XLR vs. Mono? dynamic mics

I have a M-Audio firewire solo which has one XLR input and one mono/instrument in. what is the difference between XLR and 1/4" instrument input?

I really need this one answered....
Can I run a dynamic mic into the 1/4" instrument (unbalanced) input? (for micing guitar amp)

And the 1/4" instrument input is unbalanced while the XLR is balanced, what does that mean?

it'll be more noizy than using the xlr input...i'm gonna take a stab and guess the 1/4" cable is permanatly attached to the mic, or you're using one of those xlr to 1/4" adaptor cables....

basically, if the mix is xlr, use an xlr input

Yeah... I will be using an adaptor cable.

well, i wouldn't say it would be more noizy, that seems a little extreme.

the xlr (balanced) cable and connections reject noise that's introduced from the cable (and adjacent devices). So if an unbalanced cable is used, with no introduced noise, then they'll both be quiet.

xlr cables can also be run for much longer distances without degradation than can a single signal cable.

lotsa people use unbalanced cables. in short runs, away from interference, they do fine.

Yes, you can run a dynamic into the 1/4" input. 1/4" inputs can be balanced as well. They use a stereo jack (also known as TRS) for the two signals.
