Intended useThis device is designed for sound reinforcement. Use the device only as described in this user manual. Any other use or use under other operating 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 childrenEnsure that plastic bags, packaging, etc. are disposed of properly and are not within reach of babies and young children. Choking hazard! Ensure that children do not detach any small parts (e.g. knobs or the like) from the unit. They could swallow the pieces and choke! Never let children unattended use electrical devices.DANGER!Electric shock caused by high voltages insideWithin the device, there are areas where high voltages may be present. Never remove any covers. There are no user-serviceable parts inside. Do not use the device if covers, protectors or optical components are missing or damaged.
DANGER!Electric shock caused by short-circuitAlways use proper ready-made insulated mains cabling (power cord) with a protective 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 registered electrician.CAUTION!Possible hearing damageThe 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 sufficient ear protectors.WARNING!Incorrect handling of lithium batteries can result in injuryIn the event of a short circuit, overheating or mechanical damage, lithium batteries can cause severe injuries. Follow the advice on the correct handling of lithium batteries in the present section.NOTICE!Risk of fireDo not block areas of ventilation. Do not install the device near any direct heat source. Keep the device away from naked flames.
NOTICE!Risk of fire due to the incorrect polarityIncorrectly inserted batteries may destroy the device or the batteries. Ensure that proper polarity is observed when inserting batteries.NOTICE!Operating conditionsThis 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 strong vibrations. Only operate the device within the ambient conditions specified in the chapter ‘Technical specifications’ of this user manual. Avoid heavy temperature fluctuations and do not switch the device on immediately after it was exposed to temperature fluctuations (for example after transport at low outside temperatures). Dust and dirt inside can damage the unit. When operated in harmful ambient conditions (dust, smoke, nicotine, fog, etc.), the unit should be maintained by qualified service personnel at regular intervals to prevent overheating and other malfunction.NOTICE!Possible damage by leaking batteriesLeaking batteries can cause permanent damage to the device. Take batteries out of the device if it is not going to be used for a longer period.
NOTICE!Possible damage to lithium-ion batteries through incorrect storageBy deep discharge, lithium-ion batteries can be permanently damaged or lose some of their capacity.

Dealing with lithium batteries
WARNING!Incorrect handling of lithium batteries can result in injuryIn the event of a short circuit, overheating or mechanical damage, lithium batteries can cause severe injuries.Follow the advice on the correct handling of lithium batteries in the present section.
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 batteries 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.

Plug and connection assignment
This chapter will help you select the right cables and plugs to connect your valuable equipment in such a way that a perfect sound experience is ensured.Please note these devices, 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!
Balanced and unbalanced trans-mission
Unbalanced transmission is mainly used in semi-professional environments 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 hielding while the signal is transmitted 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, balanced transmission is preferred, because this enables an undisturbed transmission of signals over long distances. In addition to the conductors ‘Ground’ and ‘Signal’, in a balanced transmission, a second core is added. This also transfers the signal but is phase-shifted by 180°.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.

Clean the device components that are accessible from the outside regularly. The cleaning frequency depends on the operating environment: damp, smoky or particularly dirty environments can cause a greater accumulation of dirt on the device components.
- Clean with a dry soft cloth.
- Stubborn dirt can be removed with a slightly dampened cloth.
- Never use solvents or alcohol for cleaning.
