Troubleshooting

With this power amplifier, you purchased a product built to the state of the art and operationally safe. Nevertheless,
problems or errors may occur. The following contains descriptions for the removal of possible interferences.

Always observe the safety information!

No function, the device cannot be switched on:

• Is the mains plug connected to the mains socket?

• Is the amplifier’s fuse defective?

• Check the mains socket. Is it properly supplied with current?

No sound is audible:

• Are the LEVEL (2) volume controls of the amplifier set to minimum (left stop)?

• Are audio source and speakers connected correctly?

• Is the audio source switched on and its volume control not set to minimum?

One channel does not work:

• Are the inputs and speakers connected correctly? Has a plug come loose?

• Is the audio source’s balance control in the centre position?

• Is one of the LEVEL (2) volume controls of the amplifier set to minimum (left stop)?

The sound is distorted:
• The level at the mixer is set incorrectly/the amplifier input is overmodulated.

• The volume at the amplifier is set too high.

A humming distortion can be heard:

• Are the signal cables from the audio source okay?

• There is a ground hum between the connected devices. Connect the signal ground with special earth-insulated

cables.

Playback has no bass share:

• Is one of the speakers connected with the polarity reversed?

Repairs other than those described above must only be carried out by an authorised specialist.
