| Re: Time aligning with REQ?
TerryJ -- here's what I worked out.
I used the DEQX's room measurement functionality to measure the delay time for each channel. It's fairly easy to see on the impulse response graph and on the step response graph in the viewer.
Based on that, it was obvious that my left was .1ms quicker than my right.
It was also obvious, although less so, that there was a 2ms to 4ms difference between the subs and the mains. Based on that I created four profiles, each of which differed b 1ms in the delay on the fronts relative to the sub. I then tested each of those using REQ, and observed the frequency response around the crossover point. There was a 15db swing between 0ms and 4ms, with 4 being flattest +/- 30hz either side of a 100hz 60db/octave crossover.
BruceK -- my Meridian offers that much correction. I can get 20' out of the distance settings, and the rest out of the ms settings for each individual surround processing option. The DSP filter in the DEQX is 24.8ms long. The A/D and D/A (it's inserted in between my processor and my amp) adds 6.9ms to that.
My issue now is that there's a bit, just noticeable, of lip sync delay that I've got to figure out how to get rid of. When listening to music it's not an issue, so now I'm off to find some sort of video processing delay device.
