2 Safety instructions

This device is intended to be used for the wireless transmission of audio signals to earplugs.
Use the device only as described in this user manual. Any other use or use under other oper‐
ating conditions is considered to be improper and may result in personal injury or property
damage. No liability will be assumed for damages resulting from improper use.

This device may be used only by persons with sufficient physical, sensorial, and intellectual
abilities and having corresponding knowledge and experience. Other persons may use this
device only if they are supervised or instructed by a person who is responsible for their safety.

DANGER!
Danger for children

Ensure that plastic bags, packaging, etc. are disposed of properly and are not

DANGER!
Electric shock caused by high voltages inside

Within the device there are areas where high voltages may be present. Never
remove any covers.

There are no user-serviceable parts inside.

DANGER!
Electric shock caused by short-circuit

Always use proper ready-made insulated mains cabling (power cord) with a pro‐
tective contact plug. Do not modify the mains cable or the plug. Failure to do so
could result in electric shock/death or fire. If in doubt, seek advice from a regis‐
tered electrician.

CAUTION!
Possible hearing impairment

The use of earphones at high volume over a longer period of time can cause per‐
manent hearing damage.

Adjust the output volume of your audio device to a medium value and use the
earphones no longer than about one hour a day.

NOTICE!
Operating conditions

This device has been designed for indoor use only. To prevent damage, never
expose the device to any liquid or moisture. Avoid direct sunlight, heavy dirt, and

NOTICE!
Power supply

Before connecting the device, ensure that the input voltage (AC outlet) matches
the voltage rating of the device and that the AC outlet is protected by a residual
current circuit breaker. Failure to do so could result in damage to the device and
possibly injure the user.

Unplug the device before electrical storms occur and when it is unused for long
periods of time to reduce the risk of electric shock or fire.

NOTICE!
Risk of fire due to incorrect polarity

Incorrectly inserted batteries may destroy the device or the batteries.
Ensure that proper polarity is observed when inserting batteries.

4 Installation and starting up

4.1 General information

Unpack and carefully check that there is no transportation damage before using the unit. Keep
the equipment packaging. To fully protect the device against vibration, dust and moisture
during transportation or storage use the original packaging or your own packaging material
suitable for transport or storage, respectively.

Establish all connections as long as the unit is switched off. Use the shortest possible high­quality cables for all connections.

n This device utilizes frequencies that are not harmonized within the European Union (EU)

and therefore may only be used in certain EU member states. In all European countries, the
frequencies used for the transmission of audio signals are strictly regulated. Before you
start, make sure the frequencies are allowed in the respective country and check whether
the operation must be reported to the appropriate authority.

For more information, please visit: http://www.thomann.de.

n Make sure that transmitter and receiver are both tuned to the same channel.
n Never set multiple transmitters to the same channel.
n Make sure that there are no metal objects between the transmitter and receiver.
n Avoid interference from other radio or in-ear systems.

The unit has been designed for rack mounting in a standard 19-inch rack; it occupies one rack
unit.

Attach the included antenna to the back of the transmitter. To improve the transmission
quality and for adaptation to the specific spatial conditions, the antenna can be rotated and
swivelled.

Connect the audio inputs of the transmitter to suitable outlets of your mixing console or
amplifier. Set the volume control (6) to a mid position first.

To achieve best sound quality, a fine adjustment of this control may be required. If the input
level is too high, enable the level attenuation function ( Ä ‘Enabling attenuation’ on page 40).

Make sure that the main switch / volume control (17) of the receiver is in ‘OFF’ position.
Simultaneously press on both snap-in locks of the battery compartment at the side and pull it

completely out of the receiver. Open the battery compartment lid by sliding the lid in arrow
direction and then folding it up. Insert the batteries respecting the correct polarity. Close the
battery compartment, the lid must snap-in firmly.

n Make sure that both transmitter and receiver are switched off. The transmitter display is

dark; the main switch / volume control (17) is in ‘OFF’ position.

n Attach the receiver with the clip to your belt or guitar strap.
n Carefully insert the earplugs into the ear canal, observing the markings ‘L’ and ‘R’ for left

and right sides.

n Turn the transmitter on by pressing the main switch (1), turn the receiver on by turning the

main switch / volume control (17). Then test the transmission. Make sure that both trans‐
mitter and receiver are set to the same frequency group and the same channel. If neces‐
sary, adjust the volume on transmitter and receiver as well as the mixer or amp levels.

7 Troubleshooting

In the following we list a few common problems that may occur during operation. We give you
some suggestions for easy troubleshooting:

Troubleshooting

IEM 200

45

Symptom Remedy

No sound 1. Check the power supply of the transmitter and receiver.

2. Make sure that both transmitter and receiver operate in the same frequency
range and that the transmitting antenna is designed for this frequency range.
The frequency range is stated on the devices.

3. Are both transmitter and receiver set to the same frequency group and the
same channel?

4. Check the connection between the transmitter and the connected audio
device (amp, mixer). Is the connected audio device switched on and does the
output signal level of the audio device match the input sensitivity of the trans‐
mitter?

5. Try to improve the transmission by moving the receiver closer to the trans‐
mitter.

Transmission interference 1. Make sure that no metal objects near the transmitter or receiver obstruct the

transmission.

2. Modify the orientation of the antennas.

Troubleshooting

UHF wireless system

46

Symptom Remedy

2. If you use more than one wireless system at the same time, check the used
frequency groups and channels.

3. Interference can also be caused by televisions, radios or mobile phones.

The sound is distorted 1. Change the ‘VOLUME’ setting on the transmitter.

2. Turn the overload protection on.

If the procedures recommended above do not succeed, please contact our Service Center. You
