Caution!

Mark Levinson

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.

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.)
