The new Engineered Sound. Contractor-exclusive innovations for every acoustical challenge. And safe haven from RFI. With durable construction and unobtrusive appearance, the ES933ML offers versatile solutions for speech, theater, orchestra and choir sound reinforcement and recording. The microphone's low-profile element provides a uniform MicoLine polar pattern with narrow 90º acceptance angle. Available in two colors: black (ES933ML); white (ES933WML), the microphone offers unsurpassed immunity from radio frequency interference thanks to UniGuard® innovations. The ES933ML also offers an 80 Hz low-cut UniSteep® filter that reduces pickup of low-frequency ambient noise. Features: Designed for quality sound reinforcement, professional recording, television and other demanding sound pickup applications Small size and excellent response are ideal for suspension over choirs, instrumental groups and theater stages Low-profile element provides uniform MicroLine polar pattern with narrow 90º acceptance angle Available interchangeable elements permit angle of acceptance from 90º to 360º Superior off-axis rejection for maximum gain before feedback Requires 11V to 52V DC phantom power UniGuard® RFI-shielding technology offers outstanding rejection of radio frequency interference (RFI) Integral UniSteep® filter provides a steep low-frequency attenuation to improve sound pickup without affecting voice quality Available in two colors: black (ES933ML) and white (ES933WML) RoHS compliant-free from all substances specified in the EU directive on hazardous substances ELEMENT Fixed-charge back plate, permanently polarized condenser POLAR PATTERN MicroLine® FREQUENCY RESPONSE 30-20,000 Hz LOW FREQUENCY ROLL-OFF 80 Hz, 18 dB/octave OPEN CIRCUIT SENSITIVITY -35 dB (10.0 mV) re 1V at 1 Pa IMPEDANCE 250 ohms MAXIMUM INPUT SOUND LEVEL 133 dB SPL, 1 kHz at 1% T.H.D.
