Audio Technica AT4033/CL Microphone

The Audio Technica AT4033/CL Microphone is a side-address fixed-charge condenser microphone featuring a cardioid polar pattern. It is designed to meet the most critical acoustic requirements of professional recording, broadcast and sound reinforcement.

The Audio Technica AT4033/CL Microphone offers exceptional transient response and clean output signals. A studio classic and bluegrass favorite, the Audio Technica AT4033/CL cardioid studio condenser is the microphone that broke the US$1000-barrier in its class. It is the latest edition of the legendary side-address AT4033 microphone featuring low-noise, symmetrical, transformerless circuitry that results in exceptional transient response and clean output signals. A strong up-front presence characterizes the sonic signature of this 40 Series pro-audio classic. The Audio Technica AT4033/CL’s 80Hz high-pass filter easily switches between flat frequency response and a low-end roll-off that diminishes ambient noise and popping with closely-miked vocals. Includes the AT8449 shock mount for superior isolation.

What We Think

This is one of my favorite mics of all times. It is a clean and natural mic, and pretty much just gives you what you give it. It does a bit of a smoothed out top end, but it is well balanced, and does not come off dark - there is still good detail and clarity in it. I will typically grab this for acoustic instruments, backing vocals, piano, and drum overheads. Anywhere you want a smooth but honest capture of the sound source, without having to worry about proximity effect, this is a great mic to reach for. I've always loved Audio Technica Mics, and this one has been a favorite for many years now.

    if you only have one mic then this one

    Posted by Headphonomenon on May 16th 2012

    This is the mic I always recommend to home and project studio owners who are looking for one mic to do it all. For the money you can't go wrong. It is clear and open and sounds good on a wide variety of different sources. I have had three for almost a decade and they are rock solid.

    Audio Technica AT4033/CL

    Posted by Steve Cruz on Aug 30th 2011

    This is a workhorse microphone, worthy of a place in every mic cabinet right alongside bread and butter mics like SM57s.

    An excellent choice for many sources, I've had success with the 4033 on acoustic guitars, electric guitar amps, congas, bongos, djembes, tambourines,triangle, shakers and more than a few female vocalists. On a few of those sources, it beat out microphones almost 10 times the price!

    If you need a mic to help bring a source "forward" in the mix, this might be the perfect fit.

    I give 5 stars because it's such a great value, and the package here includes AT's sturdy shockmount and a protective case.

    Every mic locker should have one of these.

    Posted by jay matheson on Jan 21st 2011

    This mic may not be the best for every situation but I've never really heard it sound bad. i have used one of these for a long time. it's works well on screaming vocalists, female and gang vocals. it's pattern is a bit wide so I wouldn't use it where isolation is an issue. if a singer likes to move around a lot though the wider pattern is a lifesaver. this mic often gets the call during sessions leaving the 2000$ mics in the dust.

    great on acoustic guitar/vocals

    Posted by Thomas Szy on Sep 28th 2010

    Honestly, i think this is the best LDC mic that one can buy for the money. Acoustic guitar comes across detailed with good transient representation, but without being harsh. Similarly, vocals are smooth and present, but without that terrible siblance that are found on a TON of other LDC's in this price range. Best bang for the buck i've discovered in a long time

    Excellent in the mix, for some can be a bit harsh

    Posted by Michelangelo Trujillo on Jul 26th 2010

    The 4033 was the go to mic in my studio for years, simply because I didn't have any other LDC's. I recorded over 60 albums and demos with it, through API, Neve 9098, TLA Classic series, and other mic pre's, often in to a distressor. I used them with success on acoustic guitar, vocals, and drum overheads. It wasn't until I started expanding my mic collection that I really understood the place the 4033 occupied in the sonic palate. By comparison, it's high end content can appear to be a bit harsh, aggressive, or sharp, and certainly more present then some other mics. This can be good if you're going for a produced rock sound, and has worked very well for me and always translated wonderfully in the mix. It's definitely a great sounding mic and even when I AB it with mic's I use more often now I still think it's an excellent mic.

    Great all-around mic for budget home recording

    Posted by Todd on Mar 4th 2009

    I purchased this mic a couple of years ago to do some demo material. At the time, I was using mostly SM57s for all applications. Truth be told, the 57s were working out great. But to capther the nuances of a quiet vocal or acoustic guitar part, I needed a decent condensor. I'd borrowed several of the popular mid-level condesor mics at one time or another, but decided to get the AT4033 on recomendation of an engineer friend. I honestly believe that, for the price, you won't beat this mic. Without coloring the signal, it captures intricate details that you would only expect from a high end condensor. I've used it an many varied applications and found it to be extremely versatile as well. Normally, I'm a big proponent of "You get what you pay for", but in this case, I'd say you get a little more.
