Zapco ST-4X DSP Amplifier

Zapco's Studio-X amplifier series was designed specifically for today's car audio market. The compact Studio-X chassis allows easy installation in any vehicle, and thanks to the modern, angular black design the amplifiers look great in every installation. The second-generation four-channel amplifier with a DSP processor was engineered to deliver Zapco's unmistakable quality in a compact, elegant black chassis. Thanks to top internal components and innovative design, the Zapco ST-DSP amplifiers boast world-leading sound quality in their price range. For 2019 Zapco offers two amplifiers with integrated DSP processors that let you fine-tune the sound to the last detail.

Key features of the Zapco Studio-X series

The Studio-X series includes fourteen amplifiers in total — ten Class A/B units and four Class D monoblocks. All of these amplifiers use the same bipolar output devices, op-amps, and premium capacitors found in Zapco's higher-end models. Common features of Studio-X amplifiers include variable electronic crossovers (HP/LP/Full Range), variable bass boost, selectable channel-pair gain, high-level speaker inputs, robust terminal blocks, and preamp outputs for connecting an additional amplifier without needing extra RCA cables. Durability and reliability are also strengths. It's not uncommon to see Zapco amplifiers moved from car to car and passed down from generation to generation. Zapco amplifiers made in the 1990s are still bought and sold online by sound-quality enthusiasts around the world. The Studio-X line will be no different. And of course the most important feature shared by all ST-X amplifiers is Zapco's legendary sound quality, developed over more than 40 years of experience.
