This pilots guide provides operating instructions for the PMA8000B Audio
Panel. Please read it carefully before using the equipment so that you can
take full advantage of its capabilities.
This guide is divided into operating sections such as Transceiver Selection,
Audio Selector, Intercom, and Marker Beacon Receiver, and special functions. The center section provides a handy reference that you can remove.
PMA8000B controls
Power Switch (1) (EMG-Fail Safe Operation)
The power switch controls all audio selector panel functions, intercom and
marker beacon receiver.
When the unit is turned off, either by pressing the volume control, or if the
breaker is pulled removing power, the PMA8000B is in Fail-Safe mode. In
this mode, the pilot’s headset is connected to COM 1 for transmit and receive, and connected to unswitched input #1 for priority audio alerts. The fail
safe audio will only be heard in the left ear of a stereo headset.
Receiver selection
Transmitter selection
Selection (2)
To select Com 1 or Com 2 for transmit, press the
button on the bottom row, next to the XMT legend. The bottom and top button indicators light,
showing that you will transmit and receive on
the selected radio.
Communications Receive (RCV) Selection (4)
To listen to the other radio, press the upper button, in the RCV (receive) section. When a com is selected for receive, it will stay selected until manually
deselected, even if you select, and then deselect its transmitter.
Page 2 202-890-0202 PMA8000B Pilot Guide Rev. 6
Communications Transmit (XMT)
Unless the audio panel is in “split” mode, the PMA8000B gives priority to
the pilot’s radio Push-To-Talk (PTT).
If the Monitor function is activated, the audio from this radio will be muted
when the primary radio (selected for transmit) is receiving a signal.
In TEL mode, the pilot is connected to the cell phone, but still hears the
COM radios selected. The radio PTT will switch the mic to the selected com,
and allow continued aircraft communications to continue. (See Page 6—
TEL—for more details)
Audio Selector (4)
These buttons select the
switched navigation receivers.
The DME input (if present) is
also shared with AUX. In SPLIT
mode, only the pilot will hear
selected navigation audio.
Cockpit Speaker (5)
This switch will place all selected audio on the cockpit
speaker when this switch is selected. In “Split” mode, the
speaker carries the same audio as the pilot.
Depending on installation, important audio alerts such as
radar altimeter or autopilot disconnect will come over the speaker even if it
is not selected, while other unswitched inputs, will only be present if the
SPR button is selected. Consult your professional avionics installer for these
important configuration details.
Intercom Operation
IntelliVox® VOX-Squelch
IntelliVox® is PS Engineering’s proprietary intercom squelch control.
Through the use of digital processors, each microphone is monitored, and
opens instantly when human speech is detected. This results in seamless conversations aboard the airplane for crew and passengers, without syllable clipping or fatigue-inducing noise.
No adjustment of the IntelliVox® squelch control is necessary. There is no
field adjustment. 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,
May 2012 PMA8000B Pilot Guide
202-890-0202 Page 3
and not twisted inside the cover.
Note: For optimum microphone performance, we recommend use of a Microphone Muff Kit from Oregon Aero (1-800-888-6910,
www.oregonaero.com
).
This will not only optimize VOX performance, but will improve the overall
clarity of all your communications.
You should also keep the microphone out of a direct wind. Moving your
head through an 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). Therefore, it may not always recognize
speech and clip syllables in a quiet area, such as in the hangar, or without the
engine running. This is also 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 for the passengers. It has no effect on radio or music levels.
Mono Headsets in Stereo Installation
The pilot and copilot positions work with stereo or mono headsets. If a monaural headset is plugged in to a PMA8000B Stereo installation, one channel
will be shorted and all passengers will lose one channel unless they switch to
the “MONO” mode on the headset.
Intercom Modes (8)
The intercom has three 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 Mute button.
This button cycles through the intercom modes, from top to bottom and then
back up.
I
SO: The pilot is isolated from the intercom and is con-
nected only to the aircraft radio system. He hears the radios (and sidetone during radio transmissions). The copilot
and passengers will hear the music sources as configured
by the audio panel configuration Function keys. See page
11—Smart Function Keys for more details.
While in ISO Mode, the pilot can elect to hear music #1. First, be sure that
the ISO mode is selected. Then press and hold the TEL button, then hold the
ICS mode button for more than one second. The ICS indicator will blink
slowly to indicate music is present in ISO. The music muting will be the
selected mode.
Page 4 202-890-0202 PMA8000B Pilot Guide Rev. 6
ALL: All parties will hear the aircraft radio and intercom. Crew will hear
Music 1, passengers can hear Music 1 or 2. The music mutes in accordance
with the muting mode selected.
C
RW: (Crew) Pilot and copilot are connected on one intercom channel and
have exclusive access to the aircraft radios. The passengers have their own
intercom. The music that the crew and passengers will hear is determined by
the Smart Function Keys.
Marker Beacon Operation (9)
The Marker Beacon Receiver uses visual
and audio indicators to alert you when the
aircraft passes over a Beacon transmitter.
The Blue, Outer Marker lamp 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.
The Amber, Middle Marker lamp is coupled with a 1300 Hertz tone, keyed
alternately with short 'dot' and long 'dash' bursts at 95 combinations per minute.
The White, Inner marker lamp has a 3000 Hertz 'dot' tone, and will be keyed
at a rate of six times per second.
Marker Beacon Receiver audio can be heard by selecting the "MKR" push-button switch. There is a service
adjustment located on the top of the unit to adjust the
volume if desired.
The MKR button located next to the indicator lights is
used to set the receiver sensitivity and to test the indicator lamps mute the
marker audio.
Pressing the MKR button for one second will cause
the marker audio to mute. The next beacon received
will re-activate the audio.
Holding the MKR button for one second also activates marker test, labeled "T/M" and illuminates all three lamps simultaneously to confirm the lamps (internal and external) are working. Releasing the
button returns to the last sensitivity.
Split Mode
To activate the split mode, push both the COM 1
and COM 2 XMT (bottom) buttons at the same
time. All four indicators will come on. In the
split mode, the pilot is on COM 1, while the
copilot is on COM 2.
May 2012 PMA8000B Pilot Guide
202-890-0202 Page 5
Select either of the com XMT buttons to exit the split mode. It is not possible
to have the pilot on Com 2 and copilot on COM 1 in split mode. In the split
mode, the intercom is disabled, and the MUTE indicator is on. Push MUTE
to enable the intercom if desired.
NO T E: 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.
Telephone (TEL) (10)
The TEL mode serves as a full duplex interface and distribution
for telephone systems such as portable cellular phones with earpiece jacks. Pressing the button 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.
In ISO intercom mode, 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. Selected radio audio is provided to the pilot.
In cases where the cellular telephone doesn’t provide sidetone, the audio
panel can be configured, by holding the TEL and ADF buttons for more than
one second, to create sidetone for you.
Stuck Microphone Protection
The PMA8000B will sense if the pilot or copilot radio PTT remains keyed
for more than 32 seconds. When a stuck mic is detected, the key input is
ignored, and the other crewmember can transmit normally. If the stuck becomes ungrounded, normal operation is restored.
Utility Jack
The 2.5 millimeter (3/32”) jack on the front of the PMA8000B has three distinct functions, cell phone input, Advisory audio input and music input
(Continued on page 11)

Quick reference PMA8000B Operation
This pull-out section covers advanced operation of the PMA8000B.
Split Mode
The Split mode puts the pilot on COM 1, while
the copilot can use COM 2 independently. To
enter the split mode, press both the COM 1 and
COM 2 XMT buttons at the same time. To exit,
press the desired COM 1 or COM 2 XMT button.
When you activate the Split mode, the intercom
is inhibited to avoid confusion with multiple conversations. To
reactivate the intercom, press the Mute button.
Note: Split Mode does not turn off Nav, ADF, or Aux selected audio
to pilot. However, the copilot will only hear the selected com receiver
and unswitched inputs.
Telephone Operation
When the TEL button is active, the cellular telephone is added to the
intercom loop, and who is connected to the phone depends on the intercom mode.
You can answer a call by pushing the TEL button while it is ringing.
Calls can be answered from the telephone handset or the audio panel.
You can disconnect from either the handset or the audio panel. When
a call is disconnected or dropped, the TEL button indicator will extinguish after a few moments.

The pilot can elect to listen to Music 1, even in the Pilot Isolate mode.
While already in the ISO mode, press and hold the ISO button until
the indicator blinks. The ICS indicator will then blink every few seconds to indicate this mode is active. Music muting will follow the
modes listed above.
Smart Function Keys (SFK) Configuration
Secondary functions give the PMA8000B some special capabilities.
“Intercom” allows the passengers and crew to converse, in ALL intercom mode, without distracting the crew from radio duties. The passenger microphones are cut out from the crew when the radio is active, and the passengers never hear aircraft radios. Press and hold the
TEL button until the audio annunciation starts (about 1 second) to
activate the function, and you will hear “Alternate Intercom Function.” Hold the button again to exit, and you will hear “Standard Intercom Function.”
“Monitor” activates a Monitor Mode. In this case, the audio from

audio when it is active. For example, if COM 1 is selected to transmit
to ATC, but COM 2 is receiving weather information; the ATC will
mute the audio from the weather while ATC is transmitting. In Monitor mode, the RCV COM indicator will blink every few seconds as a
status indication. Monitor mode is set to off when the unit is turned
off.
“Music” controls music distribution, and has three states; Standard
Music Distribution, Alternate Music Distribution and Music 1 All
Headsets.
Music 1 (Music 1 input on the rear connector) can be distributed to all
headsets depending on intercom mode.
In Standard Music Distribution, Music 1 is provided to the crew, and
Music 2 is independently provided to the passengers.
In Alternate Music Distribution, Music 1 is provided to everybody in
the ALL intercom mode, and Music 2 becomes active, for the passengers only, when the intercom is in the CREW mode. The front panel
jack is also available to the passengers in the ISO and ALL intercom
modes.
The PMA8000B will announce the Alternate Intercom and Music
distribution functions at unit power up. To defeat the announcement at
power up, hold the TEL and AUX buttons for about two seconds.
The feature can be enabled using the same sequence.

“Smart” Front Panel Jack
When music 1 is actively playing through the rear panel input, the
front jack automatically becomes an advisory audio input, and is NOT
muted by radio or intercom conversations. This is useful for connecting portable traffic or terrain alert devices. If Music 1 is not active, the
mute mode should be deselected.
Recorder Playback
The internal recorder is always storing the audio from the radio selected for transmit. To play back the last incoming audio, hold the
RCV (top) button on the radio selected
to transmit for one second, and release.
The playback will start. Playback stops
if the radio becomes active, but the new
incoming message will not be recorded.
When the radio stops, press play and you
will be in the same message you had
playing.
To hear an earlier message, hold the COM RCV button until playback
stops again, and then press again to begin playing the next earlier
message. Repeat until you hear the message you wanted. Incoming
new messages will stop playback, and you can then restart.
A remote playback switch may also be installed.
Note: when you switch from one transmitter to another, the recordings
are lost.

(Continued from page 6)
Cellular phone
When a cellular telephone is connected to this jack using an adapter cord (PS
Part Number 425-006-7026), the PMA8000B audio panel will connect the
intercom to the cell phone when the “TEL” button is pressed (9). When the
TEL mode is off, the telephone ringer audio will be heard if it is present on
the telephone’s output (ringer may be muted by radio and intercom).
Audio Advisory Input
The front jack can be used as a priority advisory input for auxiliary systems
such as a GPS terrain advisory or portable traffic watch system. To prevent
radio or intercom from muting this input, press the “Mute” button.
NOTE: The front jack is no substitute for the certified installation of alerts
such as the GPS waypoint or autopilot tones. These still must be hard wired
into the back by your installer.
“Smart Jack” Function
When the PMA8000B has an audio signal on music #1 from the rear connector, the front panel jack automatically becomes a Priority Advisory input,
and is heard in the crew headphones, and this input will NOT be muted by
radio or intercom., if the Music 1 audio is actively playing.
Music Input
When used as a music input, the front panel jack music are treated as Music
#1. Using the Music function button, it can be distributed to all users, depending on the intercom mode.
Smart Function Keys
(SFK)
With voice feedback, the configuration process is self-directed. These functions are non-essential and non-required and as such are only an accessory
capability. Note: annunciations will be stopped by any audio received on the
com radio selected for transmit.
Looking at the front panel you’ll notice that the TEL, AUX, Mute and SPR
buttons have “Function” assignments.
To use these function keys Intercom, Monitor, and Music – press and
hold the desired function key until the audio annunciation of the mode begins. NOTE: SFK are not available in the split mode.
There are three special functions. “Intercom” function is related to the intercom audio distribution, and allows the crew to mute passengers’ intercom
feed when radios are active.
May 2012 PMA8000B Pilot Guide
202-890-0202 Page 11
The “Monitor” function mutes the secondary communication radio audio
when the primary radio (the one selected to transmission) is active.
“Music” function controls how music is distributed in your airplane.
There are two music sources available to the PMA8000B, Music 1 input can
be either on the front jack, or the Music 1 input at the rear connector (Pins 23
and 24, J2). Music 2 is wired into the rear connector, only (Pins 26 and 27,
J2)
The volume of the function selection annunciations and recorder playback
can be adjusted through a hole on the top of the unit marked “ANN VOL.”
“Intercom” Function
Intercom function controls the distribution of aircraft radio and pas-
senger intercom. In the “Standard intercom function” mode, aircraft
radios are distributed to all, when the intercom is in the ALL mode.
In CREW mode, only the pilot and copilot positions will hear aircraft radios.
When in “Alternate Intercom Function,” the passengers will NEVER hear
aircraft radios, even in the ALL mode. In addition, when in the ALL intercom mode, passengers will be able to converse with the crew, unless the
aircraft radio becomes active, when the intercom audio from the passengers
to the pilot and copilot is stopped, so the crew can focus on the radio. Passengers will always be able to talk to each other.
To activate this function hold the TEL button until the audio announces
“Alternate Intercom Function,” when activated, and “Standard Intercom
Function” when deactivated.” The alternate intercom mode is announced at
power up, unless the power on announcement has been defeated.
“Monitor” Function
This function turns the Monitor Function on and off.
When the Monitor is on, the audio from the COM that is selected
for reception
the radio that is selected to transmit becomes active.
This function is useful if you are copying weather from AWOS on
COM 2, but have clearance delivery tuned in on COM 1. With the monitor
active, the AWOS audio will be silenced when clearance delivery starts to
speak.
To activate the Monitor Function press and hold AUX. The audio will announce “Monitor on,” when activated, and “Monitor off” when deactivated
NOTE: This mode is NOT remembered through power cycles, to
prevent inadvertent blocking of desired audio on the next trip.

“Music” Distribution Function
The Music Function has three modes. To cycle Music distribution
modes, press and hold Mute button until the annunciation starts.
Page 12 202-890-0202 PMA8000B Pilot Guide Rev. 6
When “Music number one, all headsets” is selected, Music 1 from the rear
connector) will be distributed to all headsets and is independent of the intercom mode switch. Therefore, even in the CREW mode, the passengers will
hear Music 1, although though they will not hear the crew intercom or radios.
This mode allows you to use a single in-flight entertainment source. The
music muting follow the selected mode of the crew and passengers.
When you press “Music” function again, you’ll hear, “Alternate music distribution.”
This function makes Music 2 dependent on the intercom mode.
In this state, Music 2 will be heard only when the intercom is in the CREW mode,
and only the passengers will hear it. Music 1 (Rear input, and Front Panel Jack) will
be provided to passengers’ headset in ISO and ALL intercom modes.
Press again, and you will hear “Standard Music Distribution.” In this mode, Music 2
becomes active, and will always be presented to the passengers. Music 1 is only
available to the pilot and copilot. The intercom mode switch will not have any affect
on the music distribution.
When the music is in “Standard music distribution,” Music 1 will always go
to the pilot and copilot positions, and is never heard by the passengers. Music 2 is always heard by the passengers, and never heard by the pilot and
copilot.
This mode is useful if your passengers have a different interest in entertainment or are watching a DVD, but do not want to be excluded from the intercom conversations.
Alternate Music distribution modes are announced at power up, unless the
power on announcement has been defeated.
Power on announcement
If the Intercom or Music Distribution is changed from the factory default,
the configuration will be played when the unit is powered up. To defeat this
announcement, hold the TEL and AUX buttons for two seconds. The feature
can be enabled using the same sequence.
Music Muting
There are two SoftMute™ muting circuits. The front
panel "Mute" button has four modes, and controls the
Mute function for music 1.
The SoftMute™ circuit will cut the music out whenever there is conversation on the radio, the intercom, or
both, depending on the “Mute” mode selected. When
that conversation stops, the music returns to the previous level comfortably, over a second or so.
The mute mode functions are controlled through sequential pushes of the
Mute button, and include voice annunciations of the mode selected.
• Mute On - music will

When the PMA8000B is turned on, it always begins in “Mute on” mode.
The passengers’ intercom also has a SoftMute™ circuit. If the passengers
hear the radio, or talk on the intercom, the music will mute. If the audio
panel is in CREW mode, then the radio reception will not affect the passenger music.
If the passengers are listening to the music 1 input or front panel input, their
Karaoke Mode is controlled by the front panel “Mute” button. If the passengers are listening to the music 2 input, their Karaoke Mode is activated by an
external switch installed either in the aircraft, or connected to the AUX button logic output pin on the PMA8000B. Consult your installer for details.
mute mu-
Music 1 Volume
The music level is set at the factory at a comfortable level.
We recommend adjusting the entertainment volume at the
sources. However, the Music 1 volume can be adjusted from
the front panel, if desired, by pressing SPR button.
NOTE: Increasing this music level can increase the amount
of aircraft electrical system noise as well.
The Music 1 volume can be adjusted from the front panel, if desired, by
pressing and holding the Music Volume (SPR) key.
Press the Music Volume (SPR) for more than one second, a tone will be
heard indicating the volume level is changing and the music volume will
begin to change. The volume will either increase or decrease, depending on
the last action. To reverse the volume change, release the Music Volume
(SPR) button, and press and hold again, and the volume will change. Continue to hold until the desired level is reached.
Note: Since it is possible to turn the volume completely off, you may need to
turn the volume up if you don’t hear music when you expected to.
It will take about 12 seconds to go from minimum to maximum volume.
Swap Mode (Switch from Com 1 to Com 2 remotely)
The “swap” button allows you to switch between the COM transmitters
without having to reach up to the audio panel, and is a handy way to switch
to Ground Control when exiting the runway. This optional switch is usually
mounted on the control yoke or a convenient place by the pilot position.
Page 14 202-890-0202 PMA8000B Pilot Guide Rev. 6
Internal Recorder System
The Intercom Recording System is a continuous loop recorder, (last message
received will be the first heard), the recorder has 45 seconds of recording
time, or up to eight messages. There are no buttons to press to start recording. The system automatically begins to record the instant the radio selected for transmit becomes active. Only the pilot and copilot will hear the
playback audio.
To play back the last recorded message,
you press and hold the COM RCV
pushbutton associated with the selected
radio transmitter for about one second.
You must wait for the message to stop
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 for one second, the next earlier message will be heard. If the radio
becomes active while a message is playing, the message playback will stop.
The new audio will not be stored. Press play to restart the message you were
playing.
Messages are lost when a different radio is selected for transmit.
The playback will stop whenever there is more incoming selected com audio,
and the message can be replayed from the beginning. Note: an external playback button may also be installed in a convenient location.
Public Address Function (if enabled)
To enter PA mode, press both the Mute and SPR buttons at the same time.
The Mute and SPR LEDs will blink to indicate the audio panel is in PA
mode. The copilot can continue to use the selected com while the pilot will
be heard over the speaker. To exit push Mute and SPR again. This mode is
also reset when power is cycled.
Backlighting
The white text backlighting is controlled by the aircraft dimmer, while the
green indication LEDs are automatically controlled by the light sensor on the
PMA8000B.
