DESCRIPTION
The Clear-Com HB-702 and HB-704 headset stations are ideal for use in
theatres, live performances, industrial environments, and small television
facilities. They feature speech intelligibility in all noise levels and can be
customized through their programmable options.
Selectable, multi-channel talking and/or listening allows the operator to
communicate on one of two (HB-702) or four (HB-704) intercom channels.
The dual-action talk button operates in electronic momentary or latching
mode. The HB-702 and HB-704 offer visual call signaling to attract the
attention of operators. The remote mic kill (RMK) feature on main stations
will turn off any open microphones on these headset stations.
The HB-702 and HB-704 stations accept dynamic headsets, such as the
Clear-Com or the HS-6 telephone headset series. A sidetone control allows
the operator to vary the level of his voice as heard in the headset.
The HB-702 and HB-704 receive power from the Clear-Com intercom line.
They mount in a standard two-gang electrical outlet box.
The extra-thick front panel and compact, surface-mount circuitry results in a
smaller-sized and lighter-weight package that maintains Clear-Com
ruggedness. The intercom channels connect to a plug-on screw-terminal strip.
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
