Detailed Description SM57
SM57 is a Shure SM dynamic microphone for instrument reinforcement and recording. Its cardioid pickup pattern focuses on the intended source, with a published frequency response of 40 Hz–15 kHz. The microphone is passive and does not require phantom power.
The contoured response suits drums, percussion and instrument amplifiers. Internal pneumatic isolation reduces the transmission of handling and mechanical noise, while the compact grille supports close placement around instruments.
A balanced three-pin XLR output connects to a suitable microphone preamp or mixer. Placement and distance remain central to tone and rejection. The table below keeps output impedance, open-circuit sensitivity and weight distinct from maximum SPL or preamp-gain claims that are not specified for every model. Consult the manufacturer guide for positioning and accessory information.
