The New Zapco Z-Series Amplifiers; The Re-Birth Of The Z-Series - zapco Z-150.4 II Owner's Manual

The New Zapco Z-Series Amplifier
Congratulations, on the purchase of your new Zapco Z-Series amplifier. We
believe you now have the finest sound available in a car sound amplifier, and we
think you should know a little bit about what makes this amp unique in a world
of so many so-so products.

The re-birth of the Z-Series

In 2012 Zapco introduced the new Z-Series of SQ amps. These amps were not
conceived so much by our engineers, as by input from audiophiles and car sound
fanatics around the world. Starting about 2004, at Zapco training seminars in
Asia and in the EU, we began running into audiophiles who were changing
certain internal components in our amplifiers to achieve what they felt was
better quality sound.
With that in our minds, we developed the Z-Series amps with less measuring
and more listening. So for the Z-Series of Zapco amplifiers, we experimented
with internal components and new circuits to see if we could take our amps to
the next level of sound quality by investing in different internal components
and circuit designs, and the resulting Z-Series amps were the results of this
unique development method.
Over the last years we have developed two specialized amplifiers to take auto
sound to a different level. The Z-Series LX amp, the ultimate SQ amp. No controls
except gain. A pure SQ amp. We also brought out the ZSP-Series amps for the
fanatics that want to play full-volume full-time but still get audiophile sound.
This year we stepped back and took a look at the amp that started it all. The
Z-Series amplifier. We knew we could bring the price down, because over the
last few years. This allowed us to build the Z-series LX and amps cost only a
little more than the original Z-Series so the prices weren't that far apart. Now
we have brought the Z-Series into the same plant as the newer models. This
saves money!
That lowers the price, but what could we do the make it better? We saw that a
lot of the non-critical parts from the LX and amps could used in the new Z-Series
as well. Even with some of the SQ parts we save by buying more so we can use
those in the Z-series also.
