The BETA 87A is a special breed of condenser microphone. Sporting a highly consistent supercardioid pattern with null points at approx. 125 degrees. These null points mean you can get great isolation from other singers and instrumentalists, as well as from stage monitors. Do you handle the microphone a lot, and vary it's distance while singing? Well this mic is for you! With a low roll off proximity effect the BETA 87A allows you to get in close to the mic and not distort your voice with that boomy quality we often associate with closeness to a microphone. The BETA 87A has a vary wide dynamic range of pickup as well, up to 117 DB!
