1. Introduction
The DD2 and DD4 devices are gateways with 2 inputs / 2 outputs and 4 inputs / 4 outputs
respectively, between analog audio and the Dante ™ AoIP protocol.
The DD2 and DD4 devices have been designed to transmit line signals in a fixed installation,
so their connectors are of the 3.5mm euroblock type.
These devices will allow you to send an audio signal from one point of the installation to
another using the existing network infrastructure or insert / extract Dante ™ signals from
third-party devices that use this protocol.
2. Features
Sample frequencies supported
44.1 / 48 / 88.2 / 96 kHz
Cuantification (Bit depth):
According to configuration (1 ms default).
Balanced. Euroblock 3.5mm connector
Servo-balanced. Euroblock 3.5mm

RJ45 port for LAN connection. Allows PoE (Class 0 802.3af).
Next to the RJ45 connector you will find two LEDs indicating the status of the device:
The device is connected to the local network (LAN).
Sending and receiving packages.
- PoE 802.3af. The power of the device is immediate and through the Ethernet cable
itself. A switch or PoE injector is necessary.
- External power supply. If we do not have a switch or PoE injector, we can use an
external powe supply. The required voltage is 24 Vdc, at least 500mA of current is
required.
Device settings
The device configuration will be done using the DANTE ™ Controller application.
This is a free application available on the Audinate website (www.audinate.com).
Through this application we can:
● Route the audio signals present in the DANTE™ network.
● Identify the DANTE™ devices present in the network automatically.
● Edit features of these devices.
● Label the signals.

To make use of all the Dante Controller functionalities, we recommend that you go to its
manual, which you can download from the Audinate page.
https://dev.audinate.com/GA/dante-controller/userguide/pdf/latest/AUD-MANDanteController-4.1.x-v1.0.pdf
1. Connect the analog audio signals to the emitting and receiving devices according to
your needs.
2. Connect the devices via Cat5e or higher cables to the local network (LAN).
Remember that if you do not use PoE switches you will have to power the devices
with an external source.
3. Perform signal routing through the Dante Controller application
When you open Dante Controller you will find the “Routing” view. In the upper part will
appear the devices that can act as transmitters and the left part those that can act as
receivers.
To see the channels of each device, click on the + symbol next to each device.
To do the signal routing you only have to click on the intersection between sender and
receiver. Once routing has been performed the symbol will appear at the intersection.

Automatic IP
By default, DD2 / DD4 devices come with the automatic IP option selected. This means that if
you have a DHCP server in your local network, it will distribute IPs to all devices with the
automatic IP option enabled, including your PC. In case of not having a DHCP server, the
devices will auto-assign an IP belonging to subnet 169.254.0.0.
2.2.3. Network level configuration

DD2/DD4
USER MANUAL
VERSION 1.1
DD2/DD4 www.workpro.es 11
To activate the automatic IP option in your Windows PC go to the Network and Sharing Center
/ Connection: Ethernet / Internet Protocol 4 Properties (TCP / IPv4) and configure the IP
address of your PC as automatic.
Static IP
On the other hand, DD2 / DD4 devices also offer the possibility of working with static IP. To
select this IP address mode, having your PC in the same subnet as the devices, and through
Dante Controller, double click on the device to be modified in the "Routing" window. In the
pop-up window "Device View" go to "Network Config" and select "Manually configure IP
Address", fill in the appropriate fields.
