KAPPA® AMPLIFIERS
Infinity® Kappa® Series car loudspeakers
have long delivered sound quality that
rivals the best home audio systems.
Now Infinity engineers close the loop
with a new line of slim-profile,
high-output amplifiers worthy of the
Kappa name. With a choice of subwoofer,
4-channel and total-system units, all
with advanced power technology,
noise-canceling circuitry and plenty of
sheer muscle, there’s a Kappa amp for
every car, SUV, truck and musical taste
out there.

CLASS D/DIRECTFET® TECHNOLOGY
Kappa amps feature high-power Class D
circuit topology with DirectFET
transistors, a design that increases power
output and overall efficiency, with
improved heat transfer from the
transistors to the chassis. So you enjoy
better performance from significantly
smaller amps.
DYNAMIC BASS OPTIMIZATION (DBO)
Available on Kappa One and Kappa Five
amps, DBO is a proprietary variable
subsonic filter with variable bass boost.
Unlike conventional fixed-frequency
filters, DBO conserves power at
frequencies below 100Hz, protecting
woofers in vented-box applications from
overexcursion, and flattening response
through the lowest octaves in sealed-box
and infinite-baffle applications.

OISE-CANCELING SIGNAL INPUTS
Kappa amps use differential-signal
inputs with high common-mode noise
rejection for all speaker-level and
line-level outputs from source units.
Because noise from the vehicle’s
alternator and other electrical
components is radiated into the
positive and negative leads of each
signal input equally, amplifying the
difference between the leads
effectively cancels out the noise,
leaving only the music.
NONSTOP THERMAL PROTECTION
As you’d expect, Kappa amps feature smart
circuitry to protect your speakers in the
event of short circuits or problems with
your battery, alternator or voltage regulator.
But Kappa amps also protect themselves
against excess heat, with circuits that
cool the amplifier down by gradually
reducing output without shutting it down
completely. So the music never stops, no
matter how hot things start to get.
ULTRALOW-PROFILE DESIGN
At just 1-3/4" high, Kappa amps will fit
under most seats. Or virtually anywhere
else that’s convenient.
