Clear-Com RM702 Data Sheet
The RM-702 is one of a series of professional remote intercom stations.
The remote speaker/headset station allows two-channel selectable talk
and listen in one rack space. The operator can talk and listen on either
channel separately or talk to both channels simultaneously without tying
the two channels together. Specially contoured audio response provides
excellent speech intelligibility, even in high-noise environments.
The RM-702 can monitor intercom activity on one or both channels with
individual Listen Level controls. Monitor intercom activity through a headset, the internal speaker, or both at once. The 4-watt output amplifier can
drive the wide-response speaker or Clear-Com headset to very high output levels - more than enough volume for the noisiest environment.
A “speaker dipping” circuit helps to reduce feedback when stations are
placed in close proximity to each other.
The station has a convenient speaker “on/off” switch when private
conversation via the headset is desired. The station accepts dynamic
headsets or optional plug-in gooseneck mic.
Talk Selection
The operator can talk on either of the channels separately or on both at
once. A proprietary contoured frequency response in the mic pre-amp
enhances speech intelligibity in high-noise environments. Illuminated
dual-action talk buttons are electronic momentary or latching; blue-color
LED while in stand-by, and amber-color LED when latched. The latching
feature may be disabled if desired. The station also features a headset
or microphone selector switch. The talk buttons can also be remote
controlled with a footswitch.
Signaling
The RM- 702 features individual call buttons and visual call signaling to
attract the attention of operators who have removed their headsets or
turned off their speakers. The visual signaling flashes the illuminated talk
button when a call is received. The call-signaling feature can be
programmed to the talk buttons.
AUX. Audio Input and Program Interrupt (IFB)
The station can accept either a balanced or unbalanced line-level audio
input through the DB-15 connector on the rear panel. The program can be
monitored at the station or fed into channel B, where it can also be set up
for IFB/Program interrupt from this or any other Encore station.

Additional Features
Each channel has its own sidetone control.
This allows the operator to vary the level of their
own voice as heard in the headset. When the
announce button is pressed, the microphone
signal is routed to a connector on the back panel.
Relay contacts are also available for muting
speakers or turning on a signal light. The station
accepts Clear-Com’s 9” or 18” gooseneck
microphone.
