The 920B has a wide, flat frequency response which provides unsurpassed, natural, transparent sound quality and warm sound when used close to the sound source. Its cardioid pickup pattern minimizes annoying feedback when used close to sound reinforcement speakers and monitors, while reducing the pickup of unwanted off axis sounds. The approximate overall length is 20 inches.
