AUDIO CONTROL PANELS
SECTION 1
GENERAL
Two types of audio control panels (see figure 1) are available for this
airplane, depending upon how many transmitters are included. The
operational features of both audio control panels are similar and are
discussed in the following paragraphs.
TRANSMITTER SELECTOR SWITCH
When the avionics package includes a maximum of two transmitters, a
two-position toggle-type switch, labeled XMTR, is provided to switch the
microphone to the transmitter the pilot desires to use.
If
the airplane
avionics package includes a third transmitter, the transmitter selector
switch is a three-position rotary-type switch, labeled XMTR SEL. To select
a transmitter, place the transmitter selector switch in the position number
corresponding to the desired transmitter.
The action of selecting a particular transmitter using the transmitter
selector switch simultaneously selects the audio amplifier associated with
that transmitter to provide speaker audio. For example, if the number one
transmitter is selected, the audio amplifier in the number one NAV / COM
is also selected and is used for ALL speaker audio. Headset audio is not
affected by audio amplifier operation.
AUDIO SELECTOR SWITCHES
Both audio control panels (see figure
1)
incorporate three-position
toggle-type audio selector switches for individual control of the audio
systems installed in the airplane. These switches allow receiver audio to
be directed to the airplane speaker or to a headset, and heard singly or in
combination with other receivers. To hear a particular receiver on the
airplane speaker, place that receiver's audio selector switch in the up
(SPEAKER) position. To listen to a receiver over a headset, place that
receiver's audio selector switch in the down (PHONE) position. The center
(OFF) position turns off all audio from the associated receiver.
NOTE
Volume level is adjusted using the individual receiver
volume controls on each radio.
