General information Signal word Meaning DANGER! This combination of symbol and signal word indicates an immediate dangerous situation that will result in death or serious injury if it is not avoided. WARNING! This combination of symbol and signal word indicates a pos‐ sible dangerous situation that can result in death or serious injury if it is not avoided.
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.

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.

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.

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.

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.

Installation and starting up Available operating modes Depending on the individual application, the amplifier can be used in different operation modes: Stereo mode Both power amplifier channels operate independently of each other, each input (A and B) is amplified by one channel, speakers are connected to both power amplifier channels, the volume for both outputs can be controlled separately.

For the example of two speakers with the same impedance, this means: In series connection, impedance is doubled. In parallel connection, it's halved. Detailed information on this topic can be found in our online guide “Speakers” (www.thomann.de). E4-130, E4-250 Power Amplifier...

Cleaning 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 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.
