ATM31a
Common name: Audio-Technica ATM31a

The ATM31a is ideal for close-up vocals, overheads, piano and strings. The microphone sound is similar to far more expensive studio microphones. Its low-mass diaphragm ensures minimum distortion and the cardioid pattern provides added warmth when used close up.
