CAUTION!
Possible hearing damage

The device can produce volume levels that may cause temporary or permanent
hearing impairment. Over an extended period of time, even levels that seem to
be uncritical can cause hearing damage.

Decrease the volume level immediately if you experience ringing in your ears or
hearing impairment. If this is not possible, keep a greater distance or use suffi‐
cient ear protectors.

WARNING!
Incorrect handling of lithium batteries can result in injury

In the event of a short circuit, overheating or mechanical damage, lithium bat‐
teries can cause severe injuries.

Follow the advice on the correct handling of lithium batteries in the present sec‐
tion.

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.

NOTICE!
Possible damage due to incorrect storage

Deep discharge can cause batteries to become permanently damaged or lose
some of their capacity.

Before prolonged rest periods, charge the batteries to around 50 % of their
capacity and then switch the equipment off. Store the equipment at a tempera‐
ture between 10 °C and 32 °C in as dry an environment as possible. During
extended storage periods, charge the batteries to 50 % approximately every three
months.

4 Installation and starting up

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.

NOTICE!
Possible property damage by magnetic fields

Loudspeakers produce a static magnetic field. Therefore, maintain an appropriate
distance to devices that can be adversely affected or damaged by an external
magnetic field.

NOTICE!
Use of stands

When mounting the device onto a stand, ensure that the stand is in a safe and
stable position and that the weight of the device does not exceed the maximum
permissible load capacity of the stand.

The device is prepared for the connection of a wireless-receiver. The 9,5'' receiver can be stored
in the front part of the housing flap and be secured with the hook-pile tape. Connect the 12-V­power supply output (4) of the box with the corresponding input of the wireless-receiver and
the signal input (5) of the box with signal output of the wireless-receiver (see also

Ä

Chapter 5

‘Connections and operating elements’ on page 15).

You can also operate the device independent of the mains power supply via the two built-in
lithium-mangan-batteries. When the external mains power supply is connected, the battery is
charged during operation.

4.1 Dealing with lithium batteries

WARNING!
Incorrect handling of lithium batteries can result in injury

In the event of a short circuit, overheating or mechanical damage, lithium bat‐
teries can cause severe injuries.

Follow the advice on the correct handling of lithium batteries in the present sec‐
tion.

When handled correctly and appropriately lithium batteries pose no risk.
Store lithium batteries in a cool, dry place, ideally in the original packaging.
Store lithium batteries away from heat sources (e.g. radiators or sunlight). Lithium batteries are

hermetically sealed. Never attempt to open a lithium battery.
If the battery housing is damaged small amounts of the electrolyte may leak out. If this should

happen, seal the lithium battery in airtight packaging and wipe up the traces of electrolyte
using absorbent paper towels. You must wear protective rubber gloves when doing so. Clean
your hands and the affected surface thoroughly with cold water.

Never attempt to recharge non-rechargeable lithium batteries. When charging lithium bat‐
teries you must use a suitable charging device intended for the purpose.

Before disposing of the device remove the lithium batteries. Protect used lithium batteries
against potential short circuits, e.g. by covering the poles with adhesive tape.

Only use powder extinguishers or other suitable extinguishing agents to extinguish a burning
lithium battery.

7 Plug and connection assignments

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.

8 Protecting the environment

For the 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 of these materials with your normal household waste, but make sure that

they are collected for recycling. Please follow the notes and markings on the packaging.

Batteries do contain some hazardous chemicals so they should not be thrown away with the
normal household waste. They should be returned to the manufacturer for disposal or recycled
elsewhere in accordance with your local regulations.

Remove lithium batteries from the device before disposal. Protect used lithium batteries
against short circuit, for example by taping the poles.
