HypercardioidAKG Acoustics C 747

Hypercardioid Condenser Microphone

The AKG C 747 is a miniature (5.4-inch) hypercardioid shotgun microphone with an electret condenser element.

The mic is remarkably small — just 9mm in diameter, less than half the diameter of its own XLR jack. Although it uses an interference tube and is billed in some contexts as a “shotgun” microphone, its nominal hypercardioid pattern provides only 5-10dB of rear rejection at most frequencies. Attenuation at ±90° is approximately 8dB, not significantly better than most Cardioid mics (which attenuate 6dB at 90°).

The mic’s self-noise rating is 21dB, with a max SPL of 133dB.

A switch on the mic body provides a high-pass filter (-12dB/octave @ 150Hz).

It includes the H 47 isolation mount, the W 70 windscreen, the MSH 70 “Short gooseneck,” SA 47 stand adapter, SA 80 clamp, and SHZ screw link.

The AKG Acoustics C 747 is also known as: C747, C 747.
