The passenger’s 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 a f-
fect 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 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 panel, or
connected to the AUX button logic output pin on the PMA8000B MP3.
3.8.1 Music in Pilot ISO mode
[Units above serial number E10251 only] If desired, the pilot can elect to hear Music #1, I the ISO mode.
While the intercom is in ISO mode, push the Function (TEL) and ICS buttons at the same time. This
mode will be indicated by the ICS ISO LED blinking slowly (once in every 5 seconds). The pilot will now
hear Music #1, and it will mute in accordance with the Mute mode as d escribed in §3.8.
3.9 Telephone Mode (9)
The TEL mode serves as a full duplex interface for telephone systems such as AirCell or portable cellular
phones with earpiece jacks. When interfaced with an approved airborne telecommunications system, the
PMA8000B-MP3 can serve as a audio control and distribution center. When TEL is active, the button will
blink about twice as fast as the normal transmit rate.
In ALL intercom mode, all crew and passengers will be heard on the phone when they speak. All will
hear selected audio. Com audio is automatically heard in the headsets.
In CREW mode, the pilot and copilot are connected to the telephone. The pil ot and copilot will have
transmit capability on the other selected transceiver Com 1 or 2, simply by using their respe ctive PTT
switch.
In ISO intercom mode, when the PMA8000B-MP3 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 a ccess to Com
1 or 2, and will transmit on that radio using the PTT. All selected audio is provided.
As shipped from PS Engineering, the PMA8000B-MP3 does not provide cellular telephone sidetone (the
user’s voice fed back to the headset), because this is often provided by the telephone itself.
Some cell phones do not provide sidetone. In PMA8000B MP3 Avidyne audio panels above serial number
D10251, telephone sidetone can be enabled by pressing the TEL and ADF buttons for more than one sec-
ond. For units with serial number D10250 and below, an internal modification can be made that will a l-
low the PMA8000B-MP3 to provide this sidetone. Contact PS Engineering for more information.
NOTE
Because the cell phone uses an intercom circuit, all stations on that circuit will lose intercom capabi lity
when the cell phone is in use, unless the cellular phone provides it’s own sidetone.
PS Engineering does not guarantee compatibility with personal cellular telephones.
