Well, the old timers here know I'll show up, because I am one of the leading advocates of this mic. BTW, if at all possible, try to find a deal which includes the H100 or H85 shock mount, which are among the highest quality, most versatile shock mounts made anywhere, and they are too damned expensive to buy by themselves. First, you will hear the C2000B variously referred to as a small diaphragm mic, and a mid sized diaphragm mic. For reference, large diaphragms are usually about 1" or a little larger, small diaphragms are about 1/2" or smaller, and the rare mid-sized diaphragm mics, such as Audio-Technica AT4033, are about 3/4". The C2000B is a 1/2" diaphragm, but is mounted to a larger retainer. I consider it a small diaphragm mic, but because of the way the diaphragm is mounted, it performs more like a mid sized diaphragm mic.
First, some history, second, a little tech, and lastly, the real world result, IMHO. The C-series contains lots of mics. It is just a designation for an externally polarized condenser mic. The C414, for example, in many incarnations, has been a studio standard for years, mostly for instruments, and occasionally for vocals. When AKG entered the budget mic market, their offerings included C2000B, C3000B, C4000B, and C1000S. None of these mics *truly* suck, but there are better mics out there for the money, in virtually every case, excepting the 2000. The C1000S, in particular, I really dislike, and I'm not a big fan of C3000B, either. The C4000 is a pretty good mic, but then you're into enough money that there are many mics in that range I'd rather own. Everybody figured that if a C3000B kind of sucked for $300, a C2000B must suck *more* for $200, so the mic didn't sell very well, and almost nobody ever listened to it, in spite of the fact that unlike its siblings, it got universally positive reviews. Meanwhile, it caught on a little bit in Europe, and found uses in orchestral recording and on live sound stages. It was originally designed as a live instrument mic, and then re-directed at the home recording market. The worm has begun to turn a bit, as folks are starting to get tired of the hyped high end sizzle of the standard crop of cheap Chinese mics, and have started to realize that the little mic *doesn't* suck at all. It doesn't sound like a Chinese mic because it *isn't* one.
Tech-wise, the thing has a ruler flat response from 100Hz to 6kHz, and a mild bump that maxes out at +2db at 10kHz. That is a definition of a flat mic.The max SPL handling is 140db, or 150db with the pad engaged, and they aren't kidding. The little bugger is hard to clip, and it doesn't feed back much in a live setting. Signal to noise ratio re 1 Pa (A-weighted) is 74db, which makes it not the quietist mic on Earth by a long shot, but compares well to other small diaphragm condensers. The high pass filter cuts 6db/octave below 500Hz, and is actually the only thing I don't like about the mic. The bass cut is radical, and I virtually never use the thing. I can see how it would be useful for something live, like a flute with a drum kit 10 feet away, but in the studio, I don't use it.
Now, in the real world, what is it good for? First, it doesn't suck on *anything*. It is pretty good on vocals, male or female. It has a user-friendly gradual proximity field, and is not prone to popping or sensitive to sibilants. It is very good on acoustic guitar, mandolin, piano, sax, woodwinds, and strings. It is excellent as a pair for drum overheads, toms, conga, djembe, and as a stereo pair for ensemble recording. It is simply the best mic I have ever used for cabs, which surprised the hell out of me. So, what do I use them for? One, as a stereo pair, for remote recording. They are cheap enough to take them where I don't want to risk a pair of Neumanns. Secondly, one of them is used anytime I'm mic'ing a cab, usually in conjunction with a dynamic. Often, the dynamic isn't used in the final mix. It's just there to make the client think I know what I'm doing. He wants to see a dynamic? I'll give him one.
Thirdly, it is used wherever the mic I want to use isn't available. If I just need one more mic for anything I can think of, I'll put one up. I've never used it on kick, or bass cabs, but a couple of reviewers did, and it worked, which doesn't surprise me. Overall, I would call the C2000B the most versatile entry-level condenser on the planet. Just don't buy a C3000B because you figure for more money, it must be better.-Richie
