NOTICE!
Possible staining
The plasticiser contained in the rubber feet of this product may possibly react with the coating of your parquet, linoleum, laminate
or PVC oor and after some time cause permanent dark stains. In case of doubt, do not put the rubber feet directly on the oor, but
use felt-pad oor protectors or a carpet.
NOTICE!
Possible damage due to installation of a wrong fuse
The use of dierent types of fuses can cause serious damage to the unit. Fire hazard! Only fuses of the same type may be used.
NOTICE!
Possible damage to lithium-ion batteries through incorrect storage
By deep discharge, lithium-ion batteries can be permanently damaged or lose some of their capacity. Before long breaks, charge the
batteries to around 50 % of their capacity and then switch o the device. Store the device at room temperature or cooler in an envi‐
ronment as dry as possible. If the batteries are stored for a longer period, recharge them to 50 % every three months. Fully charge
the batteries only shortly before use at room temperature.

Installation and starting up
4.1 Dealing with lithium batteries
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 aected surface thoroughly with cold water.
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.
16
active 2-way speaker
Installation and starting up
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.

Introduction
Balanced and unbalanced trans‐
mission
26
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 ts 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 hi 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°.

Plug and connection assignment
Since the interference aects 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.

Cleaning
8 Cleaning
Device components
30
Clean the device components that are accessible from the outside regularly. The cleaning fre‐
quency depends on the operating environment: damp, smoky or particularly dirty environ‐
ments can cause greater accumulation of dirt on the device components.
n Clean with a dry soft cloth.
n Stubborn dirt can be removed with a slightly dampened cloth.
n Never use solvents or alcohol for cleaning.

9 Protecting the environment
Disposal of the packaging mate‐
rial
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.
Disposal of batteries
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.
Dispose lithium batteries only in discharged condition. Remove lithium batteries from the
device before disposal. Protect used lithium batteries against potential short circuits, e.g. by
covering the poles with adhesive tape. Dispose the built-in lithium batteries together with the
device. Please check for an appropriate reception facility.
