5. loudspeaker binding posts (outputs)
Provide audio output. Two pair of custom-made, gold-plated,
high-current binding posts labeled + (positive) and – (nega-
tive) are included. Positive binding posts are red; negative
binding posts are black.
These binding posts are designed to facilitate high pressure,
high contact area connections without the use of tools such as
nut drivers. A simple finger-tightening actually yields higher
contact pressure than traditional hex binding posts. There is
no need to exert unusual effort when tightening.
Caution! NEVER connect power amplifier outputs to any component
other than a loudspeaker.
NEVER short-circuit power amplifier outputs.
NEVER connect power amplifier outputs to another power
amplifier’s outputs.
For best performance, use high-quality loudspeaker cables
with either spade or hook lugs.
• Connect the + (positive) binding posts on the Nº33H to
positive inputs on the associated loudspeaker.
• Connect the – (negative) binding posts on the Nº33H to
negative inputs on the associated loudspeaker.
Caution! DO NOT OVERTIGHTEN the Nº33H binding posts. Tight, high-
contact pressure connections can be achieved with finger-tight-
ening.
DO NOT FORCE the Nº33H binding post “wings” up and over a
bent or oversized connector. Doing so may result in binding
post damage. If the connector obstructs “wing”-turning, slide it
into place when the binding post opening provides a snug fit.
Then, use quarter-turns to tighten the connection as needed.
