CA Series
Power Amplifiers.
Our most
efficient amp
series yet!
D-MAX Class D
technology,
Dynamic Power
Factor Correction,
and SailFlow
cooling.
-MAX Class D technology
and Dynamic Power Factor
D
Correction make our CA series
the most efficient amplifiers we
(or anyone else) have offered
% more efficient than one of
our most popular competitors.
Efficiency definitely counts
when the electrical power bill
comes. But our CA Series have
another advantage over other
amps of the same power: you
can run any TWO CA’s on a
single 20-amp line. If your proj-
ect needs two amps, you don’t
have to call a $100/hr electrician to add a second 20-amp
feed.
CA amps sound superb
even when driven hard and stay
cooler than most, thanks
to straight-thru, unimpeded
SailFlow cooling.

CA Series
shly’s proprietary D-MAX™
A
technology takes Class D performance and efficiency to a whole
new level. By starting with a clean
slate, our engineers were able to
apply cutting-edge design practices
and state-of-the-art components to
the most efficient amp we’ve tested
thus far.
The pay-off is less heat, lower
distortion, more stable operation and
greater reliability. Bulky heat sinks
are no longer required. Instead, we
optimized active air cooling using our
newly developed SailFlow™ design,
which moves the air along a selective
path, to where it’s needed most.
Coupled with our ultra-high-speed
switching power-supply and intelligent power management, all the
transient impact and spatial detail
of your sound is preserved and your
speakers will never be happier.
Light-weight and power-efficient,
CA will never pull more power than
your wall outlet delivers. No more
worry about driving speakers to
the brink of destruction or tripping
breakers.
