The Clear-Com KB-702 is a dual-channel remote speaker station built for professional partyline intercom systems where operators need convenient access to two communication channels from a single wall- or console-mounted station. Users can select between channels and communicate using a headset, handset, or the station's integrated speaker and microphone.
Designed for theaters, broadcast facilities, live event production, houses of worship, and other professional communication environments, the KB-702 provides straightforward intercom control without requiring a separate beltpack. Its built-in speaker allows users to monitor partyline communications hands-free, while the push-to-talk functionality provides direct control over when the microphone is active.
Flexible Two-Channel Intercom Control
The KB-702 provides access to two Clear-Com partyline channels, making it useful when production personnel need to communicate with different teams or departments. Four programmable operating modes can be configured using the station's internal DIP switches, allowing the unit to be adapted to different communication workflows.
For users who need private listening or a more controlled communication environment, the KB-702 supports external headsets and telephone-style handsets in addition to its integrated speaker.
Designed for Professional Production Environments
A balanced local program input with independent level control allows program audio to be incorporated into the intercom system. The KB-702 also provides visual and audible call signaling, helping operators recognize incoming calls and communication requests even in busy production environments.
The station's microprocessor-controlled operation provides reliable switching and communication control, while the available 4-wire daughter board can expand the station's capabilities for systems requiring additional audio connectivity.
Installation Options
The compact KB-702 can be installed in several ways depending on the application. It can be wall mounted, installed into a console, or used with an optional V-Box for portable or desktop applications.
This makes the KB-702 a practical choice for fixed communication positions such as:
- Theater stage and backstage locations
- Broadcast studios and control rooms
- Live event production areas
- Houses of worship
- Performing arts facilities
- Production and technical offices
- Commercial intercom installations
