2.7.1.1 Music 1 all headsets (J2, Pin 22)

If J2, Pin 22 is connected to aircraft ground, Music 1 will also be heard in the passengers’ headsets. Music

2 will be disabled when J2, Pin 22 is grounded.

2.7.2 Music muting

The PAR200-system incorporates a "Soft Mute™" system. This will mute the music devices during inter-

com conversation or radio reception. The four muting modes are controlled by the front panel “Mute”

button. See §3.9 for more information.

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 ad-

verse effect within the aircraft systems. If any unusual operation is noted in flight, immediately switch off

the entertainment devices.

All entertainment devices must be switched off for both takeoff and landing.

2.7.2.1 Music 2 Mute (J2 Pin 13 & 14)

Connecting J2 pin 13 to pin 14 (or ground) through a SPST switch places the music #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.
