WARNING
Improper electrical installation
or excessive mains voltage may
result in an electrical shock.
–The device is suitable for a
mains voltage of 230 V ~ /
50–60 Hz. When connecting
the device, make sure that the
correct voltage is present. You
can find more information in
this respect on the rating plate.
–Check the device regularly for
damage.
Immediately disconnect the
mains plug and do not oper-
ate the device if its housing or
mains cable is defective or ex-
hibits other visible damages.
–If the device emits smoke,
smells burnt or produces
unusual sounds, immediately
disconnect it from the mains
or the battery and do not
operate it further.
–Never open the device hous-
ing.
Repairs may only be carried
out by an authorised specialist
workshop. In the process, only
parts that correspond to the
original device data may be
used.
–Only use the accessory prod-
ucts specified by the manu-
facturer.
–Do not use the ROCKSTER in
environments where there is
a risk of explosion.
–Do not operate the device in
wet rooms and protect it from
dripping and splash water.
Make sure that no vases or
other vessels filled with liquid
are located on or near the de-
vice in order to prevent liquid
from penetrating the housing.
If water or other debris ends
up penetrating the housing,
immediately pull the mains
plug and remove the recharge-
able battery. Then contact our
service address.
–Never touch the mains plug
with wet hands.
–Never modify the device. Un-
authorized interventions may
affect the safety and function-
ality.
–Power overload due to a
lightning strike may damage
or destroy the unit. If the unit
is unattended for a prolonged
period (e.g. when on vacation)
or in the event of an incoming
storm, pull the mains plug.

6• Rockster
WARNING
An unstable base may cause
the unit to tip and injure or even
kill persons, children are par-
ticularly at risk. You can prevent
a large number of accidents
by taking the following precau-
tions:
–If the ROCKSTER is not secure-
ly mounted, do not use it in
vehicles, in unstable locations,
on wobbly tripods or furniture,
with insufficient brackets etc.
The ROCKSTER may tip or fall
over and cause injury to per-
sons or be damaged itself.
–Place the ROCKSTER in
such a way that it cannot be
knocked over inadvertent-
ly and make sure that the
cables do not pose a trip
hazard.
–Use the fixing brake to prevent
the ROCKSTER from rolling
away.
–When storing the ROCKSTER,
also ensure that it stands
safely and that it cannot be
knocked down or over.
WARNING
Children can become trapped
in the plastic wrapping when
playing and suffocate.
–Do not allow children to play
with the ROCKSTER and the
plastic wrapping. Danger of
suffocation.
–Ensure that children do not
remove small parts from the
ROCKSTER or take them off
of the device (e.g. control
knobs or plug adapters). They
could swallow the parts and
choke.
–Never allow children to oper-
ate electrical devices unsu-
pervised.
CAUTION
Extended listening at
high volumes may lead
to hearing loss .
–To avoid damage to health,
avoid extended listening at
high volumes.
–At high volumes, always
maintain a certain distance
to the ROCKSTER and never
hold your ears directly up to a
speaker.

7• Rockster
–If an audio system is set to
full volume, it may produce
very high sound pressure.
This may have psychological
consequences and also cause
physical injury. Children and
pets are particularly at risk.
Set the volume control of the
ROCKSTER to a low setting
before turning on the power.
WARNING
Handling rechargeable batter-
ies improperly may lead to fire
or explosion!
–Keep the rechargeable battery
away from paper clips, coins,
keys, screws or other metal-
lic objects that could bridge
the contacts. Short circuiting
caused by bridged recharge-
able battery contacts may
result in burns or fire.
–Never carry the rechargeable
battery by the poles.
–Avoid bumps and abrupt
stresses.
–Avoid electrostatic charge or
discharge. Never use synthet-
ic cloths or sponges to clean
the rechargeable battery;
instead only use cloths mois-
tened with water without any
additives.
–Only charge the rechargeable
battery when it is installed in
the ROCKSTER. A normal car
battery charger is not suita-
ble.
WARNING
Risk of injury!
If used incorrectly, corrosive
battery acid may leak out of the
rechargeable battery.
–Avoid any contact with it.
–In the event of accidental
contact, immediately rinse
with plenty of water and seek
medical attention.
NOTICE
If the ROCKSTER is subjected to
warm temperatures after being
cold (e.g. after transport), con-
densation may occur inside of it.
–In this case, wait at least 2
hours before you connect and
activate the ROCKSTER.
NOTICE
Improper handling of the ROCK-
STER may lead to damage or
fire.
–Do not place open fire sourc-
es such as burning candles or
similar on the ROCKSTER.

8• Rockster
–Do not expose the ROCKSTER
to direct sunlight.
–Do not place the ROCKSTER
near heat sources (e.g. heat-
ers, ovens).
–Ensure sufficient ventilation.
–Do not cover the vents with
curtains, blankets, posters or
similar. The build-up of heat
inside the ROCKSTER can
shorten its lifetime.
–Before you pull the rain cover
(available accessory) over
the ROCKSTER, switch the
ROCKSTER off completely.
The ROCKSTER could be
damaged if operated under
the rain cover.
NOTICE
Gross misuse and incorrect
care are the main reasons for
damage to high-performance
rechargeable batteries.
–Avoid deep discharge of
under 20% for optimal re-
chargeable battery power.
–Recharge your rechargeable
battery frequently.
–Store your rechargeable bat-
tery in a cool, but frost-free
area, ideally at 15 °C. Higher
temperatures result in a high-
er rate of self-discharge and
shorten the intervals between
charges.
–Do not expose the recharge-
able battery to direct sunlight
or other sources of heat.
–A deep discharge damages
the rechargeable battery
cells. The most frequent
cause of deep discharge is
prolonged storage or failure
to use a partially discharged
rechargeable battery. Only
store the rechargeable bat-
tery once it is fully charged.

Explanation of symbols
Protection class II
Dual insulation
Risk of electrical shock – do
not open the housing.
Disconnect the mains cable
before changing a fuse.
Old devices must not be
disposed of with house-
hold waste!
If the ROCKSTER is no longer
operational, every consumer is re-
quired by law to dispose of old devices
separately from household waste,
e.g. at a collection point run by the
communal authority/boroughs. This
ensures that old devices are recycled
in a professional manner and also
rules out negative consequences for
the environment.
For this reason, electrical equipment is
marked with the following symbol.
Used rechargeable bat-
teries must not be dis-
posed of with household
waste!
Every consumer is required by law to
bring all batteries and rechargeable
batteries, regardless whether they con-
tain harmful substances*) or not, to a
collection point run by the communal
authority or borough or to a retailer,
so that they can be disposed of in an
environmentally friendly manner.
Please only turn in batteries and re-
chargeable batteries which are empty!
*) labelled with: Cd = cadmium,
Hg = mercury, Pb = lead

Introduction
The ROCKSTER is an active speak-
er system. By connecting multiple
ROCKSTERs in master-slave operation,
you can even completely supply large
rooms with sound.
The power supply can be provided via
the mains, the built-in rechargeable
battery or an external 12-volt source
(car battery). The ROCKSTER is also
ideal for outdoor events.
The following inputs are available for
your source devices:
Mixer channel 1
• Bluetooth®
• Stereo line (RCA)
• Mono instrument (6.3 mm jack)
Mixer channel 2
• Bluetooth®
• Stereo line (3.5 mm jack)
• Mono microphone input (XLR)
Every mixer channel has its own
3-band sound control (100 Hz, 1 kHz,
10 kHz) and a volume control that can
be used to adjust the sound to perfect-
ly suit the local acoustics.
You can assign a reverberation effect
to the “Instrument” and “Microphone”
inputs.
With the monitor headphones, you can
position the next track and use the
cross fader to fade between the mixer
channels.
