Car Audio

miniDSP is proud to introduce the latest addition to its line of innovative car audio processors. The all-digital Harmony DSP 8x12 integrated DSP/amplifier features six-channels digital audio input via USB, stereo digital optical input (TOSLINK), Dirac Live® acoustic correction and 12 output channels.

Hardware features dedicated to the vehicle environment include an on-board isolated power supply, remote trigger input/output, and a wired remote with OLED display for dash or console. Flexible output configurations cater to a wide variety of system configurations: each output can be a 40 Wrms power amplifier or a line-level output for driving external amplifiers. In addition, each pair of outputs can be configured in parallel BTL mode for 80 W output into 2 Ω loads.

In addition to Dirac Live, the Harmony DSP 8x12 includes miniDSP’s powerful, easy-to-use audio processing: parametric EQ, compressors, adjustable time delay, crossovers up to 48 dB/octave, and an advanced matrix mixer with rear/center capability. Four complete processing configurations are stored in flash memory for recall with a wired or infrared remote.

What's in the Box?

  • 1 x Harmony 8x12 Car Amplifier
  • 1 x Dirac Live license
  • 2 x Speaker wiring harness
  • 1 x 1m USB cable
  • 1 x UMIK-1 (if option selected in shopping cart)
  • 1 x Control GUI plugin provided automatically under UserDownloads section on purchase

Application notes

This app note describes how to implement an active speaker and Dirac Live room correction in a single box.

miniDSP's multichannel audio processors with Dirac Live room correction can implement advanced multiway active speakers. Any number of "ways" and speakers can be implemented up to the number of output channels:

  • C-DSP 8x12 DL. 12 output channels.

  • Harmony DSP 8x12. The Harmony DSP 8x12 includes power amplification, and can also use external amplification if more power is needed. 12 output channels.
