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.

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.

I'll be brief. In a word, this processor is EVERYTHING. I am very happy with it, and totally satisfied. I owned a C-DSP 6x8 also and this 8x12 is certainly an upgrade worth the extra cost. This processor can compete with and probably surpass processors costing over $1000 from other companies. The additi. You can customize the remote in/out time delay right from the plug-in. All of this plus 10 PEQ bands per input and output, and a full 192kHz processing path. This is really the best processor on the market if you don't need wi-fi, bluetooth, and a HiRes audio player. The only thing missing is LED or numerical indication of volume level on the remote. Hopefully MiniDSP will release a new remote with this feature one day. This is an outstanding processor that easily earns 5 stars.
