Structure
Introduction
The DCen MkII central DIGIMIC control unit controls all connected DIGIMIC units within the DIGIMIC
system. The DCen MkII automatically configures the units and routes all audio signals exactly where
you need it. The central unit provides all common microphone modes, voting, identification, channel
selector (32 channels), chairman priority switching and VIP management. In addition, the DCen MkII
manages and controls the DDol interpreter consoles.
Via four independently operated ports, the DCen MkII can control 100 or more microphone units - in
combination with the DExt auxiliary power supply, additional units are possible. Alternatively, DDol
interpreter consoles can be connected or combined with microphone units in separate chains. As
soon as a unit is connected to the central unit, it is immediately ready for use without any further
settings.
To adapt the setup to local conditions, the DCen MkII central unit can be configured via the DCen
ConfigTool software - among other things, you can use the software to select the microphone mode
used and set the channel selector, for example. The MicControl2 software also offers you functions
such as seat-based microphone control as well as name management and speech time display -
CamControl2 puts your conference in the best possible light with optimally coordinated camera
control. The brählerOS software was developed for comprehensive control tasks and for the
management of several conference rooms.
In the default settings, the DCen MkII is ready to use without further configuration
To configure your DCen MkII, the Brähler System DCen Config Tool is mandatory. Please
read the DCen ConfigTool operating instructions.

LINE-IN
LINE-IN socket (Phoenix terminal) for feeding external signals for decentralized sound
reinforcement via the integrated loudspeakers of the microphone consoles, as well as the
original signal for the interpreters. If the signal is fed in via a mixing console and is to
come through the integrated loudspeakers, the signal must be fed back from the mixing
console. This is done via the LINE-IN socket, line level, transformer balanced.
LINE-OUT
A sum signal of all switched-on delegate units can be taken from the LINE-OUT socket
(Phoenix terminal). In the audio matrix the signal routing for this output can be changed if
required, line level, transformer balanced.
Line output jacks Out1- Out4
Audio signals are transmitted to external devices via four LINE
outputs (Phoenix terminal). For example, an external mixing
console can be connected to these jacks to perform sound
recordings or to route signals to a PA system. In the audio matrix,
the signal routing for these outputs can be changed if required.
Reset
Press and hold this button when powering on the DCen MkII until the DCen has finished
booting. This will reset the network settings to DHCP. To reset all settings to factory defaults,
use the DCenConfig tool.
If you press the button while the DCen is running, this can be displayed in
the DCenConfig tool. This helps you to identify a specific DCen.
LAN
The DCen MkII can be connected to your network via the LAN socket. This gives you the
ability to control the unit and all connected units via software. Never plug a cable from
DIGIMIC microphone consoles into this LAN jack.

USB Power
The USB output can be used to power external USB devices. The maximum power is
500mA at 5V.
The USB port is intended exclusively for power supply! The port cannot be used
as a port for USB media.
L1-L4
Four outputs (RJ45) for connecting DIGIMIC family devices - such as
microphone units, interpreter consoles or other system components (e.g.
DSwitch or DLine). The individual chains can be extended by the DExt additional
power supply for the operation of further DIGIMIC devices.
DDol interpreter consoles must not be connected in a chain together with other devices of
the DIGIMIC family. Otherwise, the functionality cannot be guaranteed.
Never connect devices other than DIGIMIC microphone or interpreter consoles to these
outputs. The operating voltage could damage other equipment.
DANTE®
Four Dante ®connectors allow audio signals of numerous channels to be
transmitted via network cable. The technology offers a relatively
interference-free transmission with low latency even over longer
distances. The Dante®connectors are also operated with 48kHz sample
rate. By default, the four Dante®ports are configured as switches.
However, using the Dante ®Controller, the mode of operation can be
switched to Primary / Secondary. In this case, only ports 4 (Primary) and
1 (Secondary) are used.

Structure
To put the DCen MkII into operation, first establish a power connection. To do this, plug the power
cord into the power connector and connect the DCen MkII to your power source. Also connect at
least one unit of the DIGIMIC family to the DCen MkII.
Now connect the individual elements that you need for your conference. All DIGIMIC components are
connected to the central unit via the L1 - L4 sockets. Use suitable shielded CAT5e cables and RJ45
plugs.
DDol interpreter consoles must not be connected in a chain with other DIGIMIC devices. The
exception is the DExt auxiliary power supply.
When the DCen MkII is switched on for the first time, it starts with default factory settings (see table
on page 17). The DCen MkII is therefore immediately ready for use with the most common settings.
All settings made are automatically saved and recalled the next time the unit is switched on.
At least one connection must be
made between the DIGIMIC
unit and the DCen MkII.

Operation
Press the on/off switch of the DCen MkII to switch on the central unit. The system will power up. All
4 green line LEDs should light up indicating correct voltage at the outputs. If this is not the case, turn
off the DCen immediately and check the wiring for shorts. During boot-up, the 4 signal LEDs on the
front panel will illuminate in sequence before extinguishing. During the boot process, the power LED
oscillates slowly. After approx. 35 seconds the boot process is completed, the power LED is
constantly on, if necessary the network LED indicates connection or data traffic. (see also from page
9 of this manual).
The DCen MkII is ready for immediate use in the factory settings. Individual settings can be made
using the DCen ConfigTool software. All configurations are automatically saved by the DCen MkII and
automatically recalled the next time it is switched on. The DCen MkII is therefore ready for use after
the first configuration (in these settings) even without a computer.
Alternatively, some settings can also be made via the BrählerOS software. However, there
are exceptions, such as audio routing, these settings can only be realized by means of
DCenConfigTool.
Reset to DHCP
If your DCen MkII is assigned to a fixed IP address and this is not available on the network,
you have the option to manually set the DCen MkII to DHCP. To do this, press and hold the
"Reset to DHCP" button on the back of your DCen MkII during power up and boot. An IP
address will then be assigned automatically via DHCP.
If no DHCP server is available, your DCen is automatically set to a private IP address of the form
169.254.X.Y. X and Y are derived from the serial number of your DCen MKII.
256 * X + Y = serial number of the DCen MkII
