DSpark Radio Transceiver Unit
The radio transceiver unit DSpark together with the docking unit DDoc ensures reliable wireless audio
transmission.
For basic configurations the DSpark can be used autonomously offering the most common functionalities for
discussion systems. This solution offers an inexpensive first step into the wireless world of conferencing
without loosing the opportunity for future system upgrading and expansion, either wired or wireless.
The radio transmission is based on the unique intelligent adaptive narrow band protocol (APRON) which
combines for the first time ever several wireless transmission security features within one single protocol
ensuring co-existence with Wi-Fi systems and resistance to mobile phones or Bluetooth emission, also
suppressing unwanted interception.
The wireless DIGIMIC provides also a multi-room solution, offering the possibility of using the same system
within one building in several rooms at the same time.
The DSpark is equipped with four independent antennas, receiving independently the individual signals of
each active microphone, providing a high audio quality and transmission reliability even under critical RF
congested environments.
The DSpark can also be wall mounted like shown in the next illustration. In this case also see HIGH POWER
in “Settings of DSpark” next chapter.

REGISTER
REGISTER can be opened (LED off) or closed (LED on).
Use REGISTER open (LED off) during setup.
During setup you switch on and register your units to the DSpark. The DSpark will automatically put all
recognized units into an internal list. This list will be expanded as long as the register function is open (LED
off).
To save this list close the Register (LED on). Once the register is closed no more units can be registered to
the DSpark. This function offers you the following opportunities:
1. The wireless system is now completely closed (like a wired one) and cannot be intercepted by any
other wireless DIGIMIC unit. This is important because to exclude interception you have to take out
the unit which are designed to work perfectly with the DIGIMIC wireless: DMic and DDoc.
2. This register function also enables to use multiple DIGIMIC wireless systems within one building by
simply assign your units to the DSpark of the corresponding room (please refer to page 26 for more
details)
Note: The list is stored automatically.
To delete the list press and hold button “register” for minimum 5 seconds. The corresponding LED
will flash two times to indicate that the list is deleted.
Note: You can exchange the battery pack and re-register the units which had already registered
even when the register is closed.
HIGH POWER
With this option the power of sending is increased in the case DSpark is used as desktop. When DSpark is
wall mounted, there is no need of increasing the output power.
PRIOrity mode
If a DChair unit is to be used, PRIO mode is available with this setting. Press button PRIO to enable this
option. Maximum 2 DChair units are supported as chairpersons at the same time. They will be identified
automatically. With 2 DChair units 2 active Delegate units DMic are possible at the same time.
This means:
0 DChair Æmax 4 active delegates’ are possible
1 DChair Æmax 3 active delegates’ are possible
2 DChair Æmax 2 active delegates’ are possible

DDoc Docking Unit
The docking unit DDoc transforms the delegate unit DMic into a wireless discussion unit, replacing the tasks
of a cable by its powerful rechargeable battery and the reliable and stable wireless communication protocol.
DMic and DChair are delivered with a cover to protect the contact bar.
Before using the DDoc the first time we recommend to check or charge the rechargeable batteries.
(please refer to page 23)
The transformation of the wired DIGIMIC delegate units is easily be done by unplugging the cable and sliding
the DMic on the docking station DDoc.
But before sliding the DMic on the docking station, it is necessary to remove the covering of the
contact bar on the rear side. This is done in the way shown below:
1. Turn the DMic upside down, if there is no microphone plugged in. We recommend
handling on a soft surface.
2. Press the two clips in the shown direction.
3. Turn the DMic on top, the covering should fall down.
