Sonifex CM-CU21 Commentator Unit 2 Commentators & 1 Guest

The CM-CU21 is a high quality, portable Commentator Unit. Its sturdy construction and features make it suitable for use in a wide variety of environments. The unit has all the features needed to ensure 2 commentators can provide their expertise, together with a guest position or co-commentator. The guest position can alternatively be used as a line-level input for international sound or special effects such as the sounds of the action and spectators.

A limit indicator on the main panel shows when the adjustable limiter on the mix outputs is active, and a bright 21 segment LED PPM meter, which can be disabled, shows the main output level. Two talkback output channels, with a built in limiter and adjustable gain, are available to each of the two main commentators and they can be linked to provide simultaneous operation.

A wide input gain range and switchable phantom power on each commentary position allows support of a variety of microphone types including low output ribbon mics, headsets and high output phantom powered microphones. The microphone level controls are accessible on the front panel but can be protected from adjustment by an optional cover plate if required (CM-CU21CP).

There are 4 transformer balanced return audio inputs which, along with the commentator inputs, are routed to the headphone monitor controls. The headphone input controls are very comprehensive allowing either of the two main announcers total control so that any monitor input can be adjusted in volume and sent to either the left, right or both ears.

A GPIO port gives an independent open-collector driven output indication for any of the three active On-Air or four talkback channels. Four remote inputs provide an external call/alert to each of the talkback controls which flashes the selected T/B button amber when used, to indicate active talkback. The unit has a built in line-up tone generator for easy channel identification and cabling checks.
