The C-DSP 8x12 is miniDSP’s next-generation processor for high-end mobile/car audio. The powerful 400 MHz SHARC floating-point processor provides pristine high-resolution audio at internal sample rates up to 192 kHz. With a wealth of inputs and outputs in a compact, rugged enclosure, the C-DSP 8x12 is suitable for installations from simple stereo, through surround systems with subwoofer integration, up to advanced multichannel active systems. New to this upgraded version are the onboard 32bit AKM converters that provide low noise and improved dynamic range to perfect your miniDSP experience.

The driverless USB interface is used to configure miniDSP’s powerful but easy-to-use audio processing: parametric EQ on all inputs and outputs, compressors and adjustable time delay on all outputs, crossovers up to 48 dB/octave, and an advanced matrix mixer. Four complete processing configurations are stored in flash memory for instant recall with a wired or infrared remote.

Hardware features dedicated to the vehicle environment include an on-board isolated power supply, remote trigger input/output, a wired remote for dash or console mounting, and a microSD card slot for offline configuration and firmware updates.

My sound system consists of: Clarion NX-706 NAV Receiver MiniDSP C-DSP 8X12 Processor 1 Powerbass XL-4165M 4 channel amp 2 Powerbass XMA-4250IR 4 channel amps 4 Powerbass XMA-2000D monoblock amps 8 Powerbass 4XL-2H 2” Horn Tweeters 8 Powerbass XPRO-8 8” mid ranges 8 Powerbass 3XL-1501D 15” subwoofers 2 Powerbass XL-POD6LR 6.5” wakeboard speakers 2 Powerbass 2XL-3M 3” silk midrange drivers 2 Powerbass S-1S 1” silk dome tweeters This whole system is only possible to manage with the C-DSP 8X12. I run fiber optic cable directly from my radio receiver into the processor for the cleaners. Signal. And then to my amplifiers I have 12 channels of output at 6 V for clean signal. I also have a wired controller which I have set up with for precepts. Two of them for car show related positions one of them for sound quality and the last one for my own personal listening. The knob controller is set to run my subwoofer channel. There are a lot of processors out there but none of them with the features that this one has. @sq4me2 on instagram to see my ride.

You just can't beat this DSP's price/performance ratio! Easy to use, almost automatic eq'ing when used with a MiniDSP UMIK-1 and REW. The customer service is spectacular as well.
