Description
The ARC Audio PS-6.8 is a six-input, eight-output stand-alone digital signal processor designed for active audio systems, factory-radio integration, and installations that need flexible analog and digital source options. Eight independently processed RCA outputs allow separate tuning and routing for multi-way front stages, rear speakers, subwoofers, and additional system channels.
Six analog inputs accept low-level or amplified factory signals from 2 to 16 volts RMS. Optical and coaxial digital inputs provide additional source flexibility. The processor uses 24-bit fixed-point architecture with AKM 5358B analog-to-digital and Cirrus Logic CS-4344 digital-to-analog conversion, providing up to 96 kHz processing and 3.5-volt RCA outputs.
ARC Audio DNA software provides signal summing, matrix routing, equalization, crossover control, phase, delay, and four user presets. The PS-6.8 supports iDatalink Maestro AR integration and the optional ARC Audio LR2 controller. The controller, Maestro modules, digital adapters, and vehicle-specific integration hardware are sold separately.
