7 Power switch
8 BNC jacks for the two antennas (4) provided
9 For each receiver unit: audio output (XLR,
balanced) for connection to an input with
line signal level or, when level attenuation is
activated, to a microphone input
10 For each receiver unit: audio output (6 3 mm
jack, unbalanced) for connection to an input
with line signal level
When the selector switch "Mixed" (11) is in
the position ON, the mixed signal of both
receiver units will be output at the jack RX1
11 Selector switch for the output signal of the
adjacent 6 3 mm jack
OFF: signal from receiver unit 1
ON: mixed signal from both receiver units
12 Strain relief for the cable of the power supply
unit
13 Power supply jack to connect the power sup-
ply unit provided

2 Safety Notes

The units (receiver and power supply unit) corre-
spond to all relevant directives of the EU and are
therefore marked with
WARNING The power supply unit uses dan-
gerous mains voltage Leave ser-
vicing to skilled personnel Inex-
pert handling may result in electric
shock
•
The units are suitable for indoor use only Pro-
tect them against dripping water, splash water
and high air humidity The admissible ambient
temperature range is 0 – 40 °C
•
Immediately disconnect the power supply unit
from the mains socket if
1 the receiver or the power supply unit is visibly
damaged,
2 a defect might have occurred after the unit
was dropped or suffered a similar accident,
3 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
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 definitely, dispose of the units in
accordance with local regulations

3 Applications

Combined with two transmitters RU-850... / 5
from JTS (wireless hand-held microphone or
pocket transmitter with a microphone connected:
☞
chapter 3 1), this receiver creates a two-chan-
nel wireless system for audio transmission which
is ideally suited for vocal sound and speech ap-
plications (e g for performances on stage or
presentations) The receiver features two identi-
cal receiver units which are operated separately
Both receiver units use "Diversity" technology:
The signal sent from the transmitter is received
by two antennas placed at a distance from each
other and checked for its quality The signal of
the highest quality is then used The transmission
range depends on local conditions; in open-field
conditions, the minimum range is 100 m
The transmission system operates in the UHF
range 506 – 542 MHz It is possible to set the
radio frequency for each receiver unit directly (in
frequency steps of 25 kHz) or to select it from
a group of frequencies; 6 groups with different
numbers of predefined channels (frequencies) are
available An overview of the groups and channels
can be found in chapter 9 1 By means of the
REMOSET ULTRASONIC function (
transmitter and the receiver unit can be synchro-
nized in a most convenient manner: The settings
for the transmitter are made on the receiver unit
and then transferred to the transmitter via an
ultrasonic signal
