Gear-heads and audio enthusiasts, I’ve got another mic demo for you. Third in this series of videos, this one checks out a couple of large diaphragm condenser mics by Audio Technica: AT2020 vs. AT4033a (an earlier edition of the newer AT4033/CL).

The AT2020 gives a great bang for the buck. It avoids a very common drawback of condenser mics in its price range – that infamous high frequency glassiness you get with on-axis recordings. I was surprised by how little de-essing was required. Its self-noise was a bit more evident in comparison to the AT4033a, but nothing I’d worry about, even in an acapella setting.
The AT4033a provided an even more pleasing result around the highs with a slight emphasis on the low-mids. Combined with being the quieter mic, that’s definitely something I’d prefer to work with. Having said that, if you’re running a home studio on a budget, the AT2020 isn’t far behind and would be a great way to start your mic collection.
