The Audio-Technica ATM21SM is a cardioid dynamic microphone designed for instrument pickup in both live and studio settings. Built around a moving coil design, it delivers a full-range response with a focus on clarity at close distances, making it well suited to amps, percussion and vocals alike.
Its unidirectional pattern helps control feedback and reject off-axis noise. An internal windscreen and blast filtering reduce breath and handling noise, and the low-impedance output pairs easily with mixers and recorders. Housed in a rugged, low-reflectance body with a built-in cable and XLR connection, it's made for reliable use on stage or in remote recording setups.
