Dynamic mic into RH1 mic input?

[j-dawg]

A guy posted this question on the T-Board and I'd kinda like to know the answer too:

Can you run a dynamic mic (say, a Shure SM57) into the RH1's mic input? With the correct adapters of course...

A) First and foremost I guess, would the plug-in power coming from the mic jack harm the 57 or interfere with the signal, since dynamic mics obviously don't need or use power.

If no harm comes from A, then is the RH1's preamp strong enough to get a usable signal from the 57?

Thanks for any advice!

I have plugged a Shure Beta 58 dynamic into my minidisc (I have an Rh1 and a MZ R30) via an xmlr to male mini 1/8 inch cable. Works fine. There is some noise - not too objectionable for speech especially if its in the field. It would probably be better with a different preamp

I haven't noticed any damage to the mic or minidisc.

Dynamice mics that are XLR will tolerate the full 48 volt Phntm power of a mixing board . The MD is out puting 3volts or so at about 29 milliamps . Some dynamics will have higher output than others, the 57 and 58 are known for sturdyness not output.

Any mic will "Work" in the mic input with the correct adaptor but a proper cable will give better results

XLR- 1/8 wiring

Take a good 1/8 -1/8 stereo cable about a meter long ,cut off one end . Buy an XLR plug for the mic from Radio Shack or a music strore ( cost you about 5 bucks) Nuetriks are my favs. Very carefully strip the cover off the cut end of your cable.Exposing a Sheild wire and a Red wire , and a White wire. strip off just about 1/8 inc of the cover of the red and white wire, solder them together, Open the XLR plug , take the sheild wire and wire it to pins 1 and3 and the case tab, of the plug and the RED/WHITE goes to pin 2 , this will take your Balanced Mono microphone , and send it to both Channels of the MD .

and will take the negative out of pin3 and ground it so there wont be interference.

Awesome advice you guys! Thanks a ton! This isn't for me, and I don't necessarily have any need to plug an SM57 into a minidisc recorder, but you just never know when something like this could come in handy. I will relay these messages.
