My audio/video receiver in my home theater apparently has two pre-out on top of all the bare speaker wire connections. There is a sub-woofer pre-out which I know what I would use it with but there is also a center channel pre-out. Now, I already have a center channel speaker hooked up to the system but does that center pre-out mean I can have 2 center channels running at the same time? Please help me understand what the deal is with the center channel pre-out since my manual has given me no real help except to say I can use it for my tv's speakers.

if its a pre-out, its probably a low voltage signal to go to another amp. i dont know why it would just be for the center channel, unless maybe its for a rear center channel.

I had a Sony STR-D2020 that had a Center Pre-Out but no Center Powered Out. WAY back when I was selling audio equipment in college, a Sony rep (yes, they really do exist!) had an interesting answer.
The purpose of this output was to direct dialogue and positional audio to the TV's speakers. The reason was esoteric, as many home entertainment setups were not friendly to a separate center speaker. Plus, there was this misconception that if the sound didn't come from the TV, your eyes would tend to draw themselves away from the screen and up (or down) to the center speakers.
Pre-outs are normally always-active, so if you run RCA cable(s) from the output(s) on the receiver to the TV, they should run in conjunction with your powered center speaker jacks. You'd have, for lack of a better description, a quadrophonic center channel. -
That's really interesting. Now that I am sure what it's purpose is (to use your tv as the center channel) I will stick with my current center speaker anyway. My system is already extremely powerful but I will probably opt for a powered sub for my sub pre-out....then the bass is here will be totally redicoulous!
Thanks!
