2.1 – Mounting
A typical installation will involve mounting the wall plate into a pre mounted wall box. Before starting, make sure the
wall box where the unDX2IO is to be installed is pre-wired with a suitable cable back to a PoE enabled network switch or
mid-span injector. If a mid-span injector is being used, the cable should be connected to the port that supplies both
Ethernet and power (refer to the devices manual if unsure which port is which).
Attach the network cable from the switch/mid-span injector to the Dante I/F port of the Dante unDX2IO. If the switch or
mid-span injector is already running and PoE is enabled, the unit should power up and the green ID LED on the front of
the device should turn on.
With the cable attached, carefully place the unDX2IO into the wall box taking care to not trap the cabling. Once full in
place, secure it with the screws provided. Once the unit is secured in the wall box, fit the Decora plate and secure it
with the screws provided with it.
2.2 – Hardware Connections
The unDX2IO accepts and drives either unbalanced or balanced audio devices. Refer to the following diagrams and
instructions for connecting different types of audio devices. Professional grade audio cabling is recommended to
achieve the best audio performance throughout the system.
2.2.1 – Input from an Unbalanced Source
To connect a 2-wire unbalanced source to the unDX2IO, connect the positive output of the unbalanced source to the
positive input of the unDX2IO. Connect both the source and unDX2IO input grounds together, and short the negative
input of the unDX2IO to ground at the input of the unDX2IO.

To connect unbalanced sources with a 3-wire connection, short the negative conductor to the shield at the source
connection.
