Description
The ARC Audio PSM-PRO is a compact six-input, eight-output stand-alone digital signal processor designed for motorcycles, powersports vehicles, factory-audio upgrades, and other installations where available space is limited. Its 3.75 × 3.0-inch footprint provides eight independently processed RCA outputs without requiring a full-size processor chassis.
Six analog inputs accept low-level or amplified source signals from 2 to 16 volts RMS. A digital coaxial input provides an additional source option. The processor uses 24-bit fixed-point DSP architecture with AKM 5358B analog-to-digital and Cirrus Logic CS-4344 digital-to-analog conversion, delivering up to 96 kHz processing and 3.5-volt RCA output capability.
ARC Audio DNA software provides input summing, matrix routing, equalization, crossover control, phase, delay, and four user presets. The PSM-PRO supports iDatalink Maestro AR integration and can use the optional ARC Audio LR2 controller. Integration modules, controller, cables beyond those supplied with the selected product, and vehicle-specific harnesses are sold separately.
