This pilot guide provides detailed operating instructions for the PS
Engineering PMA8000B, Audio Selector Panel/Intercom Systems.
This unit was developed exclusively for Avidyne for use with Ente-
gra Integrated Avionics System Release 9. Please read it carefully
so that you can take full advantage of its capabilities.
This publication covers the basic operating areas of the PMA8000B
systems. They are Com Transceiver Selection, Audio Selector, Inter-
com, and Marker Beacon Receiver, utility jack and the configuration
buttons.
PMA8000B controls
Power Switch (1) (EMG-Fail Safe Operation)
Unit power is turned on and off by pushing the volume knob. In the
OFF or "EMG" position, the pilot headset is connected directly to
Com 1 as well as unswitched input #1. This allows communication
capability regardless of unit condition. Any time power is removed or
turned OFF, the audio selector will revert to fail-safe mode.
The power switch controls all audio selector panel functions, inter-
com and marker beacon receiver. All pushbutton selections will be
remembered and return to the last state when turned on.
Communications Transmit (XMT) Selection (2)
There are two pushbuttons associated with the transmitter selection.
The two lower buttons (# 2) control which transceiver is selected for
transmit. The top row of pushbuttons (# 3) allows selection of the re-
ceiver audio. Push the lower button to select the desired COM trans-
mitter.
The PMA8000B-Series has an automatic selector system. Audio from

202-890-0402 Rev. 2 Page 3Oct. 2010 PMA8000B Pilot Guide
the selected transceiver is automatically heard in the headsets and
speaker (if selected). You can check this function by switching from
COM 1 transmitter to Com 2 transmitter by pressing the COM 2 trans-
mitter selector pushbutton. Note that the associated Com 2 receive
pushbutton indicator light that is located immediately above the Com
2 transmitter pushbutton turns green. This guarantees that the pilot
will always hear the , so that when switching transmitters from COM 1
to COM 2, if COM 2 audio was previously selected, COM 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 COM 1 to COM 2 while Com 2 was not previ-
ously selected, COM 1 audio will be switched off. In essence, switch-
ing the mic selector will not override prior selection of COM receiver
audio.
In normal (not split) modes, the PMA8000B gives priority to the pi-
lot’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 con-
tinue. (See Page 4—TEL—for more details)
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 COM 1 and COM 2 XMT
buttons at the same time. This places the
pilot on COM 1 and the copilot on COM 2.
Pilot on COM 2 and Copilot on COM 1 is not
possible.
When the split mode is activated, the intercom between the pilot and
copilot is inhibited, although the passengers can still talk among
themselves.
The crew intercom can be reactivated if desired by pressing the
“Mute” button. The indicator LED in the Mute button will be green
when the intercom is off (muted), and turn off to indicate that the in-
tercom is not muted, and the crew can speak to each other.

Page 4 202-890-0402 PMA8000B Avidyne Pilot Guide
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.
Audio Selector (4)
Navigation receiver audio
is selected through three
momentary, push-button,
backlit switches. You will
always hear the audio
from the selected trans-
ceiver.
The users can identify which receivers are selected by noting which
green switch LEDs are lit. Navigation aid audio push buttons are la-
beled Nav 1, Nav 2, and MKR (Marker). If DME is present, it will be
controlled by the Mon1 button. 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 out-
put.
In SPLIT mode, only the pilot will hear selected navigation audio.
Monitor Function (11)
The MON 1 and Mon 2 buttons allow the pilot to listen to the standby
frequencies selected by the Entegra ACD215 Control/Display Unit.
Monitored audio is muted during transmission to prevent bleed
through.
Note: Split Mode does not turn off Nav, Monitor or ADF selected au-
dio to pilot. However, the copilot will only hear the selected com re-
ceiver and unswitched inputs. MON selection is muted during transmit.

202-890-0402 Rev. 2 Page 5Oct. 2010 PMA8000B Pilot Guide
Telephone (TEL) (9)
The TEL mode serves as a full duplex interface and
distribution for portable cellular phones with ear-
piece 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 tele-
phone. 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 PMA8000B 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 au-
dio is provided to the pilot.
Speaker Amplifier (5)
The SPR in the lower right section stands for
speaker. This switch will place all selected audio
on the cockpit speaker when this switch is se-
lected. Except for the unswitched audio, the
speaker amplifier is not active in the "Split
Mode”.
Unswitched audio 1, 3 and 4 (the inputs dedi-
cated to autopilot disconnect, altimeter warning,
etc.) may come through the speaker regardless of the speaker button
position.
Depending on installation, important audio annunciations such as ra-
dar altimeter or autopilot disconnect will come over the speaker even
Note: As shipped from PS Engineering, the PMA8000B does not provide cellular telephone
sidetone (the user’s voice fed back to the headset). Some cell phones do not provide sidetone.
In PMA8000B Avidyne audio panels serial number X04748 and above, telephone sidetone
can be enabled by pressing the Shift (MON 1) and TEL buttons for more than one second.
Because the cell-phone uses an intercom circuit, all stations on that circuit will lose intercom
capability when the cell phone is in use, unless sidetone is present.

Page 6 202-890-0402 PMA8000B Avidyne Pilot Guide
if it is not selected, while other unswitched, but muted inputs, such as
GPS alerts, will only be present if the SPR button is selected. Consult
your professional avionics installer for these important configuration
details.
Public Address Function
To access PA function, press the Mute
and SPR buttons simultaneously. The
Mute and SPR LEDs will blink to in-
dicate 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 Mute and SPR again.

Oregon Aero MicMuff Part Numbers
Note: For optimum microphone performance, we recommend
use 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.

202-890-0402 Rev. 2 Page 7Oct. 2010 PMA8000B Pilot Guide
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 mo-
ments.
For consistent performance, any headset micro-
phone 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 In-
telliVox® 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 cabin, 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, mu-
sic 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.
Adjust the radios and intercom volume for a comfortable listening
level. Most general aviation headsets today have built-in volume con-
trols; therefore, volume also can be further adjusted at the individual
headset.
Mono Headsets in Stereo Installation
The pilot and copilot positions work with stereo or mono headsets.

Page 8 202-890-0402 PMA8000B Avidyne Pilot Guide
All passenger headsets are connected in parallel. Therefore, if a mon-
aural headset is plugged in to a PMA8000B 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.
Intercom Modes (8)
The “ICS” pushbutton switch
on the left side of the panel pro-
vides the selection of the three
intercom modes. The descrip-
tion of the intercom mode func-
tion 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, ISO, ALL, Crew, ALL, and ISO. An LED shows
the active mode .
ISO:The pilot is isolated from the intercom and is connected only to
the aircraft radio system. He will hear the aircraft radio reception (and
sidetone during radio transmissions).
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 MON 1 button,
and 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 follow the selected modes.
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.
ALL:All parties will hear the aircraft radio and intercom. Crew will
hear Entertainment 1, passengers can hear Entertainment 1 or 2. Dur-
ing any radio or intercom communications, the music volume auto-
matically decreases. The music volume increases gradually back to
the original level after communications have been completed.
CREW: Pilot and copilot are connected on one intercom channel and
have exclusive access to the aircraft radios. Again, the music that the
crew and passengers will hear is determined by the Smart Function
Keys.

202-890-0402 Rev. 2 Page 9Oct. 2010 PMA8000B Pilot Guide
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.
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 cou-
pled 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 select-
ing 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 indi-
cator 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 illumi-
nates 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 re-
ceived will re-activate the audio.
Internal Recorder System
The Intercom Recording System is a digital recording system allow-
ing automatic storage and playback of aircraft radio traffic.
Operating as a continuous loop recorder, (first message received will

Page 10 202-890-0402 PMA8000B Avidyne Pilot Guide
be the last heard), the recorder has 60 seconds of recording time, or
up to 8 messages. With its own built in VOX circuit, there are no but-
tons to press to start recording.
The system automatically begins
to record the instant the radio
becomes active. Only the com
radio selected for transmit is re-
corded, and only the pilot and
copilot will hear the playback
audio.
Operation
Recording is automatic. To play back the last recorded message, press
and hold the COM Receive pushbutton associated with the selected
radio transmitter for about one (1) second. You can either wait for the
message to finish playing before accessing the prior message or can-
cel the playback. To cancel the playback, press and hold the COM
Receive playback button for two seconds (2). The next time the but-
ton is pressed for one (1) second, the next earlier message will be
heard.
The playback will stop whenever there is more incoming selected
com audio, and the message can be replayed from the beginning by
pressing the COM playback button..
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
• Music input
The use of this jack is controlled by three Smart Function Keys (SFK)
controlled from the front panel. See Page 11—Smart Function Keys.
Cellular phone
When a cellular telephone is
connected to this jack using a
2.5 mm to 2.5 mm adapter
cord (PS Part Number 425-
006-7026), the PMA8000B
audio panel will connect the

202-890-0402 Rev. 2 Page 11Oct. 2010 PMA8000B Pilot Guide
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 ad-
visory input for auxil-
iary systems such as a
GPS terrain advisory
or portable traffic
watch system. To pre-
vent radio or intercom from muting this input, press the “Mute” but-
ton.
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 a signal on music #1 input coming in from
the rear connector, the front panel jack automatically becomes a Pri-
ority Advisory input, and is heard in the crew headphones. This input
will NOT be muted by radio or intercom provided that music 1 on the
rear connector has an active audio signal. If this signal is not present,
this input may be muted, unless the Mute is deselected.
Music Input
When used as a music input, the front panel jack is treated as Music
#1. However, thanks to the function controls, it can be distributed to
all users, depending on the intercom mode.
Smart Function Keys (SFK)
With Virtual Tech Support, the configuration process is self-directed.
Once you’ve set up your system, you don’t need to change it again,
unless you want to. The unit will always remember your settings.
Note: VTS annunciations will be stopped by any audio received on
the com radio selected for transmit.
These functions are non-essential and non-required and as such are
only an accessory capability. They don’t affect the audio panel’s pri-

mary function as a selector panel, aircraft intercom, or marker beacon
receiver. You can’t do anything with these buttons to prevent the
PMA8000B from doing its main job.
Looking at the front panel you’ll notice that the Mon 1, Mon 2, Mute
and SPR buttons have “Function” assignments.
To use these function keys A, B, C – press and hold “F” (Mon 1) and
then press the desired key, “A” “B” or “C”.
There are three special functions. Function Button “A” is related to
the intercom function, and allows the crew to mute passengers’ inter-
com feed when radios are active.
Function Buttons “B” and “C” control 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 connec-
tor, only (Pins 26 and 27, J2)
The volume of the audio annunciations and recorder playback can be
adjusted through a hole on the top of the unit marked “ANN VOL.”
Function “A”
Function “A” controls the distribution of aircraft radio within the in-
tercom, as well as passenger intercom muting. In the “standard inter-
com function” mode, aircraft radios are distributed to all, when the
intercom is in the ALL mode. In CREW mode, only the pilot and co-
pilot positions will hear aircraft radios.
When Function A is toggled into “Alternate Intercom Function,” the
passengers will NOT hear aircraft radios, even in the All mode. In
addition, when in the ALL mode, passengers will be able to converse
with the crew. However, when the aircraft radio becomes active, the
intercom audio from the passengers is muted, allowing the crew to
focus on the radio. Passengers will be able to talk to each other.
Function “B”
Function Button “B” allows you to either send the music 1 input to all
intercom stations, all of the time, or have the normal rules apply to
our music inputs.
When “Music number one distribution, all headsets” is selected, mu-
sic 1 (from the unit’s rear connector input) 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, even
though they will not hear the intercom or radios.
This mode allows you to use a single in-flight entertainment source
aboard, and to send it everywhere, even in crew mode. The music
muting will be normal, and follow the selected mode of the crew or
passengers.
When you select Function “B,” for the alternate function, you hear
“Music number one distribution, Crew.” Now, music input 2 will fol-
low the modes in Function “C.”
Function “C”
Function “C” allows you to configure your music to be either inde-
pendent of the intercom mode, or to make Music 2 dependent on the
intercom mode.
When you press Function “C,” you’ll hear, “Alternate Music distribu-
tion.” In this case, Music 2 will be active only when the intercom is in
the CREW mode, and only the passengers will hear it. This distribu-
tion is similar to other brands of audio panels. It allows the passengers
to have their music source come on only when they are not hearing
the crew. In addition, the front panel jack input will be distributed to
the passengers in ALL and ISO mode.
Press again, and you will hear “Standard Music Distribution.” In this
mode, Music 2 becomes active, and will always be presented to the
passengers on the intercom. Music 1 is only available to the pilot and
copilot. The intercom mode switch doesn’t have any affect on the mu-
sic distribution.

When the music is standard, 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 co-
pilot.
This mode is useful if your passengers have a different interest in en-
tertainment or are watching a DVD, but do not want to be excluded
from the intercom conversations.
The pilot can hear this music source in ISO mode, if desired, as fol-
lows: In the ISO mode, hold the Function (Mon 1) button, and press
the ICS mode button for more than one second. The ICS mode LED
will blink slowly to indicate music is connected to the pilot headset,
although the intercom is not.
Music 2 is provided to the passenger positions regardless of intercom
mode, when the audio panel is in Standard Music Distribution, and
also in Alternate Music Distribution, but only if the intercom is in the
CREW mode. The pilot and copilot can never hear Music 2, under
any condition.
If the passengers always want to hear the source in Music 1, input
through the rear connector, regardless of the intercom mode (ISO/
ALL/CRW), select “Music 1 all headsets.”
If the passengers want to hear the music input through the front panel
jack, the audio pane MUST be in Alternate Music Distribution, and
the intercom must be in the ALL or ISO mode.
Music Muting
There are two SoftMute™ muting circuits.
The front panel "Mute" button has four
modes, and controls the Mute function for
music 1.

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 sec-
ond or so.
The mute mode functions are controlled through sequential pushes of
the Mute button, and include annunciations of the mode selected.
Mode 1 - music will mute with either intercom or radio - MUTE but-
ton is lit. Voice annunciation is "mute on."
Mode 2 - “Karaoke” mode - music will not mute except during trans-
missions.- MUTE LED is OFF. Annunciation is "mute off."
Mode 3 - Radio will mute music, but intercom will not mute music -
MUTE LED is OFF. Annunciation is "radio mute."
Mode 4 - Radio will not mute music, intercom will mute music -
MUTE LED is OFF. Annunciation is "intercom mute."
The passenger’s intercom also has a SoftMute™ circuit. If the passen-
gers 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.
Passengers also have a Karaoke Mode. If the passengers are listening
to the music 1 input or front panel input, their Karaoke Mode is con-
trolled by the front panel “Mute” button. If the passengers are listen-
ing to the music 2 input, their Karaoke Mode is activated by an exter-
nal switch installed in the aircraft.
Music 1 Volume
In general, we recommend adjusting the entertainment volume at the
sources, and only using this as a master gain control. However, the
Music 1 volume can be adjusted from the front panel, if desired, by
pressing the combinations of keys listed.

Press Hold Function (Mon 1) and Vol UP (SPR) for more than one
second to increase music 1 volume. If the buttons are held down con-
tinuously, it will increase the volume three steps per second.
Press Hold Function (Mon 1) and Vol Down (Mute) for more than one
second to decrease music 1 or MP3 volume. If the buttons are held
down continuously, it will decrease the volume three steps per second.
The music can be turned completely off, so if you aren’t hearing what
you expect, try increasing the volume as described above.
It will take about 10 seconds to go from minimum to maximum volume.
Warranty & Service
In order for the factory warranty to be valid, the installations in a certi-
fied aircraft must be accomplished by an FAA-(or other ICAO agency)
certified avionics shop and authorized PS Engineering dealer. If the
unit is being installed by a non-certified individual in an experimental
aircraft, a factory-made intercom harness must be used for the warranty
to be valid.
PS Engineering, Inc. warrants this product to be free from defect in ma-
terial and workmanship for a period of three (3) years from the date of
sale. During the first twelve (12) months of the three-year warranty
period, PS Engineering, Inc., at its option, will send a replacement unit
at our expense if the unit should be determined to be defective after
consultation with a factory technician. For the remaining twenty-four
(24) months of the three-year warranty period, PS Engineering will
