Digital crossovers in a home theater setup?
« on: 6 Jan 2008, 01:29 am »
Are any of you with active speakers that utilize a digital crossover (DCX2496, DEQ/X, etc.), using this setup in a HT or mixed 2-channel/HT environment?  If so, how are you configuring your system for the HT side of the equation?

I'm asking because it seems to me that if you want to use your active speakers in an HT setup, you are going to be forced to have extra DA and AD stages that you can avoid in the 2 channel setup.... no digital crossover that I know of can decode todays HT audio formats, and no pre-pro outputs decoded PCM or other digital audio that a digital crossover can understand due to DRM restrictions.  Thus, when you want to run your active speakers in an HT environment, you'd have to take the analog output from your pre-pro, convert it back to digital before or inside your digital crossover, have the digital crossover split the signal as needed for the individual speaker drivers and perform any room/speaker correction, and then convert back to analog to drive the amps.

Is this correct?  Is there another option, or set of components out there that can avoid this?  I'm not as concerned about the audio quality for HT as I am for 2 channel listening, but I'd hate to give it up if there was an alternative.

Thanks!

From my understanding your conclusions are correct.  You'd have to do this with DEQ or DEQX or TACT.  TACT has/had the Mch preamp that did XO/EQ and surround decoding but it was big bucks.  The only other way I know to do it without intermediate steps is a HTPC or PC/pro-audio setup.
