CAUSE:
• The power-cord is not connected.
• The power-cord of the respective
device is not connected properly or
not connected at all.
• The connection-socket or the plug is
dirty.
• The input-signal is too strong.
• The power-cord is not connected.
up • Inputs receive DC-voltage.
• Amplifier is overheated due to
impurities.
• Impedance of speakers too low
• Short-circuit in speaker connection or
in speakers
• Technical default of amplifier

• Check the power-cord and any
extension-cables.
• Check the power-cord and if the
plugs are tightly connected with the
sockets.
• Clean the socket and/or the plug.
• Reduce the input-signal via the Gain-
control.
Please check if the power is available
• Switch amplifier off and have the
device checked by a service-
technician.
• Clean the fan-grille.
• Connect other speakers.
• Check speakers.
• Switch amplifier off and have the
device checked by a service-
technician.
