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 danger-
ous mains voltage . Leave servicing
to skilled personnel only . Inexpert
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
1 . if the receiver or the power supply unit is vis-
ibly 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 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 operation
definitively, take them to a local recycling
plant for a disposal which is not harmful
to the environment .

3 Applications

Combined with a transmitter of the TXS-1800
series (wireless microphone TXS-1800HT or pocket
transmitter TXS-1800HSE), this multifrequency
receiver TXS-1800 can be used to set up a wireless
audio transmission system, e . g . for stage applica-
tions . The receiver uses "True Diversity" technol-
ogy: The signal sent is received by two antennas
and amplified in two separate receiver sections .
The signal of the highest reception quality is then
processed .
The TXS-1800 system operates in the UHF
range 1785 – 1800 MHz (16 channel groups of
12 channels each) . A most convenient feature is
the frequency synchronization: At the press of a
10
.
button the transmitter will be matched to the radio
frequency of the receiver by IR signal . Transmission
power and gain of the transmitter can be set on
the receiver; these data will also be transferred to
the transmitter during IR transmission .

3.1 Conformity and approval

Herewith, MONACOR INTERNATIONAL declare that
the receiver TXS-1800 complies with the directive
2014 / 53 / EU . The EU declaration of conformity is
available on the Internet:
www .img-stageline .com
Restrictions or requirements apply in the fol-
lowing countries:
CZ UK
4 Setting up and Connection
For optimum reception, place the receiver at least
1 m above the ground, not too close to adjacent
walls . Make sure that there are no obstacles be-
tween the transmitter and the receiver . Do not posi-
tion the units in the immediate vicinity of metal sur-
faces or digital devices (e . g . CD player, computer) .
1) Connect the receiving antennas provided (1) to
the antenna jacks (9) and put them upright in a
V-shaped position .
2) For connection to a microphone input or to a
highly sensitive line input of the subsequent unit
(e . g . mixer, amplifier), use one of the two audio
outputs (8):
– balanced XLR output
(phantom power resistant)
– unbalanced 6 .3 mm output jack;
matching connection cable is supplied
When the units are placed far apart, the XLR
output should be preferred . The balanced signal
transmission offers higher protection against
interference which may occur especially with
long cables .
3) For power supply, connect the power supply unit
provided to the power supply jack (7) and to a
mains socket (230 V/ 50 Hz) .
4.1 Installation into a rack
For installation into a rack (482 mm / 19"), two rack
brackets are supplied . First remove the front screw
on each side of the receiver . Now there are three
holes on each side for attaching the rack bracket .
Then use the screws supplied to fasten the rack
brackets to the sides of the receiver ( ☞ fig . 4) .
