ENGLISH
These instructions are intended for users of
short-distance wireless audio systems (e. g. in-
ear monitoring systems, wireless microphone
systems). Please read the instructions carefully
prior to operation and keep them for later ref-
erence.
1 Applications
There are two ways to use the antenna combiner
UC-900:
1. The signals of up to four transmitters can be
sent via one antenna (fig. 1).
2. To extend the reception range of a receiver,
the signals of up to four antennas placed at
a corresponding distance can be combined
(fig. 2).
In addition, the UC-900 is able to supply four
units with a ⎓ 12 V operating voltage (1 A max.
each).
2 Safety Notes
The unit corresponds to all relevant directives of
the EU and is therefore marked with
WARNING The unit uses dangerous mains
voltage. Leave servicing to skilled
personnel only and do not insert
anything into the air vents! Inex-
pert handling may result in elec-
tric shock.
•
The unit is suitable for indoor use only. Protect
it against dripping water and splash water,
high air humidity and heat (admissible ambient
temperature range: 0 – 40 °C).
•
Do not place any vessel filled with liquid on the
unit, e. g. a drinking glass.
•
The heat produced inside the unit must be
dissipated by air circulation; therefore, never
cover the air vents of the housing.

•
Immediately disconnect the mains plug from
the socket
1. if the unit or the mains cable is visibly dam-
aged,
2. if a defect might have occurred after the
unit was dropped or suffered a similar
accident,
3. if malfunctions occur.
In any case the unit must be repaired by skilled
personnel.
•
Never pull the mains cable to disconnect the
mains plug from the socket, always seize the
plug.
•
For cleaning only use a dry, soft cloth; never
use water or chemicals.
•
No guarantee claims for the unit and no liabil-
ity for any resulting personal damage or mate-
rial damage will be accepted if the unit is used
for other purposes than originally intended, if
it is not correctly connected or if it is not re-
paired in an expert way.
.
3 Operation
1) To send the signals* of up to four transmit-
ters via one antenna, connect the transmit-
ting antenna to the jack "Antenna Output"
and connect the transmitters to the jack "RF
Input" (fig. 1).
or
To send the signals* of up to four antennas to
one receiver, connect the receiving antennas
to the jacks "RF Input" and the antenna jack
of the receiver to the jack "Antenna Output"
(fig. 2).

2) If the units connected require a ⎓ 12 V oper-
ating voltage (1 A max.), it will be possible to
supply them with power via one of the jacks
DC OUTPUT (see dashed line in fig. 2).
3) Connect the mains jack of the UC-900 to a
socket (230 V/ 50 Hz) via the mains cable pro-
vided. Switch on the UC-900 and all units
connected.
The green LEDs CH1 ... CH4 light up as
soon as signals of sufficient power (> +5 dBm)
are present at the jacks "RF Input". However,
the signals of receiving antennas are too weak.
