2.2 Description
The Clear-Com KB-702 is a two-channel speaker station ideal for theatre, live
performances, industrial applications, and small TV facilities. It features excellent
speech intelligibility even in high-noise environments and can be tailored to your
needs through its programmable options.
In addition, the Clear-Com KB-702GM/KB-802GM-IM contains a jack for an optional
Clear-Com gooseneck panel microphone and a close-in, voice-controlled circuit
(VOX). This circuit allows automatic, alternate dipping of the panel microphone and
the speaker in response to conversation.
Selectable two-channel talking and/or listening allows the operator to
communicate on either of the intercom channels. The dual-action talk button is
electronic momentary or latching. Monitoring can be done through the headset, the
integral speaker, or both at once. The KB-702 offers both visual and audible call
signaling to attract the attention of operators. The remote mic kill (RMK) feature on
main stations will turn off any open mics on the KB-702.
A balanced program input allows the monitoring of external audio using the headset
or speaker. This program input can also be used as a paging function.
The KB-702 speaker station accepts dynamic headsets. A sidetone control allows
the operator to vary the level of his/her own voice as heard in the headset and
speaker.
The integral speaker can be turned on or off by a convenient front panel switch. An
automatic speaker dipping circuit will lower the level of the speaker whenever the
talk button is activated. This feature helps minimize acoustical feedback.
The KB-702 receives power from the Clear-Com intercom line. The unit mounts
either in a standard four-gang electrical outlet box or in an optional Clear-Com four-
gang V-box. The extra-thick front panel and compact surface-mount circuitry
