The Shure Microflex MX393C Cardioid Condenser Boundary Microphone is a surface-mounted electret condenser microphone designed primarily for mounting
on conference tables, stage floors, and lecterns. The MX393C has high sensitivity
and wide frequency range making it especially suitable for picking up speech and vocals in sound reinforcement and recording applications. Interchangeable cartridges provide the installer with greater flexibility and make it possible to easily reconfigure microphone coverage as the need arises. The Shure MX393C includes an internal pre amplifier, a programmable membrane on/off switch, an on/off indicator
LED, and a miniature, four pin connector.
Shure's MX300 Series microphones take advantage of the principle that, at
a barrier or boundary, the sound pressure level doubles. When placed
near a sufficiently large boundary surface, the microphone has 6 dB
higher sensitivity and approximately 3 dB greater direct-to-reverberant
sound ratio.
