Section I GENERAL INFORMATION

1.1 INTRODUCTION

The PMA7000 with CD option represents the next step in cockpit audio control and intercommunications

utility. Using proprietary IntelliVox® design, this unit eliminates the requirements for intercom squelch

adjustments. The unit is designed for outstanding ergonomics and visually defined mode annunciation and
selection. By providing control for a remote compact disc (CD) player, the system simplifies installation
and operation of entertainment sources for the cockpit and crew.

Before installing and/or using this product, please read this manual completely. This will ensure that you
will take full advantage of all the advanced features in the PMA7000CD and PCD7100-R Remote Player.

1.2 SCOPE

This manual provides detailed installation and operation instructions for the PS Engineering PMA7000­series of Audio Selector Panel/Intercom Systems. This includes the following units:

Description Part Number

Model
PMA7000S-CD MP3 Stereo Audio Selector Panel w Disc controls 7000S-CD
PMA7000MS CD MP3 Stereo Audio Panel as above with Marker 7000MS-CD
Option 1 added to any 7000CD Intercom Recorder System (IRS) Opt 1

Option 3 added to any system Black bezel (no silver trim) Opt 3

Where the functions are identical to all units, it will be referred to herein as a PMA7000CD. Otherwise, the
applicable units will be specified.

1.3 EQUIPMENT DESCRIPTION

The PMA7000-series is a state of the art audio isolation amplifier and audio selector that contains an auto­matic voice activated (VOX) intercom system. It can switch up to three transceivers (Com 1, Com 2 and
Com 3) and six receivers (Nav 1, Nav 2, ADF, DME, MKR and AUX).

A duplex COM 3 mode (selectable at installation) allows the PMA7000 to act as an audio interface be­tween aircraft headphone and microphones and specific aircraft approved

(FAA/FCC) cellular telephone

equipment.

Warning

: Use of non-aviation approved cellular telephone equipment may be prohibited by regulation.

PS Engineering is not responsible for unauthorized airborne use of cellular telephones.

For airborne use, the PMA7000CD must be interfaced with an approved system.

There are two unswitched inputs, for autopilot disconnect, and/or radar altimeter warning. Push buttons
select the receiver audio source provided to the headphones. A SPR button allows the user to listen to the
receiver(s) selected on the cabin speaker. Except for the unswitched inputs, all speaker audio is muted dur­ing transmit.

Push button switches selects one of the communication transceivers for the pilot and copilot position, and
allows radio transmission. In "Split Mode" the PMA7000CD has the ability to allow the pilot and copilot to
operate different transceivers independently. The Com 3/TEL mode (selected at installation) allows the
pilot to use the audio panel for duplex operation, such as with aviation-specific cellular telephones. Exter­nal switches permit telephone operation for the copilot and passengers.

A fail-safe mode connects the pilot headphone and microphone to COM 1 if power is removed for any
reason, or if the power switch is placed in the Off (Fail-safe) position.

PS Engineering

A six-station voice activated (VOX) intercom is included in the PMA7000CD. This system has PS Engi-

neering’s exclusive IntelliVox® circuitry that eliminates manual adjustments. The system contains six sepa-

rate VOX mic circuits, and only opens the microphone channel in use.

The intercom system incorporates pilot isolate and crew modes, two stereo music inputs with "Soft Mute,"
and flashing LED indicators for transmit indications. Intercom control is through front panel-mounted
knob and 3 position mode switch. A concentric volume controls the music level, and intercom level for the
pilot and copilot. Passenger headphone volume is factory set, and adjusted in flight with headset-mounted
volume controls. Passenger volume control is further adjustable through screwdriver access in the top of
the unit. Intercom squelch is automatic.

approved packaging.

2.3 Equipment Installation Procedures

2.3.1 Cooling Requirements

Forced air-cooling of the PMA7000CD or remote player is not required. However the units should be kept
away from heat producing sources (i.e. defrost or heater ducts, dropping resistors, heat producing avionics)
without adequate cooling air provided.

2.3.2 Mounting Requirements

The PMA7000CD must be rigidly mounted to the instrument panel of the aircraft structure and within view
and reach of the pilot position(s). Installation must comply with FAA Advisory Circular AC 43.13-2A. The
unit may be mounted in any area where adequate clearance for the unit and associated wiring bundle exist.

The PCD7100-R Remote CD Player may be located in any convenient location for access to the disc slot.
However, it should be mounted to keep the interconnecting bundle within approximately six feet (2 me-

ters). The unit must be installed within ±30° of horizontal along the pitch axis, and ±10° of horizontal along
the roll axis in level flight.

Avoid installing the units close to high current devices or systems with high-voltage pulse type outputs,
such as DME or transponders. Avoid running the interconnecting bundles near any high current wires.

2.5 Cable Harness Wiring

Referring to the appropriate Appendix, assemble a wiring harness as required for the installation. All wires
must be MIL-SPEC in accordance with current regulations. Two- and three-conductor shielded wire must
be used where indicated, and be MIL-C-27500 or equivalent specification. Proper stripping, shielding and
soldering technique must be used at all times. It is imperative that correct wire be used.

The 6-conductor cable for the remote CD is available from PS Engineering as part number 800-022-0609.

Refer to FAA Advisory Circular 43.13-2A for more information. Failure to use correct techniques may
result in improper operation, electrical noise or unit failure. Damage caused by improper installation will
void the PS Engineering warranty.

NOTE: PS Engineering can make a custom wiring harness for the intercom and CD player portion. Call 1­800-ICS-AERO or see www.ps-engineering.com

2.5.1 Noise

Due to the variety and the high power of radio equipment often found in today's general aviation aircraft,
there is a potential for both radiated and conducted noise interference.

The PMA7000CD power supply is specifically designed to reduce conducted electrical noise on the aircraft
power bus by at least 50dB. Although this is a large amount of attenuation, it may not eliminate all noise,
particularly if the amplitude of noise is very high. There must be at least 13.8 VDC present at the bottom
connector, pin 20, of the PMA7000CD for the power supply to work in its designed regulation. Otherwise,
it cannot adequately attenuate power line noise. Shielding can reduce or prevent radiated noise (i.e., bea­con, electric gyros, switching power supplies, etc.) However, installation combinations can occur where
interference is possible. The PMA7000CD was designed in a RFI hardened chassis and has internal Elec­tromagnetic Interference (EMI) filters on all inputs and outputs.

Ground loop noise occurs when there are two or more ground paths for the same signal (i.e., airframe and
ground return wire). Large cyclic loads such as strobes, inverters, etc., can inject noise signals onto the

for details.

airframe that are detected by the audio system. Follow the wiring diagram very carefully to help ensure a
minimum of ground loop potential. Use only Mil Spec shielded wires (MIL-C-275000, or better).Under no
circumstances combine a microphone and headphone wiring into the same shielded bundle. Always use a
2- or 3-conductor, shield wire as shown on the installation wiring diagram.

Radiated signals can be a factor when low level microphone signals are "bundled" with current carrying
power wires. Keep these cables physically separated. It is very important that you use insulated washers to

isolate the ground return path from the airframe to all headphone and microphone jacks.

Adding a high-performance audio control system, particularly in conjunction with high-performance active
noise canceling headsets, cannot improve on older avionics that were designed for cabin-speaker use. PS
Engineering makes no claim that the audio panel will provide a noise-free audio quality under all installa­tion conditions, particularly with older avionics.

2.5.2 Existing KMA-24 Installation

If the installation replaces a KMA-24 (series -01, -02 or -03), the existing 44 pin connector can be used for
the bottom connector of the PMA7000CD tray as is, providing it is properly installed and wired. No other
changes are required except for external marker lights (see Section 3.7.2 for details). The "key" in the ex­isting connector must be located between pins 7 and 8. This connector will be used in the bottom connector
position. (See Appendix for complete wiring harness details.)

The existing ground bus may be reused for radio shield connections, if it was constructed so it can be relo­cated to the PMA7000CD tray.

2.5.3 Existing PMA6000 installations

In 28-Volt aircraft, the dropping resistor may be removed, however, the 2 Amp breaker should be changed
to 3 Amp. If the old unit is stereo (PMA6000S or PMA6000MS), no rewiring is necessary except to add
additional features.

2.5.3.1 Stereo PMA7000CD installations into monaural PMA6000, PMA6000M.

Installations replacing PMA6000 or PMA6000M require re-wiring of the top connector to accommodate
the stereo configuration. See appendixes for detailed interconnect information.

2.5.4 Power

The PMA7000CD-Series are compatible with both 14 and 28 Volt DC systems. A two (2) Amp circuit
breaker is required for 14 VDC installations, and a three (3) Amp breaker for 28 VDC aircraft. Power and
ground wires must be a twisted

#18 AWG pair. Connect airframe power ground to J1 (bottom connector)

Pin Z only. No dropping resistors are required.

2.5.5 Communications Push-to-Talk

An important part of the installation is the PTT (Push-To-Talk) switches that allow the use of your aircraft
communications radio for transmissions. There are three typical configurations that can be used. Select the
case that best fits the installation. Only the person who presses their PTT switch will be heard over the ra­dio. If the pilot and copilot both use the PTT, the only pilot position has access to the radio. The pilot posi­tion will have PTT control regardless of the mic selector switch or copilot PTT when the PMA7000CD is

OFF/EMG mode.

in the

CASE I: PTT is built into both pilot and copilot yokes.
CASE II: PTT is in pilot yoke only. This configuration requires a modified external PTT switch plugged

into the copilot's microphone jack. (See Appendix A). When the copilot's PTT is pressed, the intercom
switches the microphone audio from pilot to copilot mic.

CASE III: No built in PTT. This requires two built in PTTs to be installed, or modified external PTT

switches to be used. Modify external PTT as required. See Appendix A.

2.5.6 Audio Panel interface

The PMA7000CD is designed to interface with standard aircraft avionics, and presents a 500Ω receiver
impedance. For best results, a twisted-shielded cable is recommended from the avionics audio source to the
audio panel, with the shield grounded at the audio panel end.

Some avionics do not provide a separate audio low, and may introduce additional electrical noise into the
system. For best results, connect the audio low from the audio panel to the radio ground, using one conduc­tor of the twisted-shielded cable.

2.5.6.1 Speaker Load

The PMA7000-series contains a speaker amplifier. Some units with internal speaker amplifiers, such as
the King Radio KX170-series, require a resistive load to prevent damage if their speaker amplifier is not
used. Connect the speaker output from the unit to the load input on the PMA7000CD (J1, pins 19 and L, 16
and M. The speaker load in 16 Ω, 3W.

2.5.7 Com 3 Duplex (TEL) and Cell phone Function

As installed in the standard configuration, the PMA7000CD Com 3 function operates conventionally.
Pushing the Com 3 Xmt button places the receive audio from Com 3 in the headset and applies the pilot or
copilot microphone to the Com 3 when the appropriate PTT is activated.

The COM 3 input is designed to be used for a third aviation transceiver, but is capable of interfacing to a

cellular telephone, including AirCell. Note: Not all cells phone are compatible. PS Engineering, Inc is

does not guarantee function or operation of cell phone inputs or outputs.

The COM 3 duplex mode can be enabled when J2, Pin J is connected to aircraft ground (either directly or
through a switch). In this mode, the COM 3 input and output is compatible with many cellular telephones
utilizing the hands-free headset interface. A 1/8" (using an adapter) or 3/32" jack can be installed on the
aircraft panel, which is interfaced with the PMA7000B as shown below. To connect the cellular telephone
to the jack wired in to COM 3, a patch cord is required. This patch cord is available from PS Engineering
under P/N 425-006-7026 (3/32" to 3/32"). A 1/8" to 3/32" adapter is available from Radio Shack P/N 274-

373.

action, which may include a $10,000 fine per incident. PS Engineering, Inc. does not endorse using

unapproved cellular telephone equipment in flight, and takes no responsibility for the user’s action.

2.5.8 Transmit Interlock

Some communications transceivers use a transmit-interlock system. To fully utilize the Split Mode feature,
this function must be disabled. Consult that manufacturer's installation manual.

2.5.9 "Swap" Mode

When a momentary, normally open, push-button switch is connected between pin 10 on the top connector
and aircraft ground, the user can switch between Com 1 and 2 by depressing this switch without having to
turn the mic selector switch. This yoke-mounted switch eliminates the need to remove your hands from the
yoke to change transceivers. The transfer of TX indication from Com 1 to Com 2 shows that the swap has
been initiated, there is no dedicated swap indicator.

2.5.10 Backlighting

The PMA7000CD has an automatic dimming of the pushbutton annunciator LEDs and marker lamps con­trolled by a photocell. Control of the unit backlighting is through the aircraft avionics dimmer. Connect the
dimmer control line to J1 pin D for 14-volt systems, and to J1 pin F for 28-volt systems. Pin E is light
ground.

If an external dimmer control is not used, a constant low-level back light illumination can be established

for nighttime viewing. Pin D or F (depending on system voltage) must be tied to power (J1, pin 20) for the
back lighting system to work. The photocell mounted in the unit face will automatically adjust the intensity
of the push-button annunciator LEDs.

2.5.11 Unswitched inputs

Bottom Connector, J1, pin T, pin 17, pin U and pin X are the unswitched inputs. These inputs are presented
to the pilot and copilot regardless of the audio configuration, and will always mute the entertainment in­puts. These 510Ω inputs can be used for altimeter DH audio, GPS waypoint audio, autopilot disconnect
tones, air-to-ground (Flitefone) telephone ringer or any other critical audio signal. This input is not related
to the cellular telephone interface.

2.5.12 PA Mute (J1, Pin 18)

Pin 18 of J1 is a TTL logic output that is pulled low during PTT operation. This serves as an input to exter­nal public address system to prevent feedback during transmissions.

2.5.13 Public Address Function (J2, Pin 18)

By connecting the top connector (J2), Pin 18 to ground, the pilot’s microphone audio is placed on the cabin
speaker output. When the pilot’s PTT is activated, his voice is heard over the speaker. The copilot can con­tinue to use the selected com.

We recommend installing a toggle switch to connect the cabin speaker output (pin W, bottom connector) to
a rear or public address speaker instead of the cockpit speaker close to the pilot. This will prevent feed­back.

2.5.14 Control Output (J2, Pin A)

Pin A of the top connector is pulled to ground whenever the AUX button is activated (LED on). This
serves as a control line for external devices, such as a entertainment system that the pilot wishes to control.

This could be used in conjunction with a PA to control J2, Pin 18, as well as an external relay to change to
the cabin speaker from the cockpit.

This pin can also be used to control passenger Karaoke Mode, by connecting to pin V of the J2, or as a
copilot hook switch Pin L of J2, or passenger hook switch pin M, J2.

2.5.15 Intercom wiring

The top connector (J2) is for the intercom, CD interface and additional functions. See Appendix for inter­com connection configurations. It is critical to the proper operation of this system to have this connector
wiring made in accordance with these diagrams. Use 2- and 3-conductor, MIL-spec cable as shown. Con­nect the shields at the audio panel end only, and tie to the audio low inputs as shown.

NOTE: The top connector harness can be custom made by PS Engineering, Inc. Simply call the factory

and obtain a wire harness work-sheet. The harness will be made to your specifications and fully function­ally tested. All hardware is included.

2.5.16 Remote CD wiring

The remote CD Player is powered from the avionics bus through a 2 A PULL TYPE Breaker.

The PCD7100-R is interfaced to the PMA7000CD through a 6-conductor data cable and a 3conductor au­dio cable. These cables must conform to the MIL-C-27500.

2.5.16.1 Entertainment Input

The remote compact disc player is designed to interface with the audio panel as input number 1 J2 pins 15
(left channel) and 16 (right channel), WRT pin T, and is provided to the pilot and copilot. Entertainment
number 2 is provided to the passengers at all times.

In order to use the remote player to provide music to the passengers, it must be interfaced to Entertainment
2 input pins 13 (right), 14 (left), WRT pin R. We recommend installing a DPDT switch to allow isolation
of the music sources if desired. In addition, a volume control for the passengers’ music level is recom­mended. PS Engineering kit Part Number 250-790-0020 is available. See wiring instructions, top connector
for more details.

NOTE: Use the low level

output of any additional entertainment device to connect to

the audio panel. Maximum signal level is 2 VAC p-p.
DO NOT use a speaker-level output, this will cause internal damage in the audio

panel.

2.5.16.1.1 Entertainment muting

The PMA7000CD-system incorporates a "Soft Mute" system. This will mute the entertainment devices
during ICS or radio conversation.

Any signal appearing in the unswitched audio inputs will always mute the entertainment sources, even
though the passengers may not hear the audio tone itself.

Caution: Local oscillators and internal signals from entertainment equipment other than the PCD7100-R

can cause undesired interference with other aircraft systems. Before takeoff, operate the entertainment de­vices to determine if there is any adverse effect within the aircraft systems. If any unusual operation is
noted in flight, immediately switch off the entertainment devices.

All additional entertainment devices must be switched off for both takeoff and landing.

2.5.16.1.2 Entertainment 2 Mute (Pin V)

The ICS button on the PMA7000CD controls the muting (“Karaoke mode”) of entertainment source #1.

Connecting J2 pin V to ground through a SPST switch places the entertainment #2 music source into the
Karaoke Mode. In this mode, incoming music and intercom conversation will not mute the music for the
passengers’ intercom net. This allows uninterrupted music during casual conversation and at times when
radio communications are of lesser importance. See section 2.5.14 for alternative connection.

2.5.17 PMA7000CD Intercom expansion (J2, Pins P, S, and C)

The PMA7000CD contains a 6-place intercom. In applications where more intercom positions are needed,
PS Engineering can provide intercom expansion units, such as the IntelliPAX, part number 11606,
11606R, etc. These can add up to six additional stereo intercom stations, plus independent music input.
Interface to the expansion unit is through J2, pins P (audio input from expansion unit), S (audio output to
expansion unit) and C (9 VDC expansion power).

2.5.18 Playback button Installation (J2, Pin 19- Options 1, ONLY)

To activate the Recording System playback, a momentary push button switch is required. This switch can
be located anywhere in cockpit convenient to the pilot's reach. The switch must be connected to pin 19 of
J2 of the PMA7000CD, and ground

2.6 Marker Beacon Installation

The marker beacon receiver is an option included in the PMA7000MS CD. Non-marker (PMA7000S) units
can provide audio interface with the external receiver (see section 2.5.4).

2.6.1 Marker Antenna Installation

A marker beacon antenna, appropriate to the type and speed of the aircraft, is required (not included). Re­fer to aircraft and antenna manufacturer's installation instructions, as well as AC43.13-2A (or later revi­sion), Chapter 3, for information on proper antenna installation techniques. The marker beacon antenna
must be mounted on the bottom of the aircraft.

2.6.2 External Marker Lights (7000MS-CD)

For installations that require external marker beacon lights, three outputs are available to drive 12-Volt
lamps only. The external output lamps are driven high (typically +9 VDC ±1.5 VDC unloaded, at MAX
brightness) when active. Maximum source current per lamp is 125 mA. Voltage varies with photocell dim­ming.

2.6.3 Middle Marker Sense (7000MS-CD)

A Middle Marker Sense output signal is available from the 7000CD to flight control systems. This function
will not operate during the test mode. This output will go to +4.5 VDC (± 1.0 VDC) when a valid Middle
Marker signal is received. This output is J1, pin 2.

2.6.4 Marker Audio Input (7000S-CD)

If using an external marker receiver, the audio input is J1, pin 21 (MKR input).

2.7 Adjustments

The PMA7000CD is factory adjusted to accommodate the typical requirements for most aircraft configura­tions. There are five adjustments however, that will allow the installer to tailor the specific functions.

2.8 Communications Antenna Installation Notes

For best results while in Split Mode, it is recommended that the one VHF communications antenna is lo­cated on top

of the aircraft while the other communications antenna is installed on the bottom. Any antenna
relocation must be accomplished in accordance with AC 43.13-2A, aircraft manufacturers’ recommenda­tions and FAA-approved technical data.

Warning:

It is probable that radio interference will occur in the split mode when the frequencies of the two air-

craft radios are adjacent, and/or the antennas are physically close together. PS Engineering makes no

expressed or implied warranties regarding the suitability of the PMA7000CD in Split Mode.

2.8.1 Hook Switches

While the mic selector button acts as the hook switch for the pilot, additional hook switches must be in­stalled to have full access to the cellphone system. The copilot hook switch is a SPST switch that connects
pin L of J2 on the PMA7000CD to ground to place the copilot mic audio on the Com 3 audio in duplex
mode for cell phone operation.

PMA7000CD J2, pin M is the passenger hook switch. Install a SPST switch in a location adjacent to each
passenger headset where cellphone use is desired. When pin M is connected to ground through any switch,
the passenger microphones are all on the Com 3/duplex system.

The hook switches are not active or required unless the audio panel is in Com 3 /Duplex mode, with pin J,
J2 grounded.

The wireless communication “tel” system utilizes an intercom loop. Therefore, any time the cellphone is in
use from the pilot or copilot side, pilot and copilot will lose intercom capability. In the ALL mode, when
the passengers’ activate the cell phone, the pilots will have intercom, and continue to hear and transmit
over the avionics normally. However the passengers will not have intercom, because they are on the tele­phone.

See section 2.5.14 for alternative connection for hook switches.

2.10 Post Installation Checkout

After wiring is complete, verify power is ONLY on pin 20 of the J1 (bottom connector), and airframe
ground on bottom connector pin Z. Failure to do so will cause serious internal damage and void PS Engi­neering's warranty.

2.11 Unit Installation

To install the PMA7000CD and PCD7100-R, gently slide the units into the mounting racks until the hold­down screws are engaged. While applying gentle pressure to the face of the unit, tighten the 3/32" hex­head in the center of the unit until it is secure. DO NOT OVER TIGHTEN.

Warning: Do not over-tighten the lock down screw while installing the unit in tray.

Internal damage will result.

2.11.1 Required Test Equipment

In order to return an aircraft to service after installation of the PMA8000-SR, the installer must have access
to a Marker Beacon signal generator:

a. IFR NAV401L, NAV402AP, IFR4000
b. TIC T-30D, T-36C

Equivalent test equipment is acceptable as long as the testing requirements can be met.

2.11.2 Operational Checkout

NOTE: The IntelliVox® is designed for ambient noise levels of 80 dB or above. Therefore some clipping
may occur in a quiet cabin, such as without the engine running, in a hangar. This is normal.

1. Apply power to the aircraft and avionics.

2. Plug headsets into the pilot, copilot, and occupied passenger positions.

3. Verify fail-safe operation by receiving and transmitting on com 1 from the pilot position, with the au­dio panel power off. The Com audio will be present in the right ear cup only.

4. Switch on the unit by pressing the volume (VOL) knob.

5. Check intercom operation.

6. Push the Com 1 Xmt select button (lower row).

7. Verify that both of the Com 1 buttons light. Verify that transmit button LED (Light Emitting Diode)

near the mic selector is not

blinking. If the LED is blinking, stop testing and troubleshoot the micro-

phone PTT installation.

8. Verify proper transmit and receive operation from the copilot position, noting that the copilot PTT
switch allows proper transmission on the selected transceiver. Verify thet the Com 1 Xmt button blinks
when transmitting.

9. Verify that pushing the C

OM 2 button causes the button to illuminate, and the Com 2 receiver to be

heard. Verify operation on Com 1 from the pilot position.

10. Repeat for Com 2 and standard Com 3, (if installed).

11. Press and hold the Com 1 Xmt button. While holding the Com 1 button, press the Com 2 Xmt button.
This places the unit in “split Mode;” Verify that the pilot can transmit and receive on Com 1, while the
copilot transmits and receives on Com 2.

12. If the audio panel is installed with J2, pin J grounded, it is configured for duplex operation on Com 3.
Verify that the pilot headset is connected to the cellular telephone system (if installed). Verify that by
using the pilot side PTT, the pilot can transmit on the other selected radio (Com 1 or Com 2). Verify
that the Com 3 Xmt LED blinks at about twice the rate of com 1, to indicate a duplex mode. The copi­lot has radio transmit capability in Com3 duplex mode, on the selected Com ( 1 or 2). However, he
will have Com 3 capability if the copilot hook switch is grounded.

13. Verify proper operation of all receiver sources by selecting them using the appropriate button. The
button illuminates to show which source is in use.

14. Push the SPR button. Verify that all selected audio is heard in the cockpit speaker. Verify that the au­dio mutes when the mic is keyed.

15. Verify that the appropriate LED in the lower right side blinks when either push to talk is keyed.

16. Verify proper Intercom system operation in the A

LL, ISO and CREW modes (see Table 3-1).

17. Verify that the audio selector panel system does not adversely affect any other aircraft system by sys­tematically switching the unit on and off, while monitoring the other avionics and electrical equipment
on the aircraft.

2.11.2.1 Marker Checkout

1. Connect a ramp generator at the antenna end of the marker coax. With the unit under test in HI sensi­tivity, verify that a 160 µV, modulated 95% with 1300 Hz, signal will illuminate the amber (M)
marker light, and that marker audio is present in the headphones when the Marker Audio (M) push­button has been depressed. Select SPR for speaker to verify marker audio availability on the cabin
speaker. Verify that the white (I) and blue (O) lights will illuminate within ± 3dB of the amber lamp,
with 3000 HZ and 400 Hz applied, respectively.

2. Repeat with the unit in LOW sensitivity, with 430 µVolts applied.

3. Connect the marker antenna and verify proper operation.

2.11.3 Receiver Sensitivity

Although the PMA7000M meets FAA TSO-C35d sensitivity specifications, the sensitivity of the receiver
has been adjusted to meet real world requirements (150µV and 430µV, soft). This will usually eliminate
the need for the avionics shop to reduce the sensitivity in the field so as to prevent early detection of the
marker beacons. If your particular installation requires more or less sensitivity, see adjustment section 2.6,
and figure 2-1.

2.12 Internal Recorder Checkout (Optional)

With headset plugged into pilot’s side jacks, tune COM 1 to local frequency, such as FSS or ATC ground.
Select Com 1 on mic selector switch, and record at least five incoming radio transmissions.

This audio should only appear in the pilot’s headset, and only be incoming transmissions from the trans­ceiver selected in the mic select switch.

Depress the panel or yoke mounted playback switch, and verify that messages play, in the order received.

Repeat for COM 2, and COM 3 (if installed).

2.13 Final Inspection

Verify that the wiring is bundled away from all controls and no part of the installation interferes with air­craft control operation. Move all controls through their full range while examining the installation to see
that no mechanical interference exists. Verify that the cables are secured to the aircraft structure in accor­dance with good practices, with adequate strain relief. Ensure that there are no kinks or sharp bends in the
cables and coaxial cables. Verify that the cables are not exposed to any sharp edges or rough surfaces, and
that all contact points are protected from abrasion.

Complete log book entry, FAA Form 337, weight and balance computation and other documentation as
required. Sample text for FAA Form 337, and instructions for continuing airworthiness can be found in

3.2 Power Switch (EMG-Fail Safe Operation)

Unit power is turned on and off by pushing the volume knob. In the

OFF or "EMG" position, the pilot is

connected directly to Com 1. This allows communication capability regardless of unit condition. Any time
power is removed or turned

OFF, the audio selector will be placed in the fail-safe mode.

The power for the CD player (PCD7100-R) is controlled by the audio panel. When the audio panel is on, it
automatically activates the player. If it is necessary to disable the CD player, hold the two CD buttons (far
right) in for more than 2 seconds. This removed power from the PCD7100-R circuits. To re-enable the
PCD7100-R, cycle power on the PMA7000CD.

The power switch also controls the audio selector panel functions, intercom, CD player and marker beacon
receiver, (PMA7000MS-CD only).

3.3 Microphone (XMT) Selection (All models)

There are six pushbuttons associated with the communications transceivers. The lower buttons control
which transceiver is selected for transmit.

The PMA7000CD gives priority to the pilot’s PTT. If the copilot it transmitting, and the pilot presses his
PTT, the pilot’s microphone will be heard over the selected com transmitter.

Installation and Operator’s Manual

PS Engineering

The PMA7000CD-Series has an automatic selector mode. Audio from the selected transceiver is automati­cally heard in the headsets and speaker (if selected). You can check this function by switching from C

OM 2 and watch the selected audio light on the selector change from COM 1 to COM 2. This ensures

to C

OM 1

the pilot will always hear the audio from the transceiver he is transmitting on.

When switching from C

OM 1 to COM 2, while COM 2 audio had been selected, Com 1 audio will continue

to be heard. This eliminates the pilot having to switch Com 1 audio back on, if desired.

When switching from C

OM 1 to COM 2 while Com 2 has NOT been selected, Com 1 audio will be switched

off. In essence, switching the mic selector will not effect the selection of Com receiver audio.

When the duplex, or TELEPHONE mode is implemented, Com 3 becomes the “TEL” position . This is the
pilot’s “hook” switch, when the system is interfaced to an appropriate approved wireless telecommunica­tion system, such as the AirCell system. Placing the mic selector in Com 3 places the pilot microphone and
headphones on the cellphone. The pilot PTT will switch the pilot mic to the other selected com transceiver,
and allow continued aircraft communications as well.

The copilot will also be able to transmit with his PTT as well.

NOTE: Placing the mic selector switch in the COM 3 –TEL– mode will disable pilot and copilot intercom,
as the intercom circuit is transferred to the telephone use. In crew or ISO mode, placing the switch in TEL
mode removes the passengers access to the telephone.

3.3.1 Swap Mode (Switch from Com 1 to Com 2 remotely)

With a yoke mounted, momentary switch, the pilot can change from the current Com transceiver to the
other by depressing this switch. To cancel "Swap Mode," the pilot may either press the yoke mounted
switch again, or select a different Com with the XMT buttons. .

3.4 Audio Selector (All models)

Receiver audio is selected through seven momentary, push-button, backlit switches. You will always

hear

the audio from the transceiver that is selected for transmit.

The users can identify which receivers are selected by noting which of the green switch LEDs are illumi-

nated. Push buttons labeled Nav 1, Nav 2, MKR (Marker), AUX (auxiliary), and SPR (Speaker) are "mo-

mentary type switches. When one of these buttons is pressed, be active, and the LED will illuminate. Press
the switch again and it be in the "off" position and remove that receiver from the audio.

If the aircraft is equipped with a DME or ADF, these audio sources can be selected with the AUX button.

3.4.1 Speaker Amplifier

The "SPR" in the push-button section stands for speaker. This switch will place all selected audio on the

cockpit speaker when this switch is selected. NOTE: Except for the unswitched audio, the speaker ampli­fier is not active in the "Split Mode."

Unswitched audio, (autopilot disconnect, altimeter warning, etc.) will come through the speaker regardless
of the speaker button position.

3.4.1.1 Public Address Function

To access PA function, a switch is installed to connect the top connector, pin 18, to ground. This places the

pilot microphone on the speaker output (Pin W) when the PTT is pushed. The copilot can continue to use

the selected com radio.

We recommend that the switch transfer the audio from the cockpit speaker to a cabin speaker for public
address. This will prevent feedback.

3.4.2 Key “Click”

The PMA7000CD is equipped with a “click” function that provides an aural feedback to the user in addi­tion to the tactile button push. This sound can be enabled or disabled by simultaneously holding the COM
1 and COM 2 buttons in for at least 5 seconds. Any person hearing the radios will also hear the key click.

Allow at least 20 seconds between turning the key click on and off.

3.5 Split Mode

The split mode can be activated at any time by pressing the desired combination of XMT buttons. For in­stance, to activate a Com 1/Com 2 split, press and hold the com 1 button, and then press the Com 2 button
while holding the Com 1 button. This places the pilot on Com 1 and the Copilot on Com 2.

Split mode for Com 3, in normal (not TEL/Duplex) is possible with pilot on Com 1, copilot on Com 2 or 3

Pilot on Com 2 or Com 3 and Copilot on Com 1 is not possible.

Note:

Due to the nature of VHF communications signals, and the size constraints in general

aviation aircraft, it is probable that there will be some bleed-over in the Split mode, par-

ticularly on adjacent frequencies.

PS Engineering makes no warranty about the suitability of Split Mode in all aircraft

conditions.

Note: Split Mode does not turn off other (Nav, ADF, etc.) selected audio to pilot. However, the copilot will only hear

the selected communications receiver.

3.5.1 Split Mode ICS

In split mode, the pilot and copilot are usually isolated from each other on the intercom, simultaneously

using their respective radios. Depressing the ICS button in Split Mode will activate VOX intercom be-

tween the pilot and copilot positions. This permits intercommunication when desired between the crew.
Pressing the ICS button again disables this crew intercom function.

3.6 Intercom Operation

3.6.1 IntelliVox® VOX-Squelch

No adjustment of the IntelliVox® squelch control is necessary. There is no field adjustment. Through three

individual signal processors, the ambient noise appearing in all six microphones is constantly being sam­pled. Non-voice signals are blocked. When someone speaks, only their microphone circuit opens, placing
their voice on the intercom.

The system is designed to block continuous tones, therefore people humming or whistling in monotone
may be blocked after a few moments.

For consistent performance, any headset microphone must be placed within ¼-inch of your lips,
preferably against them. (ref: RTCA/DO-214, 1.3.1.1 (a)).

It is also a good idea to keep the microphone out of a direct wind path. Moving your head through
a vent air stream may cause the IntelliVox® to open momentarily. This is normal.

The IntelliVox® is designed to work with normal aircraft cabin noise levels (70 dB and above). It
loves airplane noise! Therefore, it may not recognize speech and clip syllables in a quiet cabin,
such as in the hangar, or without the engine running. This is normal.

3.6.2 Intercom Volume Control

The volume control knob adjusts the loudness of the intercom for the pilot and copilot only. It has no effect
on selected radio levels, music input levels or passengers' volume level.

Adjust the radios and intercom volume for a comfortable listening level for the pilot. Most general aviation
headsets today have built-in volume controls; therefore, passenger volume can be adjusted at the headset. If
desired, passenger volume level can be adjusted by a screwdriver adjustment at the top of the tray (see fig­ure 2-1).

3.6.2.1 Mono headsets in Stereo Installation

All passenger headsets are connected in parallel. Therefore, if a monaural headset is plugged in to a
PMA7000CD Stereo installation, one channel will be shorted. Although no damage to the unit will occur,
all passengers will lose one channel, unless they switch to the “MONO” mode on the headset. PS
Engineering modifies headsets to add stereo capability, using high-fidelity speakers. Contact factory for
details.

3.6.3 Intercom Modes

The lower switch on the left side is a 3-position mode switch that allows the pilot to tailor the intercom
function to best meet the current cockpit situation. The description of the intercom mode function is valid
only when the unit is not in the "Split" mode. Then, the pilot and copilot intercom is controlled with the
ICS button.

SO: (Up Position): The pilot is isolated from the intercom and is connected only to the aircraft radio sys-

I

tem. He will hear the aircraft radio reception (and sidetone during radio transmissions). Copilot will hear
passengers’ intercom and Entertainment 1, while passengers will hear copilot intercom and Entertainment

2. Neither will hear aircraft radio receptions or pilot transmissions.

LL: (Middle Position): All parties will hear the aircraft radio and intercom. Crew will hear Entertainment

A

1, passengers will hear Entertainment 2. During any radio or intercom communications, the music volume
automatically decreases. The music volume increases gradually back to the original level after communica­tions have been completed.

PMA7000CD Audio Selector Panel and Intercom System

With PCD7100-R Remote Compact Disc Player

Installation and Operator’s Manual

PS Engineering

CREW (Down Position): Pilot and copilot are connected on one intercom channel and have exclusive ac-

cess to the aircraft radios. They may also listen to Entertainment 1. Passengers can continue to communi­cate with themselves without interrupting the Crew and also may listen to Entertainment 2.

Anytime the PMA7000CD is in either the C

OM 1/COM 2, COM 2/COM 1 ("Split Mode"), the pilot and copi-

lot intercom is controlled with the ICS button. The passengers will maintain intercommunications, but
never hear aircraft radios.

3.6.3.1 Entertainment Input

The audio selector panel has provisions for two separate entertainment input devices. The PCD7100-R
remote CD player is usually installed as Music 1, and feeds the pilot and copilot positions. They operate
independently in the PMA7000CD. The music volume control affects the PCD7100-R music level only in
the pilot and copilot positions.

While in the ISO (Isolate) mode, the copilot will hear Entertainment 1 while the four passengers will hear
Entertainment #2. The pilot will hear entertainment 1, at a muted level. In normal operation, whenever a
person speaks, or if the aircraft radio becomes active, the music will automatically mute and then will
gradually return to the original listening level when the intercom or radio conversation ceases.

When in the A
Entertainment 2 source. While in the C

LL mode, pilot and copilot will hear Entertainment 1 input while all passengers will hear the

REW mode, pilot and copilot will hear entertainment input #1 while

the passengers may listen to entertainment input #2.

It is also possible to use just the PCD7100-R as entertainment input device for both entertainment inputs.
However, we suggest that a switch (DPDT) be installed between PCD7100-R entertainment input #1. This
will allow the pilot to direct the music as desired.

3.6.3.2 Soft Mute and Soft Mute inhibit

The Soft Mute feature assures that the aircraft radio transmissions will not be missed due to entertainment
playing. When there is radio reception or intercom conversation, the music level is dropped to a low, or
background level. When the radio or intercom traffic ceases, the level gradually returns to normal.

The front panel ICS switch controls muting of entertainment source #1 (for pilot and copilot). Pushing this
button places the ICS in Karoake (or sing along) mode, which inhibits the soft mute feature. This allows
the music to continue uninterrupted by intercom or radio traffic when cockpit workload is appropriate.
Pushing the button again will release the mute inhibit function.

The passenger music, source #2, can be placed in the Karoake mode if a remote switch is installed in the
aircraft. See wiring information for details.

themselves.

3.7 Telephone Mode

The Com 3 mode can serve as a full duplex interface for telephone systems if the installation is correctly
configured. When interfaced with an approved airborne telecommunications system, the PMA7000CD can
serve as a audio control and distribution center. Each intercom position has a "hook switch." The pilot's
hook switch is the "Com 3" button on the audio panel, the others are discrete switches mounted adjacent to
the headset jacks. When Com 3 is active in the duplex mode, the TX button will blink about twice as fast
as the normal transmit rate.

When the intercom is in ALL mode, the pilot can speak on the phone only

if the Com 3 is selected for

transmit (Com 3 Xmt button activated). All intercom positions will hear the telephone conversation. If

any passenger places his or her switch into the “off-hook” position all passengers will also be heard on the
phone. All will hear selected audio. Com 1 audio is automatically heard in the headsets. The pilot and copi­lot will have transmit capability on the other selected transceiver Com 1 or 2, simply by using their respec­tive PTT switch.

In CREW mode, the pilot and copilot are may use the telephone, with their respective hook switch (the

pilot selects Com 3 on the Xmt selector). Any passenger who places their switch into the off-hook position
will also have access to the phone, and all four passengers will hear the conversation.

In ISO intercom mode, when the PMA7000CD is in the Com 3 mode, the pilot position is in the "Phone

Booth." Only the pilot will hear the telephone, and only he will be heard. He will also have access to Com
1 or 2, and will transmit on that radio using the PTT. All selected audio is provided. If any other passenger
goes “off hook” they will hear the phone.

Note: Because the cellphone uses an intercom circuit, all stations on that circuit will lose

intercom capability when the cellphone is in use.

The two push buttons at the far right of the PMA7000CD Option CD control the compact disk operation.
Inserting the disc into the remote player unit (PCD7100-R, part number 11959) will automatically begin
play.

The lower button (play/pause/advance) is used to play the disc from stop, pause play, and advance the
track. When the disc is stopped, pushing the button starts play. A short push will pause play. A longer
press advances the track. Holding the button acts as a intro/scan, playing the first two seconds of each track
until released.

The top button is used to stop and eject the disc. Press momentarily to stop, press and hold to eject.

There is no backup mode available in these units

Holding BOTH buttons in for more than two seconds will cause the CD player to power down.

NOTE: In order to restore CD operation you must cycle power on the PMA7000CD.

3.9 Marker Beacon

The optional Marker Beacon Receiver uses visual and audio indicators to alert you when the aircraft passes
over a 75 MHz transmitter.

The Blue lamp, labeled "O," is the Outer Marker lamp and has an associated 400 Hertz 'dash' tone. The
lamp and tone will be keyed at a rate of two tones/flashes per second when the aircraft is in the range of the
Outer Marker Beacon.

The Amber lamp, labeled "M," is the Middle Marker lamp and is coupled with a 1300 Hertz tone. It is
keyed alternately with short 'dot' and long 'dash' bursts at 95 combinations per minute.

The White lamp, labeled "I," is the Inner marker and has a 3000 Hertz 'dot' tone. The lamp and tone will be
keyed at a rate of six times per second.

The audio from the Marker Beacon Receiver can be heard by selecting the "MKR" push-button switch. To
adjust the volume level, there is a service adjustment located on the top of the unit.

A three-position switch is used to set the receiver sensitivity and to test the indicator lamps. Use "HI" sen-
sitivity initially. This allows you to hear the outer marker beacon about a mile out. Then select the “LO”

sensitivity to give you a more accurate location of the Outer Marker. The momentary down switch position
is marker test, labeled "T/M" and illuminates all three lamps simultaneously to assure the lamps (internal
and external) are in working order. TST does not activate MM sense output.

Pressing the marker mode select down (to “T/M”) will cause the marker audio to mute for that beacon. The
next beacon received will re-activate the audio.

3.10 Internal Recorder System (Optional)

The Intercom Recording System (referred to here as the IRS) is a digital recording system allowing auto­matic storage and playback of aircraft radio traffic.

Operating as a continuous loop recorder, (first message received will be the last heard), the recorder has
one minute of recording time or up to 16 messages. With its own built in VOX circuit, there are no buttons
to press to start recording. The system automatically begins to record the instant the radio becomes active.
Only aircraft radio audio in pilots headset is recorded and only the pilot will hear the playback audio.

3.10.1 Operation

Recording is automatic; there is no action required by the pilot. To play back the last recorded message,
simply press the momentary switch associated with the IRS. Each additional press of the button will play
the preceding recorded message. You must wait for the message to finish playing before accessing the
prior message.

To cancel the playback, press and hold the playback button for two seconds. The next time the button is
pressed, the next earlier message will be heard.
