Note

One balanced and one single-ended (unbalanced) connector is available for each audio channel input.

Single-Ended Inputs

These RCA connectors accept single-ended input from preamplifiers with singled-ended (RCA) outputs. Single-ended input signals are converted to balanced signals at the input stage of the amplifier, and are handled as balanced signal thereafter.

If your preamplifier does not support balanced connection to the power amplifier, connect the single-ended output to the RCA input on the amplifier. To reduce the chance of noise pickup at the (otherwise unterminated) inverting input of the XLR, insert the provided U-shaped shorting strap between pins #1 and #3 of the XLR connector. The shorting strap is installed at the factory.

Balanced Inputs

9

 

Accepts a signal from a preamplifier with balanced outputs via the high quality XLR connector. Before connecting to the XLR connector on the rear panel of the power amplifier, verify that the shorting straps between pins #1 and #3 of the XLR input connectors are not in place. If you need to remove the strap, be sure to save them for future use as these straps must be in place when using the single-ended RCA connectors to reduce noise pickup.

The pin assignments, shown on the left, of the XLR-type female input connector are consistent with the standards adopted by the Audio Engineering Society. Refer to the operating manual of your preamplifier to ensure that the pin assignments of its balanced output connectors correspond to the Mark Levinson Nº532 power amplifier. If not, wire the cables so that the appropriate output pin connects to the equivalent input pin.

The Nº532 has four custom-made, gold-plated, high-current loudspeaker binding posts, two for each output channel. 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.
