Cartridge Alignment HELP


I am trying to align my new Ortofon 2M Blue cartridge on my Audio Technica AT-PL120 turntable, but I don't know how. I understand that I can use the protractors posted on Vinyl Engine, but I don't know how to use them. I can't find any videos or specific instructions; the closest I can find just say to "align it."

But how? How EXACTLY do I align my cartridge?

G'day mate, this article I've written on the general subject may hopefully assist. Regards, Fap. http://www.mds975.co.uk/Content/vinyl07.html
Thanks a lot... but I still don't see how a two point protractor (like the one you linked me to) could work. I mean, do you have to move the protractor/platter after aligning it with the first point so that it can be parallel with the lines around the second point?

This one seems to make more sense, what do you think? http://www.enjoythemusic.com/freestuff.htm

I don't understand why I'm so confused about this issue, everything I've read makes it sound like it's so easy... Agh... What am I missing.

Help from anyone would be much appreciated. Believe me, I appreciate it...
Hi, I feel your frustration. I got into vinyl about six months ago and it has taken about that long to learn how to set up a cartridge correctly (overhang, azimuth, vta, sra, vtf etc). If set up correctly it can sound very good if it not it can sound mediocre to bad. Here are a few of my observations. You have to enjoy the process because it is a process and it takes some time. Definitely not plug and play like CD. There is a lot of good information on agon and the internet it takes awhile to find and digest but it is there. Here is a good starting place http://www.soundfountain.com/amb/ttadjust.html. Good luck
