Description: The CM-CU21 is a high-quality, portable Commentator Unit. Its robust construction and versatile features make it suitable for use in a wide range of environments. It offers two fully equipped commentator positions and a third guest position that can alternatively serve as a line-level input. Each position is equipped with an individual output, alongside two additional outputs that provide a mix of all active commentary channels. A limit indicator on the main panel signals when the adjustable limiter on the mix outputs is engaged, while a bright 21-segment LED PPM meter, which can be disabled, displays the main output level. Two talkback output channels, each with a built-in limiter, are available for the two main commentators and can be linked for simultaneous operation. A wide input gain range and switchable phantom power at each commentary position accommodate various microphone types, including low-output ribbon microphones, headsets, and high-output phantom-powered microphones. The unit features four transformer-balanced return audio inputs, which, along with the commentator inputs, are routed to the headphone monitor controls. These controls allow any monitor input to be adjusted and sent to either the left, right, or both ears. A GPIO port provides an open-collector driven output indication for any active On-Air or talkback channel, while four remote inputs enable an external call/alert for each of the talkback controls. The unit includes a built-in line-up tone generator for easy channel identification and cable checks. When activated, the test tone is routed to the desired output by pressing the corresponding on-air or talkback button. A range of customizable options allows the Commentator Unit to be tailored to meet operational and user-specific needs. These options include momentary or latching operation of the talkback buttons, the ability to permanently enable or disable any of the commentator inputs, default headphone signal routing, and main panel indicator illumination levels. Four return audio circuits are routed to the headphones alongside all commentator inputs, enabling individual level control of any source, which can be directed to the left, right, or both ears.
The CM-CU21 Commentator Unit is designed to facilitate seamless communication in environments such as broadcasting, live events, and production studios. The dual commentator positions allow for collaborative commentary, while the guest position provides flexibility for additional contributors or line-level inputs, enhancing the unit's utility in various scenarios. The individual outputs for each commentator ensure that their audio can be managed independently, which is crucial for maintaining clarity and control during live broadcasts.
The inclusion of a 21-segment LED PPM meter serves as a visual aid for monitoring output levels, helping to prevent audio clipping and ensuring optimal sound quality. The adjustable limiter on the mix outputs is particularly valuable in dynamic environments, where audio levels can fluctuate significantly. The talkback channels, equipped with limiters, provide clear communication between commentators and production staff, which is essential for coordinating live events.
The headphone monitor controls are a key feature, allowing users to customize their listening experience. The transformer-balanced return audio inputs ensure high-quality audio transmission, eliminating interference and maintaining signal integrity. Furthermore, the GPIO port and remote inputs enhance the unit's functionality, enabling integration with external systems for alerts and notifications.
The built-in tone generator simplifies setup and troubleshooting by allowing users to test channels and cabling quickly. Customization options further enhance the unit's versatility, enabling users to configure the system according to their specific operational requirements. Overall, the CM-CU21 Commentator Unit is a comprehensive solution for professional audio commentary, combining robust features with adaptability for diverse broadcasting environments.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. Two talkback output channels, with a built in limiter, 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, headsets and high output phantom powered microphones. There are 4 transformer balanced return audio inputs which, along with the commentator inputs, are routed to the headphone monitor controls.
With these headphone controls, any monitor input can be adjusted and sent to either the left, right or both ears. A GPIO port gives an open-collector driven output indication of any active On-Air or talkback channel and four remote inputs provide an external call/alert to each of the talkback controls.
The unit has a built in line-up tone generator for easy channel identification and cabling checks. When enabled the test-tone is routed to the required output simply by pressing the corresponding on air or talkback button. A flexible range of options allow the Commentator Unit to be customised to better suit the operational and user`s personal requirements.
These include options for momentary or latching operation of the talkback buttons, permanently enabling or disabling any of the commentator inputs, default headphone signal routing and main panel indicator illumination levels. 4 Return audio circuits that are routed to headphones along with all the commentator inputs. Any source can be individually level controlled and sent to left, right or both ears.
