Sonifex AVN-CU4 Configurable Dante Commentary Unit for 4 Commentators

Dante Connectivity & Audio Routing

The AVN-CU4 supports up to 16x16 Dante AoIP input and output channels, with up to 16x16 simultaneous Dante streams. Once configured, its mix engine enables flexible routing of signals between physical and AoIP connections, controlled via programmable buttons and rotary encoders. 

Two locking Ethernet ports on the back panel are used for AoIP connectivity and can be configured to function in either redundant or switched mode, via the Dante Controller interface.

User-Friendly, Intuitive Control

• 12 push-button rotary encoders for level, pan, and mix adjustments.
• 8 pages of 6 rotary encoder positions (48 in total).
• 24 programmable user buttons with customizable key-cap text.
• Full-color TFT display for real-time audio and system monitoring.
• Customizable encoder colors for quick identification of sources and destinations.
• Embedded web server for remote configuration and control.

Standard Operations Available

• On-Air control for each commentator position, used to connect mic audio to the main output, either over AoIP or via physical audio connections
• A cough control is available for each commentator position, which temporarily takes the commentator off-air while pressed
• 4 T/B (talkback) controls are available for each commentator position
• User buttons can be programmed to perform various functions using the web server, such as activating a physical GPO, a virtual GPO, a relay, or an event
• And more

Comprehensive Connectivity Options

• 4 analog XLR line inputs and 6 analog XLR line outputs on back panel.
• Rear-panel RJ45 ports provide AES3 or analog I/O, assignable as mic outputs (at line level), talkback, or program feeds.
• Dual redundant network ports via RJ45 and SFP cages, supporting long fiber runs.
• 10 configurable GPIO on a 15-way D-type connector, including one switched changeover output.
• AES/analog I/O can serve as an insert or exit point within the AoIP network.

Flexible Powering Options

The AVN-CU4 supports multiple power sources for maximum reliability:

• Power over Ethernet+ (PoE+) via Neutrik etherCON connectors (primary & secondary for redundancy).
• 4-pin XLR 12 VDC input for operation via an external PSU (available separately) when PoE is unavailable.
• AC mains with universal power supply.
