Madrigal Imaging N38 Stereo Amplifier User Manual

If your system calls for multiple outputs from the Nº38 (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 Nº38
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 Nº38 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
Nº38 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
Pin 2: Signal + (non-inverting)
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
connectors correspond to the Nº38. If not, wire the cables so that
the appropriate output pin connects to the equivalent input pin.
Note: If you wont be using the Nº38s balanced inputs and
need more single-ended inputs, its possible to fabricate a
cable to connect line-level sources with single-ended output
to these balanced inputs:
1
2
3
Male RCA
(connect to source)
Male XLR
(connect to Nº38)
22-gauge
buss wire
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 Nº38, or by the source chosen to be Monitored.
