Detailed Description SM7B
SM7B is a Shure SM dynamic microphone for voice recording, broadcast and studio production. Its cardioid pickup pattern focuses on the intended source, with a published frequency response of 50 Hz–20 kHz. The microphone is passive and does not require phantom power.
SM7B combines a broad response with bass-rolloff and presence-emphasis switches, electromagnetic hum shielding and an integrated suspension system. The standard and close-talk windscreens support different working distances. Suitable low-noise preamp gain is important for quiet speech.
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.
