Mark Levinson 380 Owner's Manual page 15

Refer to your power amplifier's operating manual to verify that
the pin assignments of its input connectors correspond to the
Nº380. If not, wire the cable so that the appropriate output pin
connects to the equivalent input pin.
Connect the right-channel and left-channel
puts of the Nº380 to the appropriate balanced inputs of the power
amplifier.
If your system calls for multiple outputs from the Nº380 (as might
be the case for "passive" biamplification, for example), you may
use balanced Y-adapters to split each balanced output into two
balanced outputs. The low output impedance (6 ) of the Nº380
can easily drive multiple power amplifiers.
2 Single-Ended Main Outputs
Single-ended ("unbalanced") outputs using Madrigal-designed
RCA jacks are provided for compatibility with a wide range of as-
sociated components, including power amplifiers and electronic
crossovers.
If you use the single-ended outputs, connect them to the corre-
sponding inputs of your power amplifier (or other device). Note
that special features of the Nº380 enable it to be used optimally
with a surround sound processor as one of its inputs. We do not
recommend having a surround sound processor follow the Nº380
in the signal path. (For more information, see "Using Surround
Sound Processors.")
3 Balanced Inputs 1 and 2
Accepts right-channel and left-channel balanced signals from
source equipment with balanced outputs.
The pin assignments of these XLR-type female input connectors
are:
Pin 1: Signal ground
PUSH
Pin 2: Signal + (non-inverting)
2 1
3
Pin 3: Signal – (inverting)
Connector ground lug: chassis ground
Refer to the operating manuals of your balanced-output line-level
sources to verify that the pin assignments of their output connec-
tors correspond to the Nº380. If not, wire the cables so that the
appropriate output pin connects to the equivalent input pin.
