Sonifex CM-CU21 Commentator Unit, 2 Commentator and 1 Guest Positions

The CM-CU21 is a high quality, portable Commentator Unit. Its sturdy construction and flexibility of features make it suitable for use in a wide variety of environments. It provides two fully featured commentator positions and a third guest position that can alternatively be used as a line-level input. Each position has an individual output, with two additional outputs providing a mix of all active commentary channels. 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.

• Individually switched 48V phantom power on all microphone inputs
• User preset adjustable limiter on main mix outputs with limit activity indication
