    The Beta 27 is ideal for a wide variety of acoustic, wind and electric instruments, such as guitar and bass amplifiers, drum, percussion and piano. The tight supercardioid polar pattern ensures high gain-before-feedback and provides maximum isolation from other sound sources making it perfect for live stage applications.

     

    Đặc điểm nổi bật :  Micro Shure BETA 27

     

    • Supercardioid polar pattern specifically targets the sound source consistently with greatly minimized bleed from off-axis sound sources
    • Tailored for superior transient response from a low-mass, 1” externally-biased, ultra-thin 24 Karat gold-layered Mylar® diaphragm
    • Flat, neutral frequency response for natural reproduction on stage or in the studio
    • 3-position switchable low-frequency filter helps reduce unwanted background noise or counteract proximity effect for consistent, extended lowend
    • 15 dB switchable attenuator handles extremely high SPLs with ease
    • Premium electronic components and gold-plated internal and external connectors
    • Internal pop filter with three separate mesh layers reduces wind and breath noise.
