Mark Levinson

Audio Channel Inputs
One balanced and one single-ended (unbalanced) connector is
available for each audio channel input.
Single-Ended Inputs
The RCA connectors accept single-ended signals from preamplifiers
with singled-ended (RCA) outputs. A small toggle switch is
provided to select either the balanced (XLR) or single-ended (RCA)
input connector on each channel.
If your preamplifier does not support a balanced connection to the
power amplifier, connect the single-ended output to the RCA input
on the amplifier. Make sure the toggle switch is set to the position
closest to the RCA connector.
Balanced Inputs
Accepts a signal from a preamplifier with balanced outputs via the
high quality XLR connector. Make sure the toggle switch is set to
the position closest to the XLR connector.
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 power
amplifier. If not, wire the cables so that the appropriate output pin
connects to the equivalent input pin.
The Nº531H, 532H and 533H utilize custom-made, gold-plated,
high-current loudspeaker binding posts, two for each output
channel. The Nº535H uses different high-current binding posts
due to space constraints. The positive binding posts, l
(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.
Be careful to not short the positive and negative outputs
together. Do not short the positive or negative outputs to chassis
or any other safety ground. The amplifier must be powered off
during installation and whenever input and/or output cables are
being connected.
