T Do not use the DPRO Adapter if it is not functioning properly, has fallen or been damaged, has
become wet or if parts of it have been immersed in water.
T If disruptions occur during operation:
Immediately disconnect the DPRO Adapter from audio sources and/or audio sinks.
T Do not operate the DPRO Adapter in environments where flammable or explosive materials,
gases or vapors are present or might occur.
2.5 Intended use
The DPRO Adapter is designed for converting the signal of an analog LINE/MIC or digital AES/EBU
audio signal into a DanteTM signal. DanteTM signals can also be converted into analog LINE signals.
2.6 Foreseeable improper use
The DPRO Adapter is not suitable for use outdoors and in potentially explosive atmospheres.
The DPRO Adapter is a 2IN, 2OUT breakout box designed to connect legacy audio equipment to
the Dante network. It features high-quality microphone preamps and 2 Dante ports for either redundant setup or daisy chaining. Audio parameters are adjusted by the DPRO Controller app.
All the connectors are lockable and, together with the removable rubber protector, offer a reliable
solution for tough stage conditions. With optional mounting brackets or a rack panel, the box can
be mounted below tables, in floor boxes, racks or on the truss.
4.3.3 Modes and switching logic of the DPRO Adapter
Switchable contacts in the DPRO adapter work in 2 ways:
• If the signal is analog, connect channel 1 and channel 2 (valid for input and output).
• If the signal is AES, connect channel 2 only (valid for input and output).
AES carries 2 separate signals over 1 physical cable. Therefore AES is occupying both channels and channel 1 becomes inactive. It's not possible to combine an analog signal on channel 1 and AES on channel 2, as this would
mean 3 separate signals are present. In this case channel 1 will have a priority and only the analog signal will be
present. This is valid for input and output.
w CAUTION
Danger of hearing damage!
Signal peaks may occur as a consequence of incorrect connections.
T Do not connect AES/EBU signal to input 1.T Do not connect amplifiers or other analog devices to output 2 (AES) if there is no connection on
DPRO Controller allows to control audio parameters, monitor the status of the device, recall, save and load presets. The
app is available for PC and Mac.

T Do not use damaged devices under any circumstances.
5.2 Connecting devices with the DPRO Adapter
The DPRO Adapter can be connected to a DanteTM network via a standard 1 Gbit/s twisted-pair
Ethernet cable (CAT5e). This connection is responsible for the data transfer as well as for the power
supply. Depending on the cable length and shield, we do not recommend installing cables parallel
to power supply lines. To disconnect DPRO Adapter from power, the PSE or PSE’s (switch or injector) have to be disconnected from the power outlet.
The DPRO Adapter requires a switch that supports PoE (48 V). If a switch without
PoE support is available, a PoE injector (compatible with 802.3af or 802.3at) must
be connected in series.
w CAUTION
Danger of hearing damage!
Signal peaks may occur when an audio source or sink is connected.
T Before making connections, mute the signal path of the peripheral devices.
w CAUTION
Danger of hearing damage!
Signal peaks may occur as a consequence of incorrect connections.
T Do not connect AES/EBU signal to input 1.T Do not connect amplifiers or other analog devices to output 2 (AES) if there is no
T Connect the device depending on the desired application:
Analog signal: Use channel 1 and Channel 2.
AES signal: Use channel 2.
T Connect the DPRO Adapter to the PoE switch using a network cable.T If the switch does not support PoE:
Use a PoE injector.
LEDs light up once the DPRO Adapter is supplied with power via the switch or the PoE injector. The DPRO Adapter is ready for operation. Set up the desired audio connection with the "Dante
TM
controller" software.
5.2.1 Power setup using a switch with PoE support
Audio connection
Network connection
Operation
The DPRO Adapter forwards information to the PoE switch indicating that it is a "Class 2"
device to ensure the correct power supply.
5.2.2 Power setup using a switch without PoE support
PRIMARY
For power and data redundancy, use 2x passive PoE injectors. Because they do not use the discovery process, switching between primary and secondary will not result in a short loss of audio. More
information about PoE please find in section "7.2 PoE (Power over Ethernet)" on page 41.
Do not use two different passive PoE injectors (such as from different manufacturers), because this might cause a short circuit and make the device inoperable.
information (audio, clock etc.) are sent across in
two separate networks to ensure uninterrupted signal flow in case one network goes down.

Network connection
5.3.2 Switched Mode (Daisy-chained)
In the Switched mode, you can daisy-chain several devices to increase channel count. Only passive
injectors are able to deliver steady power to all the daisy-chained units. Up to 2 devices can be
daisy-chained.
For daisy-chaining, use only a PoE Injector with no
class.

PoE stands for Power over Ethernet and describes a practice for using a single CAT5e (or higher) to
incorporate both power and data in the single cable.
Few advantages:
• Easy setup
• Single cable run up to 100 m
• Using PoE doesn’t require certified electrician as the power loads are small
• Existing network infrastructure can be used
7.2.1 Definitions
PD (Powered device) – device that is connected to PSE and thus is powered by it.
PSE (Power Sourcing Equipment) – device that provides power to PD, Switch or injector
PSE Types
In our case, we consider only following two types of PSE devices.
• PoE Switch: a switch that offers possibility to power PD. Switches use PoE classification.
• PoE Injector: typically a single port device for powering 1 PD. These exist with classification
(active) or without (passive).
The term class refers to a maximal power output (see table below).
Appendix
7.2.2 PoE Standards
These standards are part of IEEE 802.3 general standards.
802.3 af – defines PoE classes 0-3
802.3 at – uses the same classes, but introduces class 4 as well.
7.2.3 Classes and discovery process
Discovery is a process of PSE, determining the power requirements of the PD. Once PD and PSE are
connected, PSE sends out a short voltage impulse, reads the returned value and provides power
accordingly. This is valid for PSE with class (also called active).
No class (passive) PSE, acts as a classic power supply, hence no discovery is implemented, and PSE
supplies current at all times.
