  • Page 7: Safety Instructions

    Safety instructions Safety instructions Intended use This device amplifies electric audio frequency signals to operate passive speakers. Use the device only as described in this user manual. Any other use or use under other operating con‐ ditions 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.
  • Page 8 Safety instructions DANGER! Danger to life due to electric current! A short circuit could lead to a fire hazard and risk of death. Always use proper ready-made insulated triple-core mains cable with a safety plug. Do not modify the mains cable or the plug. In case of isolation damage, disconnect immediately the power supply and arrange repair.
  • Page 9 Safety instructions NOTICE! Damage to the device due to high voltages! The device can be damaged if it is operated with the incorrect voltage or if high voltage peaks occur. In the worst case, excess vol‐ tages can also cause a risk of injury and fires. Make sure that the voltage specification on the device matches the local power grid before plugging in the device.

  • Page 11: Installation And Starting Up

    Installation and starting up Installation and starting up Unpack and check carefully there is no transportation damage before using the unit. Keep the equipment packaging. To fully protect the product against vibration, dust and moisture during transportation or storage use the original packaging or your own packaging material suitable for transport or storage, respectively.
  • Page 12 Installation and starting up NOTICE! Interference with nearby electrical devices due to magnetic fields! The device generates strong magnetic fields that can interfere with the function of poorly shielded devices. The magnetic fields are strongest directly above and below the Power Amplifier. You should therefore never place sensitive devices such as pre-amplifiers, radio transmission systems, or tape decks directly above or below the Power Amplifier.
  • Page 13 Installation and starting up Possible operation modes Depending on the individual application, the amplifier can be used in different operation modes: Stereo mode The two amplifier channels operate independently of one another, either channel (A and B) is amplified and connected to loudspeakers, the volume can be controlled separately for the two outputs.
  • Page 14 For detailed information related to this topic please refer to our Online Guide ‘PA Speakers’ (www.thomann.de). Rack mounting The device has been designed for rack mounting in a standard 19-inch rack; it occupies two rack units.
