Shure BETA 57A Microphone Instrument Dynamic Lo Z Supercardioid Mic BETA57A
Shure SM57A Dynamic Microphone
Product Information:
The Shure Beta 57A®
is a high output supercardioid dynamic
microphone designed for professional sound
reinforcement and project studio recording.
It maintains a true supercardioid pattern
throughout its frequency range. This insures
high gain-before-feedback, maximum isolation
from other sound sources, and minimum
off–axis tone coloration.
Excellent for acoustic and electric
instruments as well as for vocals, the
extremely versatile Beta 57A dynamic
microphone provides optimal warmth and
presence. Typical applications include
drums, guitar amplifiers, brass, woodwinds
and vocals.
