Reissuing a classic patented design for its 85th anniversary, CAD has drawn upon this patent to release the A77, a large diaphragm dynamic side-address microphone operating in a supercardioid pattern. It is capable of capturing frequencies between 30 Hz and 15 kHz, and can handle sound pressure levels of 150 dB and more. Its vintage design has been given a few updates though—a PowerGap high gauss magnet and a TrueFlex diaphragm—in order to bring a modern, articulate profile to the original construction.
