I just picked up a nice pair of Polk SDA 2B speakers and was just about to hook them up to my vintage Yamaha CR 2020 receiver when I noticed on the back of the speakers it says not to connect the speakers to a non-common ground amp.
This may be a silly question but I definitely want to err on the side of caution before hooking it up -
Is the Yamaha CR 2020 a common ground amp?
I assume it is but really do not know (what is a non-common ground amp?) and want to make sure before playing the SDA 2Bs through my Yamaha CR 2020.
Thansk.

Hello,
In looking at the receiver's schematic the negative speaker terminals are connected together, so you're fine with a common ground speaker connection.
Enjoy, Ken -
Thank you.
