5 Connection
1) Insert the two antennas (4) provided into the
BNC jacks ANT 1 and ANT 2 (10) and put them
in a vertical position .
Hint: The pair of signal amplifiers TXS-875B (availa-
ble as an accessory) can be used to increase the trans-
mission range and the interference resistance . The
antenna jacks of the receiver supply the amplifiers
with power .
2) For connection to the subsequent unit (e . g .
mixer, amplifier), the following audio outputs
can be used:
– bal . XLR outputs CH 1 and CH 2 (11) for
the output signals of the individual re-
ceiver units, for connection to a balanced
microphone input
– unbal . 6 .3 mm jack MIXED OUT (8) for the
mixed signal of the two receiver units, for
connection to a line input (a matching con-
nection cable is provided)
3) Connect the power supply unit provided to the
power supply jack 12 V ⎓ (9) and to a mains
socket (230 V/ 50 Hz) .
6 Operation
Switch on the receiver with the switch POWER
(3) . The display (7) shows the channel indications
(f) of the transmission channels adjusted for the
two receiver units . As long as a receiver unit does
not receive a radio signal of sufficient strength, it
is muted [symbol (g) is displayed] .
Make the following adjustments separately for
each receiver unit .
1) Switch on the transmitter . If the channel in-
dication (f) displays a different channel than
the one adjusted on the transmitter, adjust the
receiver unit to the channel of the transmitter:
☞ chapter 6 .1 .
If the transmitter and the receiver unit
have been adjusted to the same transmission
channel and if the strength of the radio signal
received is sufficient, muting is deactivated
[symbol (g) disappears] . One of the indica-
tions or (e) lights up to indicate which of
A B
the two antennas receives the radio signal of
higher strength . The bar graph RF (c) indicates
the reception quality: the more segments are
displayed, the better the reception .
If the reception is poor or disturbed, please
check if
– the reception can be improved by using a
different transmission channel .
– the batteries of the transmitter are not suffi-
ciently charged any more (see battery status
indication on the transmitter) .
– the distance between the transmitter and
the receiver is too long .
– the reception is disturbed by objects in the
transmission path .
– the reception can be improved by turning
the antennas .

– the squelch adjusted with the control
SQUELCH (12) is too high (
2) Switch on the subsequent audio unit or ad-
vance the corresponding control on the mixer .
3) Speak / sing into the microphone and use the
the volume control (5) to match the output
level of the receiver unit to the input of the
subsequent unit .
The bar graph AF (d) on the display shows
the volume of the audio signal received: the
more segments are displayed, the higher the
volume level . Adjust the optimum volume on
the transmitter ( ☞
transmitter) .
4) Use the control SQUELCH (12) – CHANNEL 1 for
receiver unit 1, CHANNEL 2 for receiver unit 2 –
to define the threshold value for the squelch .
The further the control is turned clockwise,
the higher the threshold value .
The squelch will mute the receiver unit,
if, during music intervals, high-frequency in-
terference signals are received whose levels
are below the threshold value adjusted . With
a higher threshold value, however, the trans-
mission range will be reduced as the receiver
unit will also be muted if the strength of the
radio signal of the transmitter falls below
the threshold value adjusted . Thus, a higher
threshold value may be adjusted if the recep-
tion is good . However, with a longer distance
between the transmitter and the receiver, a
lower value should be selected .
After operation, switch off the receiver with the
switch POWER (3) . If the receiver is not used for
a longer period of time, disconnect the power
supply unit from the mains socket as it will still
consume some power when the receiver has
been switched off .
6.1 Adjusting the transmission channel
1) In the control panel of the receiver unit, press
the key  or  (6) [for a minimum of 1 s] . On
the display, the indication (b) for the channel
adjusting mode starts flashing: RX1 (for receiver
unit 1) or RX2 (for receiver unit 2) .
2) As long as the indication keeps flashing, the
channel can be selected: With the key  , the
channels are scanned in ascending order;
with the key , they are scanned in descend-
ing order . The 16 channels are assigned to the
following receiving frequencies:
Channel Frequency
1 518 .750 MHz
2 519 .375 MHz
3 521 .125 MHz
4 522 .000 MHz
5 523 .250 MHz
6 524 .250 MHz
7 524 .875 MHz
8 526 .000 MHz
3) Approx . 3 seconds after the last actuation of
a key, the indication RX1 or RX2 will disap-

Note: It is not possible to set both receiver units to
the same channel . The channel selected for the first
receiver unit will be automatically skipped during chan-
nel adjustment for the second receiver unit .

6.1.1 Lock mode

To prevent accidental change of the transmission
channels selected, it is possible to activate the
lock mode . With the lock mode activated, it is not
possible to call up the channel adjusting mode
