1 Overview

1.1 Front panel

1 LED indicator SIG, will light up when a
signal is available at the corresponding
input CH 1 to CH 4
2 Control to adjust the sensitivity of the
corresponding input CH 1 to CH 4
3 LED indicator PK, will light up when the
maximum input level allowed of the cor-
responding input CH 1 to CH 4 has been
reached or exceeded
When the LED indicator lights up fre-
quently, reduce the input gain by means
of the corresponding control (2) .
4 LED indicator LINK, will light up when a
network connection has been established
5 LED indicator ACT, will light up to indicate
network activity
6 LED indicator SIG, will light up when a
signal is available at the corresponding
output CH 1 to CH 4
7 Control to adjust the level for the corre-
sponding output CH 1 to CH 4
8 Switch MUTE to mute the corresponding
output CH 1 to CH 4
9 Power indicator ON, will light up as soon
as the outputs have been switched on
10 POWER switch

12 Mains jack for connection to a mains
socket (230 V/ 50 Hz) by means of the
mains cable supplied
13 XLR output, one each for channels CH 1
to CH 4
14 RJ45 jack for network connection
15 XLR input, one each for channels CH 1 to
CH 4, to connect microphones or audio
sources with line level
Caution! When the phantom power
supply is activated [corresponding
switch (16) engaged], the jack will be
supplied with 48 V phantom power .

Safety Notes

The unit corresponds to all relevant directives
of the EU is therefore marked with
WARNING The unit uses dangerous
•
The unit is suitable for indoor use only . Pro-
tect it against dripping water, splash water
and high air humidity . The admissible ambi-
ent temperature range is 0 – 40 °C .
•
Do not place any vessel filled with liquid on
the unit, e . g . a drinking glass .
•
Do not operate the unit and immediately
disconnect it from the mains socket
1 . if the unit or the mains cable is visibly
damaged,
2 . if a defect might have occurred after the
unit was dropped or suffered a similar
accident,
3 . if malfunctions occur .
In any case the unit must be repaired by
skilled personnel .
•
Never pull the mains cable to disconnect
the mains plug from the mains socket, al-
ways seize the plug .
•
For cleaning only use a dry, soft cloth; never
use water or chemicals .
•
No guarantee claims for the unit and no li-
ability for any resulting personal damage or
material damage will be accepted if the unit
is used for other purposes than originally
intended, if it is not correctly connected
or operated, or if it is not repaired in an
expert way .

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 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 .
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 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" (
ter 7 .2) . For correct configuration, knowledge
in network technology is indispensable .
