Clear-Com RM702
Remote Intercom Station, 2 Channel

RM702

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 head-set, 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 intelligibility 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.
