Reality Check - zapco DSP-Z8 IV II Owner's Manual

The Zapco DSP-Z8 IV II Series
DSP-Z8 IV II Digital Signal Processor and ADSP-Z8 IV-8 Amplifier/Processor
Congratulations on your purchase of this new Zapco DSP-Z8 IV II series product. It has been
designed and built to give you many years of reliable, industry leading performance and true
audiophile level sound quality.
Zapco Introduced the world to full function in-car digital processing in 2004 with the Zapco
DSP-6 and the Zapco Digital Processing Network. This was the first full function DSP for the
car and included a full line of amplifiers with full function digital processing build right in.
In 2016 we brought out our fourth generation of processing in the Zapco DSP-Z8 IV. The Z8
IV was a mid-priced unit designed to bring audiophile processing in an affordable package,
and it did just that. The Zapco DSP-Z8IV met rave reviews, out performing DSPs costing twice
as much, with a straightforward, easy to navigate interface so tuning would be a breeze, and
an analog signal to noise of -106dB (-110dB Digital).
The new DSP-Z8 IV II series processing takes the IV to a whole new level. Sonically the DSP-
Z8 IV II has all the qualities of the original IV with an even lower noise floor. For advanced
tuning possibilities the VI II has a much-improved GUI with many important upgrades.
In addition, for all those who need everything in a very small package, the DSP-Z8 IV II series
bring all this great processing to the ADSP-Z8 IV-8, an eight-channel full range Class D
amplifier with 80 Watts RMS per channel, at 4 ohms. That puts the Z8 IV II processing and an
8-Channel amplifier in a single convenient one-box installation.

Reality Check

The automobile is a difficult environment for listening to music. There are reflective surfaces
that distort the sound, absorptive surfaces that impede it, and you are never in the ideal
listening position. The Z8 IV II processing will allow you to compensate for the shortfalls of the
auto environment to create the live listening experience. However, we highly recommend
that you engage the services of a professional installer experienced in system tuning as a
final step. A professional tuner will have many hours of experience in system tuning and the
necessary tools, like a Real Time Analyzer and distortion analyzer to see how the sound waves
are acting in your vehicle. With the proper tools and experience a professional can tell what
frequencies to boost, which to cut, and what other minor tweaks are needed to get the best
live musical experience from your car.
