CAD Audio A77USB Cardioid Condenser Side Address Microphone
Vintage Design That Speaks Volumes
The iconic look of the classic Astatic A77 side-address microphone hearkens to a heyday of sorts for broadcast and live performance. To celebrate the 65th anniversary of this iconic design, CAD Audio is here with the A77USB Cardioid Condenser Side Address Microphone to bring that same evocative look to the modern day. Now featuring cutting-edge circuitry and a handy USB-powered driver cardioid-pattern condenser to work perfectly for live vocals, podcast, or even streaming if you want that old-school look. The 48 kilohertz, 16-bit resolution is plenty for the on-board DAC to capture most recording scenarios with proper detail and the frequency response that covers from 50 Hz to 16 kilohertz means the microphone is ideal for the human voice or a variety of transient instruments.
