Dirac Series

The DDRC-88D is the digital I/O version of the well-known DDRC-88A analog I/O Dirac Live processor. Housed in a compact lightweight chassis, the DDRC-88D provides a full 8 channels of Dirac Live room correction via professional AES/EBU digital inputs and outputs. This unit is also available in SPDIF in/out via COAX cable. 
With 8 channels of Dirac Live processing, the DDRC-88D is ideally suited for professional surround-sound studio, broadcasting and Digital Cinema (DCI) applications. Dirac Live’s renowned room correction capabilities ensure the most accurate and immersive surround experience for mastering and playback. An inexpensive optional software upgrade adds additional processing functions including bass management and active speaker implementation.

The DDRC-88D is configured via USB and a user-friendly software suite that runs on Mac or Windows. Four full preset configurations are stored onboard and can be recalled easily from the front panel or with a remote control. An optional half mount rack adaptor allows easy rack mount installation.


  • Processor: 32-bit floating-point Analog Devices SHARC DSP
  • Input/Ouput resolution: 24 bits
  • Dirac V3 support
  • Matched sample rate clocked to first input channel (e.g. 192kHz in, 192kHz out)
  • Inputs: 4 x Stereo AES-EBU/SPDIF inputs (8 channels)
  • Ouputs: 4 x Stereo AES-EBU/SPDIF outputs (8 channels)
  • dB25 for easy interfacing to DCI processors
  • Optional DDRC-88BM plugin for Bass Management + Dirac Live + Active Speaker processing (Crossover/PEQ/Delay)

What's in the box?

  • Dirac Series Audio Processor — DDRC-88D
  • Dirac Live license embedded inside hardware
  • Universal 5VDC power supply with IEC power cable
  • DB25 to XLR pigtail with 4 x AES-EBU XLR male (outputs), 4 x AES-EBU XLR female (inputs)  OR DB25 to COAX pigtail (4 x SPDIF in, 4 x SPDIF out)
  • USB cables for Dirac Series audio processor and UMIK-1
  • UMIK-1 calibrated measurement microphone
  • Microphone tripod stand (Option)

NOTE: The UMIK-1/2 are measurement microphones approved by Dirac Research. Knowing the major effect a wrong calibration/measurement would have on the final results of Dirac Live tuning, we strongly recommend that you select a UMIK-1/2 microphone together with your platform for a plug&play experience leading to best results. Any issues related to 3rd party microphones such as ASIO/USB audio driver incompatibility/Latency problems or incorrect calibration process will not be under our support structure by our support team. Optional Accessories

  • DDRC-88BM plugin for Bass Management
  • IR Remote
  • 1/2 rack mount adaptor to mount the unit in a standard rack

Exploring the power of the DDRC-88D/BM

Application notes on DDRC-88A

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.

This short app note gives a worked example of the gain structure optimization procedure described in the DDRC-88A User Manual.

In this app note, we will show you how to use multiple subwoofers with the DDRC-88A.
