User Manual

1 - Overview

The unD3IO Dante Audio interface is a cost effective multi-IO wall box and is designed to fit into most dual gang US
junction boxes. Its size and I/O density make it easy to put Dante connectivity wherever it’s needed – near the audio
source or sink – thereby eliminating costly and interference prone analog wiring.

Figure 1 - unD3IO front view

The unD3IO features two Dante input and two Dante output channels. The analog I/O are configurable via software to
support different connectivity configurations. The XLR connector provides balanced mic/line audio to Dante output
channel 1. However, the second Dante output comes from one of three possible input mixes:

o A mono mix of the RCA jack inputs
o A mono-mix of the 3.5mm stereo jack inputs
o A combined mix of the RCA inputs and the stereo jack inputs

The user can select which mix they require through the control software.

The unD3IO has two output options. An XLR connector provides a balanced line output for analog output 1 only, and a

3.5mm stereo jack connector provides an unbalanced line level output for both analog output 1 and analog output 2.
Both output connectors may be used simultaneously.

Connection to the Dante network is provided by a single Ethernet RJ45 connector on the back of the unit. The unD3IO
is PoE-enabled which allows it to be powered over its network cable from a suitable PoE source (IEEE 802.3af-compliant)
and eliminating the need for a local power supply. This is particularly useful as the unD3IO can then be mounted in
remote locations where access to a mains outlet would be limited or indeed, non existent.

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 such as the mic/line gain options, phantom power setup for the XLR input, and the input
selection for the unbalanced inputs.

1.1– What’s in the Box

The unD3IO comes supplied with the following

o unD3IO device

User Manual

2.1 – Mounting

A typical installation will involve mounting the wall plate into the wall using an “old-work” type bracket or a pre­mounted wall box. Before starting, make sure the wall box where the unD3IO 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 manual for the midspan
injector 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 unD3IO. 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 unD3IO into the wall box taking care to not trap the cabling. Once fully in
place, secure 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 unD3IO 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– Balanced Source to Balanced Sink

To connect balanced sources to the unD3IO XLR input or connecting a balanced sink to the unD3IO XLR output, use a 2­core cable with a shield and connect positive output to positive input, and negative output to negative input using the
cable cores, and connect output ground to input ground using the cables shield.

Figure 2 - Balanced Source to Balanced Sink Connection

2.2.2 – Unbalanced Source to Balanced Sink

Use the following if using a single core cable with shield to connect a 2-wire unbalanced source to XLR input on the
unD3IO, or to connect an RCA or stereo jack unbalanced output signal from the unD3IO to a balanced input on another
device. Connect the positive output of the unbalanced source to the positive input of the balanced sink. Connect both
the source and sink input grounds together and short the negative input of the sink to ground at the input of the sink.

For the same connections but using a 2-core + shield cable, connect the positive and grounds as before but this time,
short the negative conductor to the shield at the source connection instead.

Figure 4 - 3-Wire Unbalanced Source to Balanced Sink Connection

2.2.3 – Balanced Source to Unbalanced Sink

Use the following if using a single core cable with shield to connect a balanced source to an RCA or stereo jack input on
the unD3IO or to connect the XLR output from the unD3IO to an unbalanced input on another device. Connect the
positive output of the balanced source to the positive input of the unbalanced sink. Connect both the source and sink
input grounds together and short the negative input of the source to ground at the output of the source.

Figure 5 - 3-Wire Balanced Source to Unbalanced Sink Connection

For the same connections but using a 2-core + shield cable, connect the positive and grounds as before but instead,
short the negative conductor to the shield at the sink end of the cable instead.

Figure 6 - 3-Wire Balanced Source to Unbalanced Sink Connection

2.2.4 – Unbalanced Output to an Unbalanced Sink

To connect an unbalanced source to unD3IO RCA or stereo jack input, or connect the stereo jack output to an
unbalanced sink, connect the positive output to the sink’s positive input and connect the grounds together through the
cable shield.

3 – Device Configuration

There are two parts of the device that require software to setup. First the audio routing, and second the configurable
features of the device itself.

The audio routing should be carried out using any application that supports Dante audio routing. This could be from a
3rd party manufacturer or be Audinate’s own Dante Controller. Dante Controller can be obtained from the Audinate
website (www.Audinate.com). Instructions on how to use this software and about setting up routes on a Dante network
can also be found on Audinate’s website.

*Note: When using Dante controller, the unD3IO will be shown using a default device name of unD3IO-###### where
‘######’ is the last six characters of the devices MAC address.

Configuration of the unD3IO specific features is carried out using the Attero Tech unIFY Control Panel application. This
application is available from the Attero Tech website (www.atterotech.com). It is used to initially configure the device
and can examine and modify the device specific features such as mic/line gain settings, phantom power, and output
boost options. The unD3IO features are supported in unIFY Control Panel V1.3 or later.

The unD3IO also supports 3rd party control systems by configuration with direct UDP messages. Further information on
using this facility can be found in the unIFY 3rd Party Control – Software API document available from the Attero Tech
website.

3.1 – Software Installation

After downloading the application, run the .exe and the first screen to appear will be the license agreement and options

3.2.4 – Device Controls

Each of the unD3IO inputs has different configurable options. The balanced input on the XLR (IN 1)
has mic/line gain options, and the phantom power control. The unbalanced outputs are fed into IN2
and the user has an Input Select option to determine audio from which unbalanced connector is
used.

The mic/line gain control gives the user three gain choices depending on the type of signal being
provided to the input. For a line level signal, select the 0dB option. The remaining two options are
for use if a microphone is to be connected directly to the input. If using a microphone as an input

The phantom power option is available for microphones that need it. The unD3IO provides 24V
phantom power. Check the box to turn phantom power on. Uncheck the box to turn it off.

The input selection option (shown right) allows the user to select which of the unbalanced inputs
are used as the second Dante output channel. Both RCA inputs are mixed by default to create
input source A. The 3.5mm stereo jack stereo inputs are mixed together to produce stereo source
B. The user can select which one of these sources the second input should be taken. The options
are source A only, source B only, or a mix of both source A and source B.

3.2.5 – Saving and Loading Settings

The unD3IO device settings can be saved or loaded by clicking on the icon to bring up the preset form.

source, choose the gain value that best suits the microphones output signal.

The unD3IO supports 9 internal presets with one of those presets used as the power-up default. It also supports saving
settings to, and loading settings from, a file for transferring to another device or backup purposes.

3.2.5.1 – Internal Presets

Settings in a device can be saved to an internal preset which can then be recalled at a later date. There are 9 internal
presets, one of which is the “Default” preset that is used to set device settings when the unD3IO is first powered on.
