New to me Mitsubishi Stack

[mikejennens]

I picked up a Mitsubishi DA-A30, DA-P30, and DA-F30 tonight for $100. The DC offset needed adjusted and a fuse that controls the indicator lights needs replaced. Once I get the fuse replaced, I'll hook it up and see how it sounds. It's pretty clean and from a non-smoking home. Once it gets lit up, I believe it will be a pretty impressive set-up. I've never owned any Mitsubishi stereo gear, so I'm anxious to see how it sounds. The amp looks pretty beefy. I believe it is a dual mono configuration.
Can anyone explain the difference between the AC and DC inputs on the power amp?
Thanks,
Mike

Can anyone explain the difference between the AC and DC inputs on the power amp?

Presumably AC and DC coupled, respectively. Running DC coupled was hot back in 1980 or so. (Meanwhile most people have recognized that it gives little benefit over thoughtfully-executed AC coupling but may be good for some nasty surprises.)
