2.4.18Entertainment muting

The PMA8000-SR-system incorporates a "Soft Mute" system. This will mute the entertainment devices during ICS or radio conversation.

Any signal appearing in the unswitched audio inputs will always mute the entertainment sources, even though the passengers may not hear the audio tone itself.

Press the Mute switch to activate the Karaoke mode (disabling crew SoftMute™), This allows the pilot to place the entertainment into the background while having the radios in the foreground. This eliminates the constant interruption of the music while still having the radios a priority.

Caution: Local oscillators and internal signals from entertainment equipment can cause undesired interfer- ence 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.

2.4.18.1.1 Entertainment 2 Mute (J2 Pin 13 & 14)

Connecting J2 pin 13 to pin 14 (or ground) through a SPST switch places the entertainment #2 music source into the Karaoke Mode. In this mode, incoming music and intercom conversation will not mute the music for the passengers’ intercom net. This allows uninterrupted music during casual conversation and at times when radio communications are of lesser importance.

See section 2.4.14 for alternative music connection to allow the passengers and crew to use the same input.

If desired, the AUX button can act as the passengers’ mute control. Connect J2 pin 18 (AUX logic) to J2 pin 13 (Entertainment. 2 Mute inhibit). This is NOT recommended is AUX is also used as an audio switch.
