C-DSP 8x12
Premium Digital Audio Processor for Mobile/Car audio installations, 32bit floating point SHARC ADSP21489 @ 400MHz, 8x12 I/O, Remote for Preset/Master & Sub volume control
  • 400MHz 32bit Sharc Floating point processor, Up to 192kHz processing
  • Digital and analog inputs (Low/High levels), 12 analog outputs
  • Flexible DSP processing blocks, Rear Fill processing (L-R, L+R..) thanks to internal matrix
  • Windows/Mac compatible GUIRemote control or preset/master & sub volume control
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.

The C-DSP 8x12 features an onboard isolated power supply, stereo digital inputs (x2), 6 analog inputs, 12 analog outputs, and miniDSP’s powerful but easy-to-use audio processing:

• Butterworth and Linkwitz-Riley crossovers up to 48 dB/octave
• Ten bands of parametric EQ (peaking/high shelf/low shelf/all pass) on every input and output channel
• Advanced biquad programming for an unlimited range of filters and crossover types
• An advanced matrix mixer for routing and mixing of any input to any output, with individual gain control and inversion at every mixing cross-point
• Compression, time delay and level adjustment on every output channel

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.

Customer Review

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. 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. Velozity

First of all, let me comment that the unit is perfectly quiet. I have read some posts on the miniDSP forum about a hiss problem, so I was a little apprehensive to go this route. But fortunately, mine has no noise issues at all.

My application: 2014 Honda Accord Head Unit -> AudioControl Matrix Plus -> miniDSP CDSP -> Amp -> Speakers.

I'm having so much fun with this miniDSP... it truly is a tweaker's paradise. I got this hoping that I could control my bass issues. I tried half a dozen different subs with every crossover/eq/phasing adjustments I could think of, but nothing worked. The bass was either non-existent, one-note or boomy. After my first sweep with REW using the UMIK-1 and processing the REW EQ coefficients, the bass issues were no more. Now the bass is tight and smooth through the entire range. I think a big part of the problem came down to controlling the crossovers. The active crossover features in the miniDSP are worth their weight in gold. Now I have actively crossed over the subs, woofers, tweeters - removing all passive crossovers (with the exception of one cap (-6dB @1000k) to protect the tweeters in case I accidentally bypass the DSP crossover). The improvements are simply amazing. It all seemed a little overwhelming at first, and I am a complete noob to this, but now it's all starting to make sense and I'm having a lot of fun with the process. Honestly, I've just scratched the surface on what this thing is capable of doing.
