Electronics Forum / Electronics / September 2007seeking audio adaptor mini xlr - jack
Hi, I'm looking for an adaptor that will connect my Shure lavalier mike (with mini xlr plug) to a quarter inch jack socket on an m-audio microtrack. pictures here: http://www.zen73857.zen.co.uk/mike/ I've tried studiospares, shure, m-audio, no luck. I'll make an adpator if I have to but I'd rather buy a ready made one. Thanks for any help. > Hi, I'm looking for an adaptor that will connect my Shure lavalier > mike (with mini xlr plug) to a quarter inch jack socket on an m-audio > microtrack. > pictures here: http://www.zen73857.zen.co.uk/mike/ > I've tried studiospares, shure, m-audio, no luck.

You will need a custom-made adapter that will take the phantom power supplied by the MicroTrack and convert it to the voltage required by the microphone. AFAIK, this is not available as a commercial item, although is it not rocket-surgery. > Hi, I'm looking for an adaptor that will connect my Shure > lavalier mike (with mini xlr plug) to a quarter inch jack [quoted text clipped - 3 lines] > make an adpator if I have to but I'd rather buy a ready > made one. Thanks for any help. I'm not sure that a passive solution is possible. Offhand, the Microtrack probably supplies only a volt or two of bias, while the Shure lavs require about 12 volts. >> Hi, I'm looking for an adaptor that will connect my Shure >> lavalier mike (with mini xlr plug) to a quarter inch jack [quoted text clipped - 7 lines] > Offhand, the Microtrack probably supplies only a volt or > two of bias, while the Shure lavs require about 12 volts. Of course since the Microtrack provides phantom power, the Shure RPM 628 will bridge the gap. http://www.shure.com/ProAudio/Products/Accessories/us_pro_RPM628_content >Hi, I'm looking for an adaptor that will connect my Shure lavalier >mike (with mini xlr plug) to a quarter inch jack socket on an m-audio >microtrack. >pictures here: http://www.zen73857.zen.co.uk/mike/ >I've tried studiospares, shure, m-audio, no luck.

Thanks for any help. mike --------------------+---------------]|---------- to preamp | 10 uF unbalanced in \ / \ 2.2K ohms | | --- - 9V battery | gnd --------------------+---------------------------- gnd I don't offhand know which polarity the battery needs to be. I believe with the Shure mikes they need to have positive power. Before doing this, first make sure the 1/4" input has enough gain in the first place to deal with a mike level signal. --scott Signature"C'est un Nagra.

You need to establish exactly what is the pinout and power requirements for your microphone. The required circuit is *SOMETHING LIKE* this one... http://www.uneeda-audio.com/phantom/p48t122.jpg which converts P48 phantom to 12V. A similar circuit can be used to produce whatever voltage your mic wants, and to route the power, signal, gnd, etc. as needed. NOTE THAT THE CIRCUIT CITED IS *NOT* EXACTLY WHAT YOU NEED. Without the exact details of your mic, a precise answer is not possible. Do you have the complete model number of the microphone? Do you have the wiring diagram and/or pinout of the mic connector? >> Hi, I'm looking for an adaptor that will connect my Shure lavalier >> mike (with mini xlr plug) to a quarter inch jack socket on an m-audio [quoted text clipped - 20 lines] > you have the wiring diagram and/or pinout of the mic > connector? This appears to show the pinout of your microphone and the wiring of the interface (page 10) ..... http://www.shure.com/stellent/groups/public/@gms_gmi_web_ug/documents/web_resour ce/us_pro_mx1bp_ug.pdf If I am reading it correctly, your mic wants... Pin 1 = ground Pin 2 = power (+6VDC? from a casual glance at the circuit) Pin 3 = Audio out of mic Pin 4 = Pin 3 [dunno why?] You can interface it to the 1/4-inch mic input jacks of the MT2496 with a variation on Rick Chinn's circuit I cited previously. You would need to change the zener diode to limit to 6 volts, and change the wiring where it goes to the microphone head. It seems unlikely that you could fit the required components into either connector shell. > Hi, I'm looking for an adaptor that will connect my Shure lavalier > mike (with mini xlr plug) to a quarter inch jack socket on an m-audio > microtrack. > pictures here: http://www.zen73857.zen.co.uk/mike/ > I've tried studiospares, shure, m-audio, no luck.

The latter can be obtained from www.mcmelectronics.com as part number 27-4140.

(Obvious lesbian joke left to your imagination. :-) But note that the interface between the OP's microphone and the 1/4" mic inputs on the MT2496 takes more than a simple adapter/cable. > > Hi, I'm looking for an adaptor that will connect my Shure lavalier > > mike (with mini xlr plug) to a quarter inch jack socket on an m-audio [quoted text clipped - 6 lines] > > Ebay Item number: 120162286447 That seller doesn't post to the UK unfortunately.
