Special Design Features
High Efficiency While many contemporary amplifiers waste 50% or more of the power they pull
from the wall as heat, your SW-1 amplifier runs at approximately 90% efficien-
cy. As a result, more power is available for the loudspeaker, and less is wasted
as heat in your room.
The high efficiency of the design also means that the amplifiers can be placed in
close proximity to each other, as in an equipment rack, without undue overheat-
ing. Of course, care must be taken to account for the heat generated by other
components in the rack; but your Wisdom Audio amplifiers will not greatly con-
tribute to the thermal management challenges of your system.
Powerful EQ Wisdom Audio uses an unusual Regenerative Transmission Line™ (RTL™) design
in our subwoofers. It provides exceptional transient response, for a subjectively
“fast” and articulate bottom end which mates well to our unique thin-film tech-
nology.
However, as with most subwoofer designs, some equalization is required to
fully realize the performance potential of RTL designs. In most subwoofers, the
requisite EQ is simply built into the plate amplifier that is part of the subwoofer
itself. This approach presents a problem, however, when the subwoofer is de-
signed to be integrated into the home itself. Hence the SW-1, which allows the
subwoofer’s amplifier to be placed in the rack with the rest of the electronics,
while allowing the subwoofer to be placed wherever it will perform best, with-
out violating building codes or even having to worry about having an AC outlet
near the subwoofer location.
The SW-1 comes pre-programmed from the factory for a specific application,
whether a particular subwoofer model, or “flat” in the case of EQ being pro-
vided for elsewhere in the system (perhaps in an SC-1).
Important! Since the SW-1 comes pre-programmed for a specific model of
subwoofer, it is essential to use it only with that model of subwoofer.
Doing otherwise will almost certainly result in poor performance.
