The PMA8000 “remembers” the receiver selection, so that when switching transmitters from C C
OM 1 audio will continue to be heard. This eliminates the pilot having to

switch Com 1 audio back on, after changing transmitters.
When switching from C lected, C
OM 1 audio will be switched off. In essence, switching the mic selec-
OM 1 to COM 2 while Com 2 was not previously se-
tor will not override prior selection of COM receiver audio.
In normal (not split) modes, the PMA8000 gives priority to the pilot’s radio Push-To-Talk (PTT). If the copilot it transmitting, and the pilot presses his PTT, the pilot’s microphone will be heard over the selected com transmitter.
In TEL mode, the pilot microphone and headphones are connected to the cell phone. The pilot PTT will switch the pilot mic to the selected com transceiver, and allow continued aircraft communications to continue.
The copilot will also be able to transmit on the other selected radio with his PTT as well.
Split Mode
The split mode can be activated at any time by pressing the C
OM 1 and COM 2 XMT buttons at the same time.
This places the pilot on C

OM 1 and the Copilot on COM 2.
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, particularly 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 Nav, ADF, or AUX selected audio to pilot.
However, the copilot will only hear the selected communications receiver.
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.
Factory Service
The units are covered by a three-year limited warranty. See warranty informa­tion. Call PS Engineering, Inc. at (865) 988-9800 before you return any unit.

Audio Selector (4)
Navigation receiver audio is selected through five momentary, push-button, backlit switches. You will always
hear the audio from the selected transceiver.
202-890-0000 3 PMA8000-Series Pilot Guide
The users can identify which receivers are selected by noting which green switch LEDs are lit. Navigation aid audio push buttons are labeled Nav 1, Nav 2, MKR (Marker), ADF and AUX (auxiliary). DME audio (if present) will come through when the AUX button is selected. When one of these buttons is pressed, the mode is active, and the LED will illuminate. Press the switch again and it will be "off" and remove that re­ceiver from the audio output.
In SPLIT mode, only the pilot will hear selected navigation audio.
Telephone (TEL) (9)
The TEL mode serves as a full duplex interface and distribution for telephone systems such as AirCell or portable cellular phones with earpiece jacks. Press­ing the TEL button activates the telephone mode. This connects the telephone to the users as follows:
In ALL intercom mode, all crew and passengers will be heard on the phone when they speak. Com and other selected radio audio is also heard in the head­sets. If the pilot or copilot pushes the radio PTT, their mic will be transferred to the selected Com radio. The telephone party will not hear ATC communica­tions, and vice versa.
In CREW mode, only the pilot and copilot are connected to the telephone.
Passengers will not hear the telephone. The pilot and copilot will also have transmit capability on the other selected transceiver.
In ISO intercom mode, when the PMA8000 is in the
TEL 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 to the pilot.
Note: Because the cellphone uses an intercom circuit, all stations on that circuit will lose intercom capability when the cellphone is in use.
Speaker Amplifier (5)
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, (the four inputs dedicated to autopilot disconnect, altimeter warning, etc.) will come through the speaker regardless of the speaker button position.

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 pushbutton is used to set the receiver sensitivity and to test the indicator lamps mute the marker audio.
Use "HI" sensitivity initially. This allows you to hear the outer marker beacon about a mile out. Then touch the smaller MKR button to switch into Low Sen­sitivity mode. “LO” sensitivity gives you a more accurate location of the Outer Marker. Holding the MKR button for one second activates marker test lamp, 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 autopilot sense output. Releasing the button returns to the last sensitivity.
Pressing the marker mode select (“T/M”) for one second will also cause the marker audio to mute for that beacon. The next beacon received will re-activate the audio.
Optional Internal Recorder System (Option 1)
The Intercom Recording System 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 pilot’s headset is recorded and only the pilot will hear the playback audio.
Operation
Recording is automatic. To play back the last recorded message, simply press the 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.

REW: Pilot and copilot are connected on one intercom channel and have ex-
clusive access to the aircraft radios. They may also listen to Entertainment 1. Passengers can continue to communicate with themselves without interrupting the Crew and may listen to Entertainment 2.
Entertainment Input and muting control
Public Address Function
To access PA function, press the Mode and SPR buttons simultaneously. The COM1 and COM2 RCV LEDs will blink to indicate the audio panel is in PA
mode. The copilot can continue to use the selected com radio while the pilot will now be heard over the speaker.
To exit PA mode, push Mode and SPR again.
The PMA8000 has provisions for two entertainment devices. Entertainment #1 is heard by the pilot and copilot (crew) , and Entertainment 2 is heard by the passengers. The ICS pushbutton has no effect on these music inputs, allowing independent entertainment from the mode of the intercom. The intercom vol­ume control does not
While in the ISO (Isolate) mode, the copilot will hear Entertainment #1 while the four passengers will hear Entertainment #2. The Enter­tainment #1 will mute when either the copilot or pilot speaks, and Entertainment #2 mutes when the passengers speak. With our Soft Mute™ , the music will return gradually to the original listening level when the intercom or radio conversation ceases. While in ISO mode, the Pilot will not mute the music if he presses the PTT switch to trans­mit or if he speaks while on the phone.
The entertainment inputs automatically mute when there is radio traffic or in­tercom conversation. In many cases, the muting is not desired, so mute inhibit, or “Karaoke Mode” is available. This is accomplished for the crew by pressing the “Mode” pushbutton. Thee unit can be wired so that AUX will put the music 2 music into Karaoke mode for the passengers.

affect the music level.
Marker Beacon Operation (10)
The Marker Beacon Receiver uses visual and audio indicators to alert you when the aircraft passes over a 75 MHz transmitter.
Intercom Operation
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 important to have the microphone element parallel to your mouth, and not twisted inside the cover.
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.
Intercom Volume Control (7)
The small volume control knob adjusts the loudness of the intercom for the pilot and copilot. It has no effect on selected radio levels, music input levels or passengers' volume level.
The larger, outer volume control knob controls inter­com volume or the passengers. It has no effect on radio or music levels.
8 202-890-0000 PMA8000-Series Pilot Guide
Adjust the radios and intercom volume for a comfort­able listening level. Most general aviation headsets
202-890-0000 5 PMA8000-Series Pilot Guide
today have built-in volume controls; therefore, volume also can be further ad­justed at the individual headset.
For optimum microphone performance, PS Engineering recommends
installation of a Microphone Muff Kit from Oregon Aero (1-800-888-
6910). This will not only optimize VOX performance, but will improve the overall clarity of all your communications.

Mono headsets in Stereo Installation
All passenger headsets are connected in parallel. Therefore, if a monaural headset is plugged in to a PMA8000 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.
Intercom Modes (8)
The “ICS” pushbutton switch on the left side of the panel provides the selec-
tion of the three intercom modes. 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 Mode but­ton.
