one intercom channel and have exclusive access to the aircraft
radios. They may also listen to Entertainment 1. Passengers
can continue to communicate with themselves without inter-
rupting the Crew and also may listen to Entertainment 2. Any-
time the PMA6000 is in either the C
1, or T /C 1, ("Split Mode") the pilot and copilot do not

have any intercom function. The passengers will maintain in-
tercommunications.
Soft Mute
Soft Mute must be enabled during installation by jumpering
top connector pins 12 and N. A SPST switch can be installed
between these pins for a pilot selectable mute mode. Without
this connection, music is not muted during intercom activation.
This "Karaoke Mode" prevents the music muting when a sing-
a-long is desired. "Soft Mute" mode only applies to entertain-
ment input #1. Entertainment #2 does not mute.

Entertainment Input

The audio selector panel has provisions for up to two separate
entertainment input devices. Which device is heard is deter-
mined by the position of the 3-position mode switch located in
the center of the intercom section of the audio panel. (See Ta-
ble 1 for overview.)
While in the ISO (Isolate) mode, only the copilot and the four
passengers will hear entertainment device #1. In normal opera-
tion, whenever a person speaks, the music will automatically
mute and then will gradually return to the original listening
level when the radio or intercom activity ceases.
When in the A mode, all parties will hear the entertainment

Swap Mode (Switch from Com 1 to Com 2 remotely)
With a yoke mounted, momentary switch, the pilot can change
from the current Com transceiver to the other by depressing
this switch. When "Swap Mode" is active, an LED annunciator
will illuminate, indicating that the Mic Selector switch position
is no longer valid. To cancel "Swap Mode," the pilot may ei-
ther press the yoke mounted switch again, or turn the Mic Se-
lector Switch to the Com that is active.
Split Mode (6000, 6000M)
Turning the rotary switch to C
PMA6000 into "Split Mode". This places the pilot on Com 1
and the copilot on Com 2. Pilot and copilot are isolated from
each other on the intercom, but can use their respective radios
simultaneously. An example of this useful feature is when the
pilot may want to talk to Air Traffic Control, while the copilot
may be speaking to Flight Watch.
The "Split Mode" radio selection can be reversed by switching
to C 2/C l. The pilot will be on Com 2 and the copilot
OM OM
will be on Com 1. A third "Split Mode" selection is T
l. This will place the pilot on airborne radiotelephone, HF or
other transceiver (if installed), while the copilot will be on
Com 1.
Split Mode (6000C, 6000MC)
Operation is identical to the 6000, 6000M (above) except turn-
ing the mic selector clockwise to the C
both pilot and copilot on Com 3, and exits the split mode. All
selected audio inputs and intercom function return.
Note: In all PMA6000-series, Split Mode turns off all
other (Nav, ADF, etc.)selected audio to pilot and copi-
lot. Additionally, there is no intercom function between
pilot and copilot. Passengers still have intercom capabil-
ity among themselves.
