Intended Use
The Fidel Power Amplifier 2x 500 W serves to amplify low-level audio signals in semi-
professional respectively professional audio systems and is interposed between the
signal source to be amplified and the loudspeakers.
The power amplifier is designed for loudspeakers with a minimum impedance of 4
Ohm. The appliance may only be used with a low-level audio source.
The product may only be connected to 230V~/50Hz (10/16 A) AC voltage and an
earthed wall socket.
Use is only permitted in closed rooms, meaning not out in the open. The contact with
moisture, e.g. in bathrooms and similar rooms has to be avoided at all cost.
Another use than the one described above leads to damages to the product and is
also associated with dangers like short circuit, fire, electric shock, etc. The entire
product may not be altered respectively modified and the casing may not be opened.
The safety notices have to be observed under all circumstances!
