- One of the recent trends in pro audio is the abundance of low-cost medium to large
- diaphragm condenser mics that have become available in the last year or two. Not too
- many years ago, you could separate the large professional studios from the small project
- studios by the quantity and quality of large diaphragm condensers in the mic closet,
- mainly because they used to cost so much.
- In the last year, the sub-$500 condenser mic market has exploded. There are a lot of mics
- to choose from in that range--some good and some not so good. As I was in the market
- for a side-address medium to large diaphragm condenser, I looked at a lot of spec sheets.
- I wanted to find the best mic that I possibly could for the lowest price possible. Based
- upon that criterion, I immediately gravitated to the Audio Technica AT3525.
- With a list price of $399 and a street price in the $250-300 range, the AT3525 seemed to
- be a lot of mic for the money. It is a back-electret cardioid design that reportedly uses the
- same capsule as the popular (and more expensive) AT4033. The difference seems to be
- in the internal electronics since the 4033 specs out a bit better (although the 3525 specs
- are really good). It requires a 48V phantom power supply (there is no battery option) and
- it comes with a very effective shock mount that allows you considerable positioning
- latitude.
- I hooked the AT3525 up to my Mackie 1202VLZ and engaged the phantom power. I
- then performed some comparisons between a Shure SM58 (which is a good "baseline")
- and the AT3525. Compared to the SM58, I found the 3525 to have a much smoother
- sound, much better transient response, extended low-end response, much more air and
- transparency on the high-end and a less "peaky" midrange. You can run this mic
- completely flat or with a minimal amount of EQ.
- While not a Neumann U87, the AT3525 sounded somewhat similar to the U87 (based on
- recordings I have made with that mic), at least on my voice. Both mics exhibit a fairly
- flat response (the Neumann is obviously flatter) and broad midrange peak so that may
- explain the similarity in sound. Considering the price differential, that is quite a feat!
- As far as applications, I would expect that the AT3525 would be great for vocals,
- acoustic guitar, various other acoustic instruments and drum overheads. It is a wonderful
- mic that is hard to beat at that low price!
