CardioidAKG Acoustics C451 Anniversary

Cardioid Pencil Condenser Microphone

AKG’s “65th Anniversary” edition of the C451B is a cosmetic upgrade to the C 451 B.

Both mics are electret pencil mics designed to recreate the sound of the discontinued C451 EB with CK1 cardioid capsule. Onboard switches allow selection of a 3-way high-pass filter (flat, 75Hz, 150Hz) and 3-way pad (0dB, -10dB, -20dB).

The Anniversary Edition is finished in a semi-gloss black finish called “Titan.” It ships with the SA60 stand adaptor and W90 foam windscreen, in commemorative packaging.
