The AVN-CU1 is a Dante® commentary unit designed for a single commentator, combining professional broadcast functionality with an intuitive, compact interface. Expanding the Sonifex range of Dante commentary solutions, it offers a easy to use, straightforward microphone and headphone setup while maintaining a comprehensive feature set at a cost-effective. Designed for ease of use in live sports and studio environments, the AVN-CU1 provides clear control over monitoring and routing. The integrated headphone amplifier features five inputs; three Dante talkback channels, Dante programme audio, and sidetone, each with its own dedicated level control via individual potentiometers. Audio output routing is managed using illuminated pushbuttons, providing clear visual feedback of signal paths
Product Features
4 channel Dante AoIP.
Potentiometers control mix levels of up to five sources into the user’s headphones: Sidetone, Programme, Talkback A, B and C.
Sources (except for sidetone) are accompanied by an illuminated push button that routes the mic/line input to the relevant Dante output (On Air, T/B, A, B, and C).
Push buttons have removable caps, allowing you to change the text for your specific application.
A scribble pad spans all buttons to allow quick and easy source or destination labelling.
Sources, (except for sidetone), are accompanied by a 3-position toggle switch to route audio to the left, right or both channels of the headphone output.
The GPIO button can be used to call for technical help, identify users, or for your own remote function.
An OLED display for configuration, status indication (Clock, Link, PoE and DC) and active metering scale of the bar graph meter (dBFS/VU).
A rotary encoder is used to navigate the menu and adjust settings.
A curved LED meter displays the audio output level, offering daylight visibility with a user-selectable scale (VU or dBFS).
RGB LED downlighting under the unit indicates status (e.g. ON AIR), or can simply provide decorative lighting.
Compressor/Limiter on the microphone stage.
