Zapco ST-750D SQ III Amplifier
The Studio-X amplifier series from Zapco was specifically designed for today's car audio market. The compact Studio-X chassis allows easy installation in any car, and its modern angular design ensures that your audio system looks as great as it sounds. Speaking of sound... This is a Zapco amplifier, where sound quality is always the top priority. However, durability and reliability are also key features. It's not uncommon to see Zapco amplifiers being passed from car to car and from generation to generation. Zapco amplifiers made in the 90s are still being traded and purchased online by sound quality enthusiasts worldwide. The Studio-X series amplifiers are no different and are built to last for decades.
Zapco Studio-X Compact Amplifiers
In 2022, Zapco introduced revamped class AB and D amplifiers in their third generation. The amplifier chassis is completely new, replacing black with brushed aluminum, and several internal component modifications have been made to further enhance sound quality. All amplifiers use bipolar output devices for the smoothest sound. Shared features of the ST-X amplifiers include variable electronic crossovers HP/LP/Full Range, variable bass boost, variable gain by channel pair, speaker level input, high-durability terminals with positive locking, and preamp outputs for daisy-chaining to another amplifier in your system without adding extra RCA cables. The most important feature shared by all ST-X amplifiers is the legendary Zapco sound quality, developed with over 40 years of experience. This also applies to the new Studio-X Compact series, which offers significantly smaller dimensions, high efficiency, and quality sound inspired by its analog counterparts. Sound quality is what has always defined the Zapco brand, and their engineers have worked hard to ensure that their digital amplifiers do not fall behind the legendary Zapco sound.
