Wiring a mic to xlr cable?

tubesNtweed Joined: Sep 07, 2011 Posts: 507	Posted on Sep 03 2013 12:53 AM Want to retrofit my old Midland mic shell with a newer dynamic mic inside of it. I am stuck on the wiring. It has the two wires coming from the element, and there's an on/off switch. Then I want to wire it to a really short xlr cable so I can attach a longer one for gigs, since the xlr plug won't fit where the old plug was. Does anyone have a diagram for something like this? Basically where would the element's wires connect to the switch, then from there where do I connect to the cable? Where should the cable's ground wire go to, somewhere on the switch? Thanks. It's a 6 pin switch. Top

To answer your question, more info is required re. the capsule (does the mic originally have a 1/4" phone plug and plug into a guitar-level input? Does its capsule have more than two connections available?), as well as the configuration of the switch (how are the six pins connected?). Some closeup "gut shots" would probably be pretty helpful if you can post some. Top

The old mic had a 4 pin to 1/4". I will check on the switch and see if the capsule has more connections. Top

You may not need it, try with and without. — www.cutbacksurfband.com Top
