The new Engineered Sound®. Contractor-exclusive innovations for every acoustical challenge. And safe haven from RFI. The ES905CL is designed for quality sound reinforcement, professional recording, television and other demanding sound pickup applications. Its rigid-pipe design with ball-in-socket base permits flexible positioning, while its durable metal base mounts to a table, desk or podium with included hardware. The attached wire mesh windscreen with internal pop protection effectively reduces noise from P-pops, wind, and ventilation air currents. The microphone offers unsurpassed immunity from radio frequency interference thanks to UniGuard® innovations. The ES905CL also offers an 80 Hz low-cut UniSteep® filter that reduces pickup of low-frequency ambient noise. The microphone’s low-profile element provides a uniform cardioid polar pattern with a 120º acceptance angle. Power module included.
