Mark Levinson N380S Owner's Manual page 13

If your system calls for multiple outputs from the Nº380S (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 Nº380S can easily drive multiple power am-
plifiers.
2 SINGLE-ENDED MAIN OUTPUTS
Single-ended ("unbalanced") outputs using Madrigal-designed RCA jacks are
provided for compatibility with a wide range of associated components, in-
cluding power amplifiers and electronic crossovers.
If you use the single-ended outputs, connect them to the corresponding
inputs of your power amplifier (or other device). Note that special features
of the Nº380S enable it to be used optimally with a surround sound pro-
cessor as one of its inputs. We do not recommend having a surround
sound processor follow the Nº380S in the signal path. (For more informa-
tion, see "Using Surround Sound Processors.")
3 BALANCED INPUTS 1 AND 2
Accepts right-channel and left-channel balanced signals from source equip-
ment with balanced outputs.
The pin assignments of these XLR-type female input connectors are:
PUSH
2 1
3
Refer to the operating manuals of your balanced-output line-level sources
to verify that the pin assignments of their output connectors correspond to
the Nº380S. If not, wire the cables so that the appropriate output pin con-
nects to the equivalent input pin.
Note: If you won't be using the Nº380S' balanced inputs and need
more single-ended inputs, it is possible to fabricate a cable
to connect line-level sources with single-ended output to
these balanced inputs:
Pin 1: Signal ground
Pin 2: Signal + (non-inverting)
Pin 3: Signal – (inverting)
Connector ground lug: chassis ground
