Class D for the Audiophile
We saw our first Class D amp in 1975. Numerous companies have
been trying since then to design and build a full range Class D, with very
little success. Class D amps have had so much noise and distortion that
they destroy mids and highs. Even when used strictly as bass amps
they’ve been dangerous. Competitors who use class D amps in SPL cars
invariably blow out all their woofers when they hit those high numbers.
This happens because of the extreme distortion the class D amps have
been putting out when they’re driven hard. This may be acceptable to
professional competitors, who get their speakers for free, but for the non-
competitor who has to pay for them out of their own pocket, it can be a real
nightmare. Not to mention that most of us want to be able to listen to
music in our cars and need an amp that sounds great on everything, not
just woofers.
Welcome to ZAPCO’s world! Where dreams of Class D power, and full
range sound quality come true.
The ZAPCO C2K 9.0XD is the ultimate car audio amp in so many
ways. The first, of course is power. With over 2000 watts RMS into either 2
Ohms or 4 Ohms, and a chassis only 18” long, it’s easily the most powerful
amp of its size. But that’s only the start of the story. The 9.0XD has the
most advanced microprocessor control system ever offered in a car audio
amplifier. This amp has a serial port that allows it to talk to other amps, to
a PC, or even to your car. It can be programmed to control its own power
output and clipping levels. The microprocessor system in this amp will be
the heart of our new systems as we move into the realm of full digital, from
source to speaker output. With all of it being brought to you by ZAPCO.
When you’re ready for the ultimate in car audio, ZAPCO has your
product.
