Clear-Com TW-12C Intercom System Interface

TW-12C intercom system interface is designed for connecting one intercom system to another, without compromising the audio quality of either system. It provides system isolation and level matching to help you integrate mixed intercom environments while reducing common noise and grounding issues that can appear when tying systems together.

Intercom-to-Intercom Connectivity Without Ground Loops

The TW-12C is built for linking compatible partyline systems while keeping them electrically isolated. This isolation helps eliminate grounding problems between intercom systems and supports clean, stable audio when bridging separate system power and reference grounds.

Compatible Systems and Signal Translation

Designed for system isolation in multiple pairing scenarios, it supports Clear-Com to Clear-Com, Clear-Com to RTS, and RTS to RTS connections. To keep communications working as expected across the link, the unit passes through and translates signaling, and it also matches gains between systems so levels stay consistent between the connected intercom networks.

Audio Setup Tools and Performance

For optimizing performance in real installations, the TW-12C offers hybrid nulling up to 40 dB and includes a built-in setup tone to speed configuration and troubleshooting during commissioning or system changes. It is powered directly from the connected intercom system, which can simplify rack layouts by avoiding a separate power supply.
