3 Applications
In combination with a wireless microphone, the
multi frequency receiver TXS-871 makes up a
wireless audio transmission system which is ide-
ally suited for musicians and live performance on
stage . The wireless transmission of music or speech
to the audio system ensures the musician’s freedom
of movement during the performance .
The True Diversity* receiver operates in the UHF
frequency range of 863 to 865 MHz . Within this
range, the audio transmission frequency can be
selected from 15 frequencies (frequency spacing
125 kHz) .
The following transmitters from the product range
of IMG STAGELINE can be used:
– TXS-871HT (order no . 25 .3610)
Hand-held microphone with integrated multifre-
quency transmitter
– TXS-871HSE (order no . 25 .3620)
Multifrequency pocket transmitter, suitable for
connecting a headband microphone or a tie-clip
microphone
*
True Diversity
: 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 .
3.1 Approval of the receiver
Herewith, MONACOR INTERNATIONAL declare that
the receiver TXS-871 complies with the directive
2014 / 53 / EU . The EU declaration of conformity
is available on request from MONACOR INTER-
NATIONAL . The receiver is generally approved for
operation in EU and EFTA countries .
3.2 Rack mounting
To insert the receiver into a rack designed for units
with a width of 482 mm, use the holder RCB-870
(order no . 24 .2830) which is available as an ac-
cessory . The holder supports up to two receivers
and requires a height of 1 rack space (= 44 .5 mm) .
4 Connection
1) Insert the two supplied antennas (6) into the
BNC antenna jacks ANT . 1 and ANT . 2 (11) and
put them in a vertical position .
Hint:
To increase the transmission range and the inter-
ference resistance, it is possible to use the pair of an-
tenna signal amplifiers TXS-875B (order no . 15 .0840)
available as an accessory . The amplifiers are supplied
with power via the antenna jacks of the receiver .
2) For connecting the subsequent unit (e . g . mixer)
the receiver is provided with two audio outputs:
– AF OUT . BAL . (10)
balanced XLR output for con necting a bal-
anced microphone input
– AF OUT . UNBAL . (9)
unbalanced 6 .3 mm output jack, for connect-
ing a line input (a matching connection cable
is supplied with the unit)
If the subsequent unit is provided with a bal-
anced microphone input, the XLR output should
be used for an optimum signal transmission .
Make the corresponding connection to the
subsequent unit . Do not switch on the subse-
quent unit or do not advance the corresponding
fader on the mixer before the microphone sys-
tem has completely been switched on .
3) For power supply, connect the power supply
unit provided to the power supply jack (8) and
to a mains socket (230 V/ 50 Hz) .
