Description
The ARC Audio PS12-Pro is an eight-input, twelve-output stand-alone digital signal processor designed for high-channel-count active audio systems and advanced factory-audio integration. Twelve independently processed RCA outputs allow separate control of tweeters, midranges, midbass drivers, rear speakers, subwoofers, and additional system zones from one processor.
The Pro-Series architecture uses an Analog Devices ADAU1462 DSP with 32-bit fixed-point processing and AKM Velvet Sound analog conversion. Eight differential analog inputs accept RCA or speaker-level signals from 0.5 to 32 volts, allowing the processor to connect to aftermarket radios or many factory amplifiers. Optical and digital-over-copper inputs provide additional digital-source options.
ARC Audio DNA software provides input summing, full matrix mixing, input and output equalization, crossover control, all-pass filtering, phase and delay adjustment, and four user presets. The PS12-Pro is compatible with iDatalink Maestro AR integration. The current optional wired controller is the ARC Audio LR2; the controller, Maestro modules, digital adapters, and AXP wireless interface are sold separately.
