Press the Mute switch to activate the four Karaoke modes (disabling crew SoftMute™). Turning down the
entertainment volume allows the pilot to place the entertainment into the background while having the radi-
os in the foreground and eliminates the constant interruption of the music while still keeping the radios a
priority.
CAUTION
Local oscillators and internal signals from entertainment equipment can cause undesired interference with
other aircraft systems. Before takeoff, operate the entertainment devices to determine if there is any adverse
effect within the aircraft systems. If any unusual operation is noted in flight, immediately switch off the en-
tertainment devices.
All additional entertainment devices must be switched off for both takeoff and landing.
2.5.2.1 Entertainment 2 Mute
In the copilot panel, if Music input 2 is used to feed music to the expansion unit, Music 2 mute control is by
holding the AUX and MUTE buttons for more then one second. This is functional for the copilot audio
panel only.
2.5.3 Configuring Music Input with Function Keys
The music inputs can be configured by the user from the front panel (see section 3.10). There are three con-
figurations available, independent (standard music distribution), ICS mode dependent (alternate music dis-
tribution), and single input (music 1 to all stations).
If the inputs are independent, Input #1 (or the front jack) is provided to the pilot and copilot. Muting
(SoftMute™) is controlled by the front panel “mute” button. Music 2 is provided to the passengers at all
times, with muting controlled by an external switch (see § 2.5.2.1).
If the inputs are intercom mode dependent, input 1 goes to the pilot, copilot, and all passengers when the
intercom is in the “ALL” mode. In “ISO” mode, the copilot and passengers will hear music input 1. Music 2
is ONLY active in CREW mode, and then provided only to the passengers. The externally switched passen-
ger SoftMute™ control becomes active in CREW.
If the single-source mode is activated through the function keys, the front panel jack (and music 1) is con-
nected to all intercom positions, regardless of the intercom mode. Crew muting is controlled by the front
panel, passenger muting controlled through the switch. See section 3.11 for more details.
2.5.3.1 Annunciation and recorder playback
The pilot and copilot can hear the Function Key annunciations. If the customer wants to exclude playback
and function key annunciation playback from the copilot position, contact PS Engineering for more infor-
mation.
2.5.4 Playback Button Installation
Internal Recorder can be played back from the front panel. A remote momentary, normally open (NO) push
button switch may be installed if desired. This will allow you to remotely activate the Recording System
playback. This switch can be located anywhere in cockpit convenient to the pilot's reach. The NO switch
should be connected to pin 22 of J2 of the PMA8000D, and ground. When installed, this button will act as
in § 3.13.
2.5.5 Passenger Intercom Expansion (IntelliPAX)
The PMA8000D can support one or two, six-place intercom expansion units (PS Part Number 11636R), for
up to 12 passengers. These expansion units are connected to the copilot’s PMA8000D.
In the dual installation with expansion, the passengers can speak to each other at all times, and the intercom
mode control allows for intercom communications with the copilot or both crew members. See section
3.7.3. for operating information.
