Installation into a Rack
The receiver can be placed on a table or be
installed into a rack (482 mm/19"). For installa-
tion 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 transmitters 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).
5 Connecting Antennas
and an Audio Unit
5.1 Antennas
Connect the receiving antennas provided (1) to
the antenna jacks (7) and put them in a vertical
position.
When installing the receiver into a rack, the
reception may be improved when the receiving
antennas are placed at the front of the rack. For
this purpose, each rack bracket supplied is pro-
vided with a hole for installing an antenna. To
install an antenna at a rack bracket:
1) Insert a BNC adapter (2 × BNC jack, 50 Ω)
into the hole provided on the bracket and fas-
ten it.
2) Connect the antenna to the front jack of the
adapter.
3) Use a 50 Ω BNC cable to connect the rear
jack of the adapter to one of the antenna
jacks on the rear of the unit.
5.2 Audio connections
To send the signals of the two receiver sec-
tions separately to the subsequent audio unit
(e. g. mixer, amplifier), each receiver section is
provided with two outputs (10). Use one of these
two outputs of each receiver section to connect
it to a microphone input or to a line input of the
subsequent unit:
– balanced XLR output
This output should be preferred when the
units are far apart. The balanced signal trans-
mission offers a higher protection against
interference which may occur especially with
long cables.
– unbalanced 6.3 mm output (a matching con-
nection cable is provided)
Note: Never use the balanced output and the unbal-
anced output at the same time; the signal quality may
be affected.
Use the sliding switch (11) to match the output
level to the input: For connection to a line input,
set the switch to the left position LINE; for con-
nection to a microphone input, set the switch to
the right position MIC.
To send the mixed signal of the two receiver
sections to the subsequent audio unit, connect
the unbalanced 6.3 mm output jack MIX OUT (8)
to a line input of the audio unit.

6 Operation
Connect the power supply unit provided to the
power supply jack (9) and to a mains socket
(230 V~/ 50 Hz). After connection to the power
supply, the receiver is switched on.
To switch the receiver on or off, use the button
POWER (2): Keep the button pressed for
approx. 1 second.
If the receiver is not in use for a longer period of
time, disconnect the power supply unit from the
mains socket. Even when the receiver is
switched off, the power supply unit has a low
power consumption.
7 Setting the
Transmission Channel
For the two wireless transmission systems which
can be set up with this 2-channel receiver, set
the transmission channels separately on each
receiver section. Use the buttons SET,
(5) on the receiver section to make the settings.
Three operating modes are available.
When setting the channel on a receiver section,
make sure that any switched-on transmitters
of wireless systems operated at the same time
are not too close to the receiver (minimum dis-
tance: 1 m).
7.1 Selecting the operating mode
The display indicates the current operating
mode: "MANUAL", "SCAN" or "PRESET" (A). To
select the desired mode, use the button
Keep the button pressed for approx. 1 second to
go to the next mode (or keep the button pressed
until the mode is indicated, then release it).
7.2 Mode MANUAL
In the mode MANUAL, the desired radio fre-
quency can be selected manually from the 442
radio frequencies available (
1) Use the button
or
to select the mode
MANUAL (
chapter 7.1). The display will
indicate the most recent radio frequency (G)
and corresponding channel number (E)
adjusted in the mode MANUAL or SCAN.
2) To activate the setting mode, keep the button
SET pressed for approx. 1 second until the
channel indication (E) and the frequency indi-
cation (G) start flashing.
Note: When no button is pressed, the setting mode
will be exited after a few seconds.
3) Use the button
or
to set the frequency
(in steps of 25 kHz). To run through the fre-
quencies, keep the corresponding button
pressed.
4) The setting mode will be exited automatically
after a few seconds or when the button SET
is pressed.
7.3 Mode SCAN
In the mode SCAN, the receiver section will
automatically find the next free channel. When
multiple systems are operated at the same time:
Before performing the channel scan, switch on
the transmitters that have already been set to a
transmission
already being used or incompatible with the
channels already set will be skipped during the
channel scan. In this mode, depending on local
conditions, up to 12 channels can be operated at
the same time without mutual interference.
1) Use the button
SCAN (
cate the most recent radio frequency (G) and
corresponding channel number (E) adjusted
in the mode MANUAL or SCAN.
2) To activate the setting mode, keep the button
SET pressed for approx. 1 second until the
channel indication (E) and the frequency indi-
cation (G) start flashing.
Note: When no button is pressed, the setting mode
will be exited after a few seconds.
3) To start the channel scan, press the button
(scan in ascending order) or
descending order). The scan will stop when
the next interference-free channel is reached.
As long as the setting mode is still activated,
and
the scan will always restart when the button is
pressed again.
4) The setting mode will be exited automatically
after a few seconds or when the button SET
is pressed.
7.4 Mode PRESET
In the mode PRESET, a channel can be selected
from one of 4 preset groups ("P1" ... "P4")
[

8 intermodulation-free channels, i. e. channels
which may be used at the same time without

mutual interference. Thus, this mode is suitable
for operating multiple systems at the same time.
In case of interference occurring at the place of
operation, select a different group or use the
mode SCAN to set the channels for the systems.
1) Use the button

and corresponding channel number (E) ad -
justed in this mode. The indication GP (B) will
display the group to which the frequency has
been assigned ("P1" ... "P4"); the indication
CH (C) will display the channel number of the
frequency within this group ("1" ... "8").
2) Keep the button SET pressed for approx.
1 second until the channel indication (E) and
the frequency indication (G) start flashing.
The group setting mode has been activated:
The corresponding indication "P1" ... "P4" (B)
starts flashing. Use the button
select the group.
Then press the button SET to go to the
channel setting mode. In the channel setting
mode, the corresponding channel number
"1" ... "8" (C) starts flashing. Use the button
or
to select the channel within the group
selected.
Note: When no button is pressed in the group set-
ting mode, the receiver section will go to the chan-
nel setting mode after a few seconds. When no but-
ton is pressed in the channel setting mode, the
mode will be exited after a few seconds.
3) The channel setting mode will be exited auto-
matically after a few seconds or when the
button SET is pressed.
