Large diaphragm, side-address cardioid condenser microphone for stage and studio applications. Features a 3-position LF filter switch, low-mass Mylar® diaphragm, 3-layer mesh windscreen, and 15dB pad.

Flat, neutral frequency response for natural reproduction on stage or in the studio

15dB pad for performance consistency across a wider range of high SPL sources

Superior transient response from a low-mass large Mylar® diaphragm

Uniform cardioid pattern for superior off axis rejection

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
