The AKG C400BL is a hypercardioid boundary microphone intended for capturing speech. With it's contoured frequency response, the C400BL is particularly useful for meetings, conferences, interviews, speeches, and more. The tailored frequency response features a low frequency roll-off below 200Hz, a high frequency rise centered at 6 kHz and a high frequency roll off at 6kHz.
The contoured frequency response is designed to maximize vocal intelligibility while minimizing noise caused at the low and high frequency registers. The C400BL features a miniature profile for easy concealing and a 5 foot (1.5m) cable with 3-pin XLR output connection. The C400BL's condenser element is powered via 9 to 52V DC phantom power
Contoured Frequency Response
With a low frequency roll-off, high frequency roll-off and mid frequency peak, the C400BL is optimized for speech and vocal reproduction.
Hyper-cardioid Polar Pattern
The hypercardioid polar pattern is effective in minimizing ambiance and off-axis audio.
Dual Noise Cancelling (DNC)
The combination of a narrow pickup angle and contoured frequency response further reject ambient noise.
The small, unobtrusive profile allows for easy concealment.
The C400BL features a repaintable surface that aids in concealing the microphone from view.
