Description:
The new Engineered Sound. Contractor-exclusive innovations for every acoustical challenge. And safe haven from RFI.

This super-compact, small-diameter gooseneck delivers flexible positioning with a sleek, low-profile appearance. The mic’s low-profile element provides a uniform MicroLine polar pattern with narrow 90º acceptance angle. It is equipped with an 80 Hz low-cut UniSteep® filter that reduces pickup of low-frequency ambient noise and a mute switch with an LED that lights when the mic is on. The microphone offers unsurpassed immunity from radio frequency interference thanks to UniGuard® innovations.

• Designed for quality sound reinforcement, professional recording, television and other demanding sound pickup applications
• Mute switch in base lights to indicate operational status of the microphone
• Low-profile element provides uniform MicroLine polar pattern with narrow 90º acceptance angle
• Unobtrusive design with an overall length of only 12.45" (316.3 mm)
• Plugs into any standard XLRF-type connector, or direct mounts to 5/8"-27 stands using included thread-mount adapter
• Included shock mount attenuates noise, shock and vibration transmitted through the mounting surface
• Available interchangeable elements permit angle of acceptance from 90º to 360º
• Small-diameter gooseneck permits highly flexible positioning while maintaining smooth, contoured appearance
• 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
• RoHS compliant—free from all substances specified in the EU directive on hazardous substances
