DDRC-88A8xIN, 8xOUT Dirac Live® correction DSP with Balanced & unbalanced Input & output. Boxed in sturdy 1 RU metal enclosure.
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.

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.
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.

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''Wayne Myers @ HomeTheaterShack
