The Clear-Com KB-702GM is a professional dual-channel remote speaker station designed for Clear-Com partyline intercom systems where convenient, hands-free communication is essential. With support for two intercom channels, an integrated speaker, headset connectivity, and a dedicated gooseneck microphone input with VOX circuitry, the KB-702GM provides operators with several ways to communicate and monitor production activity.
The KB-702GM is particularly well suited for theaters, broadcast facilities, live event venues, production rooms, houses of worship, and other environments where a permanently installed communication station is preferred over a beltpack.
Gooseneck Microphone and VOX Operation
One of the defining features of the KB-702GM is its panel microphone input for an electret gooseneck microphone. The integrated VOX circuitry provides voice-activated operation, making the station convenient for users who need to communicate without continuously holding a push-to-talk button.
The station can also accommodate different communication methods depending on the installation, including:
- Gooseneck microphone
- Headset microphone
- Telephone-style handset
- Push-to-talk microphone
- Built-in speaker for monitoring
This flexibility allows the KB-702GM to serve a variety of production positions and communication workflows.
Two-Channel Partyline Communication
The KB-702GM provides access to two partyline channels, allowing operators to select the appropriate communication path directly from the station. The built-in speaker provides convenient monitoring, while a connected headset can be used when greater audio isolation is required.
Four programmable operating modes can be configured using the internal DIP switches, allowing system designers to tailor the station's operation to the requirements of the installation.
Designed for Fixed and Portable Installations
The KB-702GM can be installed in a wall or console, or used with an optional V-Box for portable and desktop applications. This makes it suitable for both permanent production facilities and temporary event setups.
A balanced local program input with independent level control allows program audio to be incorporated into the station, while visual and audible call signaling helps operators recognize incoming communication requests.
For systems requiring additional audio connectivity, an optional 4-wire daughter board can expand the station's integration capabilities.
