Don’t let its size fool you—ARC Audio’s PSM-Pro is a full-featured DSP engineered for motorcycles, powersports, and space-constrained vehicle applications. Built around the same ADAU1452 DSP core as some of its other siblings, the PSM-Pro delivers professional-grade tuning and integration in a weather-resistant, ultra-compact housing designed for real-world environments.
With 6 analog inputs and 8 RCA outputs, the PSM-Pro supports full active systems while maintaining compatibility with ARC Audio’s powerful DNA tuning software. It features a digital coaxial input, accepts up to 16V RMS signal, and gives installers access to up to 296 bands of customizable EQ, per-channel delay, phase, and crossover control—just like ARC’s larger processors.
The rugged, fiber-reinforced water-resistant ABS chassis and features pigtail-style wiring for a watertight connection, making it the go-to DSP for motorcycle audio builds, off-road vehicles, and installs where durability and space savings are critical.
Whether you’re outfitting a high-output HD bagger or simply looking to hide a DSP in the tightest space limited modern vehicle, the PSM-Pro delivers flexible tuning and integration—wherever sound takes you.
