connected to the input jacks by means of 6.3 mm
mono plugs.
3) At the feed-through outputs LOOP OUT CH. 1 (12)
and CH. 2 (13) the signals of the inputs LEFT /
CH. 1 IN (14) and RIGHT / CH. 2 IN (15) are availa-
ble for routing them to additional units, e. g. further
transmitters or recorders. It is possible, e. g. to feed
the CH. 1 channels of several transmitters with dif-
ferent solo signals for the musicians while the mix
of the entire band is fed to the channel CH. 2 of the
first transmitter and routed from the feed-through
output LOOP OUT CH. 2 to the input CH. 2 IN of the
second transmitter, from its LOOP OUT CH. 2 to the
input CH. 2 IN of the third, etc.
The configuration of the LOOP OUT jacks corre-
sponds to fig. 8 on page 37.
The jacks LOOP OUT are directly connected to
the corresponding input jacks, i. e. with an unbal -
anced signal at an input, this signal will also be
unbalanced at the LOOP OUT jack.
4) To monitor the audio signal, connect stereo head-
phones (impedance 2
×
≥ 16 Ω) to the 6.3 mm jack
(9) or the 3.5 mm jack (8) directly to the transmitter.
The two jacks are connected in parallel. When the
two jacks are used simultaneously, make sure that
the total impedance of the two head phones does
not fall below 16 Ω for each channel (2
×
≥ 32 Ω per
headphones in case of identical headphones).
The configuration of the headphone jacks can
be found in figures 9 and 10 on page 37.
5) Connect the antenna supplied to the BNC jack
ANTENNA OUT (16) and set it up in a vertical posi-
tion.
4.3 Power supply of the receiver
The receiver is supplied with power via two batteries or
rechargeable batteries of size AA. To insert the batter -
ies, press together the two latching devices (27) and
pull the battery support downwards out of the receiver
(see fig. 6 on page 37). Slide the cover of the battery
compartment upwards and open it. When inserting the
batteries, make sure to observe the polarity printed on
the battery support. Close the battery compartment in
reverse order and slide the battery support back into
the receiver until it locks into place.
The charging status of the batteries will be indicated
as a symbol (c) on the display (23) during operation:
¡ ¡ ¡
fully charged exhausted
If the receiver is not used for a longer period (e. g.
more than a week), the batteries should be removed to
prevent damage to the unit in case of battery leakage.
4.4 Connecting the Earphones
Connect the earphones (28 and 29) supplied to the
output jack (24) of the receiver via the connection plug
(20).
The configuration of the earphone jack corre-
sponds to fig. 10 on page 37.
4.5 Selecting the transmission frequency and
the received frequency
The wireless transmission is made in the frequency
range of 518 – 542 MHz. It is possible to adjust 961 dif-
ferent frequencies in steps of 25 kHz. The transmitter
and the receiver must be set to the same frequency,
otherwise signal transmission will not be possible. To
facilitate the set-up of the system, the units have four
preset frequency groups (GROUP A – D) with 16 chan-
nels each (CH. 1 – 16).
Note: When several wireless systems are used at the
same time, the transmission frequencies of the indi -
vidual systems should be carefully matched to prevent
interference, e. g. the preset frequencies within a
group (GROUP A – D) may be selected.
4.5.1 Adjusting the frequency on the receiver
As some frequencies may already be reserved by
other users of wireless systems at the place of appli-
cation, the desired frequency should be adjusted on
the receiver before the transmitter is switched on. If a
signal is received on this frequency [one or more seg-
ments of the reception indication (a) are shown on the
display of the receiver], a different frequency should
be selected to prevent mutual interference. To adjust
the frequency, proceed as follows:
1) Switch on the receiver by turning the volume con-
trol (18) from the left stop. The display (23) will
show the current adjustments.
2) Press the button SET (26). The menu will be dis-
played with the first menu item “Frequency” select -
ed.
Either adjust a frequency as desired in steps of
25 kHz or select a preset frequency .
Frequency adjusted as desired:
a) Press the button SET. The submenu “Fre-
quency” will be indicated and a flashing triangle
will point to the current received frequency.
b) Select the new frequency with the (21)
or - (22). If the desired frequency corresponds to
one of the preset frequencies, the group and the
channel number will be indicated on the display
(e, i).
c) Press the button SET (26). At the safety request
“Setup is Changed. Do you Want to Save?
[+] Yes / [-] No”, confirm the change with the but-
ton + or cancel it with the button -. “Saving...” or
“Cancel” will shortly appear, then the menu will
be displayed again.
Never put used batteries or defective recharge-
able batteries in the household waste; always
take them to a special waste disposal, e. g. col-
lection container at your retailer.
