1 – Overview
The u is a 2-in/2-out AES67 audio interface. It's ideal for adding 2 channels of AES67 audio I/O in a small,
unobtrusive form factor for installed sound applications. The two inputs use 3-pin de-pluggable connectors for balanced
or unbalanced I/O connectivity and support either mic or line level signals. Each input also features a 48V phantom power
option. The two outputs also use 3-pin de-pluggable connectors and each provides a balanced line level output. Each
output also features software adjustable volume control.
Connection to the audio network is provided by a single Ethernet RJ45 connector on the back of the unit.
The u can be powered by a 24V DC wall wart (ordered separately) but it also supports the use of PoE instead.
This allows the u to be powered over the network cable from a suitable PoE source (IEEE802.3af). The PoE power
option is particularly useful if the u is mounted in a remote location where access to a mains outlet is limited
or indeed, nonexistent.
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.

Attero Tech unIFY Control Panel application can be used to configure the device-specific features. It is also used to
configure its AES67 transmit and receive streams as well.
The u 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 3.5.
