Well, you can use one compressor for 2 voices, but you'll then have to record those 2 voices on one track. I don't think that's what you are looking to do.
OK- the other thread has a LOT of good info in it, but I can see where it might be a bit confusing for a rookie. Let's see if I can clear up a few of what seem to be your concerns:
1) The Alesis compressors work, but not nearly as well as the other units that have been recommended. If you're looking to get the best sound out of your $350 budget the Alesis compressors are not the way to do.
2) For your price range, you will NOT find a better deal than 2 RNC's for your 2 vocal tracks. Period. In this price range the RNC exists in a class all its own- that's why you keep getting folks recommending it.
3) A vocal processor is a single unit that has a bunch of things that typically get used on vocal tracks: compression, expansion, EQ, reverbs, delays. Make sure you know what it is, what it does, and why you need it because they are all different. They also all tend to be mono (only useful for one voice at a time) even if they have stereo outputs.
4) A good compression unit (like the RNC or the dbx units mentioned in the other thread) will typically give you better sounding compression and more control than the compression section of a vocal processor.
5) Your Lexicon will probably do all the things a vocal processor would do, in combination with a decent compressor.
6) You are recording to your computer, right? What program are you using? Why not use the vocal effects in the program? Or are you mixing with the Mackie and recording live (Micing up the whole band and mixing it to a stereo track on the PC)?
Anyway, I hope that was helpful.
