Carver Mono blocks Silver 7 t and common Ground

These amps are not common ground right? I have them connected to the Polk 1.2's with the negative tired together.I also have the infinity Kappa 9's.when connected to theses should I have the negative tired together,as well... I'm a little confused about the common ground thing. thanks guys

Re: Carver Mono blocks Silver 7 t and common Ground

Typically,,mono's are not common ground--now with the Polks--and mono's-- you can strap the amps together,such as you have done--or in other cases,use or buils a "non-common ground" interface that goes in place of the standard SDA interconnect.I'm not sure,,but I don't think that it matters with the Infinity's,,if you choose to build a non-common ground interface,,the buils can be seen here--

Common ground means both channels share the same ground. Sounds like you're right.

Re: Carver Mono blocks Silver 7 t and common Ground

Most monoblocks drive both the positive and the negative (ground) simultaneously but inverted. Think of a sine wave on one wire and it's inverted cousin on the other. The amplitude of each is the opposite so, if I were observing the positive signal sitting on the ground signal, it would be twice as big. Now, the other monoblock is doing this also, and their grounds are clearly not "common".
It should sound like it isn't there!

Yeah, I knew it was you.

You should really use the AI-1 as strapping the grounds diminishes the sound quality.

Welcome to the Carver forum! I sense some good with this one, Jesse.
In search of accurate reproduction of music. Real sound is my reference and while perfection may not be attainable? If I chase it, I might just catch excellence.

The best way to enjoy digital music reproduction is to never listen to a good analogue reproduction.

The problem was the loose binding post on your one amp. The AI-1 worked perfectly.

They sold within minutes. One of them was the one jbfan77 had.

That's what I was told,,, but I'm happy with my sound now,since I upgraded my Cables to the MIT Shotgun(s).it hard to think,my system would sound any better.Not getting any static now... Hopefully,I will get the opportunity to find another AI - 1 Cable. F1NUT,I didn't know what else to do but send it back. Ted tried to fix it.he put electrical take around it. Do I need to keep the Amps Tied together when playing through the Kappa's... thanks
