F indication "MUTE"; to indicate muting
of the audio outputs when settings are
made via the buttons SET,
(5) or when the button POWER (2) is
pressed
G indication of radio frequency
H bargraph "RF" (radio frequency) for the
strength of the radio signal received
I bargraph "AF" (audio frequency) for

2 Safety Notes

The units (receiver and power supply unit)
correspond to all relevant directives of the EU
and are therefore marked with

•
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) .
•
Immediately disconnect the power supply
unit from the mains socket
1 . if the receiver or the power supply unit
is 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
and
skilled personnel .

3 Applications
Combined with two transmitters of the
TXS­900 series from IMG STAGELINE (wireless
microphone TXS­900HT or pocket transmitter
TXS­900HSE with a microphone connected),
the 2­channel multifrequency receiver
TXS­920 can be used to set up two wireless
audio transmission systems, e . g . for stage
applications . The receiver uses "True Diver­
sity" technology and operates in the two UHF
ranges 823 – 832 MHz and 863 – 865 MHz .
The two identical sections of the receiver
are operated separately . For each receiver
section, there are 3 operating modes to set
the transmission channel: manual setting,
channel scan or selection from one of 4 pre­
set groups (8 channels in each group) . The
receiver section and the transmitter are syn­
chronized by radio transmission: When the
synchronization button is kept pressed on the
transmitter and the button SYNC is briefly
pressed on the receiver section at the same
time, the transmitter is set to the transmission
channel of the receiver section .

3.1 Conformity and approval

Herewith, MONACOR INTERNATIONAL de­
clare that the receiver TXS­920 complies with
the directive 1999 / 5 / EC . The EU declaration
of conformity is available on request from
MONACOR INTERNATIONAL . The re ceiver
is generally approved for operation in EU
and EFTA countries; it is licence-free and
requires no registration.
4 Setting up /
Installation into a Rack
The receiver can be placed on a table or be
installed into a rack (482 mm / 19") . For instal­
lation into a rack, use three screws each to
fasten the two rack brackets provided to the
left and right sides of the receiver .
For optimum reception, make sure that
there are no obstacles between the transmit­
ters and the receiver . Do not position the units
in the immediate vicinity of any large metal
surfaces or digital devices (e . g . CD players,
computers) .
