all and crew modes, two independent stereo music inputs with "SoftMute™". Intercom volume control is
through two concentric front panel knobs and a pushbutton intercom mode switch. The small volume knob
controls the intercom level for the pilot and copilot, while the large knob controls the passenger intercom
volume. Intercom squelch is automatic.
The PMA8000C P/N 050-890-0303 has a 6-place intercom, while the 050-890-0313 can support two ex-
pansion units for up to a 14 place intercom (2 crew +12 passenger positions).
A 3-light, 75 MHz Marker Beacon receiver is integrated in the PMA8000C. This provides the necessary
Marker Beacon lights and audio indications necessary for that portion of an Instrument Landing System
(ILS) approach. A pushbutton labeled MKR allows the pilot select the receiver audio as well as test and
mute modes.
In the PMA8000C, a Bluetooth® wireless interface is available for wireless telephone and music connec-
tion.
