Entertainment muting

The PMA8000C-system incorporates a four-mode "Soft Mute™" system. This will mute the entertainment
devices during ICS and/or radio conversation. See
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 ra-
dios in the foreground and eliminates the constant interruption of the music while still keeping the radios a
priority.
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
entertainment devices.
All additional entertainment devices must be switched off for both takeoff and landing.
2.5.2.1 Entertainment 2 Mute
Pressing the AUX & MUTE for more than 1 second will activate the Karaoke mode for the Music #2, pas-
sengers' music.
2.5.3 Configuring Music Input with Function Keys
The music inputs can be configured by the user from the front panel (see
configurations available, independent (standard music distribution), ICS mode dependent (alternate music
distribution), 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 pas-
senger 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
As delivered from PS Engineering., both 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,
please contact PS Engineering for more information.
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 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 PMA8000C, and ground. When installed, this button will act as in § 3.12.
