Intended use
Use
Recording and reinforcing loud, transient sources: drum toms and snare, electric guitar and bass cabinets, brass, and broadcast/podcast voice. Its cardioid pattern and marketed feedback rejection suit close-miking on stage and in the studio, and the five-position bass roll-off lets you tame proximity buildup when working close.
Not for
Anyone needing extended top-end 'air' above 17 kHz (its response tops out at 17,000 Hz), such as cymbal overheads or detailed acoustic-instrument capture, and anyone without a decent mic preamp — as a dynamic mic with 2 mV/Pa output it needs clean preamp gain and does not use phantom power.

Description
The Sennheiser MD 421 II is a dynamic microphone with a cardioid polar pattern. It has a frequency response of 30 to 17,000 Hz and a sensitivity of 2 mV/Pa. The microphone includes a five-position bass roll-off switch ranging from an "M" (Music, flat) setting to an "S" (Speech) setting, which reduces low frequencies by approximately 6 dB below 500 Hz. It uses a 3-pin XLR output connector.
