engineering.com to obtain a wire harness work sheet. The harness will be made to your specifications and
fully functionally tested. Harness can be ordered with jack, or without the intercom jacks installed, for easi-
er wire routing through the aircraft.

2.5.2 Entertainment muting
The PMA8000BT-system incorporates a four-mode "Soft Mute™" system. This will mute the entertainment
devices during ICS and/or radio conversation. See
Section 3.8 for more information.
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 (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.
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). Then, Entertainment 2 will not mute when the AUX button is on.
(Not recommended if DME is input is used.)
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, ICS mode dependent, 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
