Product Detail
The Sonifex CM - CU1 Commentator Unit is a top - notch audio device designed for single - commentator setups. It offers the same high - quality, robust performance as the CM - CU21, with features specifically tailored for single - commentator use. This unit provides a fully - featured commentator position and a line - level input. It has an individual commentator output and an additional output that mixes commentator and line input audio. The main panel features a limit indicator to show when the adjustable limiter on the main output is active, and a bright 21 - segment LED PPM meter (which can be disabled) to display the main output level. Key features include an individual output for the commentator position and a main mix output, a line input with configurable output and headphone options, talkback outputs selectable by the commentator with a built - in limiter and adjustable gain, 5 return audio circuits for headphones with individual level control, wide input gain range and switchable phantom power to support various microphone types, a user - preset adjustable limiter on the main output with activity indication, a built - in line - up tone for cabling checks, a 21 - segment LED PPM meter, transformer - balanced inputs and outputs, formica 'Sharpie' designation strips, a robust mechanical design protecting potentiometer knobs, and support for universal AC mains or 12 - 24 volt DC power. Technical specifications cover a wide range of input and output parameters, including gain range, maximum input/output levels, frequency response, noise, THD & N, and more. There are also detailed operational controls and indicators on the main, front, and rear panels, as well as configuration options accessible via the setup mode. Front and rear panel connections are clearly defined, along with physical dimensions and weight details.
Using the Sonifex CM - CU1 Commentator Unit is easy. First, connect your microphone to the XLR - 3 pin latching female socket on the front panel for the microphone input. If you have a line - level input source, connect it to the corresponding XLR - 3 pin latching female socket. For headphones, use the locking headphone jack on the front panel. On the rear panel, connect the prog, A, B, C, and D inputs using the XLR - 3 pin female sockets. Connect the outputs as needed, like the comm output, talkback outputs, and mix output. When powering the unit, you can use the universal filtered IEC for AC power (85 - 264VAC, 47 - 63Hz, 10W) or the XLR - 4 pin male for DC power (12V or 24V). Before using, it's a good idea to use the built - in line - up tone for initial cabling checks. You can adjust the gain, limiter, and other settings according to your needs. When using the talkback buttons, you can choose between momentary and latching actions. For the headphone routing, you can configure how different inputs are sent to the headphones. Regarding maintenance, keep the unit in a clean and dry environment. Avoid exposing it to extreme temperatures or humidity. If you need to clean it, use a soft, dry cloth. If there are any issues with the potentiometer knobs, be careful as they are protected by the robust design. If you want to change the configuration options, access the setup mode. You can save and load options to/from permanent backup or return to factory defaults as necessary.
