AKG C430
A 31-gram cardioid condenser that handles 130 dB SPL without flinching. It's a percussion mic that disappears on the stand and stays out of the way of the sound.
Overview
The first thing you notice is the weight, or the lack of it. The C430 is 1.1 ounces (31 g), 3.1 inches long, with a 0.75-inch diameter body. You can clip it to a drum rim or dangle it over a snare and forget it's there. AKG built it as the newest member of the MicroMic Series III. The brief shows in every dimension: small, light, short-bodied, with a response shaped for close-in instrument and percussion work. Contemporary coverage of the small-diaphragm condenser market noted a broader trend toward smooth, European-style small-capsule instrument mics (Mix, 2001, p.35).
The capsule is a prepolarized condenser with a cardioid pattern. AKG's own documentation says the mic "hears" more evenly from the sides. That helps when you point it at an acoustic guitar, a piano, a saxophone, or a percussion rig, all of which radiate sound in every direction rather than from a single spot. The same uniform cardioid behavior gives the C430 usable gain before feedback on a loud stage, which is the environment it was engineered for. The frequency response runs 20 Hz to 20 kHz. Sensitivity is quoted at 7 mV/Pa (-43 dBV) at 1 kHz into a 200-ohm impedance, with a recommended load of greater than 2000 ohms.
Headroom is where the C430 earns its keep. AKG rates it for 126 dB SPL at 1% total harmonic distortion and 130 dB SPL at 3%. That puts it comfortably in snare-and-tom territory with no pad switches. The output is transformerless, and AKG specifically credits it with ultra-low low-frequency distortion, which helps a kick or floor tom read clean. Powering is undemanding: phantom power anywhere from 9 to 52 Vdc, so it runs off just about any interface, mixer, or preamp that offers phantom. Where no phantom is available, the optional B 15 in-line supply allows battery operation. Output is a standard 3-pin XLR-M, the finish is matte black, and the mic ships with an SA40 stand adapter.
Plainly, the C430 is a workhorse instrument mic, not a vocal flagship. The response shaping that makes it excel up close on drums and strings also makes it a questionable first choice for a delicate lead vocal. The tiny body makes placement easy, but it also leaves very little to grip when you swap it between stands in a dark club, so the stand adapter does a lot of the mounting work.
