signal of the receiver unit CH 2, for con-
nection to a microphone input or highly
sensitive line input

AF OUTPUT MIXED / BAL . (14)

balanced 6 .3 mm output jack for the

mixed signal of the two receiver units,
for connection to a microphone input or
a highly sensitive line input;

for connection to an unbalanced input,
use the cable provided

3) Connect the power supply unit provided to

the power supply jack (16) and to a mains
socket (230 V/ 50 Hz) .

6 Operation

Do not switch on the transmitters of the sys-
tem yet .

To switch on the receiver, press the button

POWER (4) . When the unit is switched on, the
rings around the REMOSET buttons (6) light
up . After briefly indicating the identification
number (

☞

chapter 6 .1 .3), the display (10) of

each receiver unit shows:
– the group

. . . (g) and the channel (h)

from the group (overview of groups and
channels

☞

table page 9)

– the indication MUTE (f)

The muting function will be activated when
no radio signal is received from the transmit-
ter on the transmission frequency adjusted,
when the signal received is poor or when the
transmitter is muted (possible for transmitter
TXS-865HT only) .

Make the following settings for each receiver
unit separately:
1) Before switching on the transmitter, set the

receiver unit to a free and interference-free
transmission frequency:

☞

chapter 6 .1 .1 .

When the transmission frequency has been
set and the reception indication RF (a) shows
a radio signal (one or several segments of
the indication are displayed), select a differ-
ent frequency .

2) Switch on the transmitter, check its settings

(

☞

instruction manual of the transmitter),

then set it to the same transmission fre-
quency via the REMOSET function according
to chapter 6 .2 .

When the transmitter and the receiver

have been set to the same frequency, the
muting function is deactivated; the indica-
tion MUTE (f) disappears . One of the indica-
tions

of the antennas (1) receives the radio sig-
nal of higher strength . The indication RF (a)
shows the reception quality: the more seg-
ments displayed, the better the reception .
If the reception is poor, please check
– if the batteries of the transmitter are dis-

charged .

The display shows a battery symbol (d)
indicating the status of the batteries in
the transmitter in four 4 levels . If the bat-
teries are discharged (indication

), the

display backlight will change from green
to orange .

– if the transmission power of the transmit-

ter is too low .

To increase the transmission range when
the transmitter and the receiver are
placed at a greater distance, it is possible

to increase the transmission power from
10 mW to 50 mW (possible for transmitter
TXS-865HT only:

☞

instruction manual of

the transmitter) .

– if the reception is disturbed by objects in

the transmission path .

Make sure to keep the transmitter and the
receiver at a minimum distance of 50 cm
from metal objects and any other sources
of interference, e . g . electric motors or
fluorescent lamps .

– if the reception is improved when you

move the antennas .

– if the squelch threshold adjusted with the

corresponding SQUELCH control is too
high:

☞

step 5 .

3) Speak / sing into the microphone of the

transmitter or, in case of an instrument mi-
crophone, feed an audio signal to the mi-
crophone . The indication AF (b) shows the
volume level of the audio signal received .
The more segments of the indication AF
displayed, the higher the level .

Set the transmitter to the optimum vol-

ume via the indication AF:

☞

instruction

manual of the transmitter .

4) If the volume level is too high for the subse-

quent unit, it will be possible to attenuate
it by 10 dB or 20 dB . For each audio output,
an attenuation switch is provided: the corre-
sponding switches ATTENUATION CH 1 and
CH 2 (13) for the two XLR outputs (11); the
switch ATTENUATION (15) for the 6 .3 mm
output jack (14) .

5) Use the control SQUELCH (12) to adjust the

threshold for interference suppression of
the corresponding receiver unit . The further
the control turned clockwise, the higher the
threshold .

Interference suppression will mute the

receiver unit when high-frequency interfer-
ence signals with levels below the threshold
adjusted are received during music intervals .
With a higher threshold, however, the trans-
mission range will decrease as the receiver
unit will also be muted when the strength
of the radio signal of the transmitter falls
below the threshold adjusted . Therefore,
adjust a higher threshold when the recep-
tion is good; select a lower value when the
transmitter and the receiver are placed at
the greater distance .

6) Each receiver unit is provided with a lock

function to prevent accidental change of
settings or switching off:

☞

chapter 6 .1 .4 .

To switch off the unit, keep the button POWER
(4) pressed for a few seconds . If the receiver
is not in use for a longer period of time, dis-
connect the power supply unit from the mains
socket; even when the receiver is switched off,
it will have a low power consumption .

6.1 Adjusting the receiver unit

When the receiver unit is not locked, press the
button SET (8) to activate the setting modes
one after another:

To make settings in a setting mode, see the
corresponding chapter 6 .1 .1 to 6 .1 .4 .

To exit a setting mode without changing a set-
ting, press the button SET repeatedly until the
display briefly shows

(= cancel) . The re-

ceiver unit will then return to the normal mode .

6.1.1 Transmission frequency (group /channel)

To set the transmission frequency, select the
channel group and the channel . Six channel
groups with preset channels in different num-
bers are available:

☞

table page 9 .

Note:

To prevent interference, carefully match the

transmission frequencies of all transmission paths to
one another . In case of parallel operation of several
channels, it is recommended to use channels from
the same group .

1) Keep the button SET (8) pressed until the

letter “G” starts flashing on the display; the
group setting mode is activated .

2) Select the group ( . . . ) with the button

(7) or the button (9) .

3) Press the button SET to confirm . The letters

“CH” start flashing on the display; the chan-
nel setting mode is activated .

Select the channel with the button

or . When the scan function has been
activated (

☞

chapter 6 .1 .2), each time a

channel is selected, the unit will check if
the correspond ing transmission frequency is
presently being used for transmission (brief
insertion

= “scan channel”) . If it is,

this channel already used will be skipped .

Note:

It will not be possible to set both receiver

units to the same channel of a group . The channel
used for one receiver unit will be locked for the
other one .

4) Press the button SET to confirm . The display

briefly shows

(= store) . The receiver

unit will return to the normal mode .

6.1.2 Scan function

The scan function makes it easier to select a
free transmission frequency: When the func-
tion has been activated, the frequencies already
being used for transmission will be skipped
when you set the transmission frequency
(

1) Keep the button SET (8) pressed until the

letter “G” starts flashing on the display; the
group setting mode is activated .

2) Press the button SET repeatedly until the

display shows the current setting for the
scan function:

scan function activated

scan function deactivated
