I think the places to investigate for hiss are the mic and the mixer.
1. Mixer. It must provide more gain for mic inputs than for aux and
other line-level inputs. For that reason, we're most likely to
notice mixer hiss when using a microphone or a magnetic phono
cartridge.
a. Simply check whether the hiss continues when you disconnect
the mic, but leave everything else set the same. You might have
to plug something into the mixer board while doing this check if
the mixer switches something internally based on a plug being
present. If so, use a patch cord with nothing on the far end
(drawback: may pick up hum), or a plug with no cord at all
attached (which you probably can find at Radio Shack).
b. Or plug the mic into the Minidisc or DAT recorder directly,
and leave out the (mixer) middle man. It shouldn't matter whether
you include or omit the converter box; use whatever the recorders
need (or borrow yet another adapter if that's what it takes).
2. Microphone. Better mics should be quieter. Substituting some
other mic should produce a different level of hiss if this is your
problem. If the hiss stays the same, step 1 above should have
reduced the hiss dramatically.
