Sonifex AVN-CU4-DANTE Configurable Dante Commentary Unit for 4 Commentators

Description

The Sonifex AVN-CU4-DANTE is a portable commentator unit using Dante® AoIP. It is a dual version of the AVN-CU2-DANTE providing four mic/line inputs with a wide, adjustable gain range and four stereo headphone outputs with lockable jack sockets, suitable for operation by three or four commentators.

 

Fully featured, this unit allows you to handle virtually any commentary situation with both Dante AoIP and 4 wire connections, dual redundant Dante networking and multiple AC/DC/PoE+ power options. Up to 48 rotary encoders can be used on inputs, outputs or cross-points, allowing talkback feeds, commentary and audio mixing to be handled in one unit.

 

It has an abundance of 4 wire connections on the rear panel: 4 x analogue line inputs on XLR sockets with latching locks, 6 x analogue line outputs on XLR plugs and an RJ45 AES3 stereo input & output. These connections can act as a simultaneous analogue backup to the Dante AoIP connections.

 

The featureset is as per the AVN-CU2-DANTE, with the following differences. There are two displays with a doubling of operational controls:

 

• 4 x On-air buttons.
• 4 x Page buttons, 2 for each half of the display.
• 4 x Cough buttons.
• 8 x Talkback buttons, up to 4 for each user and
• 3 x User buttons.
• 12 x rotary encoders.
• 8 x pages of 6 rotary encoder positions (48 in total).

 

Similar to the AVN-CU2-DANTE, the illuminated Sonifex logo acts as a power indication and illuminated LEDs indicate network clock status, AoIP Primary and AoIP Secondary link status, PoE+ Primary, PoE+ Secondary and AC power active.

 

The front panel houses 4 x locking mic/line inputs with +48V phantom power indication and 4 x headphone outputs on locking 6.35mm jack sockets.

 

The unit has dual redundant network ports on both RJ45 (PoE+ using 2 x Neutrik EtherCON® connectors) and SFP cages.

 

To power the unit, as well as the dual PoE+ ports and 12V 4 pin XLR DC input, there is an AC mains input on an IEC inlet, with a universal supply.
