Ppi A7004D Atom 700w Max 4ch Class D Amplifier

Atom amplifiers, which are based on the original Atom and ion platforms, showcase the most exemplary Korean Class-D performance, reliability, and compact design. At first glance, several key improvements are noticeable.

The signal inputs, power/ground, and speaker connections of the Atom amplifiers have been relocated to the leading edge of the chassis, making the installation process easier and more appealing. All pre-amp and crossover options are conveniently positioned on the backside.

The unique installation of Atom amplifiers involves the use of mounting pedestals at each corner. These pedestals elevate the heatsink, enhancing 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.

In terms of power output, the Atom amplifiers deliver: - RMS Power 4Ω: 100W x 4 (14.4V, 1KHz, ≤ 1% THD+N) - RMS Power 2Ω: 175W x 4 (14.4V, 1KHz, ≤ 1% THD+N) - RMS Bridged 4Ω: 350W x 2 (14.4V, 1KHz, ≤ 1% THD+N)

The Atom series amps are designed with sequenced delays to eliminate residual power-up/power-down pops, and they are equipped with differential RCA inputs to isolate 12v audio from ground.

The amplifiers feature a Hybrid Aluminum Alloy Heatsink for optimal heat dissipation, combined with an intricate MOSFET power supply filled with Audiophile Grade IR Transistors. The Military Grade SMT PCB ensures dynamic performance.

The Atom amplifiers incorporate volume low ESR Capacitance Banks to compensate for power supply ripple, and a set of individually regulated Preamp/Crossover components to ensure signal purity.

The amplifiers come equipped with integrated variable 12dB High Pass, Low Pass, and Subsonic Crossovers. They can accept a 200mV-6V Low-Level RCA and High-Level Signal Input, and offer a 12dB Bass Boost adjustment to increase low-octave harmonics.

The dimensions of the Atom amplifiers are 10" LENGTH x 6" WIDTH x 2.25" HEIGHT.
