The outer knob (♫) controls the volume of the Music 1 input (and Bluetooth music). It has no effect on the
radio, intercom, telephone, or Music 2 input for the passengers.
Adjust the radios and intercom volume for a comfortable listening level. Most general aviation headsets
today have built-in volume controls; therefore, volume also can be further adjusted at the individual head-
set.
3.3 Communications Transmit (XMT) Selection (2)
The two buttons C1 and C2 (# 2) in the XMT section control which com-
munications radio is selected for transmit. The top row of pushbuttons (#
3) allows selection of the receiver audio. Push the lower button to select
the desired COM transmitter. A green LED above the button illuminates
to indicate that the audio is selected.
The PAR200-Series has an automatic com receiver selector system. Audio
from the selected transceiver is automatically heard in the headsets and
speaker (if selected). You can check this function by switching from Com
1 transmitter to Com 2 transmitter by pressing the C
OM 2 transmitter se-
lector pushbutton. See that the associated Com 2 receive pushbutton indi-
cator light that is located immediately above the Com 2 transmitter
pushbutton turns green. This guarantees that the pilot will always hear the audio from the transceiver se-
lected for transmit.
The PAR200 “remembers” the receiver selection, so that when switching transmitters from C OM 1 to C OM
2, if C OM 2 audio was previously selected, C OM 1 audio will continue to be heard. This eliminates the pilot
having to switch Com 1 audio back on, after changing transmitters.
When switching from C OM 1 to C OM 2 while Com 2 was not previously selected, C OM 1 audio will be
switched off. In essence, switching the mic selector will not override prior selection of COM receiver au-
dio.
3.3.1.1 Split Mode
The split mode can be activated at any time by pressing the C1 and C2 XMT buttons at the same time.
This places the pilot on C OM 1 and the Copilot on C OM 2.
Pilot on C OM 2 and Copilot on C OM 1 is not possible.
NO 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 bleed-over in the Split mode, particularly on adjacent frequencies. PS
Engineering makes no warranty about the suitability of Split Mode in all aircraft conditions.
3.3.1.2 Swap Mode (Switch from Com 1 to Com 2 remotely)
With a yoke mounted, normally open momentary switch, the pilot can change from the current Com
transceiver to the other by depressing this switch. To cancel "Swap Mode," the pilot may either press the
yoke mounted switch again, or select a different Com with the XMT buttons.
3.4 COM Audio Selector (3)
Communication audio from the other radio, not selected for transmit, can be heard by pressing the associ-
ated RCV button. You will always hear the audio from the selected transceiver.
In SPLIT mode, only the pilot will hear selected navigation audio (N1 & N2).
3.5 Navaid Audio selection (4)
VHF Navigation receiver audio is selected through two momentary, push-button, backlit switches.
The users can identify which receivers are selected by noting which green LEDs are lit above the button.
Navigation aid audio push buttons are labeled N1 & N2.
