System Configurations
The following pages show some typical
connections that you might make in your installa-
tion. They show how the inputs and outputs of
the Classic preamplifier are connected to
various audio components.
If your turntable is equipped with a Moving
Magnet cartridge, connect its audio outputs to
the preamplifier’s Moving Magnet inputs as
shown. Make sure that the MM/MC button is
in the OUT position.
If you have a Moving Coil cartridge, use
the preamplifier’s Moving Coil inputs and push
the MM/MC button inwards.
System Configurations
In most cases, the turntable ground wire
should be connected to reduce any hum
heard in the speakers.
Never connect a line-level source compo-
nent directly to the preamplifier’s MC or MM
inputs as they will be overloaded. They are
specially designed to handle only the very low
level outputs from a phono cartridge, and not
the higher voltage outputs from CD players or
other line level components. (Phono level is
usually below 100mV, whereas line level can
be up to 2 volts).
