NOTE
: We recommend using one of our WWK-BB2/WWK-BB3 custom high
quality balanced audio interconnect kits to ensure the best audio signal and
reliability.
The pin assignments of this XLR-type male output connector are:
These pin assignments are consistent with the standards adopted by the Audio
Engineering Society and are used with the purpose-designed SA Series power
amplifiers from Wisdom Audio. If you elect to use a different amplifier for your
woofers, please refer to the operating manual of your power amplifier to verify that
the pin assignments of its input connectors correspond to your Wisdom Audio SC-3.
If not, wire the cables so that the appropriate output pin connects to the equivalent
input pin, in order to preserve the polarity of the musical signal.
If your power amplifier does not have balanced inputs, the adapter used to convert
from balanced to single-ended must “float” Pin 3 (the inverted signal). This can
easily be checked with an ohmmeter: the impedance be- tween Pin 3 and
either the
center pin or the shield skirt on the RCA should be infinite. Tying the output of Pin
3 to ground (as some adapters do) will compromise the performance of the SC-3.
The correct wiring for converting Balanced to Single Ended for the output of the SC-
3 is shown below.
CAUTION! Note that a Balanced to Single Ended adapter for use on the output side
of the SC-3 is different than the appropriate adapter on the input side. Should you
need them, properly wired adapters are available from Wisdom Audio for a nominal
charge
RECOMMENDED: We recommend using our pre-made Custom Interconnect Kits
( WWK-CUSTOM2 and or WWK-CUSTOM3 ) for the best in audio performance and
reliability.
