XLR Female To 1/4" Male Line Matching Transformer 6" Cord
XLR Female To 1/4" Male Line Matching Transformer 6" Cord is rated 4.375 out of 5 by 8.
Rated 3 out of 5 by from Should Have Been GroundedI bought 6 of these, and they all buzzed like crazy when installed between a dynamic lo Z mic and a guitar amp input. I took them apart and noticed that the shield on the hi Z side was not grounded to the body of the unit. I soldered a jumper between the shield and the strain-relief clamp, and that solved the problem on all of the units. I think they should have been manufactured this way to begin with. That is why I give them only a mediocre rating.

Rated 5 out of 5 by from Balancing transformer adaptor; great tool!!!!!I have several of these. I'm old school on a lot of things and some old school stuff is still un-balanced 1/4" output (and input). This transformer works very well keeping line losses and noise to a minmum. The six inch cable make it easy and convenient to hook up. I only wish that the other three combinations were available: female XLR to 1/4" female, male XLR to 1/4" male and female connections. I use gender changer adaptors also available from Parts Express. Great place to shop for all my needs. thanks.

Rated 2 out of 5 by from This works; however, I was misled about itI have a 4 channel mixer that has a 1/4 (unbalanced) mic input, while my microphone has an XLR (balanced) output. I purchased this item due to information that I read stating that this impedance-matching transformer is the ONLY way to connect XLR to 1/4" phone jack. It turns out that the information was misleading. My microphone is 500 ohms, while the mic-signal-impedance of the mixer's input is 600 ohms, both LO-Z, so I didn't need an impedance-matching transformer (an added 1/4" plug to XLR mic cable works just fine I later found out); hence, this product does NOTHING aside from giving me a bunch of buzzing through my speakers. It was disappointing for how I was planning to use it, but I will keep the item (I am thankful for the low price) to use with a HI-Z input.

Rated 5 out of 5 by from QualityQuality connectors and durable construction make this a quality item and necessary for your sound equipment box. Get a bunch of them. They're just the thing for the soundman who has to "transform" a low impedance device to high impedance.

Rated 5 out of 5 by from Must have for Ipod through a snakeI love this product, just bought two more.I use a Mackie mixer with two paired channels, i.e. two stereo channels next to the mic input channels. We run a Ipod back to the mixer through the snake and we've found that first there wasn't enough signal to make the run without significant signal degradation. I fixed this with a small sub-mixer on the stage to buffer the run.The next problem was that although the mixer manual says these two stereo channels are optimized for tape/CD/Ipod, I found that the gain cranked wasn't nearly as powerful as using the normal mic channels. It turns out that these channels are for line level signals and although mixer sub-mixer solved one problem it created another, Impedance mismatch.By using these it converts over perfectly and with the 6" cord I can actually get both plugged in without issue. Those non-cord versions of this product won't plug this close together, as noted above by another review.I can only hope these are built as durably as they work.

Which way should the switch be positioned

If I am connecting a low impedence mic signal to the xlr side of the adapter and the 1/4" side is connected to my high impedence input on my mixer, which way to I position the switch to hi imp or low imp. What does the switch do?
Asked by: James 109
This unit does not have a switch on it. IT uses a transformer to match the impedance so nothing is necessary.

how does product work?

So let me get this straight, I would be able to plug a mic such as an sm-57 into this product and plug the 1/4 male end to a line level input of my mackie onyx mixer and be able to get a usable signal from the mic??? Is the pre-amp stage then not needed??? Just wanna make sure this products does what I think it will do before making a purchase. I'm guessing I would be able to add a few more mic lines to my mixer. FYI I am using a Mackie Onyx 1620 mixer (8 mic/line imputs & 8 line level inputs)Thanks!!!
Asked by: thedope
No it s basically an adapter xlr to 1/4 inch so it would only give a usable signal when connected to a mic/line input not a line level.

Why would I get a significant hum using this adapter?

I have connected this adapter between a Shure Sm57 microphone and a HI-Z input mixer. The hum is so significant, the main signal is unusable. When swapped with an existing similar adapter(different manufacturer) the hum virtually disappears.
