a. Listen is factory set to be ON all the time on both
channels. Setting W1 to the OFF position will dis-
able intercom listen audio on channel 1 (usually
the left headphone of a stereo headset). Setting W2
to the OFF position will disable intercom listen
audio on channel 2 (usually the right headphone of
a stereo headset). Listen disable could be used, for
example, when you want to use the left side of a
stereo headphone exclusively for program audio
input and the right side for a single channel of
intercom audio. In this case you would:
1. Set W1 to OFF to disable channel 1 intercom
audio listen to the left headphone.
2. Set DIP switch 4 to ON to disable channel 1
talk.
3. Setup the left channel for program input.

headphone, right headphone or both headphones.
If you are using a mono headset, set both W3 and
W4 to ON.

c c. W5 applies to a stereo dynamic-mic headset con-
nected to the STEREO HEADSET jack. With W5
set in the stereo position, intercom channel 1 will
be heard in the left headphone only, and channel 2
will be heard only in the right. In the mono posi-
tion, both intercom channels (and program audio if
connected) will be heard in both headphones. If
you are using monaural headphones connected to
the MONO HEADSET jack, W5 may be left in the
stereo position.

d. The CARB-MIC connector may be used to con-
nect either a headset or an external mic ON/OFF
switch. (If you are using a carbon-mic headset, but
still wish to use an external mic switch, the LINE
LOOP connector may alternatively be used for the
mic switch. See note X, below.) To use the CARB-
MIC connector for an external mic ON/OFF
switch:
1. Place jumper W7 in the “EXT MIC SW” posi-
tion.
2. Use a stereo phone plug to connect the external
switch to the CARB-MIC HEADSET jack:
