Input Connectors
One balanced and one single-ended (unbalanced) connector is
available for each audio channel input.
Ground switch: A small toggle switch selects the grounding
appropriate for either the balanced (XLR) or single-ended (RCA)
input connector(s). Make sure the toggle switch is set all the
way to the position closest to the connector you are using.
The switch does not select the connectors; it only changes the
grounding to suit the selected connector.
BALANCED INPUT
SINGLE-ENDED INPUT
Balanced analog input connectors: these connectors accept
left-channel and right-channel balanced input signals from
a line preamplifier or other source with balanced (male XLR)
output connectors.
Balanced connector pin assignments:
• Pin 1: Signal ground
• Pin 2: Signal + (non-inverting) "hot"
• Pin 3: Signal – (inverting) "cold"

Single-ended input connectors: these connectors accept left-channel
and right-channel single-ended (unbalanced) input signals from a line
preamplifier or other source without balanced output connectors. Mark
Levinson recommends using balanced connections whenever possible.
Output Connectors
Binding Posts: The amplifiers utilize custom-made, gold-
plated, high-current loudspeaker binding posts. The positive
binding posts, labeled + (positive), are red; the negative binding
posts are black and are labeled – (negative).
Two of each binding post are present on each channel. For most
setups, connect one of the positive and one of the negative
terminals per channel to the respective loudspeaker terminals.
The additional binding posts enable optional bi-wiring for
compatible loudspeakers. If your loudspeakers support bi-
wiring, connect both red (positive) terminals to the red terminals
on the loudspeaker, and connect both black (negative) terminals
to the black terminals on the loudspeaker.
If your loudspeakers do not support bi-wiring or you prefer not
to employ this connection configuration, simply connect one of
the positive and one of the negative terminals to the respective
loudspeaker terminals. There is no additional configuration
needed to disable bi-wiring output capability.
Banana plugs can also be used to connect the speaker cables
to the loudspeaker binding posts. The banana plug connections
are covered on European models due to safety regulations.
NOTE: Ensure when connecting the loudspeaker that at
least one positive and one negative binding post is used.
Caution!
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.
Caution!
DO NOT OVERTIGHTEN the binding posts. The innovative
design of these binding posts provides more leverage; hence,
high-contact, tight pressure connections are achieved when
finger-tightened.
DO NOT FORCE the binding post "wings" over a bent or
oversized connector. Doing so may damage the binding post.
