I haver been reading a lot about the beachtek adaptor and was considering it, but what does it do that this way cheaper alternative above doesn't do? Is there a quality difference or just that it has 2 inputs, which I don't need. I just want to be able to use the handheld mic I already own.

Thanks in advance!!!

FYI I have a 1/4' to mini jack adapter already

I use this one for on camera use. Hosa Technology | Mini Stereo Male to 3-pin XLR | XVM-101F | B&H (http://www.bhphotovideo.com/c/product/158476-REG/Hosa_Technology_XVM_101F_Mini_Stereo_Male_to.html)

I make my own. And hundreds of other people have apparently made their own also, judging from the popularity of my web page...

The Beachtek has isolation transformers in it so the mic line is balanced, those cables do not. Also some of the Beachtek units supply phantom power, those cables do not. If you have a mic that needs phantom power then the cables are useless. If you have a dynamic handheld mic and you only need to use it with a few metres of mic cable then you will possibly be OK using an unbalanced mic line.

That said I'd really avoid putting a 3.5mm to 1/4" adaptor into a camera and then pluging a 1/4" to XLR cable into that. Thos 3.5mm sockets are pretty weak and replacing one could be expensive. Better to get a lighter cable or use solid velcro cable ties for strain relief near where the cable goes into the camera.

Both of those adapters will unbalance the connection, maybe not a problem if you are camera mounting the mic, but anything more than that is a bad idea. The Hosa looks like shoddy construction to me (most of their stuff is junk), with the poorly made female XLR end. Using a quarter inch adapter with the Centrios adapter is just asking for trouble.

Using a transformer box like those made by SignVideo and Beachtek is the way to go. For one thing, it will protect your mic input if somebody trips on the cable, plus it keeps the connection balanced.

If you must get an unbalanced adapter cable, at least get one with a Neutrik connector:

Pro Co Sound | Mono Mini Male to XLR Female Cable - 5 | SHMXF-5 (http://www.bhphotovideo.com/c/product/404075-REG/Pro_Co_Sound_SHMXF_5_Mono_Mini_Male_to.html)

Mogami | Gold Stereo Mini Male to 3-Pin XLR | GOLD-XLRF-MINI-018 (http://www.bhphotovideo.com/c/product/483163-REG/Mogami_GOLD_XLRF_MINI_018_Gold_Stereo_Mini_Male.html)


Better to stay balanced with the Shure A96F, which has a transformer and blocks DC voltage:

Oh great Marco, that's just what I wanted to hear, my cable is a piece of junk. :) I'm kinda dense when it comes to audio. I guess for 10 bucks you don't have to be to smart to figure out it's made cheap. Good to know Hosa stuff is low quality though.....for next time.

Well hey if it's working, don't sweat it. Just keep an eye on the connection. Also, I just noticed that the Pro Co cable I linked to is mono only, so that's not a good one to get. It will probably route the signal to just one side and possibly cause interference, so apologies for posting that link.

thanks a lot for the replies guys. maybe it might be worth the extra cash after all, at least I will get a cable that is balanced and already has the minijack connection like that $65 one that was suggested.
