full advantage of the amplifier’s sonic quality, we recommend using high-
quality speaker cable; please see your Wisdom Audio dealer.
Caution! NEVER connect a power amplifier’s output terminals to any device
other than a loudspeaker.
NEVER short-circuit the amplifier’s output terminals.
NEVER connect the output terminals of one amplifier to the output
terminals of another amplifier.
Each channel of the SA-3 system amplifier has a single, patented Cardas
speaker terminal for making the speaker wire connections. This system
uses a single large knob to tighten down on both positive + and negative –
connections at once, without any need for tools.
The unique design of these binding posts allows the use of a strong, hard
material for the threads that provide the pressure on the connection, while
at the same time using optimal electrical connections (which require a
softer metal). By separating the mechanical and the electrical systems
within the connector, both can be properly optimized.
There are two recommended methods for connecting speaker cables to
your amplifier. Either a high-quality spade lug or hook lug, soldered to the
cable (or crimped with extremely high pressure), is best.
Connect the + (positive) output post of the amplifier to the + (positive)
input terminal of the appropriate loudspeaker. Connect a – (negative or
black) output post of the amplifier to the – (negative or black) input ter-
minal of the appropriate loudspeaker. Take care to maintain this proper
polarity throughout the system.
Caution! DO NOT OVERTIGHTEN the binding posts on your amplifier! The
unique design of these posts gives far more leverage than traditional
posts. You will achieve tight, high contact pressure connections with
only modest finger-tightening, and without having to resort to special
tools.
