the Sinfonia are in parallel, therefore either set may be used for
normal loudspeaker connection.
The Sinfonia is also equipped with a low-impedance
subwoofer output controlled by the volume potentiometer.
The circuitry of the Sinfonia is conceived to provide an
effective protection from short circuits which may occur at
the outputs.
CONNECTION TO MAINS
Before connecting the mains cable and switching on, make
sure that your local power supply voltage corresponds to the
value shown on the rear panel of the unit.
IMPORTANT !
Never connect the amplifier to a mains supply of a different
voltage to that shown on the unit !
Mains fuses are located in the IEC mains input socket
located on the rear of the unit. The correct value is indicated on
the rear panel and also in the technical specifications at the end
of this manual.
If you need to replace a mains fuse, always use one of the
same type and rating !
OPERATION
After switching on, the Sinfonia stands by for a time of
about 5 seconds, during which the four diodes on the front
panel are on and the outputs are disabled.
