3 Installation and starting up

3.1 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.

NOTICE!
External power supply

The device is powered by an external power supply. Before connecting the
external power supply, ensure that the input voltage (AC outlet) matches the
voltage rating of the device and that the AC outlet is protected by a residual cur‐
rent circuit breaker. Failure to do so could result in damage to the device and pos‐
sibly the user.

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

First, connect the power adapter to the receiver and then plug the power adapter into the
power outlet.

Connect the audio output of the receiver to your mixer or your amplifier.
Set the volume control first as follows:

n If you are using a microphone input of your mixer, turn the knob to about 1 o'clock.
n If you are using a line input of your mixer, turn the knob clockwise all the way to the stop.

To get the best sound quality, a fine adjustment of the controller may be required.

6 Plug and connection assignment

This chapter will help you select the right cables and plugs to connect your valuable equip‐
ment in such a way that a perfect sound experience is ensured.

Please note these advices, because especially in ‘Sound & Light’ caution is indicated: Even if a
plug fits into the socket, an incorrect connection may result in a destroyed power amp, a short
circuit or ‘just’ in poor transmission quality!

Unbalanced transmission is mainly used in semi-professional environment and in hifi use.
Instrument cables with two conductors (one core plus shielding) are typical representatives of
the unbalanced transmission. One conductor is ground and shielding while the signal is trans‐
mitted through the core.

Unbalanced transmission is susceptible to electromagnetic interference, especially at low
levels, such as microphone signals and when using long cables.

In a professional environment, therefore, the balanced transmission is preferred, because this
enables an undisturbed transmission of signals over long distances. In addition to the conduc‐
tors ‘Ground’ and ‘Signal’, in a balanced transmission a second core is added. This also transfers
the signal, but phase-shifted by 180°.

Introduction

Balanced and unbalanced trans‐
mission

Since the interference affects both cores equally, by subtracting the phase-shifted signals, the
interfering signal is completely neutralized. The result is a pure signal without any noise inter‐
ference.

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

UHF wireless system

26

Symptom Remedy

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

2. Make sure that transmitter and receiver are operating in the same frequency

range. The frequency can be found on the devices.

3. Test the connection between the receiver and the connected audio device

(amplifier, mixer). Is the connected audio device turned on and does the signal

level at the output of the receiver match the input requirements of the audio

device?

4. See if the audio transmission works when you move the transmitter closer to

the receiver.

5. Make sure that no metal objects near the transmitter or receiver obstruct the

transmission.
Transmission is interrupted. 1. Change the orientation of the antenna.

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

frequencies and channels.

Symptom Remedy

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

The sound is distorted. Toggle the sensitivity selector switch on the transmitter of change the setting of

the controller [VOLUME on the receiver].

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

8 Protecting the environment

For the transport and protective packaging, environmentally friendly materials have been
chosen that can be supplied to normal recycling.

Ensure that plastic bags, packaging, etc. are properly disposed of.
Do not just dispose these materials with your normal household waste, but make sure that

they are fed to a recovery. Please follow the notes and markings on the packaging.

Batteries must not be disposed of as domestic waste or thrown into fire. Dispose of the bat‐
teries according to national or local regulations regarding hazardous waste. To protect the
environment, dispose of empty batteries at your retail store or at appropriate collection sites.
