The RM-120A is a remote speaker station that allows selectable communicating in the Clear-Com System. The operator can talk and listen on Channel A, Channel B, or both at once (without tying them together).

The RM-120A mounts in a 19" rack, using just 1.75" vertical space. It features a wide frequency response speaker and operates with a carbon headset or a dynamic headset/telephone-style handset.

The rear panel provides a 1/4" jack for output to an external speaker (using it disconnects the internal speaker). The operator can turn down the volume of the built-in or external speaker to have a private conversation with a headset. Alternately, the gooseneck or headset mic can be turned off to use the RM-120A for "listen-only" (paging.)

The RM-120A provides a balanced program input for monitoring external audio in the speaker or headset. The RM-120A mixes the program with the intercom signal for monitoring in the headset and/or speaker. The station provides separate controls for adjusting intercom and program volume levels.

The "Stage Announce" feature is for paging applications. The RM-120A provides a balanced, line-level output signal to a 1/4" phone jack (on the rear panel.) The Stage Announce button on the front panel activates this output, giving the operator access to an external speaker/amp system. Pressing Stage Announce mutes the operator's voice to the intercom channels.

Visual Signaling is a standard Clear-Com feature. The "Call" button attracts the attention of intercom users who have removed their headsets or turned off their speakers (it can also activate remote control of KB-112 Stations). The RM-120A provides a Call button to signal stations on the channel(s) chosen with the "Channel Select" toggle switch. Each channel has a lamp to indicate incoming signals, regardless of the Channel Select switch position.
