Came to let everyone know it works. I plugged my mic into my pedal board. Used a line to xlr into the mix input of my interface. Routed everything as normal in the DAW and it was there. The pedals provide the 48v alone. Just match levels accordingly.Personally I have five pedals:Eq, comp, distot, delay, reverb. All work perfectly fine. Just like a guitar.Using to save powrr on computer for lighter recordings. Hope this helps.

Work as it should definitely need to have in the mic box

The impedance converter works great. It brings out the true sound quality and level of the intended. Great product.

I had gotten a few off brands of these and they don't work. Shure is a name professional musicians know and trust. Yeah it's $20, but it's a gotta have tool in your arsenal.

I've bought my first harmonica, a Hohner crossover marine band in the key of C, which I highly recommend.I have a Fender Hotrod Deluxe amp and a shure sm58 microphone, so I needed to plug the low impedance balanced mic thorough a converter to high impedance unbalanced one, and this is exactly what this transformer does .

Works as expected. I don't have a PA setup. Everything goes thru my headphones, so I wanted to hear my mics thru a clean amp. Works fine. Obviously not a great way to project one's voice, but it works.

I believe this shure xlr xformer is mosty used for attaching a mic to a 1/4" mixer input or directly to an effects pedal. I'm writing this for anyone that may be considering something similar to how I'm using it. I have a TC-Helicon PlayElectric vocal/guitar processor and I'm running the guitar through the XLR output (dual mono - vocal/guitar) rather than guitar through the 1/4" out. The XLR output is connected to an XLR splitter cable. One of the splits goes directly into an XLR input on my mixer. I've put the Shure impedance matching xformer on the other split of the XLR cable and this line goes into ElectroHarmonix Freeze, C9 & M9 effects pedals. I had attempted this configuration with something I thought was an impedance matching xformer I had lying around (unbranded/unlabled). It kind of worked but the results were erratic when trying to set levels. The Shure xformer solved the problem and sounds really good.Just to note: I also tried this config using 1/4" TS out from the guitar processor with a TS splitter cable running one side into the 1/4" input on mixer and the other into the EHX effects but it just didn't sound as good to me.
