The Crown CM-310A and CM-310ASW Differoid ® microphones are hand-held noise-cancelling microphones for live sound, clubs, sporting events or other applications with high ambient sound levels. These microphones are noise-cancelling, rejecting sounds that are not close to the microphone and have a cardioid polar pattern. They may be switched to flat or rising response. They permit extremely loud PA levels before feedback occurs and also reject unwanted background noise. The CM-310ASW features a smooth, silent magnetic reed switch that turns the mic on and off.
