1.3 EQUIPMENT DESCRIPTION
The PMA6000-series is a state of the art audio isolation amplifier and audio selector that contains a voice
activated (VOX) intercom system. It can switch up to three transceivers (Com 1, Com 2 and TEL) and six
receivers (Nav 1, Nav 2, ADF, DME, MKR and AUX). In addition, there are two unswitched inputs, for
telephone ringer and altimeter warning. Push buttons select the receiver audio source provided to the head-
phones. A SPR button allows the user to listen to the receiver(s) selected on the cabin speaker. Except for
the unswitched inputs, all speaker audio is muted during transmit. A rotary switch selects one of the three
transceivers for the pilot and copilot position in transmit. In "Split Mode" the PMA6000 has the ability to
allow the pilot and copilot to operate different transmitters independently and simultaneously.
A fail-safe mode connects the pilot headphone and microphone to COM 1 if power is removed for any
reason, or if the Mic Selector switch is turned to the Off position.
A six-station voice activated (VOX) intercom is included in the PMA6000. pilot isolate and crew modes,
two mono music inputs with "Soft Mute," and a 2-color Light Emitting Diode for power and transmit indi-
cations. Intercom control is through front panel mounted knobs. Monaural units have dual concentric
knobs that control pilot volume and intercom squelch, and copilot/passenger volume and squelch. In the
stereo versions, there is a single volume and squelch control for all on board.
An optional 3-light Marker Beacon receiver is integral to the PMA6000M and PMA6000MC. This pro-
vides the necessary Marker Beacon light and audio indications necessary for an Instrument Landing Sys-
tem (ILS) approach.
