The Dirac Series of 24/96 high-resolution audio processors with Dirac Live® are designed to fit into an existing system with minimum disruption, yet with the flexibility to allow for new and more cost-effective system configurations. The DDRC-22A interfaces via analog signals on balanced XLR connectors*. It can be simply inserted into the analog signal path of an existing system, or the on-board volume control used to simplify system configuration. Examples:

  • Between a pre-amp and power amplifier
  • Between a mixing/mastering console and power amplification
  • Between a single analog source and a power amplifier


  • Processor: 32-bit floating-point Analog Devices SHARC DSP
  • ADC/DAC resolution 24-bit, 96kHz
  • Operating sample rate: 96 kHz
  • Signal-to-noise ratio: 114 dB
  • Input impedance: 40 
  • Maximum input level: 2 VRMS or 8 VRMS (jumper selectable)
  • Output Impendance: 560 Ω
  • Maximum output level: 2 VRMS

Application notes on DDRC-22A

The Dirac Series of high-resolution audio processors from miniDSP incorporating Dirac Live® are an advanced hardware/software solution for digital room correction (DRC). In this application note, we'll give a quick run-down on how to use one. We'll assume that you've already obtained your Dirac Live software license and installed the Dirac Live Calibration tool for miniDSP software.

Works extremely well. But I didn' lucky, because one channel stops to sound suddenly, in about one week of use.
I ordered a second unit, and hope it will do the job for more time.

DDRC-22A (Aug 2014)

Although you might need to brush up your French to understand the original version, this review obviously took some great effort to summarize the whole miniDSP Dirac Live experience! Great work from the French team @ Audiophonics and reviewer reviewer Jeff Blackman(Jacko).
PS: French is certainly useful to get your way around south of France so feel free to learn it, but Google translate is doing a good job too! :-)

The DDRC-22A is a serious product that opens up the possibility of adding an active acoustic correction performance in any stereo audio system in good order and without breaking the bank.
