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. To
connect these cables, use a high-quality spade or hook lug soldered
or crimped to the cable with extremely high pressure.
• Connect the + (positive) binding posts on the Nº433 to positive
inputs on the associated loudspeaker.
• Connect the – (negative) binding posts on the Nº433 to
negative inputs on the associated loudspeaker.
Caution!
DO NOT OVERTIGHTEN the Nº433 binding posts. The innovative
design of these binding posts provides more leverage than more
traditional designs. Tight, high-contact pressure connections can
be achieved with finger-tightening. Special tools are not needed.
DO NOT FORCE the Nº433 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.
3. Unbalanced Input
Provides left, center and right-channel audio input. One RCA
connector per channel is available to accept unbalanced input
signals from an associated preamplifier. Unbalanced signals are
converted to balanced signals upon receipt, and processed as
balanced signals thereafter.
If the associated preamplifier does not support balanced connec-
tions, connect the RCA output on the preamplifier to the RCA input
on the Nº433. To reduce the chance of noise at the (otherwise un-
terminated) inverting XLR input, insert the supplied U-shaped
shorting-straps between pins 1 and 3. (Shorting-straps are installed
when the Nº433 is shipped.)
