It's Gone

Gotta love those big meters!!!

Unit works great, was powering Polk SDA for last 10 years

Krieckie, this is not a common ground amplifier if memory serves. If this is the case then he never enjoyed what the SDA's have to offer.

Onkyo made some power amps with the biggest meters I've ever seen.. lol they just looked ridiculous. I'll see if I can find a picture.

You meant like these.

It can be used as a common ground Amplifier it just requires that you connect the speakers to the back of the Amp so that the neutral (could be hot I’m doing this from memory) wires share a single post on the back of the Amp there’s actually a diagram printed on the back of the Amp between the posts showing how to do this and its covered in detail on pages 6 and 7 of the user’s manual.

If you do that, then one channel will be out of phase with the other.

Yes this is covered by the manual.

From the M500t Owner’s Manual Pages 6, 7

A common ground switching system may be used you will have to connect the common ground wire to the black terminal marked “chassis”, and the two outside terminals (one black, and one red) become the “hot” signal leads and may then be routed through the switching system of your choice. (The red terminal marked “chassis” remains unused.) At this point, there is no electrical conflict in terms of ground or signal leads; however, in order to preserve phase integrity, the wires that connect to each left speaker in the system must be reversed 180.

The last line addresses the phase integrity issue that you mentioned sorry if I wasn’t specific enough in my last post.

This all getting so complicated, I may just order a Bose radio and be done with it all. Actually, have no decent radio signals back here in the woods, but think some of those had a built in CD player.

Get your self one of these OO. You'll get stations in the backwoods ! This is my bedside radio and alarm clock. I love it.

But, I'm confused how this works with Polk SDAs (which was how this all got started). How do you do the switcheroo at the Polks and still use the SDA capability (you're putting the hot on the ground there).

Ok,

I was wanting to use the m500t on my SDAs for the time being.

I feel this was left unfinished so I need some clarity.

If not, then I'm thinking about using the amp in mono to run the sub for the time being. I'll look at the diagram on the back but someone want to explain it to me anyways.

Just don't want to screw anything up.

Brock- if you do not use the "SDA" cable- they are just normal speakers, so you can use them in that manner safely.

Brock, you need what Jerry has. I think it's called the AI-1 Dreadnaught or something like that. It is specifically built to let you play any amp that is not a common ground amplifier on the SDA's with no loss of the sound dimensional array. He's not using his right now and I know he wants to get rid of it because he asked me if I wanted it at CF. Just give him a jingle or a PM.
