Setting up SDA speakers with Yamaha AX-700u integrated amp
I have a new amplifier i want to connect up my SDA speakers to. I recently serviced this Yamaha AX-700u integrated amp and want to test it. Not sure if this a common ground and wanted some advice. I did use a meter and have continuity between both the r/l black(-) speaker terminals to the ground connector on the back. Does this sound like a common ground amp? thanks in advance.
