Xlr To Minijack Wiring?

Recommended Posts

Hi All,

Just spent the afternoon attempting to wire a stereo minijack to two XLR females to fit my Sennheiser mic which has two XLR male sockets.

I ran Jack tip to XLR Pin 2, Jack ring to XLR Pin 3 and Jack sleeve to XLR pin 1 on both XLRs. Result - one channel in operation and nothing from the other, any suggestions apart from biologically impossible ones would be greatefully received! If anybody knows of a wiring diagram to get two channels of XLR out of one minijack I would love that too!

(I also removed the connections from the sleeves on both without any effect apart from reducing an horrific hum).

Thanks,

Jack

Depends on the mike:

Try tip to pin 2, ring to pin 2 (on the other XLR). Shield to Pin 1 on both. Pin 3 is open.

Alternately, tip to pin 2 of one XLR, sleeve to pins 3 and 1, then connect ring to pin 2 of second XLR and sleeve to pins 3 and 1 again.

This worked: 'Try tip to pin 2, ring to pin 2 (on the other XLR). Shield to Pin 1 on both. Pin 3 is open'.

It's left me with two channels, which is great, but a ground hum, which is not. Someone suggested putting a capacitor in but won't this reduce the signal?

Thanks a/form for that link, it's technically beyond me, but I'm sure I'll get desperate enough to have it translated by someone with a brain.

If my second wiring suggestion doesn't work the simplest approach would be to go pick up an isolation transformer from Radio Shack and hook it up in between to act as a bridge between the balanced and unbalanced portions of the circuit.

Jack,

I should have asked you sooner.

Do you have the MKE 44P? The one that comes with a 5-pin XLRF to dual 3-pin XLRM adapter?

Forget the RS balanced transformers. They will cost you more than a simple Hosa adapter. Hosa YXF-247, YXF-302, or YXF-305 which are 1 foot, 2 feet, and 5 feet respectively all of which sell for around $13.50

Examples:

http://www.bananas.com/productdetail.asp/p...)---2XLR(F)-5ft

You could try a guitar shop, but they may not have those particular Hosa adapters.

Beyerdynamic makes adapter cables that are 5-pin XLRF to 3.5 stereo for their MCE 72 and 82 stereo mics, but they are all special order and relatively expensive:

This is an OLD post , but the Correct wiring would be

Pin2 Left channel = Ring

Pin2 Right Channel = Tip

Pins 1& 3 of each get wired TOGETHER , and go to shield at the Minijack Plug end , that means 1,and 3 are separate from the XLR to the end of the cable , then joined at the Minijack end .

Do NOT leave pin 3 Open , If anything ground pin 3 and leave pin 1 open , There is a Series of articles , one is called "Pin 1 Revisited "

That speaks in great detail about ground Fault and other issues .

Some bad advice was given here in this thread
