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.

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 incorrect polarityIncorrectly inserted batteries may destroy the device or the batteries.Ensure that proper polarity is observed when inserting batteries.

Plug and connection assignment

  • IntroductionThis 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 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!
  • Balanced and unbalanced transmissionUnbalanced 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 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, the 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 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 interference.
