2.7.2.1
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.
2.7.3
Music muting
The PAR200A incorporates a "Soft Mute™" system. This will mute the music devices during intercom con-
versation 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 adverse
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.
2.7.3.1
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.
2.8 Adjustments
The PAR200A is factory adjusted to accommodate the typical requirements for most aircraft configurations.
There are three adjustments with access holes through the top cover (see §
2.11
) that allow the installer to
tailor the specific functions.
Unswitched Input 3 Volume, adjust from 50% to 200% of input value. Turn

TEL VOL- The received telephone volume. The unit is set at the factory for 75% of volume. Turn
Clockwise
to increase the TEL receive volume.
LCD CST: adjusts display contrast to suit individual preferences and ambient light.
DIP Switches (Mic gain and phone sidetone) – PS Engineering installers should call for the Service
Aid.
