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 Entegra 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.
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 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.
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.
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.
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.
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.
All passenger headsets are connected in parallel. Therefore, if a monaural 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 provides the selection of the three intercom modes.
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 coupled with a 1300 Hertz tone.
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 buttons 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 recorded, and only the pilot and copilot will hear the playback audio. Operation Recording is automatic.
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 Crew GPS terrain advisory or portable traffic watch system. To prevent radio or intercom from muting this input, press the “Mute” button.
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.
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 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 intercom, as well as passenger intercom muting.

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 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.
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 annunciations of the mode selected. Mode 1 - music will mute with either intercom or radio - MUTE button is lit. Voice annunciation is "mute on.
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 continuously, 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.
