Highlights And Technical Specifications - zapco Z-150.2 AP Owner's Manual

We doubled the output drivers, and increased the operating voltage of the matched final
output devices. To get heat off the output devices faster, and increase efficiency, we used
a new insulator material developed for aerospace. At the differential input stage, we
used 0.1% resistors... not 1% but 0.1%... to assure the lowest possible floor. We developed
our own patented, multi ground RCA connectors with extra heavy gold plating for
perfect signal transfer. We even improved the low noise gain pots had added detents to
make watching levels a breeze.
And what the heck! To top it all off, we gave it a new look, with a matt black finish and a
solid copper plate with the logo and serial number engraved right in for posterity.
The Result: The ultimate SQ amplifier designed by listening with ears and much as by
measuring. So we get the possible smoothest, purest overall sound quality and, at the
same time, a signal to noise ratio of over 110dB, so you get all that pure sound quality in
even the quietest of musical passages.
