Making the STS Connections
As with any system, you should make changes to the connections only when
the power is turned off to avoid any chance of inadvertently causing a problem
(such as a short-circuit).
We recommend using heavy-gauge speaker wire, particularly when the instal-
lation forces you to use longer wires than you might otherwise. A good rule of
thumb is to keep the “loop resistance” below 0.1 ohms.
The loop resistance can be easily measured with an inexpensive volt-ohm
meter. Simply twist the two conductors at one end of the cable together, and
then measure the DC resistance across the two conductors at the other end of
the speaker wire. Doing this measures the total resistance going down one side
and back the other, hence the term “loop resistance.” If this figure is at or below
0.1 ohms, you are in good shape.
For the purposes of this manual, we will assume that you have already con-
nected the SC-1 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-1; following the SC-1, the signal for the sub-
woofer is sent to a high quality amplifier such as the Wisdom Audio SA-series
amplifiers.
Connect the outputs of your amplifier to the subwoofer, taking care to get the
polarity correct. Connect the positive (+) terminals on your amplifier to the posi-
tive (+) terminals on the STS; likewise, connect the negative (–) terminals on the
amplifier to the negative (–) terminals on the STS.
