Split Mode
Turning the rotary switch to C OM 1/2 puts the 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 and
do not have intercom capability, 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
OM 2/C OM l. The pilot will be on Com 2 and the copilot
will be on Com 1.
Turning the mic selector clockwise to the C OM 3 position
places both pilot and copilot on Com 3, and exits the split
mode. All selected audio inputs and intercom function return.
N o t e :
Due to the nature of VHF communications signals, and the size
constraints in general aviation aircraft, it is probable that there
will be some transmission bleed-over in the Split mode, particu-
larly on adjacent frequencies.
PS Engineering makes no warranty about the suitability of Split
Mode in all aircraft conditions.
Note:
In all PMA6000-series, Split Mode turns off all other (Nav,
ADF, etc.) selected audio to pilot and copilot. Additionally,
there is no intercom function between pilot and copilot. Pas-
sengers still have intercom capability among themselves.
Intercom Operation
Volume Control
The pilot volume control knob
adjusts the loudness of intercom
and music in the pilot’s head-
phones only. It has no effect on
selected radio audio levels. The
