Professional cardioid dynamic vocal microphone developed to cut through high onstage levels. Rugged, with durable construction, it is not sensitive to handling noise. The e 840 efficiently suppresses sounds emanating from outside its pickup angle and is fitted with a hum-compensating coil for reducing electromagnetic interference. The Sennheiser E840 features frequency-independent directivity and is built with a rugged metal housing and shockmount capsule.
