CAD Audio is shipping the classic A77 vocal microphone originally introduced by Astatic in 1959. The A77 is a large diaphragm, side address dynamic microphone that has been updated with a PowerGap™ high gauss magnet and a TrueFlex™ diaphragm. In addition to its stylish “retro” cosmetic appearance, the A77 delivers a high-powered, articulate sound that cuts through the mix in any live situation. Originally described as a “high fidelity uni-directional cardioid microphone,” the A77 featured a wide dynamic range for that time of 30-15,000 Hz. CAD is also introducing the A77r microphone to bring the unmistakable vintage ribbon sound of the past to a range of modern vocal situations. The A77r features a large ribbon element surrounded by PowerGap high gauss magnets that immediately sets the mic apart in terms of warmth, clarity and a full-bodied sound.
