Clear-Com TW-47 2-Way Radio Interface

Connect Two-Way Radios to Partyline Intercom Systems
The Clear-Com TW-47 is a dedicated interface unit that allows a two-way radio or walkie-talkie to integrate directly into a single channel of a standard two-wire partyline intercom system, such as Clear-Com or RTS. This compact device bridges mobile radio communication with fixed intercom infrastructure, making it possible for roaming crew members using radios to stay in communication with wired intercom users. It's an essential tool for productions requiring seamless communication across both mobile and stationary teams.

Compatible with Standard Two-Wire Intercom Systems
The TW-47 is built for direct compatibility with Clear-Com, RTS, and other compatible analog 2-wire intercom systems. It connects to any open intercom channel, providing both audio pass-through and keying capabilities using the Call signal. This functionality allows two-way radio users to interact with wired intercom stations as if they were on the same network, maintaining real-time communication across platforms without requiring separate infrastructure.

Works with Most Walkie-Talkies and Portable Radios
Designed for flexibility, the TW-47 connects to virtually any portable radio or walkie-talkie equipped with standard headset and microphone jacks. This enables it to support a wide range of professional radio models from major manufacturers. By offering this universal connection capability, the interface allows for broader equipment integration across a variety of production and event communication setups.

PTT Keying Enabled with Standard Call Signal
The interface uses the Call signal from the intercom line to key the transmitter on the connected radio, enabling push-to-talk functionality directly from the intercom station. This eliminates the need for complex wiring or custom switch configurations. The seamless integration of PTT functionality ensures that two-way radio users can communicate without disruption or missed transmissions.

Powered Directly from the Intercom Line
The TW-47 does not require an external power source—it draws power directly from the connected intercom line. This simplifies installation and setup, particularly in mobile environments or temporary systems where reducing the number of powered devices is a priority. The self-powered design adds to the reliability of the unit while minimizing cable clutter.

Adjustable Levels with LED Monitoring for Easy Setup
Transmit and receive levels can be adjusted independently to match the gain structure of both the intercom system and the connected radio. A bi-color LED audio level indicator provides instant visual feedback, ensuring optimal audio performance and avoiding signal distortion. This makes it easy for technicians to dial in clean, balanced communication between devices.
