The SHURE's 596LB is a low-impedance omnidirectional handheld microphone with a push-to-talk button. This paging microphone is built with a rugged, high-impact casing for usage in industrial and commercial applications such as dispatch, police enforcement, construction, forestry, transportation, and mobile public address. It can be utilised in situations where extended cable lengths are required or when there is a lot of hum noise. The unterminated four-conductor lead wire provided by the microphone's coiled cable is used to link the microphone and the switching relay.
