The SM35 Performance Headset Condenser Microphone gives multi-instrumentalists the freedom to express themselves without sacrificing sound quality. A tight, unidirectional cardioid polar pattern provides excellent rejection of off-axis sound sources to prevent feedback and signal bleed onstage, whether in use in small clubs, large installations, or arena tours. The SM35-XLR includes an inline RPM626 preamp for use in standard wired (XLR) applications.
