Electro-Voice PL95A is considered the best dynamic cardioid vocal microphone EV makes, with superb appearance, performance, and durability. It is an excellent choice to control unwanted feedback problems. It has a pass boost designed to be used close up. Handling and cable noise are minimized by a sophisticated shock suspension system. Feedback in live entertainment situations is caused by sound being reflected off walls, and speaker systems, back into the microphone. The PL95A's smooth, peak-free frequency response helps control feedback problems. Feedback problems can be further minimized by using close miking techniques on all microphones.
