Channel Talker MADI
MADI Signal Generator: 64 Channel
With Voice-over ID
Digital Audio Test Equipment –
The CT-MADI signal generator makes it possible for one person to setup or verify a MADI communication link easily, quickly, and accurately. The unit produces a hands-free audible sequential voice ID for each channel, eliminating the need for external generators or extra personnel to switch between sources. In addition to the voice ID’s, the CT-MADI includes four tone sets that will verify frequency response and level accuracy. MADI outputs are available on both COAX and FIBER. The unit can be locked to a variety of external references and generates a re-clocked Word clock.
In addition to a MADI output, there is a Reference AES DAR output and AES Audio output with the same signal that is on the MADI channels.
