Loudspeaker Binding Posts

Note

Caution!

Mark Levinson

The Nº53 has two pairs of custom-made, gold-plated, high-current “hurricane” loudspeaker binding posts; each pair connected directly to the output of the amplifier. The positive binding posts, labeled + (positive), are red; the negative binding posts are black and are labeled – (negative).

Ensure when connecting the loudspeaker that at least one positive and one negative binding post is used. There is NO ground reference.

Banana plugs can also be used to connect the speaker cables to the binding posts via the banana-plug sockets. Banana-plug sockets are not available for some models.

DO NOT OVERTIGHTEN the binding posts. The innovative design of these binding posts provides more leverage, ensuring that high-contact, tight-pressure connections are achieved when finger-tightened.

DO NOT FORCE the binding-post “wings” over a bent or oversized connector. Doing so may damage the binding post.
