really need help...

[morelli]

Is it possible to convert an unbalanced signal from a stereo miniplug from a sony ecm909 mic, to dual xlr plugs? I have this sony microphone, and an audiosport duo, which has 2 xlr inputs, and I need to find a way to connect them. Thanks for any information!

On your Miniplug wire the tip to pin 2 of one of the XLRs , wire the ring teminal (half way up the plug) to pin 2 on the other XLR. the sleeve then gets connected to pins 1 & 3 on both XLRs.

Hope this helps

You can also get get some adapters to get you there. Use a mini stereo to dual 1/4" then 1/4 to XLR.

more trouble

Ok, so I have a 1/8 to dual 1/4 converter already, and I just came back from radio shack with two 1/4 to xlr converters. I plugged everything into my audiosport duo, and tried recording. Unfortunately, the signal is far too quiet, even with gain set to max and everything. I think it is because the radioshack converters say "High impedance to low inpedance" even though my mic is really a medium impedance. Any advice? Would manually wiring the 1/8 to the two xlr's like previously suggested avoid this? Thanks...

Rewiring would solve that or get adaptors without the transformers.

Is that a condensor or dynamic mic? Dynamics need more help from the preamp and that could also be a problem.

It is a condenser mic- 1 kilo ohm impedance, according to manual. What exactly would I need to do to wire these? Just plug a wire into the xlr inputs and tape the other end to the jack? Would it be easier to wire it from the dual 1/4 jacks than from one 1/8 stereo jack, and if so, could you repeat the instuctions for those? I'm really sorry to ask such annoying questions but I have a deadline coming up and I have been trying for weeks to get a good recording system set up, and I just got this relativley expensive and not-easily-returnable audiosport duo machine; I just want to get it working. Thanks so much for your help!

one more thing

I forgot to mention- I hear that 1 kiloohm classifies it as a "medium" impedance mic, although the audiosport manual says that the xlr imputs are for "low" impedance. Am I going to destroy my audiosport by plugging these in? the manual also says: input impedance 2.4 kohms.

You probably wont hurt anything with the load. Wilkee gives a pretty good description on the wiring. I cant add to much to that.

I would suggest getting different adapters because a poor solder job will cause you many more headaches in the future.

What are you recording? My guess is that mic is more for video and live ambient recording. You might be going through a lot of effort for a mic that wont get the job done.

If you tell us what your desired end result is for the project maybe we can suggest some cost effective alternatives.

 

[morelli]

I am recording classical double bass for an audition tape. I'm afraid the only adapters I can find are at radio shack, and they are all the same: High impedance to low impedance. If medium impedance wont hurt low impedance inputs on my audiosport preamp, I think I'll try the wiring solution- i can get plugs and jacks of both types there for fairly cheap. But, if someone can suggest a cost effective solution, Id love to hear it.

Basicaly, my situation is: Need to record double bass for audition tape (or cd, whatever) by feb 15. My cassette recording sounds really horrible, and my sound card (which i can't even determine the maker) sounds worse. I have this brand new audiosport duo, which seems like the perfect solution, dual mic preamps and bypasses sound card altogether (via USB), but its mic inputs are in xlr form, not the stereo miniplug output of my mic, and also my mic is slightly higher impedance than expected by the audiosport. Thanks for all the advice!

 

[TexRoadkill]

My guess is that the mic will sound less than stellar but I could be wrong. If they are looking more for performance than sound quality it probably doesnt really matter.

The fact that it is medium impedance seems to suggest it is a video camera mic or something.

You might do a search on CLASSICAL or DOUBLE BASS and see what mics are recomended. You might get away with a $70 pair of Berringer ECM8000's or you may want to get a large condensor but that will run you a few hundred bucks.

I have never recorded double bass so my recomendations are really just semi-educated guesses.

 

[morelli]

I see- I'm afraid its no longer really in my budget to get another microphone, so for now I'm just going to try to get the one I have to work with my audiosport. I returned the converters that were lowering the impedance so much, but I need advice on what to get in order to wire that custom converter (they dont sell any that dont have the transformers). Can someone give me a descripition of how to do it? Radioshack sells tons of plugs and jacks and wires and I want to make sure I do it right. Thanks!

here's what you gotta do:

get a 1/8 to 1/4 TRS converter that goes on top of your 1/8 TRS microphone plug and turns it into a 1/4 TRS male plug.

then get a TRS female to female converter that you can plug your 1/4 TRS male plug into.

then get a regular TRS to dual 1/4 TS (ie... Y) cable. you can then either plug the 1/4 TS from the Y cable into the audiosport duo's 1/4 inputs, or buy 2 direct boxes that convert your 1/4 signal to XLR.

but that sure is a lot to do! too bad no one makes a direct converter from 1/8 stereo to 2 x 1/4 TS

at leas the audio technica stereo mic comes with converter plugs
