5 SPEAKER BINDING POSTS
The Mark Levinson 300-series amplifiers are equipped with custom made,
gold-plated, high-current binding posts for output termination to a loud-
speaker system. To take full advantage of the amplifier’s sonic quality, we
recommend using high-quality speaker cable; please see your Mark
Levinson 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.
There are two recommended methods for connecting speaker cables to
your amplifier. A high-quality spade lug or hook lug, soldered to the cable
(or crimped with extremely high pressure), is best.
Spade lug Hook lug
Connect a + (positive or red) output post of the amplifier to the + (positive
or red) input terminal of the appropriate loudspeaker. [If biwiring, repeat
using the other + (positive or red) output post of the amplifier and the +
(positive or red) input terminal of the loudspeaker.]
Connect a – (negative or black) output post of the amplifier to the – (nega-
tive or black) input terminal of the appropriate loudspeaker. [If biwiring, re-
peat using the other – (negative or black) output post of the amplifier and
the – (negative or black) input terminal of the loudspeaker.]
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.
DO NOT FORCE the “wings” up and over a bent or oversized
connector, as this may damage the binding post. If your
connectors obstruct the turning of the “wings,” slide them into
place when the binding post opening is a snug fit; then apply
a final quarter-turn as needed to tighten the connection.
