2) Switch on the amplifier with the POWER switch
(13). When the unit is switched on, the switch
will be illuminated.
3) Switch on the audio sources used and mix their
signals with the corresponding volume controls
or fade them in and out as required (operation
with a microphone IRS-2..HT
chapter 7.1).
Adjust the desired sound for reproduction via
the speakers with the bass control BASS and
the treble control TRE (16). To turn the recessed
controls, use a narrow object, e. g. screwdriver.
4) The signal adjusted with the volume controls is
also present at the jack AUX OUT (29). Adjust
the total volume for the AUX OUT signal with the
control AUX (28) and its sound with the three
equalizer controls HF, MF and LF (27).
The tone controls on the front side will not
affect the AUX OUT signal.
5) After operation, switch off the amplifier with the
POWER switch .
If the unit is not in use for a longer period of
time, also disconnect the plug of the power sup-
ply unit from the mains socket; even with the
amplifier switched off, the power supply unit will
have a low power consumption.
7.1 IR transmission
The IR transmitter microphone IRS-200HT is fac-
tory-set to channel A; the IR transmitter micro-
phone IRS-202HT to channel B (change of factory
settings
chapter 6.1). An individual on / off switch
and volume control for each channel is provided on
the receiver unit of the amplifier: They are colour-
coordinated with the corresponding microphone
head: black (19) for channel A, grey (23) for chan-
nel B:
1) To switch on the IR transmitter microphone,
keep the button
(2) pressed until it lights up.
The lighting colour of the button will indicate the
battery status: green = sufficient, red = low.
2) On the receiver unit, turn up the corresponding
control from the position “OFF” to activate the
channel. The LED next to the control [CH.A (20)
for channel A, CH.B (22) for channel B] shows
red when the channel has been activated but
does not receive an IR signal on its frequency
and shows green when an IR signal is received.
When a channel has been activated, the
power LED (15) of the IR sensor and the power
LED (12) of each IR sensor IRS-200IR con-
nected will light up.
3) Speak into the microphone or reproduce the
sound of a unit connected to the input (3). When
holding the IRS-2..HT in your hand, always
make sure that the IR transmitters (1) are not
covered.
4) Adjust the volume with the corresponding con-
trol on the receiver unit. When the audio output
signal of the receiver unit has reached a specific
level, the LED AF (21) starts to light up.
5) To mute the sound, slide the switch (4) on the
microphone downwards (position “MUTE”). To
deactivate the muting, slide the switch upwards
again (position “TALK”).
6) To deactivate the reception channel, turn back
its volume control to “OFF”; the corresponding
status LED next to the control goes out.
To switch off the microphone, keep the but-
ton
pressed until it is no longer illuminated.
