7.1 Operation with
wireless microphone
Remove the cover from the antenna jack
beneath the receiver, connect the receiving
antenna (7) to the jack and put it in an
upright position.
1) To switch on the receiver, turn the con-
trol PWR / VOL (14) to the right. The dis-
play (8) will indicate the transmission
channel set.
2) Do not switch on the wireless micro-
phone for the time being. If, with the
microphone switched off, the red LED
RF (9) lights up, interference signals or
signals from other receivers are being
received on the channel set. In this
case, use the button DOWN or UP (12)
to select a different channel.
3) To switch on the wireless microphone,
set its power switch (4) to "ON". The
power indicator BATT (3) will light up in
green when the batteries of the micro-
phone are sufficiently charged; it will
light up in red when the batteries are
almost discharged and must be re -
placed.
4) Using an infrared signal, set the micro-
phone to the transmission channel of
the receiver:
a) Screw off the housing sleeve of the
microphone.
b) Position the microphone so that its IR
sensor (1) points to the IR transmis-
sion diode (11) of the receiver (max.
distance: 50 cm). There must be no
obstacles between the IR sensor and
the IR transmission diode.
c) Press the button ASC (10). The wire-
less microphone will be set to the
same channel as the receiver. The
red LED RF (9) will indicate radio
reception.
If the LED RF does not light up, reduce
the distance for IR transmission and
repeat the process.
5) Speak into the microphone and adjust
the volume desired with the control
PWR / VOL (14).
The green LED AF (9) will indicate
the level of the audio signal received: it
will light up when the microphone has
reached a specific volume level (inde-
pendently from the control PWR / VOL).
To readjust the volume level of the
microphone, turn the control GAIN (5)
by means of a small screwdriver: the
more the control turned to the right, the
higher the level.
6) The switch H / L (6) on the microphone
can be used to select:
H = high transmission power
L = low transmission power
Low transmission power will result in low
battery consumption, but will also
reduce the transmission range.
7) Once the settings at the microphone
have been made, screw on the housing
sleeve.
8) The control MUTE LEVEL (13) can be
used to set the threshold value for the
squelch function by means of a small
screwdriver.
The squelch function will mute the receiver
when the level of the radio signal falls below
the threshold value. Thus, interference signals
will not cause noise when the transmitter is
switched off or when its radio signal is insuffi-
cient: If the levels of the interference signals
are below the threshold value, the receiver will
be muted.
The more the control turned to the right,
the higher the threshold value. A high
threshold value offers high interference
resistance, but it will also reduce the
transmission range. When the radio sig-
nal strength of the wireless microphone
falls below the threshold value adjusted,
the receiver will be muted as well.
9) After operation, turn the control PWR/
VOL (14) to the left stop ("OFF") to
switch off the receiver and, to switch off
the microphone, set its power switch (4)
to "OFF".
If no reception is indicated or if the recep-
tion is poor, check the following:
– Batteries of the microphone discharged?
– Reception disturbed by metal objects or
other high-frequency sources?
– Reception to be improved by turning the
antenna (7)?
– Distance between the microphone and
the receiver too long?
– Transmission power of the microphone
too low and/or threshold value for the
squelch function too high?
