for the appropriate speaker cable drawing. drawing 1.3 on page 1-13 shows the location of the speaker connection on the underside of the PSAIR22nS enclosure.

NOTE: In our cable product names, “XX” denotes the length of the cable in feet and is to be specified for each installation by the installer at the time of ordering the cables from Power Sonix. If not specified, 10’ is our standard length for power and remote (audio) cables.

4.1.4 RECORDER/AuXILIARY AuDIO CABLE

The PSRCU Remote Control Unit “REC” input connector enables users to use “commercial off-the-shelf” (CoTS) audio devices to deliver pre-recorded audio content through the remote control and out to the speakers. If this capability is desired, cable PSCBL-RDR-1A should be specified with the PSRCU. See Drawing 1.14 for the drawing of this “RDR” cable.

Audio panels such as the Technisonic A790 have the ability to accept direct input from a COTS devise. For the “standard” A790 audio panel, specify PSCBL-RDR-A790 (Drawing 1.15). If the Technisonic A790 has been “modified” to accept a direct microphone (PSMIC-A790 - see Section 5.1.3 below), the required cable to connect the audio devise is PSCBL-RDR-A790M (drawing 1.16).

For other audio panels, please refer to the user manuals for your COTS audio devise and your audio controller to determine options and requirements.

5.1 MICROPHONE

The microphone used in conjunction with the Power Sonix PA system can be the microphone in the cockpit headsets used by the crew for radio communications, or it can be a separate hand-held microphone provided by Power Sonix (PSMIC). Which method you use will depend upon preference of the flight crew and the audio controller chosen for your installation.

5.1.1 COCKPIT HEADSET MICROPHONES

The microphone used in most tactical cockpit headsets (such as david Clark) can be connected to the PA when a PA audio panel such as the Technisonic A790 PA panel is used. The controls on the A790 will direct the audio signal from the main audio panel/ICS to the PA. The 25-pin connector on the back of the A790 audio panel include the requisite pins for this capability. Please refer to the A790 Installation and Operating manuals for more specific details.

5.1.2 POWER SONIX PSMIC MICROPHONE

The PSMIC microphone is used in conjunction with the PSRCU Remote Control Unit. This a modified Shure 150 ohm noise-canceling dynamic microphone.

5.1.3 POWER SONIX PSMIC-A790 MICROPHONE FOR TECHNISONIC A790

The “standard” A790 audio panel from Technisonic allows a commercial audio player to be plugged into the 3.5 mm “AUX In” jack on face of the unit. However this “standard” configuration does not enable a hand-held microphone to also use this “AUX IN” jack.

In instances where the user wants the ability to plug in a separate hand-held microphone (PSMIC-A790) into the A790 audio panel, a factory modification to the A790 is required and must be specified at the time of ordering the A790 unit. A jumper is installed to provide a microphone bias. Note that the PSMIC-A790 is unique to operating with the “modified” Technisonic A790 audio panel and must also be specified at the time of placing your order.

Figure 1.5 Technisonic A790 Front View

6.1 MAINTENANCE

Routine testing of the loudspeaker equipment should be incorporated into the maintenance or flight-ready checklist. Simple troubleshooting can be conducted in the hanger. Power Sonix Tech Support is always available via phone, Skype and email to assist in the installation and troubleshooting. Any major issues with your equipment would require a Return Merchandise Authorization (RMA) for factory servicing (see Warranty page iii for instructions).



1-9

6.1.1 AMPLIFIER CHECKS

When normal operation of the PSAIR22n is impaired the following possibilities should be checked with respect to the amplifier:

1. Press the “Press To Test” (PTT) light to make sure power is available (if using the Power Sonix Remote Control Unit PSRCU)2. Check the input Polarity of the DC power supply (on the power cable coming into the PSAIR22n or in the case of the PSAIR22nS, to the PSAMP600 or PSAMP800). Make sure sufficient voltage is available, and that excessive voltage is not applied; (Voltage reading should be between 24-32 volts dC) 3. Check all cables for shorts or opens. dC resistance on the speaker drivers should be approximately 1.8 ohms per driver. 4. If using auxiliary 28V battery, check connection/cables. The PTT light does not indicate until pressed.5. If using PSRCU, turn Power Switch off. PTT light does not indicate until pressed.6. Check dC power to cockpit audio controller. If using PSRCU Remote Control Unit, the PTT light will not indicate normally or when pressed if no power is available.7. Make sure the signal source is not shorted or connected to any noise source.8. The Amplifier may require factory maintenance. Note that the amplifier will automatically reset when reapplying power after a fault condition due to a short is experienced.

6.1.2 POWER SuPPLY CHECKS

The power supplied to the PSAIR22N or to the PSAMP600/800 by the aircraft DC power buss or by an auxiliary 28VDC battery should measure between 24 and 32 volts unloaded and l/2 to l volt lower under load. Check for the proper polarity.

6.1.3 LOuDSPEAKER AND CABLE CHECKS

Testing of loudspeakers and cables may, to some extent, be done visually. All connections should be free from dirt, moisture and open or shorted conditions. All receptacle threads should be completely engaged. A continuity meter may be used to establish the state and correctness of wiring. An ohmmeter touched across the loudspeaker inputs should cause an audible click sound.

6.1.4 PRECAuTIONS IN MAINTENANCE

To avoid serious damage to system components while undergoing troubleshooting or testing, please read these warnings carefully before initiating test procedures.

CAUTION: Do not operate the system from an inadequate power supply or a shop supply, giving rise to high voltage transients.

CAUTION: A grounded test probe from an AC powered meter or Scope placed across the output will short the output to ground and trigger the shutdown circuitry. All test equipment should be isolated from ground potential.

6.1.5 AMPLIFIER/SPEAKER MAINTENANCE

The amplifier and speakers should be kept clean and free from exposure to static charge accumulation and debris. There are no serviceable parts inside our Class d amplifiers.



1-10

CAUTION: Tampering with the amplifier board itself will void your warranty.

Speaker Driver Maintenance - No maintenance of the compression speaker driver is required. Should a driver fail while under warranty, please return it to Power Sonix for replacement. If out of warranty, please call Power Sonix to purchase a new driver. We recommend having 2 spare speaker drivers (Part # PS-D4Z) for quick replacement on-site if ever needed.

6.1.6 SPEAKER DRIvER CHECKS & REPLACEMENT

A compression driver may fail due to several causes:

1) The coil or its terminals may short to the mounting and cause the amplifier to cut off. This is apparent (once the leads of the suspected driver are separated from other drivers of the speaker assembly) by a continuity test between the driver leads.2) A voice coil short (not likely) showing zero ohm between voice coil leads will also cause the amplifier to cut off.3) A voice coil open-circuit (more likely) will show with an ohmmeter check between leads. no sound will result when the ohmmeter is applied.4) A noisy driver results when the voice coil rubs against the magnetic pole pieces. Noise can best be localized to a single driver unit by connecting each unit singly and energizing each with the amplifier output.

Check each driver for a short or an “open”. A short is evidenced by less than 1 ohm resistance and an “open” by any resistance over 3 ohm. The correct reading should be approximately 1.8 ohms per driver.

When replacing a faulty driver in your PSAIR22N, temporary disassembly of the re-entrant tip and horn will be necessary to gain access to the y-throat adapter and drivers. Disconnect the leads before unscrewing any driver. Be sure to reconnect the leads to the terminals when re-assembling the speaker assembly. Observe the color code to preserve the speaker polarity:

RED WIRE TO #1 TERMINAL, BLACK WIRE TO #2 TERMINAL

6.1.7 RESETTING PROTECTIvE CIRCuIT The amplifier board inside the PSAIR22n series enclosure, the PSAMP600 and the PSAMP800 amplifier are designed with self-protecting circuitry to interrupt the operation whenever harmful conditions exist which might endanger the amplifier components.

Such a condition might be an excessive load current or an output short. once the protective circuit is activated, the flow of power is stopped in the affected channel and no further operation is possible without corrective action. If the trouble was due to a temporary or transitory cause, operation may be resumed by simply turning the power switch “OFF” on the 3rd party PA audio controller or our PSRCU Remote Control Unit, wait 5 seconds to allow the internal circuitry to reset, then turn back to “on”.

The Power FETs of this system are subject to damage when exposed to excessive heat, voltage, and current for even short periods of time. The design incorporates a protective circuit which disables the amplifier when safe operating currents are exceeded.
