Secret Weapon!

Arguably one of the most underrated microphones in existence. It's my "secret weapon" vocal mic. I have compared it extensively to some high-end Neumann mics. It easily fits in the stable between a vintage U47 and a U67, with hints of a U87 on the top end. Buy two!

Less meddling by engineer (me)

Right out of the box the mic performs with a richness in the upper-midrange where my voice happens to live. This mic was recommended by a seasoned engineer who works with all finest mics in a top studio.

I plugged in to a channel with my standard pro channel settings and it felt very "right". Then I recorded a track and turned off all the previously used plug-ins and it was nearly there without so much as turning a knob.

Love it.

Great Go-To Mic

This was the first "real/pro" mic I bought when I started my own studio 17 years ago. 3 studios later it is still with me. Please believe me when I tell you that this is the mic to have if you can only afford one good mic. I've given that advice dozens of times. Vocals, guitar, strings, horns, or anything you put in front of it sounds great. I've used it on Grammy-winning vocals. A first call Nashville session guitarist once told me it was as good or better than anything he'd ever heard on his acoustic at some prestigious studios. I was doing an accordion overdub at another producer's studio and the 4047 was what he put up. I had to laugh! I told him that's exactly what I use! He proceeded to tell me everything I'd just mentioned here about it being the go-to! You'll never look back after you hear it for yourself.

The affordable reference for vocal recording!

This is-as everyone else stated-an amazingly accomplished vocal recording mic. The combination of transformer -coupled FET sound and the low self noise makes for a very intriguing combination resulting in more resolution of level detail than expected. I've had my heart set on one for a few years and finally acquired it due to the great sale price Sweetwater offered. I wouldn't spend the additional funds on an "accomplished" Neumann. Just my 2c. Cable this right, with at least Mogami Gold quality, and you'll be in good shape!
Thank you!

A PRO MICROPHONE

I've been using Audio Technica microphones since the late '70's. The AT4047/SV has a unique color, there is some boost in the upper mids but not in the highs. My GF bought this mic for me for my birthday because she knew I'd been looking at it.

My voice is Baritone to Contra Alto. This microphone sounds bright on my voice but not in a bad way. I can stack three or four vocal layers with it and it does not sound harsh or strident at all.

I've also stacked it with another bargain AT mic, I've cut a vocal with our AT2035 and then doubled that and then laid two more doubles with the AT4047, the combination of the brightness from the 4047 over the smooth 2035 sounds great, deep and rich. We've had numerous guests and clients ask "what's that effect on your voice?". I never tell.

It's interesting that this microphone and the AT4050 have the same size diaphragm, both are smaller than one-inch in diameter. I have over 50 microphones, lots of high end AKG, a bunch of custom mic's I've built or modded and I can say that this AT4047/SV is getting a lot of use here lately.

One thing I've noticed in over 40 years of recording my own voice, regardless of what microphone I use I still sound like me. Some may make me sound a little better than others but there have been no magic bullets and that goes for the Neumann M149, U87ai, Telefunken U47, Bock 407 and a few other expensive microphones I've had along the way. It all comes down to the source, the microphone just bends it a little along the way.

This Audio Technica microphone bends my voice in a way I like. I also like that it's not tube so there's no external power supply to trip over in the studio.

This microphone does not sound good on my GF, after trying a lot of different microphones on her we've settled on either an old Shure PE54 or AKG B-ULS. I mention this because this AT mic bends her voice in a wrong way, it accentuates something in her upper register that is already loud so it gets made even louder by the AT4047 microphone. She sounds best on a smooth flat response mic like that old 414.

The shock mount for this mic is a little weird but it also works with the AT2035 so that is nice.

I've never had a bad Audio Technica microphone and including all of them since the 70's I've probably had over 20 that I used regularly for live and recording sound. A good consistent product you can rely on.

Good music to all!

What Do Our In-house Gear Experts Think?

Stuart Niven

The Audio-Technica AT4047 is the Audio-Technica microphone with Attitude. It screams quality and character. The FET design characteristics and contoured double diaphragm on the 4047 give a most pleasing sound and vibe to your signal, a colour that will enrich your sounds without over-imposing itself!
