Actually, a z2200 and a z2300. I guess it wouldn't matter, about the same thing?

I have several questions, I'm sure I'll learn something!

Okay, I have these two Logitech systems. Revisit the idea of using them simultaneously.

- acoustic guitar
- keyboard
- vocal

I have a y-adaptor cable that has two 1/4" female jacks on one end, the other end is 1/4" male. I plug this y-adaptor into the psr2000's Mic jack. Whatever effects I have on my vocal are also on the guitar but it sounds fine to me and has worked with no problems.

So, what about this? On the back of psr2000:

Output (1/4")
R L/L+R

Auxiliary Out (RCA)
(Level Fixed)
R L

BTW, why is Right on the left and left on the right? That doesn't make any sense to me.

Say I want more volume than a single z2200 can deliver. I always go out of Output (Main Out) into the z2200. What about doing that but also going out from Aux Out (Level Fixed) into my second system, the z2300?

"Level Fixed," I assume this means the sound level is maxed out? If so, that's a problem, isn't it? Why do they make it maxed, what is the advantage of that?

If it's maxed out sound coming out of Aux Out, could I go into a mixer (Behringer UB1002) so I can control the sound level?

I note that the psr3000, in addition to RCA Level Fixed Aux Out, also has an Aux Out that is NOT "Level Fixed," so that would make it easier to do what I want?

Any comments about any of this or how to use the two systems when I need more volume?
