Overview

Ultra-compact D-Class 4ch Amplifier with one-side terminals for easy installation, High-Level Signal Input and hybrid aluminium alloy heatsink for heat optimum dissipation. With 800W max power, an individually regulated preamp/crossover power supply ensures signal purity.

Atom Series

ATOM amplifiers adopt the most exemplary Korean Class-D performance, reliability, and footprint of the original ATOM and iOn platforms. At first glance, you'll notice several key improvements. ATOM's signal inputs, power/ground, and speaker connections are relocated to the chassis's leading edge for an easier, more appealing install. All pre-amp & crossover options are conveniently located on the backside. You might not notice additions to the circuit board, including improved power supply & output stage components & monoblock bridging capability.

The installation of ATOM amplifiers is unique, using mounting pedestals at each corner. The pedestals elevate the heatsink, improving airflow around and underneath the chassis. Additionally, rubber grommets under and inside each pedestal electrically isolate the amplifier chassis from the vehicle chassis, reducing the potential for ground loop noise.

Precision Power

Precision Power was initially created with Sound Quality Audio enthusiasts in mind. Today's Precision Power's mission is to lift the brand's image beyond consumers' expectations. Our engineering bravery will set new standards for Car Audio & Precision Power.

Competitive price points that reflect today's market without degrading performance are possible only by the most recent technologies such as SMT production, newer advanced amplifier board topology, and premium grade output components that provide best-in-class sound quality at reasonable prices.
