A Word About “Weighted” Specifications; Stereo Separation; Results - zapco Reference Series 2 User Manual

Stereo Separation:

The ability of an amplifier to maintain the separation between the
right and left channels is what allows an amplifier to reproduce an accurate
sound stage. Music is recorded with each instrument in its own location on a
sound stage. You should hear it the same way in your vehicle.

To assure that no ZAPCO product ever fails to meet our level of
expectation, we must build all products to exceed our specifications by a
comfortable margin. Our superior design and construction give our
amplifiers advantages that go beyond power output and provide a sound
quality difference you will hear the moment you turn your system on.
A WORD ABOUT "WEIGHTED" SPECIFICATIONS
Most of the time, when you see specifications, they will be preceded
by the term "A" weighted. "A" weighting is a way of coloring numbers to
make specifications look better.
About the only place you can find specs that aren't "A" weighted is
in ZAPCO manuals and literature. We publish only "raw" specs at ZAPCO. If
we don't like the specifications of one of our products we'll make it better,
not try to make the numbers look better.
