The Clear-Com KB-112 is a professional single-channel remote speaker station designed to provide a listen-only or talk-back communication point in locations where a full headset station is not required or practical. This compact, surface-mount unit serves as an extension of a wired partyline intercom system, allowing personnel in areas like dressing rooms, green rooms, follow-spot platforms, or workshop areas to monitor production communications. It features a built-in, high-quality speaker for clear audio output and incorporates a rugged, momentary push-to-talk (PTT) button, enabling the remote user to communicate back to the main intercom partyline when pressed. This two-way functionality, activated only during PTT, prevents audio feedback in the remote location.

Constructed with a durable metal or high-impact plastic housing, the KB-112 is built for reliability in permanent installations. Its design includes a volume control knob to adjust the listening level from the partyline and often features a call signal light or button to acknowledge calls from the main system. The station connects to the intercom system via standard 3-pin XLR cables, drawing power and audio from the partyline. The integrated microphone is typically an electret condenser type with noise-canceling properties, ensuring that transmissions are intelligible even in environments with some background noise. The unit is designed for wall mounting, keeping communication accessible yet out of the way.

The KB-112 Speaker Station is an essential tool for expanding the reach of a production intercom system to support personnel and spaces that do not require a dedicated, manned intercom position. It facilitates crucial one-way information flow (constant listen) with the capability for controlled two-way interaction (talk via PTT), enhancing overall situational awareness and coordination. By providing a simple, robust, and cost-effective remote interface, it ensures that key off-stage areas remain connected to the live communication network, contributing to smoother operations and quicker response times during events, broadcasts, and theatrical performances.
