Outputs
These 16 balanced audio outputs carry the room-corrected
full-range
,
high-pass
,
and or low-pass portion of the audio spectrum and must be connected to the
amplifiers that drive the loudspeakers and or subwoofers.
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-
2. 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-
