KB-702/KB-702GM TWO-CHANNEL SPEAKER STATIONS

1-2

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.
