DSP with an Integrated Amp?


My gear consist of a Parasound Hint6 integrated driving B&W 606 S2s and a pair of REL t7i's. I have been unsuccessful in integrating my subs using the method REL recommends. My listening room front wall opens on the right into the dining room and the bass is superb... when I'm in the dining room! 

I thought DSP might be the way to go and use Dirac room correction so I contacted miniDSP asking which product I should go with and told them specifically I had an integrated and was wanting to do room correction.. They recommended DDRC24.

I tried numerous configs and was unable to get the program to work so contacted them again. This is the reply I got- 

Unfortunately that won't work in that case as we only support line level. You can't apply DSP to an amplified connection. the DSP needs to be "before" amplification, not after. You'll have to figure out a way to put the processing before... With an all in one amplifier doing 2.1 processing, adding DSP won't be possible I'm afraid..

I reached out to forums and was told I could run source in (Toslink) to the DDRC and run analog out to the integrated analog in. How would/ does this work to do room correction? The only thing it can process is the source correct? I know I'm probably confused and I know Millercarbon will post another link to his system but I could use some help understanding and thus far miniDSP customer service is non existent after purchase.

You would go from laptop to integrated for playing back music.

Dirac on the miniDSP would work, but it would only correct the sub.
So, you've gone round and round with this, not liking the answers.

No, you can't put DSP before your amp with a Hint6, and that's where it has to go to affect the amp.

Your best bet, and it's a very very good one is  a hybrid approach.  Use the built in crossover settings to set a high pass filter to your main speakers and then use your DSP for the sub only.  Here:

  1. Preamp out -> Crossover -> On
  2. Preamp out -> Hz -> 80 Hz or higher
  3. Subwoofer out -> Crossover -> Off

Now, feed your DSP from the sub outs. You'll get full range (due to 3, above) so you'll use the DSP to set the crossover, delay and any EQ there.

Best of luck.
