The MXL USB.006 Cardioid Condenser Microphone has an extremely smooth, natural sound typical of what you'd hear on a professionally produced CD or radio show. Completely plug and play, the MXL USB.006 doesn't skimp on quality with a gold-sputtered diaphragm and 20Hz-20kHz frequency response. It even has a 3-position, switchable attenuation pad that makes it easy to configure this mic to just about any sound source.
