Default correct # of poles source selector?

Hi all!

I continuesly see 2 pole source switches...but are not 4 poles needed? One needs also to switch grounds to avoid ground loops, correct?

With 2 poles one needs to connect all input grounds to the ground pad of the amp which can't be good ground loop wise.

Am I correct or is this complete banana?

Thanks! Have fun! Hannes

Sorry for my banana post!

Of course input grounds are all connected together - otherwise one would get dc offsets which would make switching funny. So 2 poles for stereo sufficient.

Have fun! Hannes

Actually, your first post was correct. There was detailed discussion of this topic recently on the forum. Search first...
