D-CAT PATENT ISSUES

ISP Technologies is proud to announce the first patent covering the D-CAT™ power amp technology has issued. The D-CAT™ (Dynamic Current Amplifier Technology), an innovative approach invented by James “Buck” Waller and Derek Bowers, 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 with no trim measurements and 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.

The D-CAT amps are used exclusively in ISP Technologies, Inc. products, including the Professional Audio gear, the Vector Cabinets, the Theta Head and the Vector SL Guitar Subwoofer.
