3-channel stereo

Ceruleance · 04-05-2003, 02:56 PM

So how would I do this:
3 channel stereo, without a stereo preamp and 2 stereo amps (most likely bridging one of them)?
The preamp has two identical sets of outs to work with, Im adverse to just making the center a second right or left channel, would an interconnect that connects to both right and left preamp outs but only terminates into a single RCA on the amp side work sufficiently to 'mix' the channels?

No, don't do it. At all. Ever. Never. Don't. Please, for the love of Jesus Christ don't do it. Don't even think about it.

I understand what you are saying, but you would get very screwy imaging. Everything would come from the center. Stuff coming from exclusively the left channel would seem to be somewhere between the center and left instead of dead off to the left like it should. Why do you want to do this anyway?

If you dont have an AVR with a processor that can mix a center from the L/R I would not bother. For instance my h/k 520 has both dolby and logic 7 which do a 3 channel mix which I occasionally screw around with. IMO it works well with TV programming but for music I much prefer just 2 channel.

This page here shows a few options for setting up multichannel systems with a simple stereo receiver. Interestong read, I would've never thought of some of the crazy wiring schemes.

Diagram 2 would be interesting to play with without the rear settup. It would be fun to flip the polarity of the center to hear what the end result in phasing would be.
Thanks for the link RS that is pretty cool stuff.

Mind Candy at the very minimum.

That is an interesting read, not quite sure I want to bridge my negative terminals just yet, however..

I am considering this 3 channel setup because I might shortly (in the next week) purchase a center channel that kicks the pants off my mains, yet is still tonally matched to them.

Besides, I thought I had made a name for myself already for asking questions that I just wanted to know the answers to.

I'm sure we all would've LOVED that stuff back in like 1970 something. Still pretty cool in 2003.

Ceruleance · 04-05-2003, 05:13 PM

I was definitely craving it, pre-conception style

rs159 · 04-05-2003, 05:20 PM

Yeah, I too was just a retarded little egg back in 1970. No ears at that stage. what a shame

rs159 · 04-05-2003, 05:25 PM

Of course my profile says I was born in Assfahrt, Germany in 1850, but y'all can just ignore that

You could always call up the manufacturer and ask.

Speaking of '70s technology. Actually '67 technology. I have a Dynaco PAT-4 preamp that has dual outs and also allows for a "6dB blend" for a center channel. Although not labeled as such on the front, I believe the owners manual even suggests using one of the inputs for your TV. Not bad for 1967.

I picked mine up for about $50 off E-bay as part of a package deal. You could probably pick one up and daisy chain them. The volume control could be used to mesh across the front.

You might be able to use Y-splits followed by in-line attenuators, but this would probably cost as much.

haha attenuators, I love it:

I'm curious about this statement. I've never used them so I have nothing to go by.

Ceruleance · 04-11-2003, 05:19 AM

basically if you have too much gain(amplification) in your system, it reduces it, so that you can adjust your volume control across a wider range, not just full off full on...
