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.

I am Smitten with this Mic

I rarely give any reviews a 5 but I am just in awe to this microphone. I just bought another one for a stereo set up. I read that the precision of these microphones are almost exact. I have had my first AT 4047 for at least 5 years now. I was a litte apprehensive of buying a new one due to the differences of a "broken-in" mic and a new one. But I can say I am pleased with the match since I have tested them with a piano set up. Very warm and catches every nuance. They sound very similar if not matched. Vocals on softer songs, I always go to this mic instead of the AKG B-ULS (which I use for more progressive vocals). Also, I use this as a room mic when I am recording amps (with a Heil PR30 snug to the grill and a Royer 101 8 inches away). It gives a great mix between the 3 mics. Overall, I am totally pleased with this Japanese microphone that really has a great vintage mixed with modern vibe.

The AT4047/SV is a great Condenser for vocals and acoustic guitar. It utilizes a transformer in the output like some of the great mics of the past. Not tinny sounding like some of the over-priced Neumanns,which offer no pad or hi pass, and has great rich sound. This mic will surprise you if you've used cheaper AT models. IT"S NOTHING LIKE AN AT4040. A/B it against anything, it'll stand up ! it's awesome on male and female vocals. Kudos to AT !!!

Who needs a vintage pre amp!

First let me say, I like AT mics. I own 2 2035's I got for $95 each which are true externally polarized condensers. They work extremely well as drum overheads...if you know how to place them and do some very selective EQing to taste. I also have a 2050 I like for it's versatility. Both mics are incredible values and would be at twice the price, being fairly flat, get back what you put in type of unclouded sound that is rare at the price. The high end on these mics, while fairly present, does not have the brittle, harsh sound many chinese mics can emit. They are also very consistent in quality and specs making it easy to make a matched stereo pair. But this is about the 4047SV. I just wanted to admit my bias. Like every one else, this mic is very different for AT. If you are a fan of the Golden Age Pre73, you don't need it with this mic. I have used it primarily for vocals and voice over type work. I couldn't believe how good it sounded through an SP VBT-1. It actually made the pre amp sound better...I was able to get a fairly warm and as someone else said, very "smooth" sound using little or no tube blend. Through a Focusrite Pro 40, it also sounded very good.and while Saffire pres are very quiet and clean, they do impart a very slight but musical bit of coloration. The 4047Sv again just took the sound of the pre to creamy levels. It essentially did the same thing through a 710 Twinfinity. It was very easy to get a good sound and it seems taking a little extra time finding the right sweet spot for different individuals/uses both with the roll off on and off saves a lot of time as little (if any!) EQing will be necessary. Like the others, I am very happy with this mic and plan on getting a 4047MP next.

Sweet Vintage Character

I got this mic a couple months ago and I have been blown away by the quality of the sound. Its got a darker, thicker sound to it than most condensers, which is perfect for a more coloured vintage sound. Vocals sound huge and this is the first mic I've had absolutely no problems with sibilance with! I've recorded acoustic guitar with it, and it sounds great although you'll get a very thick sound as well, so it takes up a lot of room in the mix. I'd definately reccomend it for male vocals seeking a smoother, classier sound.

Sweetwater Advice

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!
