This 2-line auto-nulling digital hybrid telephone interface module is designed for establishing IFB connections between main intercom and remote production trucks and enabling telephone calls directly from any intercom station in an Eclipse matrix. Onboard DSP processors provides greater than 40dB of trans-hybrid loss, as well as automatic echo cancellation for the highest intelligibility and audio quality. Enable or disable auto-answer and auto-disconnect. The interface is perfect for establishing IFB connections between the main intercom and remote production trucks, linking intercom communications between remote systems and enabling telephone calls directly to or from any intercom station in a Matrix Plus or other system.
