Zapco Digital
Who has the number one name in state of the art audio equipment?
Zapco!
But, when most people think of Zapco, they picture compact, powerful,
great sounding amplifiers. While this picture is true enough, it misses one
big piece of the Zapco legend.
Signal Processing!
Zapco virtually created the concept of high sound quality processing in
the late 70’s when we created the PEQ. This was a high voltage preamp/EQ
with and audiophile input stage and 9 bands of equalization for each
channel. It brought a whole new level of performance to car sound. In the
90’s the name was changed to SEQ and the unit is still in production today.
In the 80’s we took processing to another new level with the PX. This
was the first audiophile quality preamp EQ with a multi-order crossover. In
addition, all four EQ bands were parametric, so now you could customize
the EQ parameters to you car. The result: By the late 80’s even non-Zapco
dealers had to have a source of PX’s for all their competition cars.
The next leap was in the 90’s, when Zapco introduced the SX, (later to
become the SX-SL). This unit expanded the Parametric EQ to 5 bands,
added dual high pass and three way band pass crossovers, added variable
crossover slopes, bass-to-highs balance, and SymbiLink™ Balanced inputs.
Also in the 80’s / 90’s we added the DA II, EQ30, SP-7, and two
electronic crossovers. So by the end of the 90’s many audio competitors
(especially the ones winning) were running two or more Zapco processors.
OK! Cool as that is, it is still just history!
What is Zapco doing for today’s Car Audio fanatic?
We’re Going Digital! Zapco began using on-board digital processing
and control in 1999 as we developed the famous 9.0XD, Class D amplifier.
Now, in 2005 Zapco again takes a concept to an entirely new level of
performance and functionality.
