CONNECTING INPUTS AND OUTPUTS
Situated on the rear panel of the Preludio are the input and
output sockets.
IMPORTANT !
Ensure that all other items of equipment to be connected to
the amplifier are switched off before making the
connections.
Do not insert the amplifier AC mains cord until all input
and loudspeaker connections are securely made.
To avoid the possibility of hum and noise, it is good practice
to ensure that all connections to and from the amplifier are
clean and tight, and that all cable runs are neat and tidy.
For best results, AC mains cables should not be placed
alongside signal or loudspeaker cables.
Using RCA phono interconnects of suitable quality, connect
the various sources (CD, tuner, phono) to the corresponding
inputs of the amplifier.
Remember when connecting the loudspeaker cables to the
amplifier output terminals to respect the correct phase (red =
+/black = -) for each channel.
The Preludio is also equipped with a low-impedance
subwoofer output controlled by the volume potentiometer.
The circuitry of the Preludio is conceived to provide an
effective protection from short circuits which may occur at
the outputs.
