Since its founding in 1974, ZAPCO has been committed to the pursuit of sound fidelity. ZAPCO's Our primary goal is to design and manufacture audio products of unmatched quality, provide unparalleled support and service for those products, and conduct the business in a way that improves the quality of life for everyone involved..

There is no substitute for experience; that is a simple fact. Another simple fact is that ZAPCO has been a leader in defining quality standards for the car audio industry for more than forty years. These years of experience have led us to understand the unique challenges of the car audio industry. ZAPCO's relentless pursuit of sonic purity continually results in imaginative designs that utilize the most innovative technologies. The resulting products set the benchmark by which all others in the industry are judged.

The revolutionary Zapco HDSP

The next generation of processing. Zapco began manufacturing in 1978 with the famous PEQ, a 9-band preamp EQ with two-channel control. With balanced inputs, high voltage outputs and military-grade internal components, the PEQ was the first true sound quality EQ for the car. The PEQ was followed a few years later by the Zapco PX. The PX was the first parametric EQ for the car. In the 1990s, the Zapco SX series was released with a parametric equalizer, high voltage outputs, fader and bass-treble balance control. The SX became the new top dog among equalizers on the race track.
In 2004, Zapco was at the forefront of the digital revolution. When others were just talking about digital, Zapco offered the first computer-controlled digital processing network for the car. The DC line consisted of a 6-channel, full-featured DSP processor and a line of car audio amplifiers with fully-featured DSP built in. Zapco's DPN network allowed you to use a single computer screen to switch from amplifier to amplifier to make adjustments. In 2012, Zapco upgraded the DSP to the DSP-Z8 with more processing capabilities and 8 output channels. In 2015, Zapco offered the DSP-Z8III and Z6III in more compact enclosures for those who want to save space and not need to network the amplifiers.
In January 2017, Zapco introduced the DSP-Z8 IV and a whole new level of sonic performance. The DSP-Z8 IV is an affordable DSP with sonic performance superior to many units twice the price and a redesigned user interface that makes setting up a sound system a breeze.
Next, Zapco introduces the ultimate in-car digital processors: the HDSP V-Series. The HDSP offers tuning capabilities never before offered in a car DSP. HD stands for the built-in HD player for high-resolution audio files. The HD processors can be controlled via a direct USB connection to a PC, a touchscreen display, or via the wireless portal with a "smart" device. We have programmed the DSP chips to accommodate any number of different top-of-the-line components, giving audiophiles the ability to easily customize the units to their personal tastes.
