Featuring robust power,
efficient operation, impressi-
ve specs, and excellent cost per
watt performance: Kempton’s
KA amplifiers are the perfect
power mates for PW and GT
sound reinforcement speaker
systems. Used in 4-ohm bridged
applications the KA 2000 deli-
vers 2000W, the KA 1200
1200W and the KA 800 800W.
The KA Amplifier Series is the
result of many hours of testing
and performance involving
Kempton’s tech staff and users.
The results are a sophisticated
power amp circuit design featu-
ring high power, superb quality,
reliability and stability to provide
the highest possible sound
performance
Amps with Class
KA 800 and 1200 are feature Class AB design,
while KA 2000 is a Class H (2 steps) amp design.
The KA Series power amps deliver high fidelity
sound quality, high slew rate, wide full range fre-
quency response and extremely low noise. These are
the references of Kempton’s KA Power Amplifiers.
Features & Controls
Sophisticated protection circuits prevent improper
tampering. A variable low noise, high speed fan pro-
vides for improved heat dissipation and to prevent
thermal shutdowns. Balanced XLR and Jack input
connectors. Professional 4-pin speakon and binding
posts outputs. Stereo-Parallel-Bridge modes via
switch. Selectable clipping control / limiter function
switch. Selectable built-in 30Hz low pass filter to
protect speaker systems from damage caused by
subsonic frequencies. LED indicators for the output
balance, as well as LED status indicators of signal
(SIG) and clipping (CLIP). 2-unit 19” rack space desi-
gn for universal rack mount installations.
