Installation and Operator’s Manual

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
Pressing the AUX & MUTE for more than 1 second will activate the Karaoke mode for the Music #2, pas-
sengers’ music.
2.5.3 Configuring Music Input with Function Keys
The music inputs can be configured by the user from the front panel (see Section 3.10.3 ). There are three
configurations available, independent (standard music distribution), ICS mode dependent (alternate music
distribution), 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 (Soft-
Mute™) 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
is ONLY active in CREW mode, and then provided only to the passengers. The externally switched passen-
ger SoftMute™ control becomes active in CREW.
If the single-source mode is activated through the function keys, the front panel jack (and music 1) is con-
nected to all intercom positions, regardless of the intercom mode. Crew muting is controlled by the front
panel, passenger muting controlled through the switch. See section 3.11 for more details.
2.5.3.1 Annunciation and recorder playback
As delivered from PS Engineering., both the pilot and copilot can hear the Function Key annunciations. If
the customer wants to exclude playback and function key annunciation playback from the copilot position,
please contact PS Engineering for more information.
2.5.4 Playback Button Installation
Internal Recorder can be played back from the front panel. A remote momentary, normally open (NO) push
button switch may be installed if desired to remotely activate the Recording System playback. This switch
can be located anywhere in cockpit convenient to the pilot's reach. The NO switch should be connected to
pin 22 of J2 of the PMA8000C, and ground. When installed, this button will act as in § 3.12.
2.5.5 Passenger Intercom Expansion (050-890-0313 only)
The PMA8000C (-0313) can support up to two, six-place intercom expansion units (PS Part Number
11636R), for up to 12 passengers.
In the installation with expansion, the passengers can speak to each other at all times, and the intercom
mode control allows for intercom communications with the copilot or both crew members. Operation is
identical to the standard PMA8000C.
2.6 Marker Beacon Installation
2.6.1 Marker Antenna Installation
A marker beacon antenna, appropriate to the type and speed of the aircraft, is required (not included). Refer
to aircraft and antenna manufacturer's installation instructions, as well as AC43.13-2B (or later revision),
Chapter 3, for information on proper antenna installation techniques. The marker beacon antenna must be
mounted on the bottom of the aircraft.
