Setting Up the SCS
The unusual form factor of the SCS allows it to be used effectively in many situ-
ations where a more conventional “bass cube” would be either cumbersome
or impossible. Examples include locating it behind a couch, in the small space
between the couch and the wall, or laying flat under a set of risers in a home
theater with multiple rows of seating.
The SCS also includes three locations for the exit of the Regenerative Transmis-
sion Line
™ . As shipped from the factory, the vent is located on the end of the
SCS enclosure. However, if your location would be better served by the vent
being on one side or the other, your dealer can easily swap the grille for the
solid aluminum plate that covers the desired exit location. There is no difference
in performance, but often a great difference in application flexibility.
Using the Wisdom Audio SC-1 When using the SCS with the SC-1 System Controller, connect the appropri-
ate Sub Output of the SC-1 to the balanced SSP/Direct input of the SCS. Then
calibrate the system as usual, using Wisdom System Configuration and Audyssey
MultEQ Pro.
Using a Surround Processor When using the SCS in a multichannel system with a surround preamp/proces-
sor, connect the appropriate Sub output from the SSP to the SSP/Direct input.
Calibrate the system as you normally would, following the directions provided
by the owners’ manual for the surround processor. The internal crossover and
level controls of the SCS are bypassed when using this input, so your surround
processor has complete control over what the subwoofer is given to do.
Using a Stereo Preamplifier The somewhat tricky setup is when you use the SCS (or any subwoofer, for that
matter) with a traditional stereo preamplifier that lacks any of the bass manage-
ment capabilities found in surround processors.
As a reminder, you should run both the Left and Right channel, full-range sig-
nals to the SCS, using the Left and Right inputs, respectively. This can be ac-
complished either by using a second set of outputs from your preamplifier, or
by using a pair of Y-adapters to split each channel into two identical copies (the
other of which goes to the main amplifier for your regular speakers).
Optimizing the system in such cases involves a bit of trial and error, but it is usu-
ally a fairly interesting and pleasant experience. The goal is to achieve a smooth
transition from the SCS to your main speakers that is seamless.
If you have a high resolution RTA (real time analyzer) and some pink noise, you
can “rough in” the settings fairly quickly. But even so, you will want to do the
final adjustment by ear, using music as your guide.
Find some music that has consistent energy in the 40-80 Hz octave. (An acous-
tic recording of a solo upright bass player works well). Then:
