Detailed Information:

87A type is a first-class quality of dielectric capacitor microphone heart-shaped handheld voices, the frequency response and smooth level (SPL) processing ability. For professional loudspeaker, broadcasting studio recording application, and 87A both excellent performance, travel and the strong production.
87A features a controllable rolled-off proximity effect, can compensate, and can prevent close often occur when the pickup banging." With special performance improvements to the high frequency area for more bright timbre. Compact model of 125 ° in the heart near zero, can maximize the isolation of other singer or instruments, but will minimize interference from the axis. Beta 87A Beta using illusion source.
Beta 87A - including stents adapters. Cables are not included.
The frequency response, smooth, gradual display
The super high equilibrium, heart-shaped pickup pattern can provide excellent feedback before
To compensate, electronic rolled-off proximity effect
Dynamic range, wide (117 dB), low distortion
For rf interference, the sensitivity and electromagnetic hum is very low
The microphone, advanced head shock absorption system can reduce mechanical shock and take hold of the noise
, the built-in "banging" sound filter can reduce the wars and need not breathing
For years, the performance, reliable smoothly
