  • Multi-Purpose Microphone Shure SM27-SC

    Features: Multi-Purpose Microphone Shure SM27-SC

    • Uniform cardioid pattern for superior off axis rejection
    • Superior transient response from a low-mass large 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 low-end
    • Durable metal construction.
    • Three separate mesh layers reduces wind and breath noise.
    • 15dB pad for performance consistency across a wider range of high SPL sources
