DDRC-24
DDRC-24, a USB DAC+DSP Digital Room Correction processor powered by Dirac Live in a tiny form factor
miniDSP introduces the DDRC-24, the world’s smallest Dirac Live® hardware processor. Dirac Live®, the world’s premier room correction solution, is now available in an unbelievably compact hardware unit. Powered by a 400 MHz Analog Devices SHARC processor, the DDRC-24 retains the 4-channel output of its sister unit, the miniDSP 2x4 Hd, in order to allow applications like subwoofer integration or even 2-way loudspeakers together with Dirac Live® room correction in a single tiny hardware platform. The matrix mixer and crossover functionality is accessed and programmed with miniDSP’s easy-to-use interface software. An all in one unit with USB DAC + Dirac Live Room Correction + Speaker processing.
I/O capabilities get an upgrade too, with the addition of USB audio streaming up to 192 kHz and a TOSLINK digital input. The miniDSP DDRC-24 will find application in full-sized hifi and home theater systems, on desktops, in cars, in recording studios anywhere a compact, powerful room correction processor is needed.

Application notes on miniDSP 2x4 HD and DDRC-24
The miniDSP DDRC-24 includes not only Dirac Live® but also a full set of crossover functions on its four output channels. One use of this is as a flexible tool for integrating subwoofers into your system along with Dirac Live. This application will show you how to build a 2.1 setup.
This app note demonstrates how to use the DDRC-24 for subwoofer control and correction. While the DDRC-24 is a stereo unit, the flexibility that we build into every miniDSP allows it to easily be adapted for this purpose. How?... read on!
In this application note, we will show you how to design an active 2-way loudspeaker with the miniDSP 2x4 HD. Using the 2x4 HD, you can either create a conventional (Linkwitz-Riley or Butterworth) crossover, or a linear phase crossover.
In this application note, we will show you how to integrate a subwoofer with your existing loudspeakers by using a miniDSP 2x4 HD. You can use an existing preamp, or replace a preamp and a DAC with the miniDSP 2x4 HD. (In the latter case, you will need to program a remote control to adjust volume in the miniDSP 2x4 HD.)
In this application note, we show you how to use Room EQ Wizard (REW) and its integration with miniDSP to equalize your subwoofer.
Delighted. Incredible value for money. Build quality reasonable while the end result in terms of audio quality running the Dirac is superb. A happy customer. Deliberated for far too long given a less than positive review of the DAC on the audiosciencereview site. I shouldnt have concerned myself. DAC alone, to my ear, with my linkwitz orion speakers and a cheap Neo android box as streamer and source via toslink is clean and detailed, while with Dirac the results are excellent.Tom Deacon
I advise any and all Maggie owners to go out and get this unit and add a musical sub, you will be thoroughly impressed. The biggest complaint with the Maggies was not enough low end and subs were hard to integrate. Well no more, the DDRC-24 is the answer. Now you can rock out , listen to a symphony, grove to some jazz and get down to some blues and keep a smile on your face.
Adding the DDRC-24 to my system was the smartest thing I have done in a long time.

The DDRC24 is nice to have for Room Correction in a 2.1 Setup. The key is the Dirac Live Software which is the only thing you will find very well designed and convenient to use. The minidsp DDRC24 take some toll on you for setup as documentation is very weak. In my room there were not many issues so there was a minor improvement in sound quality. Sample rate is only 48 kHz so 96 kHz would be better. Although since 48 KHz should still give you the practical listening range. In my setup where its more analog and listening is via TurnTable and PhonoStage so could not feel the difference. Though the Dirac Live corrected it - but think some quality is lost in this process. Overall - Satisfied with the purchase. With some hiccups was able to setup and room correction did what its supposed to do. If you have a bad room acoustics then this will definitely correct and improve your sound. In my case even though dips and peaks were within 10db the software corrected it to within 5 DB.RDValley
