PMA8000-SR Audio Control Panel with Integrated
SIRIUS Satellite Radio
Congratulation on your selection of the PS Engineering PMA8000SR Audio Control Panel with integrates SIRIUS Satellite Radio inflight entertainment. This products represents the most completely
integrated audio system ever designed for General Aviation. This
manual provides detailed operating instructions for the PS Engineering PMA8000-SR, Audio Selector Panel/Intercom Systems.
Please read it carefully before using the equipment so that you can
take full advantage of its capabilities.
This publication is divided into four sections covering the basic operating areas of the PMA8000-SR systems. They are Audio Selector,
Intercom, SIRIUS Satellite Radio and Marker Beacon Receiver.
PMA8000-SR 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. This allows communication capability regardless of unit condition . Any time power
is removed or turned
The power switch controls all audio selector panel functions, intercom and
marker beacon receiver.
OFF, the audio selector will revert to fail-safe mode.
Communications Transmit (XMT) Selection (2)
There are two pushbuttons associated with the transmitter selection. The two
lower buttons (item 2) control which transceiver is selected for transmit. The
top row of pushbuttons labeled COM 1 and COM 2 allows selection of the
receiver audio.
Push the lower button to select the desired COM transmitter.

PMA8000-SR Pilot Guide R5
The PMA8000-SR-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 1 transmitter to Com 2 transmit-
ter by pressing the COM 2 transmitter 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 gu arantees that the pilot will
always hear the audio from the transceiver selected for transmit.
The PMA8000-SR “remembers” the receiver selection, so that when switching
transmitters from C
OM 1 to COM 2, if COM 2 audio was previously selected,
COM 1 audio will continue to be heard. This eliminates the pilot from 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 selector
OM 1 to COM 2 while Com 2 was not previously se-
will not override prior selection of COM receiver audio.
In normal (not split) modes, the PMA8000-SR 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,
allowing continued aircraft communications.
The copilot will also be able to transmit on the other selected radio with his PTT
as well.
Split Mode
The split mode is activated at any time by press-
ing the C
OM 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 C
OM 2 and Copilot on COM 1 is not pos-
sible.
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.

Audio Selector (4)
Navigation receiver audio is selected
through five momentary, pushbutton, backlit switches.
The users can identify which receivers are selected by noting which
green switch LEDs are lit. Nav 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 copilo t are connected to the telephone. Pas-
sengers 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-SR is in the TEL mode, the pilot
position is in the "Phone Booth." Only the pilot will hear the telephone, an d 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.

PMA8000-SR Pilot Guide R5
Depending on installation, important audio annunciation s such as rada r altimeter
or autopilot disconnect will come over the speaker even 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
The public address function is not enabled
shipped from the factory. To enable this function,
press the numbers 3, 0, 0 on the SIRIUS remote
controller. The audio panel will then control this
function. Once enabled , to control PA function,
press the Mute and SPR buttons simultaneously. 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 radio while the pilot will now be heard over the speaker.
To exit PA mode, push Mute and SPR again.

Intercom Operation
IntelliVox® VOX-Squelch
No adjustment of the IntelliVox® squelch control is necessary. There is no field
adjustment. Through individual signal processors, the ambient noise appearing
in all 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 lev-
