Since my 500-C has 2 speaker selections, I thought I could bi-amp or bi-wire my AR-2AX speakers which have the ability to separate the woofer driver from the mid-range and tweeter drivers. I was curious if there would be any improvement to the sound. I connected the speaker1 outputs to the woofer driver lugs and the speaker2 outputs to the mid-range and tweeter driver lugs. Since the AR-2AX only has 3 lugs on the speaker, one of the common leads from the Fisher is not connected to anything.
It works, but I'm concerned about the risk. I've been told that the 500-C doesn't have a common ground and because of that it is possible for something bad to happen either to the amp or to the speakers. I'm unknowledgeable about it though. Can anyone shed any light on if it's OK ? The sound seems pretty good, but at one point while I was listening, I thought I heard the woofer driver cut out so I turned the receiver off immediately. Later testing proved everything is OK. I don't believe it's genuine bi-amp'ing because the 500-C is not really 2 separate amps.
On another topic, I'm thinking about adding a fuse to the speaker out leads from the Fisher just in case a power spike were to occur. I've figured out the correct amperage. I believe I would install the fuse on each positive lead from the Fisher to each speaker. Does that sound like the correct approach?
