ISP Technologies is proud to announce the patent pending
D-CAT™ power amp technology. Using an innovative approach
invented by James “Buck” Waller and Derek Bowers, the D-CAT™
(Dynamic Current Amplifier Technology) is an amazing
departure from “traditional” power amp technology.
In a typical, or traditional, power amp, there are many
components that can fail. The first potential for trouble is
in the factory when someone has to calibrate a trim pot that
will set the bias for the output section. The second trouble
spot can come into play when the power amp is used over time
and the bias trim adjustment can drift or become open
circuit. Both scenarios can be detrimental and in the latter
case cause the destruction of the output devices.
The beauty of the D-CAT technology is in its simplicity.
Using state of the art monolithic circuitry, a PCB is
assembled and that’s it…no trim measurements, nothing to
drift or change bias down the road. The D-CAT also provides
extremely high output current, easily driving a 1/2 ohm to 1
ohm load. Most power amps currently on the market have a
hard time driving 2 ohms and seldom offer 1 ohm stability.
The D-CAT is capable of delivering 4 to 5 times as much
current to the load as other typical power amps.
Because there is absolutely no bias in the output section of
the D-CAT, no bias trim adjustment is required, leading to
increased reliability, stability, and no bias in the output
section eliminates any possibility of thermal runaway. The
higher reliability and efficiency leads to a huge reduction
in cost per watt. Another added benefit of the D-CATs’
higher current output is a major increase in transient
response, which greatly increases the sonic punch at low end
and makes for a better overall sound experience.
Currently reviewing the D-CAT technology for potential
future products are: Dell Computer, Compact, IBM, Hewlet-Packard,
Polk Audio, Delphi, Sirius Radio, and Audi. For more
