designs. In fact, due to the proprietary design of the power output section, the
discontinuities visible on the distortion analysis product are much smaller than those
normally associated with crossover distortion in single supply class AB designs. These
circuit advances are clearly reflected in the superior specifications of the AUDIOPRO
3000. The AUDIOPRO 3000 may be the first high power amplifier to offer specifications
and sonic performance equal to or surpassing ultra low distortion designs such as
class-A amplifiers.
The AUDIOPRO 3000 is designed and manufactured by Yorkville Sound LTD. Each
unit undergoes a thorough, temperature cycled burn-in period, and each circuit is
tested by both manual and sophisticated computer controlled equipment which is
capable of identifying any deviation from the design center parameters. The design of
the AUDIOPRO 3000 is radical in concept but conservative with respect to the power
handling capabilities of the output devices. The topology guarantees that thermal
stress - not secondary breakdown - will set the limits of operation, while the computer
optimized heat dissipation system insures that excessive thermal stress will not occur.
Yorkville’s reputation as a manufacturer of reliable equipment will be further enhanced
by the AUDIOPRO 3000.
The AUDIOPRO 3000 was designed primarily for high power applications. It excels
at driving big systems and subwoofers to their maximum SPL, and its rugged, road-
worthy construction ensures that it will keep on doing just that - from location to location
for years to come.
The AUDIOPRO 3000 is not only suitable for use in both heavy duty touring sound
reinforcement systems but also when high headroom and ultra-low distortion are
needed to fully reproduce the dynamic range and clarity of today’s CD recordings. This
last point needs emphasis: The AUDIOPRO 3000 will drive 8 Ohm loads with better
sonic purity and lower distortion than any “listening amplifier” we know of, including
those that cost much much more. And, since the AUDIOPRO 3000 is built to survive
grueling road conditions and constant 2 ohm operation, its reliability in a fixed
installation running 4 or 8 ohm studio monitors is without parallel.
Of course, what really counts is how it sounds. Listeners have commented that the
AUDIOPRO 3000 provides the clearest most transparent reproduction they have ever
heard. You will have to judge for yourself.
