Description

The 545SD is a classic Unidyne III dual-impedance dynamic microphone that has been a mainstay in live sound and recording since its introduction. Its cardioid polar pattern provides uniform pickup with 15-20 dB of rear rejection, making it effective for instrument miking and public address applications. The built-in silent magnetic reed on/off switch with a lock-on option allows the microphone to be permanently set to the "on" position when desired.

Classic Design

  • Unidyne III cartridge: The same iconic moving-coil element that defined Shure's legacy, delivering warm, natural instrument reproduction
  • Dual-impedance operation: Switchable between low impedance (150 ohms) and high impedance via solderless connector change
  • Silent magnetic reed switch: On/off switch with lock-on option eliminates switching noise during use
  • Chrome-plated die-cast body: ARMO-DUR grille and stainless steel screen for lasting durability
  • Uniform cardioid pattern: Consistent directionality across the frequency range with excellent feedback rejection
