2 Safety Notes
This unit corresponds to all relevant directives of
the EU and is therefore marked with
.
WARNING
The unit uses dangerous mains
voltage . Never make any modifi-
cation on the unit not described in
these instructions; inexpert han-
dling may result in electric shock .
•
The unit is suitable for indoor use only . Pro-
tect it against dripping water, splash water
and high air humidity . The admissible am-
bient temperature range is 0 – 40 °C .
•
Do not place any vessels filled with liquid, e . g .
drinking glasses, on the unit .
•
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 liability
for any resulting personal damage or material
damage will be accepted if the unit is used for
other purposes than originally intended, if it is
not correctly connected or operated, or if it is
not repaired in an expert way .
If the unit is to be put out of operation
definitively, take it to a local recycling
plant for a disposal which is not harmful
to the environment .
3 Applications
The antenna splitter TXS-875DS is designed for
operating up to four multifrequency receivers from
IMG STAGELINE which
– operate in a frequency range between 470 and
960 MHz
– are equipped with removable antennas (BNC
connection)
– are supplied with +12 V/1 A max .
The TXS-875DS makes it easier to set up the audio
transmission system: Only two of the antennas
supplied with each receiver (one pair for each re-
ceiver) are required for connection to the antenna
splitter; all other antennas and the power supply
units of the receivers are not required . The split-
ter will send the antenna signals to the receivers
and supply the receivers with power . Matching
connection cables are supplied .
When more than four receivers are operated,
the cascade outputs (8) can be used to connect
multiple TXS-875DS in series . Each antenna split-
ter will be able to supply four receivers with power .
The antenna splitter can also be used in connec-
tion with the antenna signal amplifiers TXS-875B
(available as a pair) . The antenna splitter will sup-
ply the amplifiers with power .
4 Operation
4.1 Preparation and setting up
1) When the antenna signal amplifiers TXS-875B
are used, the 12 V supply voltage for these
amplifiers must be available at the jacks ANT . A
and ANT . B (7) . Prior to operation, please make
sure that the corresponding switch for the sup-
ply voltage in the unit (fig . 2 on page 2) has
been set to the position ON .
WARNING
Always disconnect the mains
plug before opening the unit;
otherwise, you will risk an
electric shock .
2) To install the reception antennas on the front
panel of the TXS-875DS, insert the two BNC
jack-to-jack adapters supplied with the unit into
the mounting holes on the left and on the right
and screw them on (refer to fig . 1 on page 2) .
3) Place the antenna splitter on a flat surface
or install it into a rack for units with a width
of 482 mm (19”) . For installation into a rack,
1 rack space (= 44 .45 mm) is required .
4.2 Connection and switching on
The connection options can be found in fig . 3
on page 2 .
1) Connect the low voltage jacks DC OUTPUT (6)
to the power supply jacks of the receivers .
2) Connect the antenna pair of one of the receiv-
ers to the antenna splitter:
– either to the two jacks (1) on the front panel
of the unit; in this case, connect the rear
side (4) of these jacks to the jacks ANT . A
and ANT . B (7)
– or directly to the two jacks ANT . A and ANT . B
(7) on the rear panel of the unit .
When using the antenna signal amplifiers
TXS-875B, insert the amplifiers between the
antennas and the antenna splitter .
3) Connect the two antenna inputs of each re-
ceiver to an antenna output ANT . A 1 … 4 and
to the corresponding antenna output ANT . B
1 … 4 (9) .
4) The antenna signals can be routed to an other
TXS-875DS: Connect the outputs ANT . A
CASCADE and ANT . B CASCADE (8) to the
inputs ANT . A and ANT . B (7) of the following
TXS-875DS . This splitter in turn allows con-
nection of four receivers .
5) Finally, connect the mains cable provided to the
mains jack (5) and connect the mains plug of
the cable to a socket (230 V/ 50 Hz) .
6) To switch the antenna splitter on or off, press
the button POWER (3) . When the unit is
switched on, the power LED (2) will light up .
Notes:
1 . If the antenna splitter provides 4 receivers with
power, the switch-on current of all receivers may
be too high and the power supply unit of the splitter
will not start . In this case, briefly switch off one of
the receivers .
2 . If the
TXS-875DS
is not used for a longer period
of time, always disconnect the mains plug from
the mains socket; even when the splitter has been
switched off, it will still consume some power while
it is connected to the mains .
