Mission Statement
Committed to excellence
Zapco is dedicated to the pursuit of audio fidelity. Our prime objectives are to
design and manufacture audio products of unsurpassed quality, to provide
unparalleled support and service for these products, and to conduct business in a
manner that will enhance the quality of life for all involved.
Experience: Knowledge from doing
There is absolutely no substitute for experience; that is a simple fact of life.
Another simple fact is that Zapco has, for over forty years, been the leader in
defining quality standards for the car audio industry. These years of experience
have led to a thorough understanding of the challenges that are unique to the
world of car audio. Zapco's relentless quest for sonic purity consistently yields
imaginative designs that utilize the most innovative technologies. The resulting
products set the criteria by which all others in the industry are judged.
The Zapco Z-Series
The Z-Series of Zapco amplifiers is the result of our experience over the last 40
years with the technology of sound reproduction, combined with what we have
learned in consultations with the home and car audiophile communities over the
last few years about human perception of sound. We have also used a number of
studies of the human physiology to examine what an amplifier should do to make
reproduced music sound more like live music.
What did we discover? The proper combination of output devices, op-amps,
capacitors and other internal components makes a huge difference in the quality
of the sound an amplifier produces. We also determined that with technological
advances over the last 10 years we could now develop a more efficient Class D
amplifier that would have the SQ specs at 1Ω to equal or even surpass those of
most A/B amps.
What we did: We set our standards for specifications in Class A/B and Class D and
assured that all amps would meet them. Then we used the best combination of
tantalum capacitors, NJM 5532L and OPA 2134 op-amps, KEC and Sanken high speed
bi-polar output devices Calss A/B ampsand MOSFET output devices for the Class D
amplifiers to produce what we believe are the best sounding amplifiers we have ever
made.
Great sounding Class D? Yes indeed! Class D with less than 0.5% THD at full
power! Class D with damping over 350 at 1Ω. (That's the same as an A/B amp with
damping of over 1,400 at 4Ω!) Class D with a S/N ratio of 90dB.
What's it all mean? Clear, sharp, earth shaking bass that won't go soft and muddy
at high volumes. If your speaker can handle it, these amps can produce it
