Biamplification - Mark Levinson 38S Operating Manual

Biamplification

If your system calls for multiple outputs from the Nº38S (as might be
the case for "passive" biamplification, for example), you may use
balanced Y-adaptors to split each balanced output into two
balanced outputs. The low output impedance (6 ) of the Nº38S
can easily drive multiple power amplifiers.
2 SINGLE-ENDED MAIN OUTPUTS
Single-ended ("unbalanced") outputs are provided for
compatibility with a wide range of associated components,
including 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 Nº38S 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
Nº38S 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:
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 Nº38S. If not, wire the cables so that
the appropriate output pin connects to the equivalent input pin.
4 RECORD OUTPUTS
Connect these outputs to the right-channel and left-channel tape
inputs of your recorder.
These outputs are unaffected by the OUTPUT LEVEL control on the
front panel of the Nº38S, or by the source chosen to be Monitored.

Note: If you won't be using the Nº38's balanced inputs and
need more single-ended inputs, it's possible to fabricate a
cable to connect line-level sources with single-ended output
to these balanced inputs:
