Madrigal Imaging Mark Levinson No. 29 ユーザーズマニュアル

NEVER connect the Nº29's output terminals to any device other than a
loudspeaker.

NEVER short-circuit the amplifier output terminals.

NEVER connect the left-channel output terminals to the right-channel
output terminals.

The Nº29 is equipped with gold-plated, high-current, five-way binding
posts for output termination to a loudspeaker system. To take full
advantage of the sonic quality of the Nº29, we recommend using
high-quality speaker cable. See your Mark Levinson dealer for
recommendations.

There are two recommended methods for connecting speaker cables
to the Nº29. A high-quality spade- or hook-type lug, soldered to the
cable, is best.

Spade lug

Hook lug

We confidently 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.
However, soldering will ensure a better electrical connection.

Note: If you have no experience in soldering, see your Mark
Levinson dealer for assistance.

The "pigtail" is another method of connection which uses 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 Nº29.
