Product Description
ES937aH is a wide-range miniature condenser microphone with a hypercardioid polar pattern. It is designed for quality sound reinforcement, professional recording, elevision and other demanding sound pickup applications. The small diameter double gooseneck design permits highly flexible positioning while maintaining a smooth, wellcontoured appearance. An included snap-on foam windscreen effectively reduces wind noise and “popping.”
The ES937aH is equipped with UniGuard® RFI-shielding technology, which offers outstanding rejection of radio frequency interference (RFI). The microphone is RoHS compliant – free from all substances specified in the EU directive on hazardous substances.
The integral power module can be powered from any external 11V to 52V DC phantom power supply. A recessed switch in the power module permits choice of flat response or low-frequency roll-off (via integral 80 Hz high-pass UniSteep® filter) to help control undesired ambient noise.
