One thing has always confused me. I know the impedance of the speakers I have connected to my amp must be the same or greater than that of the amplifier, but on the back of the AIWA it says

'A or B:4~16Ω/SPKR
A+B:8~16Ω/SPKR'

I always assumed that this means that each speaker needs to have at least 16Ω impedance rating? The way it says it just confused me a little. I got the whole thing for free but it didn't come with a users guide or anything. I get the impression it's quite an old model of amp, as I don't seem to be able to find any info on it.

By A and B it means the speakers, the amplifier can connect a par of speakers to output A and B, and then switch between the two or use both.

Also, apologies if this is in the wrong forum >.<

It means your amplifier can handle a load as low as four ohms, but not lower. So you can connect one speaker whose impedance is four ohms or greater, or you can connect two speakers, each of which is eight ohms or greater.

Ahh I seee. That makes more sense; I'd been looking at the final number rather than both! Thanks a lot.
