3-pin XLR connectors are provided on the four-gang V-box for an inline
connection to one of the intercom channels.
The optional EB7-TW daughter board module can be installed to provide an
interface to two intercom channels on a single microphone cable. Also, the
EB7-4W four-wire daughter board module is available to allow long-distance
connections using separate pairs of wire for send audio and receive audio. The
EB7-4W four-wire option supports two-channel operation.
The KB-702 and KB-702GM are compatible with all Clear-Com party-line
intercoms.
OPERATION
Normal operation of the KB-702 speaker station requires access only to the
front panel controls. The controls located elsewhere on the unit are intended
to be set-and-forget in nature. For intercom operation, set the listen level
control to the desired level and press the talk button when talking. If a headset
or handset is used, set the sidetone control for each channel for the desired
amount of sidetone in the earphone. If a hand-held push-to-talk mic is used, or
if the panel mic is used on the KB-702GM, set the sidetone controls for
minimum feed-through to the speaker to prevent acoustic feedback.
