dynamic microphone question

i have two inputs on my audiointerface. (it's e-mu 0202 USB).
one is MIC IN, with phantom power, and another is line/guitar in. (it says Hi-Z in, does that mean high impedance?).
both inputs are with on-board preamps. they both work as line inputs exactly the same.

now my question. can i use dynamic microphone with the line input? will it be as good as if i'd put it in dedicated MIC IN?
it think that would be cool to mic a guitar with two mics in stereo, but i'm not sure if that will work with my audiocard.

thanks.

You have ONE mic input which can be used as a line or guitar input instead and ONE line only input (guitar or line).

Hi-Z = high impedance = guitar/bass.

You could plug a mic into the R input but it'll sound shit because:
a) the impedance won't match
b) as a result you probably won't be able to dial the Gain high enough to get a decent sound.

You could just buy a box or small mixer to preamp the mic and then inject that into the line in, or just get another Audio Interface with two mic preamps, like this:

right, thanks for quick response. i think i'll get mic preamp/di box or something like that. changing audio interface is not an option at the moment.. (actually CBA to do this).

Get one of these from radioshack or whatever:

I had a similar thing with my Line6 Toneport. It has 1 xlr mic input, and then a guitar input and 2 line inputs (1/4"). Only the mic input had a knob to adjust mic gain. I first tried my mic in the line inputs and guitar inputs because i couldnt find an xlr cable but, because there wasn't a knob to increase the mic gain, the recordings came out really quiet- even with the onboard preamp at full volume. Then when I got hold of an XLR and went in through the mic input it all worked well and using the mic gain i got good clear and loud recordings.

I think Mike said that anyway, but there's an anecdote.

what is it?

it's an impedance adapter for converting a low-z XLR signal for a hi-z 1/4" input.

kool. i think this is the way. thanks.

i googled on "impedance adapter" and found this: http://homerecording.com/impedance.html
