For those of you who have Time Alignment capable h/u's. A gift:

I hate trying to figure out what I need to set the values to, so I made an excel sheet and thought I'd share. Some of you may have something like this already, but if you don't this might help you save some time.

The numbers in the sheet are pretty precise. Alpine's manual says you can do in .10 ms increments, but the values you get go out to the 5th decimal place (you can fix this in Excel if you want) so just round up or down.

The numbers in the file are for my car. If you need helping figuring it out, let me know, but I think it's pretty self-explanatory.

This uses inches converted to meters. Or below that I have it setup to be based on inches alone.

It's an Excel file. Had to .zip it since the forum doesn't allow for Excel attachments.

Enjoy.

I knew I shoulda put the final version up instead of that picture.

I checked my sheet using Alpine's example in the processor manual to check my results and got the same numbers. //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

Don't go by the numbers. Just close your eyes and center the music. That works well. My p860mp says my passenger mid is 70 inches away but it's only 50 or so.

I do that, but I like using numbers to get me a ballpark figure. Same way I set my gains. I use a DMM to get me within reason of what I need to be doing, then do the rest by ear. There's no right or wrong way. It's just preference.

All I was trying to do was throw that out there to help those who might want it. I'm not looking for a cookie. Hell, I was doing it for myself, and thought I might as well share it with the forum (and other forums as well). If you don't want to use it, then don't. //content.invisioncic.com/y282845/emoticons/fro.gif.c695f1f814b01c4ad99fe7f8cccadd29.gif

I tried the auto time alignment on my 880 and hated it. Ill mess with it futher in the future, but am I the only one who thinks time alignment doesnt sound right? Im just getting used to no rear fill (I have rears, but set thm so I cant hear them up front).

Time alignment made a significant difference in my last install, then I had a slight mishap with the HU...

It improves the sound tremendously IMO. Set it with a vocal heavy track. Live music works well. Get Alice in Chains MTV Unplugged. Rooster is a good one to use. Close your eyes it helps. T/A is one of my favorite features.

I agree. It makes quite a difference. I havn't got it down to a science by no means, but on my X-990, I just played with it until it sounded good. Certainly, I could here a difference. It a nice tool to have in your tool bag of tweeking.

I haven't heard good things about the auto TA/EQ. Grab a tape measure and do it manually, you won't be disappointed. I did this with my 880 and the imaging is great.
