Signal Converter for Dante
Audio Networks
These instructions are intended for installers
with knowledge in network technology. Please
read the instructions carefully prior to operation
and keep them for later reference.

1 Applications

This signal converter is mainly designed to feed
analog microphone or line level signals to a Dante
audio network. For this, two XLR inputs are available;
for each of these inputs, a 12 V phantom power sup-
ply can be separately activated. A 3.5 mm stereo jack
for line level signals is provided as well. In addition,
the DTTA-2 features two Dante reception channels
whose analog signals are output via a 3.5 mm stereo
jack; these channels can be used as monitor ways,
for example.
The signal converter can be supplied with power
via the network (via PoE) or by means of an additional
power supply unit.
1.1 Dante
Dante, an audio network developed by the compa-
ny Audinate, allows transmission of up to 512 audio
channels at the same time. Dante (Digital Audio Net-
work 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-effec-
tive 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 transmit-
ters are used as signal sources. Units configured as
receivers receive the signals from the Dante network.
Some units, such as the DTTA-2, provide transmitting
channels and reception channels.
The transmitting channels and reception chan-
nels are assigned in the Dante network via the
Dante configuration program "Dante Controller"
☞
( chapter 6).
The Ethernet interface is also configured via the
☞
program "Dante Controller" (
correct configuration, knowledge in network tech-
nology is indispensable.

2 Important Notes
The unit corresponds to all relevant directives of the
EU is therefore marked with
•
The unit is suitable for indoor use only. Protect it
against dripping water, splash water and high air
humidity. The admissible ambient temperature
range is 0 – 40 °C.
•
For cleaning only use a dry, soft cloth; never use
water or chemicals.
•
No guarantee claims for the unit and no liability for
any resulting personal damage or material damage
will be accepted if the unit is used for other pur-
poses than originally intended, if it is not correctly
connected or operated, or if it is not repaired in an
expert way.
If the unit is to be put out of operation defi-
nitively, take it to a local recycling plant for a
disposal which is not harmful to the environ-
ment.

3 Installation and Connection

If required, install the converter at a suitable place,
using its mounting brackets (3).
1) Connect the analog signal sources to the XLR jacks
MIC / LINE IN (7). Microphones or audio sources
with line level may be connected. The jacks are
designed for balanced signals.
If a microphone or audio source requires phantom
power supply (e. g. electret microphones), engage
the corresponding switch S1/ S2 (5).
Caution:
1. To prevent loud switching noise, actuate the
switch only when the DTTA-2 is not connected
to the audio network.
2. When the phantom power supply has been ac-
tivated, do not connect any microphone with
unbalanced signal output; it may be damaged.
2) As an alternative to the inputs MIC / LINE IN (7),
audio sources with unbalanced line level signals
can be connected to the 3.5 mm stereo jack AUX
IN (9). The gain for this input cannot be adjusted.
Note: When the XLR jack and the 3.5 mm jack are used,
the input signals of a channel will be mixed.

4) For connection to a Dante network, connect the
RJ45 jack (1) to an Ethernet switch which will sup-
port at least Fast Ethernet (100 Mbits /s Ethernet).
This connection will also supply the converter with
power via the network (e. g. via a network switch
with PoE power supply).
5) When power is not supplied via the network,
connect a regulated 12 V DC power supply unit
with a permanent rating of 500 mA (e. g. PSS-
1205DC) to the jack DC (2), using a DC power
connector with a dimension of 5.5 / 2.1 mm
(outside/inside diameter). Observe the polarity:
inside contact = +
4 Operation
The DTTA-2 will switch on as soon as it is supplied
with power (via power supply unit or PoE). The LEDs
(4) will indicate the status:
DC: power supply via the jack DC
PoE: power supply via the network
Link: data connection to the network
1) Use the controls
◢
to the type of the signal source in such a way that
the peak indicator in the LED strip (6) of the cor-
responding input channel will light up with signal
peaks only.
2) Use the program "Dante Controller" to include
the converter into a Dante network (
ter 6).
