Safety instructions 2 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.
Safety instructions DANGER! Electric shock caused by high voltages inside Within 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-circuit Always use proper ready-made insulated mains cabling (power cord) with a protective contact plug. Do not modify the mains cable or the plug.
Safety instructions NOTICE! Operating conditions This 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.

Installation and starting up 4 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. Create all connections while the device is off. Use the shortest possible high-quality cables for all connections.
Installation and starting up NOTICE! Magnetic fields The device generates strong magnetic fields that can interfere with the function of poorly shielded devices. The strongest magnetic fields are directly above and below the power amplifier. Therefore, never place sensitive devices such as preamplifiers, radio transmission systems, or tape decks directly above or below the power amplifier.
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.
Installation and starting up For each output of the amplifier, the total impedance resulting from the loudspeakers con‐ nected to it must not be below the allowed minimal impedance of the amplifier output. If you connect more than one loudspeaker to an amplifier output, please note the following: n If the loudspeakers are connected in a series, the individual impedances will be added up.

Plug and connection assignment 7 Plug and connection assignment Introduction 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.
Plug and connection assignment 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.

Cleaning 8 Cleaning Fan grids The fan grids of the device must be cleaned of any contamination, such as dust, etc. on a reg‐ ular basis. Before cleaning, switch off the device and disconnect mains-operated devices from the mains. Only use pH-neutral, solvent-free and non-abrasive cleaning agents. Clean the unit with a slightly damp lint-free cloth.
Protecting the environment 9 Protecting the environment Disposal of the packaging mate‐ rial For the transport and protective 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.
