6.2 Carrying strap IRS-200H (optional)
The carrying strap IRS-200H available as an
accessory and consisting of a strap of adjustable
length and a removable belt clip allows you to wear
the microphone around your neck or to attach it to
your clothes. To insert the microphone into the car-
rying strap, unscrew the microphone head, replace
the ring underneath it in front of the IR LEDs (1) by
the ring on the strap, then screw on the microphone
head again.

6.3 Connection of an audio source
An input jack (3) for an audio source is provided on
the lower side of the IRS-2..HT. When this jack is
connected, the internal microphone will be deacti-
vated.
The 3.5 mm jack is primarily provided for connecting
a tie clip microphone or headband microphone, e. g.
if you wear the IRS-2..HT on your body (
chap-
ter 6.2) and want to keep your hands free. Connect
the tie clip/headband microphone via a mono plug;
the audio signal and the operating voltage of the
microphone will be routed via the tip of the plug.
As an alternative, it is possible to connect a
portable audio unit with line level (e. g. MP3 player).
Due to the wiring of the jack (
chapter 8 Speci -
fications), however, the right channel will be repro-
duced at a lower volume than the left channel if you
connect the unit via a stereo plug.

Operation
1) Switch on the receiver with the POWER switch
(13).
2) To switch on the IR transmitter microphone,
keep the button
(2) pressed until it lights up.
The lighting colour will indicate the battery sta-
tus:
green = sufficient; red = low
3) The microphone IRS-200HT is factory-set to
channel A; the microphone IRS-202HT to chan-
nel B (change of factory setting
chapter 6.1).
An individual on/off switch and volume control
for each channel is provided on the receiver.
They are colour-coordinated with the corre-
sponding microphone head: black (14) for chan-
nel A, grey (18) for channel B. Turn up the cor-
responding control from the locking position
“OFF” to activate the channel. The LED next to
the control [CH.A (15) for channel A, CH.B (17)
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 (12) of each IR sensor IRS-200IR
connected will light up.
4) 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.
5) Adjust the volume with the corresponding con-
trol on the receiver. When the audio output sig-
nal of the receiver has reached a specific level,
the LED AF (16) starts to light up.
6) 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”).
7) 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.
8) After operation, switch off the receiver with the
POWER switch. If the unit is not in use for a
longer period of time, also disconnect the power
supply unit from the mains socket; even with the
receiver switched off, the power supply unit will
have a low power consumption.
