It provides four analog inputs for the connection of microphones or audio sources with line output level. If required, a 48 V phantom power supply can be activated separately for each input. Four analog out- puts are available to connect speaker systems, recorders or units for signal processing; their level can be adjusted individually and they can be muted by means of separate switches.

Dante, an audio network developed by the company Audinate, allows transmission of up to 512 audio channels at the same time. Dante (Digital Audio Network Through Ethernet) uses a common Ethernet standard and is based on the Internet protocol. The transmission of audio signals is uncompressed and synchronized, with minimum latency. The advantage over analog audio signal transmission is a cost-effective connection of components via standard network cables and low susceptibility to interference, even in case of long transmission paths. In addition, signal routing between components that have once been connected can be changed by soft- ware at any time. In the Dante network, units configured as transmitters are used as signal sources. By means of the program “Dante Virtual Soundcard” from the company Audi- nate, it is also possible to use computers as signal sources and thus to feed audio files re- played on the computer to the Dante network. Units configured as receivers (e. g. amplifiers) receive the signals from the Dante network. The signal converter DADC-144DT pro- vides four transmitter channels (the signals of the analog inputs) and four receiver channels (the signals to the analog outputs). The trans- mitters and the receivers are assigned in the Dante network via the Dante configuration program “Dante Controller” (

The Ethernet interface is also configured via the program “Dante Controller” (

chap- ter 7.2). For correct configuration, knowledge in network technology is indispensable. Dante™ is a trademark of Audinate Pty Ltd. English English Page9 English PUSH

4 Setting up the Unit The unit is designed for installation into a rack (482 mm / 19”); however, it can also be used as a tabletop unit.

4.1 Rack installation

For rack installation, screw the two mounting brackets supplied onto the right and left sides of the unit (

fig. 1). In the rack, 1 rack space (= 44.45 mm) is required. 5 Connecting Units Prior to making any connection, switch off the units to be connected.

Connect microphones or audio sources with line signal level (e. g. CD player, preamplifier, mixer) to the input jacks INPUT SECTION (15). The jacks are designed for balanced signals. Audio sources with unbalanced signals can be connected via an XLR plug where the con- tacts1 and 3 are connected with each other. By means of the switches PH.PWR (16), individual jacks can be supplied with 48 V phantom power which some microphones (e. g. condenser microphones) require for operation. To activate the phantom power supply, engage the switch. Disengage the switch unless the audio source definitely requires phantom power. Caution! When the phantom power sup- ply has been activated, make sure that no microphone or audio unit with unbalanced output signal has been connected to the input; the microphone or audio unit may be damaged. To avoid switching noise, only use the switches when the unit is switched off.

The inputs OUTPUT SECTION (13) can be used to connect units with line level inputs such as amplifiers, active speakers, mixers, recorders or units for signal processing. The jacks pro- vide balanced signals.

For connection to a Dante network, connect the RJ45 jack NETWORK (14) to an Ethernet switch which supports at least Fast Ethernet (100MBits / s Ethernet). The LED indicator LINK (4) will light up when a network connection has been estab- lished; the LED indicator ACT (5) will light up to indicate network activity.

Finally, connect the mains cable supplied to the mains jack (12) and then to a mains socket (230 V/ 50 Hz). 6 Operation

Prior to initial switch-on, use a small screw- driver to set the controls for sensitivity ad- justment INPUT GAIN (2) and the controls OUTPUT LEVEL (7) to the left stop.

First switch on the signal sources con- nected to the inputs (15), then switch on the signal converter DADC-144DT with the POWER switch (10). After switch-on, the outputs will be switched on with a delay of a few seconds; then the LED indicator ON (9) will light up.

3) Use the controls INPUT GAIN (2) to adjust

the sensitivity of the inputs in such a way that the LED indicator SIG (1) will light with typical input signals and the LED indicator PK (3) will only light up with signal peaks. The LED indicator PK will light up contin- uously when the input is overloaded. In this case, reduce the input sensitivity or the level of the signal source accordingly.

Use the controls OUTPUT LEVEL (7) to match the signal level of the outputs to the input sensitivity of the units connected. The LED indicators SIG (6) will light up when a signal is available at the output.

6) After operation, first switch off the units

connected to the outputs, then the signal converter DADC-144DT and finally the audio sources connected to the inputs. 7 Configuration of the DanteNetwork The signal converter DADC-144DT is set up as transmitter and receiver in the Dante network by means of the program “Dante Controller”, available as a free download on the web- site of the company Audinate. The settings made via the program will be saved in the corresponding units of the Dante network so that the program is only required for network configuration but not for normal operation. The following system requirements apply to the computer on which the program “Dante Controller” is to be executed: Component Minimum requirements Processor 1 GHz RAM 512 MB Network Standard Ethernet interface (100 Mbit / s or Gigabit) or wireless LAN (WiFi) interface Operating system Windows 7 (SP1 or higher), 8.1 or 10 Note: Both UTF-8 and Unicode will be sup- ported, except for host names and names of units; the DNS standard will not support Unicode for them. Mac OS X 10.11.6, 10.12.6 or 10.13 Note: Intel architecture only; PPC architecture will not be supported. Windows is a registered trademark of Microsoft Corpora- tion in the USA and other countries.

7.2 Configuration of the unit

with the Dante Controller

Wait for the signal converter DADC-144DT and the units to which it is to be connected to appear in the matrix. Note: If the signal converter DADC-144DT or a connection partner fails to appear in the list, the reason may be that the unit – has not been switched on, – is in a different subnet, – is not able to synchronize with the other Dante units.However, if one of the two last-mentioned reasons applies, the Dante unit should at least appear under the tab “Device Info” or “Clock Status” in the net-work view. A fast solution of this problem may be to switch the unit off and on or to disconnect and re-establish the connection to the network switch. For further information please refer to the user manual of the Dante Controller from Audinate.

Select “DADC-144DT” in the bar of the drop-down menu appearing beneath the menu bar.

The third bar can be used to indicate infor- mation on the unit and to make settings. Select the tab “Device Config” (see fig. 4).

6) Adjust the “Sample Rate” to the desired

connection partner or set a different com- mon sample rate for both units, if required.

In the field “Rename Device”, the name used for the unit in the Dante network can be changed (e. g. to a specific name referring to the place of installation). Click “Apply” to confirm the change.

8) Use the tab “Network Config” to change

the network settings for the Dante inter- face of DADC-144DT, if required.

7.3 Routing with the Dante Controller

To assign the input signals and output signals of the corresponding units:

Under “Routing” in the window “Network View”, click

to open the channels of the desired unit under “Dante Transmitters” and the channels of the desired connec- tion partner under “Dante Receivers” (see fig.5).

Navigate from the column of the Dante transmit channel to the line of the desired Dante receive channel and click the field at the intersection point.
