| MPC22 Ceiling Condenser Microphone | |
 |
The acoustical boundary microphone MPC 22 is designed for mounting into tabletops
and ceilings. The half-cardioid polar pattern is aimable and assures high-gain-before
feedback. The high sensitivity guarantees a constant output level even from long
distance sources. Elastic bearing rings achieve mechanical isolation from the mounting
surface and therefore offer effective sound isolation of the microphone. • High gain-before-feedback • Flat, wide range frequency response • High-quality reproduction of speech • Unobtrusive design • Ceiling or tabletop mounting • Fast and easy installation |
