1 – Overview
The unDIO2x2 is a 2-in/2-out audio interface utilizing Audinate’s Dante protocol. It's ideal for adding 2 channels of
Dante audio I/O in a small, unobtrusive form factor. The two inputs use 3-pin depluggable connectors for balanced or
unbalanced I/O connectivity and support either mic or line level signals. Each input also features a 24V phantom power
option. The two outputs also use 3-pin depluggable connectors and each provides a balanced line level output. Each
output also has an optional +10dB analog boost.
Connection to the Dante network is provided by a single Ethernet RJ45 connector on the back of the unit.
The unDIO2x2 can be powered by a 12V DC wall wart (ordered separately) but it also supports the use of PoE instead.
This allows the unDIO2x2 to be powered over the network cable from a suitable PoE source (IEEE802.3af). The PoE
power option is particularly useful if the unDIO2x2 is mounted in a remote location where access to a mains outlet is
limited or indeed, non existent.
The unit comes in a small form factor with integrated mounting bracket allowing it to be mounted discretely in small
spaces (such as under desks) close to the sources or sinks thus reducing the amount of analog cabling that may be
required.

Audinate’s Dante Controller or other 3rd party manufacturer's Dante routing software can be used to control the audio
routing configuration of the device while the Attero Tech unIFY Control Panel application can be used to configure the
device-specific features.
The unDIO2x2 also supports control by third party systems allowing external configuration of its settings such as
phantom power and input gain in real time. Further information on 3
rd
party control can be found later in this
document in section 4.
