Turn the volume on your preamplifier all the way down before
attempting to connect anything to your Mark Levinson
power amplifier.
1 BALANCED AUDIO INPUT
Accepts a signal from a preamplifier with balanced outputs via a high qual-
ity XLR connector. If connection to the preamplifier is made with a bal-
anced interconnecting cable, it is important to remove the shorting plugs
from between pins #1 and #3 of the XLR inputs which were placed there
prior to shipment from the factory . Save them for possible use at a later date
(should you want to listen to a friend's single-ended cable, for example).
The pin assignments of this XLR-type female input connector is:
Pin 1: Signal ground
PUSH
Pin 2: Signal + (non-inverting)
2 1
Pin 3: Signal – (inverting)
3
Connector ground lug: chassis ground
These pin assignments are consistent with the standards adopted by the
Audio Engineering Society . Refer to the operating manual of your balanced-
output preamplifier to verify that the pin assignments of its output connec-
tors correspond to your Mark Levinson amplifier. If not, wire the cables so
that the appropriate output pin connects to the equivalent input pin.
