General Description ® Shure Microflex MX391 Series microphones are small, surface-mounted electret condenser microphones designed for mount- ing on conference tables, stage floors, and lecterns. Their high sensitivity and wide frequency range make them especially suit- able for picking up speech and vocals in sound reinforcement and recording applications.
Shure Incorporated Cartridge Polar Patterns RFI Filtering Important: Microphones must be used with the RK100PK or RK202PK plate-mounted preamp to optimize RF immunity. Microphone Placement For best low-frequency response and rejection of background noise, place the microphone on a large, flat surface, such as a floor, table, or lectern.
Do not attempt to detach the cable from the microphone, as damage may result. Preamp Gain If necessary, the preamplifier gain can be reduced by 12 dB. Contact an authorized Shure service center for information. Specifications All measurements taken with microphone mounted on a wooden surface (76 x 76 cm)
