Frequently Asked Questions - DADC144DT Monacor

What is the Dante protocol?

Dante (Digital Audio Network Through Ethernet) is a networked audio standard developed by Audinate. It allows transmission of up to 512 uncompressed audio channels with minimal latency over a standard Ethernet network.

How to connect a microphone or line source to the DADC144DT?

Connect the source to the input XLR jacks (INPUT SECTION). The inputs accept balanced signals; for an unbalanced source, connect pins 1 and 3 of the XLR plug. Activate 48V phantom power (PH.PWR switch) only if necessary and with the device off.

How to adjust the input gain?

Use a small screwdriver to adjust the INPUT GAIN potentiometers (2). Turn left to reduce sensitivity. The SIG LED (1) should light when signal is present, and the PK LED (3) only during peaks. If PK lights continuously, reduce the gain.

How to use the MUTE function?

Each output has a MUTE switch (8). When pressed, the corresponding output sound is muted; when released, sound is restored.

How to configure the Dante network?

Download and install the Dante Controller software from Audinate. Connect the device to the network, launch Dante Controller, select the DADC144DT in the Device view, then perform channel routing (Transmitters to Receivers) in the Routing tab.

What is the function of the LEDs on the front panel?

SIG LED (input): signal present; PK LED: clipping. LINK LED: network connection; ACT LED: network activity. SIG LED (output): output signal; ON LED: device powered on.

Can I use unbalanced XLR cables?

Yes, by connecting pins 1 and 3 of the XLR plug. However, when phantom power is active, never connect a microphone or unbalanced device; this could damage it.

What to do if the device does not power on?

Check the power cord and outlet. If the fuse has blown, replace it with a fuse of the same type (see fuse holder on the rear). If the problem persists, contact a qualified technician.

How to clean the device?

Use a dry, soft cloth. Never use chemicals, alcohol, or water. Disconnect the device before cleaning.

What are the important safety precautions?

Never open the casing (dangerous voltage). Use only indoors, away from liquids and moisture. Disconnect immediately if visible damage or malfunction occurs. Repairs must be carried out by a professional.

3 Applications

This signal converter is used as an interface between analog audio units and a Dante audio network. 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 outputs 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.

3.1 Dante

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 software 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 Audinate, it is also possible to use computers as signal sources and thus to feed audio files replayed 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 provides four transmitter channels (the signals of the analog inputs) and four receiver channels (the signals to the analog outputs). The transmitters and the receivers are assigned in the Dante network via the Dante configuration program "Dante Controller" ( chapter 7).

The Ethernet interface is also configured via the program "Dante Controller" ( chapter 7.2). For correct configuration, knowledge in network technology is indispensable.

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.

5.1 Inputs

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 contacts 1 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 supply 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.

5.2 Outputs

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 provide balanced signals.

5.3 Network

For connection to a Dante network, connect the RJ45 jack NETWORK (14) to an Ethernet switch which supports at least Fast Ethernet (100 MBits/s Ethernet).

The LED indicator LINK (4) will light up when a network connection has been established; the LED indicator ACT (5) will light up to indicate network activity.

5.4 Power supply

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

6 Operation

1) Prior to initial switch-on, use a small screw-driver to set the controls for sensitivity adjustment INPUT GAIN (2) and the controls OUTPUT LEVEL (7) to the left stop.
2) First switch on the signal sources connected 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 continuously when the input is overloaded. In this case, reduce the input sensitivity or the level of the signal source accordingly.
4) 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.
5) Use the switches MUTE (8) to mute the corresponding outputs (engage the button). To unmute an output, disengage the corresponding button.
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 Dante Network

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 website 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
