2.1 Introduction

Congratulations and thank you for choosing this Clear-Com product. The KB-702
and KB-702GM/KB-802GM-IM two-channel speaker stations are powerful, user­friendly units that can serve as versatile intercom stations.

Please read this manual completely to better understand the functions of these
products. For questions not addressed in this manual, contact the dealer or Clear­Com directly. Clear-Com applications support and service people are ready to help.

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.

User Guide| KB-702/KB-702GM/KB-802-GM-IM

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 four­gang V-box. The extra-thick front panel and compact surface-mount circuitry

maintains legendary Clear-Com ruggedness. The two intercom channels connect to

a plug-on screw terminal strip. Male and female 3-pin XLR connectors are provided
on the four-gang V-box for an inline connection to one of the intercom channels.

The KB-702 and KB-702GM/KB-802GM-IM are compatible with all Clear-Com party­line intercoms.

2.3 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 set­and-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/KB-802GM-IM, set the sidetone controls for minimum feed­through to the speaker to prevent acoustic feedback.
