Model 545L User Guide Unidirectional Dynamic Microphone

GENERAL

The Shure Model 545L unidirectional dynamic micro- phone is a low-impedance unit designed for instrument or voice pickup in public address applications. With its attached cable, the microphone is suitable for mounting on an optional A25B swivel adapter, on a fixed pipe or flexible gooseneck, or for handheld use.

The 545L is ideal for use in critical public address sys- tems such as those used in political conventions and legisla- tures, hotels, public auditoriums, stadiums, and churches. The microphone has an exceptionally uniform pickup pattern that provides an excellent solution to feedback problems in reverberant locations, permits best utilization of space in small studios, facilitates orchestral placement, and provides effective rejection of unwanted noises.
