1 – Overview
The unD32 is a 32 channel Dante break out box (BoB) and comes in a 19-inch 1RU rack mountable chassis that is
approximately 7.5 inches deep. Its 32 analog output channels are fully balanced with grounding and shielding per
AES 8-2005 standards. Each output has the following features:
oRear panel connectors using a 3 pin Phoenix style connector receptacle with a pin pitch of 3.81mm (150mils)
oCapable of a maximum output level of +20dBu before clipping
oIndividually adjustable volume over a 60dB range using the unD32 internal volume controls
oIndividual mute facility
oCan be assigned to any stream available on the Dante network the D32 is connected to
In additional to the volume and mute controls per channel, there is also a master volume and master mute. All the
volume and mute controls can be accessed by using the unD32 unIFY control panel.
The unD32 includes front panel controls which consist of a 16x2 backlit character display and a 6 button keypad.
These can be used to both assign named Dante audio flows to each of the 32 balanced outputs and control the output
volume of each channel directly on the unit itself.

Figure 2 - unD32 Rear
The unD32 features both primary and secondary Gigabit Dante network connections as well as a third “local” Gigabit
port. All three of these network interfaces are available via separate 8P8C modular connector receptacles (RJ- 5) on the
rear panel of the unit. The three ports allow the unD32 to be run in single network “Switch” mode or in dual network
“Redundancy” mode.
The unit is powered using an external universal 2 V DC power supply (100VAC - 2 0VAC, 50Hz - 60Hz). The specific
part number used to order the unD32 determines what style of mains connector the supplied power cord comes with.

2 – Installation
The unD32 comes ready to be mounted into a standard 1RU rack. The rack mount tabs are built in to the front panel of
the unit (rack screws are not supplied).
2.1 – Power Connection
Attach the provided power supply to power connector on the back of the unD32. The use the provided AC power cable
to connect the power supply to standard AC outlet. There is no “on” switch so the unit will power up as soon as the
power connection is made.
*Note: It is recommended to attach the power supply to the unD32 first, then connect the power cord to the power
supply and finally, plug the cable into the AC outlet.
2.2 – Network Connections
There are two configurations for network connectivity. Each is listed below. Select the configuration that best fits your
application.
2.2.1 – Single Network Connection
This type of network connection is probably the most common and uses a single Ethernet cable connecting the unD32
to the Ethernet switch that is providing the Dante network to the area of the facility where the unD32 is installed. The
Ethernet cable can be plugged into any of the three ports on the unD32.
*Note: This is the default configuration and the unD32 should require no configuration changes to wor in this mode.
However, if problems occur when using this type of networ topology, ma e sure the unD32 is configured for switch
mode (refer to Dante Controller User’s Guide for information on how to do this).
The unused ports of the unD32 may be used to connect other devices to the Dante network if required. However, as
the unD32 acts as a switch, devices connected in this must count the unD32 as a switch hop.
2.2.2 – Redundant Network Connection
This type of network connection relies on the Dante network in the area of the facility where the unD32 is to be
installed being provided by two completely separate networks. This type of network topology provides redundancy
through duplication to each of the devices units connected to the network. To use the unD32 in such a system, connect
the primary port to a switch on the primary network and then connect the secondary port to a switch on the secondary
network. When using this type of network topology please make sure the unD32 is configured for redundant mode
(refer to Dante Controller User’s Guide for information on how to do this).
*Note: It is recommended before using redundancy mode that the Audinate documentation on redundancy be reviewed
to ensure the full implication of its use on both the networ design and the system design are understood. Problems will
result when redundancy mode is enabled on the unD32 if the audio networ s are not designed and setup correctly to
wor in this manner.
In this mode, the local port can be used as a control port as it can access the device regardless of whether the unD32 is
operating on its primary or secondary interface (only one of which will be active for audio transfers at any one time).

2.3 – Audio Connections
The unD32 unit comes shipped with 32 Phoenix style, screw down, connectors pre-installed into the 32 audio output
connector ports.
2.3.1 – Balanced Destination
To connect a balanced input on a destination device to an unD32 output, connect the positive and negative connections
of both the unD32 output and the destination devices input respectively. Use the shield of the cable to connect the two
GND pins together. If the cable does not have a shield, use a free internal core instead.
Figure 4 - unD32 Output to Balanced Destination
2.3.2 – Single Ended Destination
To connect a 2-wire unbalanced input to an unD32 output, connect the positive input of the destination device to the
positive output of the unD32. Connect the GNDs together through the cable shield. If the cable does not have a shield,
use a free core instead. Leave the unD32 negative output floating.

3 – Front Panel Operation
The front panel allows the user to:
oView and select which of the available Dante audio channels is mapped to each of the unD32 audio outputs
oAdjust the signal level of each analog audio output from +20dB down to -60dB
oMute an output.
3.1 – Front Panel
The front panel contains a 16-character by 2-line LCD screen and a six button keypad. A depiction of the front panel is
shown in Figure 6.
Figure 6 - unD32 Keypad & LCD
The six button keypad allows the user to traverse the various control screens. Four keys provide the ability to move the
cursor Up, Down, Left, and Right. The key in the center with a check mark is the Enter key. The key marked with a red
“X” at the bottom left is the Cancel Key.
3.2 – Cursor
The LCD will always display a cursor during operation of the unD32. The cursor is shown as a blinking block at the first
character of a field. The cursor indicates the field that is currently selected. The cursor will initially be in the first
character of the unD32 Output Channel field in the Channel Select screen.
3.3 – Transition between Screens
Each channel has two screens associated with it: the Channel Select screen and the Volume Select screen. These
screens are described in subsequent sections of this user’s manual.
A single press of either the Up or Down button will cause the screen to transition to the Volume Select screen for the
current channel. Another press of the Up or Down button will cause the screen to transition to the Channel Select
screen for the next higher or next lower Output Channel respectively.
*Note: The channel number wraps from 32 to 1 in the Up direction and 1 to 32 in the down direction.

3.4 – Channel Select Screen
The Channel Select screen provides the user a method to select which available audio stream on a Dante network for
each individual output. This is also the initial screen the unD32 will show after power up. Figure 7 below shows a
representative of it.
C H 0 1 : C H A N N A M E
LEVEL
Figure – Channel Select Screen
The top line shows the selected channel number (1 – 32) and name of the audio stream that the selected channel is
currently receiving from the Dante audio network. The channel number is always shown as two digits so channels less
than 10 will have a preceding ‘0’. Only the first 10 characters of the stream name will be visible. If no assignment has
been made, “NONE” is shown in this field.
The bottom line shows the signal level of the selected audio channel. The level meter provides an approximate analog
output level and is displayed as an extending horizontal bar. If no bar is shown, the output level is - 0dB or below,
while a bar that extends up to the right-hand edge of the screen represents +20dB full scale output and possibly
clipping.
While in the Channel Select screen, pressing either the Left or the Right button will cause the cursor to move between
the first position of the channel number and channel name fields. To select a Dante audio channel the cursor should be
moved to the first position of the channel name field.
Once in the Channel Name field, the Up or Down buttons can be used to cycle through all the available audio channels
in the Dante network that can be received by the unD32. Once the desired channel to receive has been found, the
channel selection can be finalized by pressing the Enter button while the desired audio channel is displayed. No
channel is selected until the Enter button is pressed. The “None” option may also be selected to select no audio for a
channel.
To transition to another channel or to the Volume Select screen the cursor needs to be in the first character of the
Output Channel field. Pressing either the Left or Right buttons will accomplish this.
