1 – Overview
The unD6IO Dante Audio interface is 4x2 Dante/AES67 multi-IO wall plate interfaces designed for in-wall installation
into 2-gang US junction boxes. Its form-factor and I/O density make it easy to put Dante connectivity close to audio
sources used in professional AV installations – thereby eliminating costly and interference prone analog wiring, power
supplies and giving a clean, finished look to an AV installation all while providing the superior audio system flexibility
with Dante audio networking.
Figure 1 - unD6IO Overview
The unD6IO features two balanced line-level inputs on XLR connectors. Each input features a software controlled mic
preamp with software switchable 48V phantom power.
The unD6IO also features two sets of stereo line-level audio connections for consumer audio device connectivity. The RCA
inputs (IN 3/4 A) and 3.5mm stereo input (IN 3/4B) are software selectable to be used as two independent stereo inputs
(each mono summed), or summed together as shown in the following signal flow diagram.

All four input paths from both the balanced and unbalanced inputs are digitized and then introduced as discrete channels
on the Dante network. In addition to the input functionality, the unD6IO also features two output channels which can be
received independently from the Dante network. The outputs are available on the front panel via a 3.5mm stereo jack
output connector and also on a 6-way de-pluggable Phoenix style connector on the side of the unit. The Phoenix audio
output connections are intended for use with a companion wall plate (sold separately) and installed in a 3-gang junction
box.

User Manual
Connection to the Dante network is provided by a single Ethernet RJ45 connector on the back of the unit. The unD6IO is
PoE-enabled which allows the unD6IO to be powered over its network cable from a suitable PoE source (IEEE 802.3af)
eliminating the need for a local power supply. This is particularly useful as the unD6IO can then be mounted in remote
location 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 by QSC unIFY Control Panel application (V2.0 or later) or
supporting DSP partner software can be used to configure the device-specific features.
The unD6IO also supports third party control systems allowing external configuration of its settings such as phantom
power and input gain in real time. Further information on 3

1.4 – Mounting and Installation
A typical installation will involve mounting the wall plate into a pre mounted 2-gang or larger wall box, standard drywall
bracket or mud ring. Before starting, make sure the wall box where the unD6IO is to be installed is pre-wired with a
suitable CAT5e or better 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 mid-span injectors
manual if unsure which port is which). The unD6IO packaging includes all of the necessary screws for mounting the
product and the included Decora wall plate.
*Note: All Attero Tech by QSC products are tested using UTP cabling and it is recommended that UTP cabling be used
when installing them. STP cabling can be used for installation though care must be taken not introduce grounding issues
into the system by doing so.
Attach the network cable from the switch/mid-span injector to the Dante I/F port of the Dante unD6IO. 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 unD6IO into the wall box taking care to not trap the cabling. Once fully in
place, secure it with the screws provided. Once the unit is secured in the wall box, fit the Decora plate over the front of
the unit and secure it with the screws provided with it. It is recommended to not over-tighten the screws that attach the
included Decora wall plate to prevent cracking it.

1.5 – Error Reporting
The unD6IO is equipped with error reporting features. Upon power up, the front panel power LED will briefly light red and
then change to green if the device boots successfully. If the LED remains on solid red, this indicates a device failure. If
power cycling the unit does not correct this problem, contact QSC technical support.
1.6 – Hardware Connections
The unD6IO provides balanced audio outputs to external analog audio equipment. Refer to the following diagrams and
instructions for connecting different types of audio devices to the outputs of the unD6IO. Professional grade audio cabling
is recommended to achieve the best audio performance throughout the system.

1.7 – Factory Reset
The unD6IO has a factory reset option. Using it will reset all the devices parameters back to their factory defaults including
all the Dante settings such as device name, channel names as well as the device settings such as input select. The devices
IP address mode is also reset back to getting a dynamic IP.
Access to the factory reset button is through a small circular hole on the
underside of the unit, next to the ventilation cutouts.
To use the factory reset, insert a small screwdriver or paperclip into the
hole to activate the factory reset switch. There should be a noticeable
“click” when it’s activated. Hold the switch in for 5 to 10 seconds then
release. If the factory reset was successful, the unit will actually reset
indicated by the power LED will turning red.

obtained from the Audinate website
about setting up routes on a Dante network can also be found on Audinate’s website.
*Note: When using Dante controller, the unD6IO will be shown using a default device name of “unD6IO-######” where
‘######’ is the last six characters of the devices MAC address.
Configuration of the unD6IO’s specific features are carried out using the Attero Tech by QSC’s unIFY Control Panel
application. This application is available for download on the QSC website. It should be used to configure and modify the
device specific features at the time of system installation and commissioning.
2.1 – IP Address Setup
********************************************************* IMPORTANT ******************************************************
Failure to correctly configure IP addresses will not allow an unD6IO device to correctly authenticate in the unIFY Control
Panel software and while it will show up in Dante Controller, the devices parameters will not be available. The input and
output channels also won’t be visible and routing of audio to and from the device will not be possible.
*****************************************************************************************************************************
In order to configure an unD6IO, both to set up internal parameters and also setup audio routing, the PC/Mac will need
to be able to communicate with the devices over the network. While all Dante devices will be discovered regardless of the
IP address setup on the PC or Mac, communication can only occur if the PC/Mac and the device have compatible IP
addresses.
By default, the unD6IO is set to get a dynamic IP address. As with all Dante devices, if the unD6IO does not find a DHCP
server to retrieve an IP address from, it will give itself an local link address sometimes also known as an automatic private
IP address (APIPA) instead. A local link IP address is always in the range 169.254.x.y.
To ensure communication, the PC/Mac can either be set to get a dynamic IP address, or be given a static IP address in the
range 169.254.x.y. The PC may require a restart if its IP address is changed for the change to take effect.
In some applications, IP addresses of devices may need to be set to something specific and that can be done once initial
communication has been established. Bear in mind however that if a static IP address is assigned to a device and that
static IP address is in a different range to the IP it was previously using to communicate with the PC/Mac, the PC/Mac will
lose communication with the device until such time as the PC/Mac IP address is also changed to an IP in range of the
devices new IP address.
Further information on IP setup for an audio system using Dante™ can be found in the FAQ’s on the Audinate website
party tool, the audio routing may be carried out using Audinate’s Dante Controller. Dante Controller can be
and is available for both Mac and PC. Instructions on how to use this application and

2.2 – Software Control and Control
The unD6IO is fully supported in unIFY Control Panel v3.2 and newer software. For a full description of the software and
configuration features refer to the integrated help documentation within the unIFY Control Panel application.
2.3 – 3rd Party Control
The unD6IO supports 3rd party control allowing external system to manage the unD6IO’s settings such as phantom power,
mic/line gain options and control of presets.
2.4 – Control Interface Type
There are two control interface types available. The first type is a Dante™ proprietary interface (-C) which is typically used
by devices already that have built-in support for Attero Tech by QSC devices. The second type supports a 3
interface (-U) and is available to anyone to use with any device capable of sending and receiving UDP messages.
The type of command interface a specific device supports is defined by the Dante™ firmware it has been loaded with.
There are two methods to determine which Dante™ firmware and thus which command interface that is:
1) unIFY Control Panel V2.0 or later: Right-clicking on the device in the device list, mouse over the “Device Info”
option and then look for the “Control Type” option. A “-C” means the device is using the Dante™ Proprietary
All Attero Tech by QSC “un” devices ship with the –U control option. However, this control option can be easily changed
in the field by updating the device’s firmware. Firmware updates can be done within unIFY Control Panel Software
and later). The latest firmware .SFU files can be downloaded from the Attero Tech Product Firmware page on the QSC
website.
interface. A “-U” means the device is using the Direct UDP interface.
2) Dante™ Controller”: Double-click on the device in question in the routing grid to display the “Device View” form,
select the “Status” tab and look for the “Product Version” and “Firmware Version” parameters in the “Device
Information” section.

2.4.2 – Using the Command interface
In order to make use of the control interface, regardless of type, the unD6IO and the controlling device need to be on the
same physical subnet and need to have IP addresses in the same range. The control devices should then be able to
converse with the unD6IO without any further configuration necessary.
