Description of the Product4.3.3 Modes and switching logic of the DPRO Adapter
The mode in which the device operates (Analog/AES) is defined by the XLR connections and not by
the software (DPRO Controller).
This can lead to a mismatch between device's I/O connections and the presets in the DPRO Controller.
For example:
A preset that includes analog input will not load unless a cable is plugged into input channel 1

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).
Some examples of XLR assignments on the switchable contacts and the operating mode shown in the
DPRO Controller software.
No XLR CONNECTION

If there is no physical XLR connection to the device, no audio parameters can be adjusted in DPRO Controller software All channels are hidden in grey.

11

Description of the Product1st XLR IN/ 1st XLR OUT
Oparating mode: Analog

If there is a physical XLR connection to channel 1 only (valid for input & output), the device is operating in analog
mode.
Audio parameters for both cannels (channel 1 and channel 2 – valid for input & output) can be adjusted in DPRO
Controller software.
Channel 2 is hidden in grey at the top panel (valid for input & output), since there is no physical connection on it.

Description of the Product1st & 2nd XLR IN / 1st & 2nd XLR OUT
Oparating mode: Analog

If there is a physical XLR connection to channel 1 & 2 (valid for input & output) the device is operating in analog
mode.
Audio parameters for both cannels (channel 1 and channel 2 – valid for input & output) can be adjusted in DPRO
Controller software.

13

Description of the Product2nd XLR IN / 2nd XLR OUT
Operating mode: AES

If there is a physical XLR connection on channel 2 only (valid for input & output), the device is operating in AES mode.
No audio parameters can be adjusted in DPRO Controller software.
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 bepresent. This is valid for input and output.

14

User Manual – DANTETM Adapter NA2-IO-DPRO | BDA 573 V6 2021/11

Description of the Productw 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

output 1 (ANA).

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 Power over Ethernet Switch or a PoE injector. For
detailet information see 7.1 Technical Inforamtion.

Operation
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 "DanteTM controller" software.

5.2.1 Power setup using a switch with PoE support
Audio connection
Network connection

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

NPS-30W

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. Moreinformation about PoE please find in section "7.2 PoE (Power over Ethernet)" on page 48.
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.

For power and data redundancy, PoE is required on both ports.
Do not use a mixed setup (passive and active PSE) in a redundant setup.
Only use passive PSE (Power Sourcing Equipment) for true redundant setup because passive
PSE do not use the discovery process.
Therefore, switching between primary and secondary will not result in a short loss of audio.
Do not use two different passive PSE (such as from different manufacturers) since this mightcause a short circuit due to different pin assignment of the devices.

Appendix

7.2 PoE (Power over Ethernet)
PoE stands for Power over Ethernet and describes a practice for using a single CAT5e (or higher) toincorporate 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, can be a network 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 withclassification (active) or without (passive). Neutrik's NPS-30W is a passive PoE injector.
The term class refers to a maximal power output (see table below).

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.
802.3 bt – uses the same classes as 802.3 af and 802.3 at, but introduces class 5 to 8 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 areconnected, 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 deliver current at all times.
