PS8-Pro: Competition-Proven DSP Performance Without Compromise

Designed by legendary car audio engineer Robert Zeff and backed by years of wins in the world’s most demanding sound quality competition formats, the PS8-Pro is ARC Audio’s flagship 8-channel standalone processor—and a true benchmark for high-end system tuning.

Built on ARC Audio’s advanced Pro-Series DSP platform, the PS8-Pro delivers refined signal processing capable of handling up to 96kHz/32-bit resolution, putting absolute precision in your hands—no canned auto-tuning, no compromises. It includes built-in high-resolution optical digital inputs and can also accept digital coaxial inputs via ARC Audio’s optional D.O.C. Adapter, offering flexible connectivity for a variety of source devices. Paired with ARC Audio’s DNA Tuning Software, the PS8-Pro unlocks the full power of the Pro-Series platform, providing one of the most detailed and flexible tuning interfaces available today.

With up to 296 bands of third-octave or fully customizable parametric EQ, ultra-fine adjustable channel delay, dual-routing signal mixers, output trim control, and a deep library of crossover options, the PS8-Pro lets you dial in your system with total accuracy and musicality.

Can’t replace the OEM source? No problem. The PS8-Pro makes OEM integration seamless, with input compatibility from 0.5V to 32Vrms (via RCA or speaker level), intelligent DC/signal-based turn-on, and full iDatalink Maestro AR support for plug-and-play installs in a wide range of factory-amplified vehicles.

Whether you’re building a championship-winning competition system or a finely tuned daily driver, the PS8-Pro delivers unmatched flexibility, control, and sound quality—no compromises, just results.
