CARDIOID WIDE RANGE FIXED CHARGE CONDENSER BOUNDARY MICROPHONE
Engineered Sound microphones have been the first choice of leading contractors and system integrators at the highest level of broadcast and installation. Includes UniGuard™ RFI immunity protecting the microphones from any RF interference from mobile phone beeps to laptop buzzes. The discreet size and look of the engineered sound microphone means the best quality of sound is available with the least visibility. Includes gooseneck microphones with interchangeable capsules, ultra low profile boundary, hanging, lavalier clip-on and handheld microphones.
This low-profile cardioid condenser boundary microphone is recommended for unobtrusive table-, ceiling-, or panel-mount applications in high-quality sound reinforcement, professional recording and teleconferencing. Designed for permanent installation, the microphone is equipped with a self-contained power module with an XLRM-type output connector, eliminating the need for an external power module. Protected by a rugged all-metal case with a two-layer steel mesh grille, the microphone has a cardioid pattern for enhanced gain before feedback and improved signal-to-noise ratio. It is available in two colors: black (ES947) and white (ES947W).
