Speaker connections

NEVER connect the Nº27.5's output terminals to any device
other than a loudspeaker.
NEVER short-circuit the amplifier's output terminals.
NEVER connect the left-channel output terminals to the right-
channel output terminals.
The Nº27.5 is equipped with gold-plated, high-current, five-way
binding posts for output termination to a loudspeaker system. To take
full advantage of the Nº27.5's sonic quality, we recommend using
high-quality speaker cable; see your Mark Levinson dealer.
There are two recommended methods for connecting speaker cables
to the Nº27.5. A high-quality spade lug or hook lug, soldered to the
cable, is best.
Spade lug
We recommend Madrigal binding post lugs, made of oxygen-free
copper with gold-over-silver plating. These lugs are available for round
cable; see your Mark Levinson dealer for more information.
Many lug connectors are designed to be crimped onto the cable.
Soldering, however, ensures a better electrical connection.
Note: If you have no experience in soldering, see your Mark
Levinson dealer.
The "pigtail" is another method of connection, using a short piece of
14-gauge wire soldered to the speaker cable. The other end of this 14-
gauge wire is inserted through the hole in the five-way binding posts
on the rear panel of the Nº27.5.
1. Begin with 3" of 14-gauge copper wire.
2. Strip 5/8" of insulation from one end, and strip 1/2" of insulation
from the opposite end.
