Hello, I have an integrated amp with a impedance switch on the back and I have no Idea what to switch it to. I bought the unit used(no manual) and can't find any documentation on the web for it. my speakers are 8 ohms and one side of the switch has written: main and remote and has a setting for 8 and below that 16,the other side of the switch has written: main or remote and has a setting for 4-6 and below that 8-16. I've only got one set of speakers hooked up and no plans to add more. So I guessed I should have it on the bottom setting for 8-16 but I'm really not sure. if anyone has any idea and could help I would really appreciate it. Thanks!!
