Microphone Array
for Dante Audio Networks
These instructions are intended for install-
ers of audio systems with knowledge of
network technology. Please read the in-
structions carefully prior to operation and
keep them for later reference.
1 Applications
This desktop microphone is specially designed
for audio systems based on Dante audio net-
works. It consists of an array of 17 electret
capsules. In contrast to a conventional micro-
phone, this results in a particular directionality
allowing excellent speech intelligibility even
when the person speaking is at a greater dis-
tance from EAM-17DT (≈ 80 cm), when the
person speaking is moving sideways or when
the persons speaking do not have the same
height. This desktop microphone is ideally suit-
ed for lectures, discussions, announcements
and video conferences.
A configuration software for computers
with Windows operating system can be used
to set the desired gain, to activate an impact
noise filter and to define the operating mode
of the talk button.
An LED will indicate the operating status of
the microphone via its colour. The microphone
is supplied with power via the network using
PoE (Power over Ethernet).

ration in the United States and other countries.
1.1 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 synchro-
nised, with minimum latency. The advantage
over analogue audio signal transmission is a
cost-effective connection of components via
standard network cables and low susceptibility
to interference, even in case of long transmis-
sion paths. In addition, signal routing between
components that have once been connected
can be changed by software at any time. In
the Dante network, signal sources act as trans-
mitters and pass on their signals to receivers.
The program "Dante Virtual Soundcard" from
Audinate also allows computers to be used as
1 2
➀
signal sources, and signals from the Dante net-
work can be recorded on the computer.
Even if the audio signal of the microphone
is monophonic, EAM-17DT offers two trans-
mission channels that can be connected in-
dependently in the Dante network. The trans-
mission channels are assigned to any receiving
channels in the Dante network via the config-
uration program "Dante Controller" (
ter 4).

3 Connection to a Dante Network
To integrate the microphone into a Dante
network, knowledge of network technology
is essential.
Use a Cat-5 or Cat-6 cable to connect the
RJ45 connector (3) of EAM-17DT to an Ether-
net switch that supports at least Fast Ethernet
(transmission rate 100 Mbit /s) and supplies PoE
(Power over Ethernet according to the standard
IEEE 802.3af-2003). The cable can be guided
out to the rear through the cable hole (4).
The interface of EAM-17DT is preset for au-
tomatic address assignment and can be con-
figured via the program "Dante Controller"
☞
( chapter 4.1).

4 Setting up the Dante Network
EAM-17DT is configured as a transmitter in
the Dante network by means of the program
"Dante Controller", available as a free down-
load on the Audinate website. The settings
made via the program will be saved in the
corresponding transmitters and receivers of
☞
the Dante network so that the program is only
chap-
required for network configuration but not for
normal operation.
Download and install the program "Dante
Controller" via the following Internet address
on the computer on which the program is to
be executed:
.

4.1 Device configuration with the
Dante Controller
1) Start the Dante Controller.
2) Wait until the desired Dante receiver and
EAM-17DT (under "Transmitters") appear in
the matrix.
Note: If EAM-17DT or a connection partner does not
appear, the reason may be that the corresponding
device
– is not switched on,
– is in a different subnet,
– is not able to synchronise with the other Dante
devices.
However, for one of the latter two reasons, the Dante
device should at least be listed under the tab "De-
vice Info" or "Clock Status" in the "Network View"
window. To solve the problem quickly, it may help
to turn the device off and on again or to disconnect
and reconnect the LAN. For more information, refer
to the Audinate user manual for the Dante Controller.
3) In the menu bar of the Dante Controller, se-
lect "Device / Device View" or use the short-
cut Ctrl + D. The "Device View" window will
appear.

4) Select EAM-17DT from the drop-down

menu appearing in the bar underneath the
menu bar.
5) In the third bar, various information about
the device can be displayed and settings can
be made. Select the tab "Device Config"
