USD0.00 InStock Customer Support
Dirac Series

Introducing the miniDSP Dirac Series, powered by Dirac Live®, the world's premier room correction solution. We are delighted to offer you this software and hardware combination, the fruit of many years of experience in sound system tuning and extensive research and development. The DDRC-88A is the big brother of the stereo DDRC platform introduced early 2014. Based on our proven 8x8 DSP board and miniSHARC powerful module, the DDRC-88A combines two successful & proven platforms into a cost effective one rack unit processor. An infrared remote learning feature and the front panel rotary encoder allow for control of the DDRC-88A processor without any need for a connected PC, once the processor is configured and filters loaded.

Finally, the DDRC-88A is an upgradable platform thanks to the power of the DDRC-88BM plugin. The software plug-in extends the capabilities of the DDRC-88A multichannel Dirac Live® processor. 100% compatible with all DDRC-88A units in the field, the DDRC-88BM adds comprehensive fine-grained bass management and crossover capabilities. The input signals are low-pass filtered and summed to generate the subwoofer signal; a matrix mixer routes or mixes these channels for the Dirac Live® algorithm, which in turn has its outputs routed or mixed to the output channels, where additional high/low pass and parametric filtering takes place. In addition to improved bass management for conventional home theater signal paths, the DDRC-88BM allows innovative solutions like multi-subwoofer control and combined DRC/active loudspeaker setups.

STOCK UPDATE (Jan 2023): The DDRC-88A is unfortunately out of stock due to shortage on the main MCU. No immediate timeline for restocking unfortunately.. Stay tuned.

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.

In this app note, we will show you how to use the DDRC-88A to apply Dirac Live® room correction in multiple rooms. In this app note we will assume that there are four stereo zones to be set up.

After read a lot! i was c, DDRC-88A did the magic trick. I have an HD800 headphones and i like the neutral and well balanced sound, all is in place; the sound with the DIRAC is more neutral and well balanced like my headphones, something very difficult to reach because the acoustics. If you have a great equipment do you a favour and buy a Dirac minidsp rig, you will be so satisfied and you will have the peace of mind that you're listen the best from your equipment. Israel Ramírez

DDRC-88A with DiracLive is amazing. My speakers are transformed. I heard about the product via word of mouth from a highly respected film sound designer and I am glad I took the leap. It is indescribable the difference it has made. Things sound perfect through my system now. And the tech support is amazing. I mistakenly ordered a kit for the 8x10HD and when I realised all I had to do was post it back and it was returned as a DiracLive system as I had originally wanted. Communication was great and the product is amazing. Mixing and mastering has just been made a whole lot better for me and I can’t wait to put the next job through the new system.

DDRC-88A review (Aug 2015) - AVSForum

When I listen to the system with Dirac Live and then switch to MCACC Pro, I'm reminded of why my first encounter with Dirac was so memorable. It elevates the whole system, much more so than any other $1000 investment I can think of—as long as you've already got some good gear. The effect of a room is an overwhelming element in any system. The degree to which Dirac Live takes the room out of the equation sets it apart from any room-correction system I've heard in the past. I consider it a must-have.

miniDSP DDRC-88BM review (Oct 2016)

When Wayne Myers takes on the task of reviewing a product, you know he will take the time to dig deep every single features of the product! Here again, we're very fortunate to see an inside out review of the benefits of the DDRC-88A + Bass management plugin. Check it out!

Once in awhile you come across a piece of audio gear that acts as nothing short of a Value Multiplier for your system. The miniDSP DDRC-88A with Dirac Live plus BM firmware and plugin for Bass Management is a Value Multiplier if I ever heard one, Approach it with patience, Get to know its capabilities. Adopt it into your audio gear family with care, and it will reward you with refined soundstage, imaging, impact, clarity, and detail that might just kick your system’s asset level right into the extreme envy category. Count on the perceived value to be multiplied at least several times. Don’t fall in love, your 88BM is just a box of electronics. Do prepare to be spoiled, though, that much is unavoidable. And don’t feel guilty about the envy of your audio buddies, send them a link to the miniDSP site, there are plenty of 88BMs to go around''

miniDSP DDRC-88A review (Feb 2017)

When Mike @ ProTools Expert contacted miniDSP and Dirac Live to learn more of our room correction series for a studio application, we were very excited at this opportunity to get the product tested inside out on his system. The end result is an exciting review with lots of great feedback. Make sure to check it out here.


The price point is just right, especially when you compare its features and price with Sonarworks and Trinnov Audio. $999 for an 8 channel unit that can handle up to 7.1 monitoring is impressive, and if you need bass management then that is just an extra $99. For me it has the benefits of Trinnov in being a separate piece of hardware that sits between my interface and my monitors and the price closer to Sonarworks.

The 4 presets, which you can select using the front panel controls, could give you a range of different profiles, maybe one for the mix position, another when you have two people sharing the mix position, maybe a 3rd for the client sofa.

They write my kind of manual, it is clear and easy to follow, has lots of screenshots, as well as background explanation to help understand what is going on, the works. Then there is also loads of additional information on their web site too. Then there was their very helpful and knowledgeable tech support team too that responded very promptly with considered answers.

But ultimately, it comes gone to the sound and even though I have a very good monitoring system, the review unit won't be going back to Hong Kong. I will be buying it and sending them the money instead. Enough said.
