OmnidirectionalCardioidBidirectionalAKG Acoustics C4000

Multi-Pattern Condenser Microphone

The black C4000 is a repackaged version of AKG’s C 4000 B. The specs for these two mics are identical.

Both mics are multipattern FET condensers with switchable pads and filters. Both use a one-inch edge-terminated electret capsule, and transformerless electronics.

Like the rest of AKG’s “project studio series” mics, the new C4000 is finished in a matte dark gray. It ships with the H85 elastic shockmount and the W4000 windscreen. The SA61 mic clip is available separately.
