F (FRONT): The input signal source is the microphone connected to the
MIC IN connector.
R (REAR): The input signal source is the audio equipment connected to
the AUDIO IN CH-1/CH-2 connectors.
W (WIRELESS): The input signal source is a WRR-855A/855B UHF
Synthesized Tuner Unit (not supplied).
Note
These switches are not activated when you use the camcorder for the first
time after purchase because the camcorder has been set at the factory so
that the input signals to be recorded to audio channels 3 and 4 are the
same as the ones input to the AUDIO IN CH-1/CH-2 connectors.
To activate these switches, change the setting of the AUDIO CH3/4
MODE item from CH1/2 to SW on the VTR MODE 1 page of the
MAINTENANCE menu.
With a CA-701 (not supplied) connected to the camcorder, you can
record separate sounds on audio channels 3 and 4.
7 AUDIO OUT (audio output) connector (XLR type, 5-pin, male)
This connector outputs the audio signals recorded to audio channels 1
and 2 or audio channels 3 and 4.
The MONITOR CH-1/2 / CH-3/4 switches qs allow you to select the
audio signal to be monitored.
Using a CCXA-53 Audio Cable (not supplied), you can convert from a 5-pin
connection to two 3-pin connections.
