Specification Sheet
MODEBL BETA 58A
DESCRIPTION
The Shure BETA 58A is a high output supercardioid
dynamic vocal microphone designed for professional
sound reinforcement and project studio recording. It
www.DatamShaeient4tUa.icnosma true supercardioid pattern throughout its
frequency range. This ensures high gain before feed-
back, maximum isolation from other sound sources,
and minimum off-axis tone coloration. The BETA 58A
has a shaped frequency response that is ideal for
close-up vocals. The superb performance of this
microphone is not affected by rough handling
because of its rugged construction, proven shock
mount system, and hardened steel mesh grille. Typi-
cal applications for the BETA 58A include lead vocals,
backup vocals and speech.
Features
S Frequency response tailored for vocals, with brightened
midrange and bass rolloff to control proximity effect
S Uniform supercardioid pattern for high gain before
feedback and superior rejection of off-axis sound
S Neodymium magnet for high signal-to-noise output
S Hardened steel mesh grille that resists wear and
abuse
S Advanced pneumatic shock mount system that
minimizes transmission of mechanical noise and
vibration
S Minimally affected by varying load impedance
S Legendary Shure quality and reliability
