2 Safety Notes
The units (receiver and power supply unit) cor-
respond to all relevant directives of the EU and
are therefore marked with
WARNING The power supply unit uses dan-
•
The units are suitable for indoor use only .
Protect them against dripping water and
splash water, high air humidity and heat
(admissible ambient temperature range:
0 – 40 °C) .
•
Do not operate the receiver and immediately
disconnect the power supply unit from the
socket
1 . if the units are visibly damaged,
2 . if a defect might have occurred after a
unit was dropped or suffered a similar
accident,
3 . if malfunctions occur .
In any case the units must be repaired by
skilled personnel .
•
For cleaning only use a dry, soft cloth; never
use water or chemicals .
•
No guarantee claims for the units and no
liability for any resulting personal damage or
material damage will be accepted if the units
are used for other purposes than originally
or
B
to show
intended, if they are not correctly connected
or operated, or if they are not repaired in an
expert way .
If the units are to be put out of oper-
ation definitively, take them to a local
recycling plant for a disposal which is
not harmful to the environment .
.
gerous mains voltage . Leave ser-
vicing to skilled personnel only .
Inexpert handling of the unit
may result in electric shock .
3 Applications
Combined with two transmitters of the TXS-
865 series from IMG STAGELINE, the multi-
frequency receiver TXS-865 creates a two-
channel wireless audio transmission system
ideally suited for professional stage applica-
tions . Both receiver units of the TXS-865 use
the diversity technology: The signal transmitted
is received by two antennas placed at a dis-
tance from each other and then checked for
its quality . The signal with the highest signal
quality will be used .
The transmission system operates in the
UHF range 506 – 542 MHz . Six channel groups
with preset channels in different numbers
(22 max .) are available . Frequency matching is
very easy: Via a radio signal, the receiver unit
will set the transmitter to the same transmis-
sion frequency (REMOSET function) .
3.1 Conformity and approval
Herewith, MONACOR INTERNATIONAL declare
that the receiver TXS-865 complies with the
directive 2014/53/EU . The EU declaration of
conformity is available on the Internet:
www .imagestageline .com
The receiver may be operated in the following
countries:
DE
The corresponding transmitters require regis-
tration; please refer to the instruction manuals
of the transmitters!
4 Rack Installation
Either use the receiver as a desktop unit or
install it into a rack for units with a width of
482 mm (19") . For rack installation, unscrew
the four feet . Fasten the two mounting brack-
ets (5) provided via two screws each to the left
and right sides of the receiver .
5 Connection
1) Insert the two antennas (1) provided into
the antenna jacks ANT . 1 and ANT . 2 (17) .
Place the antennas in a vertical position .
Hint: The pair of antenna signal amplifiers TXS-
875B (available as an accessory) can be used to
increase the transmission range and the interfer-
ence resistance . The amplifiers are supplied with
power via the antenna jacks of the receiver .
2) To connect the subsequent unit, e . g . mixer
or amplifier, the following audio outputs
are available:
AF OUTPUT BAL . (11)
balanced XLR outputs, one each for the
signal of the receiver unit CH 1 and the
signal of the receiver unit CH 2, for con-
nection to a microphone input or highly
sensitive line input
AF OUTPUT MIXED / BAL . (14)
balanced 6 .3 mm output jack for the
mixed signal of the two receiver units,
for connection to a microphone input or
a highly sensitive line input;
for connection to an unbalanced input,
use the cable provided
3) Connect the power supply unit provided to
the power supply jack (16) and to a mains
socket (230 V/ 50 Hz) .
