ASP Series

In 1978 Zapco introduced the world to audiophile signal processing with the iconic Zapco PEQ 18 band equalizer. It was the first high output processor for the car. With high grade “mil-spec” slide pots and internal components, the SEQ showed the industry what in-car sound processing should sound like. The SEQ was followed by a series of audiophile quality processors including the first parametric car EQ, innovative electronic crossovers, a 30 band mono EQ, an advanced noise gate, and even an outboard D/A converter that surpassed most home D/A converters.

Now, when most head units and amps have processing built in, Zapco continue to offer audiophile quality outboard processing.

For many people“OK” sound is just fine as long as it’s quick, and easy, but Zapco makes processors for those who want something better.

We make processors for those who think that the live musical experience is worth the extra effort. We make processors for those who think that the sound is what matters most. If you want to sit in your car and feel like you are right there, in the audience, at the concert hall...

Zapco makes processors for you.
