Attero Tech unD32
32 Channel Dante Breakout Interface


The Attero Tech unD32 32 Channel Dante Breakout Interface (BoB) is a 1RU interface for all types of commercial AV installations, such as those found in stadiums, convention centers, and houses of worship, among others. Each of the 32 analog outputs on the unD32 may be assigned to any Dante flow in the system, either by means of the front panel controls or using Audinate's Dante Controller Windows or OSX application. A 16x2 display shows flow names and signal levels for each of the 32 analog output channels.

In addition, each output level is individually controllable over a 60dB range plus mute. The unD32 features both primary and secondary Gigabit Dante network connections for full redundancy, as well as a third "local" Gigabit port. This port gives network access to other equipment in the rack (e.g. amplifier controllers, control devices, etc.) without the need for a separate Ethernet switch.
