Pioneer sx-750 help!

[Zach Nelson]

I recently fumble upon a pair of Polk SDA CRS+. I need to get the IC cable. My question is about common ground. Does my pioneer sx-750 have common ground? I also have a "big box" Yamaha receiver from 2005 era. Natural Sound AVR. Will these work with damaging something?

If you are referring to 120v AC to wall outlet 2 wire plug. All amps manufactured for consumer use, by law, are internally grounded.

I've just read so many things that say make sure your amp/receiver has common ground with these SDA speakers and don't know what it's talking about

Yes, it is common ground.

Yes, it is common ground.

Both?

Both?

The Pioneer. The AVR, what model #? Or you could just connect grounds with a multimeter and check for continuity.

Your Front L/R A speakers are common ground, and your B speakers are on a separate common ground. Each other channel has its own ground.
