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, Inter­com, 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
The power switch controls all audio selector panel functions, inter­com and marker beacon receiver. All pushbutton selections will be
remembered and return to the last state when turned on.

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 (# 2) control which transceiver is selected for
transmit. The top row of pushbuttons (# 3) allows selection of the re­ceiver audio. Push the lower button to select the desired COM trans­mitter.

The PMA8000B-Series has an automatic selector system. 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 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 C
to C

OM 2, if COM 2 audio was previously selected, COM 1 audio will

OM 1

continue to be heard. This eliminates the pilot having to switch Com 1
audio back on, after changing transmitters.

When switching from C
ously selected, C

OM 1 audio will be switched off. In essence, switch-

OM 1 to COM 2 while Com 2 was not previ-

ing the mic selector will not override prior selection of COM receiver
audio.

In normal (not split) modes, the PMA8000B 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. (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 C
buttons at the same time. This places the
pilot on C

Pilot on C

OM 1 and the copilot on COM 2.

OM 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 in­tercom is not muted, and the crew can speak to each other.

Note: Split Mode does not turn off Nav, Monitor or ADF selected au­dio to pilot. However, the copilot will only hear the selected com re­ceiver and unswitched inputs. MON selection is muted during transmit.

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
from the selected trans­ceiver.

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, 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 out­put.

In SPLIT mode, only the pilot will hear selected navigation audio.

hear the 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.

Telephone (TEL) (9)

The TEL mode serves as a full duplex interface and
distribution for 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 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 au­dio is provided to the pilot.

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.

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 se­lected. Except for the unswitched audio, the
speaker amplifier is not active in the "Split
Mode”.

Unswitched audio 1, 3 and 4 (the inputs dedi­cated 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 ra­dar altimeter or autopilot disconnect will come over the speaker even

202-890-0402 Rev. 2 Page 5 Oct. 2010 PMA8000B 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 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.
