Clear-Com TW-12C CC/RTS System Interface

Bridge Intercom Systems Without Compromising Signal Integrity
The Clear-Com TW-12C is a professional-grade interface designed to connect separate intercom systems while maintaining full signal quality and operational compatibility. Whether you're linking Clear-Com to Clear-Com, Clear-Com to RTS, or RTS to RTS systems, the TW-12C ensures seamless audio and signaling between platforms. It is purpose-built to isolate power and grounding between systems, preserving the integrity of each network while enabling cross-platform communication.

Support Cross-Brand Intercom Integration with Ease
In mixed-technology environments, integrating different intercom platforms can create challenges in audio levels, signaling compatibility, and grounding. The TW-12C solves this by matching gain structures between systems and providing full signal translation—including Call signals—so users on both sides experience uninterrupted, clean communication. It enables full system integration without compromising performance, regardless of the brands in use.

Prevent Ground Loops and Audio Interference Across Systems
One of the most critical functions of the TW-12C is eliminating ground loop issues that can arise when connecting separate powered systems. The device maintains electrical isolation between connected systems, preventing unwanted hum, buzz, or interference. This makes it essential in permanent installations or touring setups where equipment is often powered from different sources or physical locations.

Translate Call Signaling and Balance Audio Automatically
Beyond audio routing, the TW-12C also passes and translates signaling between systems, ensuring full functionality of Call features across intercom platforms. Gain matching is handled internally, allowing the adapter to automatically align audio levels between connected systems. This feature helps avoid clipping, distortion, or signal loss, ensuring a professional and consistent experience for all users.

Achieve Clean Communication with Hybrid Nulling Capability
The TW-12C features hybrid nulling of up to 40 dB, allowing for clean duplex audio transmission between systems without noticeable echo or crosstalk. This is particularly important when connecting large, distributed intercom systems where signal reflections or feedback could otherwise degrade audio clarity. The hybrid nulling function ensures smooth, full-duplex performance even in complex setups.

Built-In Setup Tone Simplifies Installation and Testing
For system integrators and engineers, the TW-12C includes a built-in tone generator to assist with signal tracing and setup verification. This makes it easier to identify routing paths, verify connections, and confirm audio alignment without relying on additional test equipment. The tone function streamlines installation and ensures everything is operating as expected before going live.

Powered Directly by the Intercom Line for Simplicity
The TW-12C requires no external power supply, drawing its operating power directly from the intercom system it's connected to. This not only simplifies setup but also reduces the number of powered components in your system, improving reliability and minimizing wiring complexity. Its compact design and system-powered operation make it suitable for permanent installations and mobile rigs alike.
