alright I'm curious to see what others here might think of this situation that arose last night while tuning:

using a pink noise disc I went through and centered every frequency on the h701 and then used the audison pink noise track to test what frequencies were too hot on the RTA. after going through and correcting the hot freqs I went back and made sure all 31 bands were still centered.

At that point I popped in the chesky disc. Tonality was much improved, but a wierd imaging quirk started to happen. Male voices (namely the moderator) would pull hard left, and female voices (track 3 and 5) pulled hard right. I rechecked each freq, and they all appeared centered, but at that point I figured I might have hit the listening fatigue limit, and called it quits for the night. Anyone got a clue if this is anything more than I just wasn't centered between 200 and 1khz?

That's not really uncommon. I've had the same issues before. Find the frequency that's pulling using the RTA, and balance it on real music, or the narator. I've always had to tweak things like that. I suspect it's because of reflections and phase issues that come up when you combine frequencies. The Filtered Pink Noise does not have enough combined frequencies to show those problems. It just helps get you real close. Reflections can make you eq things that didn't need to be touched. I learned that one the hard way.

Then again, you may just have really bad hearing. $\:p$

i did 3 runs with the pink noise last night, and things are pretty much aligned. i have a little bit of pulling, but not much at all. i think my image is still a bit big, but nothing like what you're talking about, scott.

sure it's not hardware issues?

if your crappy zapco gear hasn't overheated then i'm going to go with it being your hearing. $;\)$

and the Winner is: Everyone

I had a few freq's that were way way off, and my hearing was apparantly fatigued beyond belief. I think it's all better now.

The filtered pink noise is just a good reference. Keep that in mind. Many times after using the filtered pink noise I liked the previous setting better.
