Zapco has a reputation for unrivaled sound reproduction quality and high reliability. It is dedication to sonic purity and passion for performance that built Zapco's reputation. No newly introduced Zapco amplifier has ever threatened the company's standing as a maker of premium amplifiers and processors. But not everyone needs an audiophile amplifier for competitions or personal use. The question arose whether Zapco could use 40 years of audio experience to develop an amplifier for everyday use — an amp everyone can afford that still remains true to Zapco's legacy in terms of sound and reliability. The answer is definitely yes! With the new ST-B (Studio-B) amplifiers, Zapco brings high-quality sound that is now affordable for everyone.

  • Stable down to 2 Ω, bridged to 4 Ω.
  • MOSFET power supply.

Important features of the Zapco Studio-B amplifiers

While sonic quality is always Zapco’s top priority, the Studio series amplifiers also include other factors that make them suitable for everyday use. The aluminum chassis is more compact and lighter so this model range fits more easily into today's smaller cars or tight spaces. The amplifiers offer the versatility and rich feature set you expect from higher model ranges. Crossovers are included, and the monoblock also features a subsonic filter or phase invert, plus RCA outputs for easy daisy-chaining between amplifiers. The ST-B amplifiers are not intended for competition; they are designed for daily use in your car. So play your favorite music, turn up the volume and you’ll see that the dedication to sonic purity is definitely a good thing.
