First, establish the AC – power connection. The
IEC mains input (Figure 2) is located on the rear
panel. Make sure that the AC mains switch is set
to (0) = OFF. Connect the power cord to the IEC
mains input and plug it into your wall outlet or
high quality power strip.
ALLEGRO offers two inputs; one balanced and
one in single ended configuration. The toggle
switch is used to select the chosen input. When
you have a choice, a properly implemented
balanced connection will offer higher sound
quality than a single-ended connection. The
amplifier can be driven by a preamplifier or
directly from a line – level source that has a
volume control.
Connect your loudspeakers to the amplifier. The
speaker cable can be connected via spade
plugs or via banana plugs. Before turning the
amplifier on, make sure that all cables have
been connected firmly and in correct polarity.
