PMA6000B Audio Selector Panel and Intercom System

Installation Manual

200-066-0200 Page 2-4 Rev 6, Feb. 2013

The “Mute” button can be used to inhibit the soft mute function, keeping music at the same level. In

CREW mode, passengers will hear Music #2, and this will also be controlled by the “Mute” button located

on the front panel.

Entertainment inputs #1 and #2 can be paralleled so a single entertainment source can serve both the pas-

sengers and the crew in "crew" mode. It is suggested however, that a switch (DPDT) is installed between

the single entertainment device and entertainment input #1. This will allow the pilot and copilot to decide

if they hear entertainment while in the Crew mode.

Local oscillators and internal signals from some 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.
