Making the S90 Connections
(Continued)
For the purposes of this manual, we will assume that you have already connected
the SC-2/3 System Controller as per the instructions found in its manual. As such,
you should have signal coming from your source component(s) to a
preamp/processor that provides bass management (to create the subwoofer
channel(s), and then on to the SC-2/3; following the SC-2/3, the signal for the sub-
woofer is sent to a high quality amplifier such as the Wisdom Audio SA Series
amplifiers.
A “pigtail” connection is provided at one end of the S90. Since the S90 fills a
standard 2 x 6 stud bay, the simplest thing is to drill a hole in one of the 2 x 6 studs
and thread the pigtail through to the adjacent bay, where you have ample room to
make connections and run the wires.
Alternatively, the incoming signal can be routed directly into the small space
provided by the “feet” of the S90, and the connection to the pigtail can be make
just prior to installing the S90 in the wall.
Connect the outputs of your Wisdom Audio SA-series amplifier to the subwoofer,
taking care to get the polarity correct. Connect the positive (+) terminals on the SA-
Series amplifier to the red wire in the pigtail; likewise, connect the negative (–)
terminals on the amplifier to the black wire in the pigtail.
We recommend using wire nuts and then wrapping the resulting connection in
electrical tape to preclude any chance of the wire nut working loose over time.
