of what to use but rather how to use it best. The wired system is upgraded to a wireless system by simply
adding the wireless docking unit whenever needed. It is a simple and elegant solution for both rental and
sales applications.
Simple, versatile, DIGIMIC!
The digital conference system provides a 100% stand alone solution and is completely self-configuring. With
DIGIMIC it is easier then ever before to setup even the most complex conference systems. True plug (and /
or unplugged) and play setup ensures that any microphone unit is operational instantly when connected.
DIGIMIC matches digital broadcast and studio audio requirements, meeting the needs of today’s
conferencing world. At any time the system can be expanded to include our conference software. TCP/ IP
communication is utilized to offer microphone control and name handling as well as other conference
requirements.
The delegate’s frontend – the microphone unit – offers a thoughtful ergonomic design enabling the delegate
to concentrate on the conference.

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:

LS INTERN). The current radio channel number is displayed.
The pattern of the LEDs is shown in the table below:

Now the user can specify the new logical radio number by setting the LEDs with the corresponding buttons
on or off. It is insignificant which LEDs are switched, or in what order this happens. Only the number of LEDs
lucent is relevant as input for the new radio system number.
Examples for valid input of radio system number 2:

Five seconds after pressing any button the configuration mode is finished. This is indicated by blinking two
times of all 4 LEDs (REGISTER + HIGH POWER + PRIO + LS INTERN). The new radio system number is
now saved will be used until this setting is changed again.
Also the primary status of the LEDs and the function of the buttons are restored. The new settings are
immediately effective; there is no need to switch DSpark on and off.
If no changes are made in configuration modus the current setting persists when leaving the configuration.
Therefore this procedure can be used to show the current setting of the radio system number.

Multi room operation
Adjusting DMic/DDoc combination to a room (0 – 4)
Please make sure only one DSpark in your venue has activated the register function (register open –
LED OFF).
Please make sure that the preset of the several DSpark Radio Transceiver Units is like described above.
Open Register (LED OFF) on your first DSpark (Local radio channel number 0). Make sure other DSpark
have their Register closed (LED on). Place the desired number of units on the table and press the MIC
button one after each other.
Resetting of DDoc Docking Units
DSpark can reset all docking stations DDoc which are allocated to this DSpark (Radio Transceiver Unit) and
are in operating distance. Therefore press the inner buttons HIGH POWER and PRIO simultaneously for
about 5 seconds. The LEDs of HIGH POWER and PRIO are flashing for the time of deleting, but minimum
three times.
If you do this, all DDoc units will forget the room number they were tied to. This requires a new setup.
Allocation of DDoc Docking Units
To configure the DDoc units press and hold the MIC button for at least 4 seconds. This procedure is
indicated by flashing of the multi MIC-LED. The current radio channel number is reset. In this mode DDoc
searches for any DSpark Radio Transceiver Units. If one is recognized DDoc tries to log in. When successful
DDoc gets confirmation and stores the new radio channel number as default.
This will finish the configuration mode.
If there is no log-in possible DDoc will terminate the configuration mode after 30 seconds and then switch off.
When all microphones are working (successful login) a quick microphone test is recommended. Close the
Register (LED ON). After this you can go to the second room and perform the same procedure with a
DSpark assigned to the next room (local radio number 1).
