Clear-Com KB702

 The KB-702 remote speaker station provides two channel of party-line communications, with the ability to talk and/or listen on the selected channel. The user can listen via the integral speaker, or may use a headset or telephone-style handset – and can talk via a headset mic, a telephone handset, or a push-to-talk microphone. Two-channel-selectable, full-duplex speaker station mounts in a U.S.-standard 4-gang electrical box for wall, console, or portable use. The microprocessor-controlled station features visual and audible call signaling, momentary/latching talk button, balanced program input, and standard or 4-wire and TW connection with optional daughter board.
