Manufacturer's Description for Shure PGX14 UHF Headset Wireless System with WH20 Microphone

Shure PGX Wireless Series
Created for active musicians and presenters who also manage their own sound, Shure PGX Wireless improves your performance and simplifies your setup. Innovations such as automatic frequency selection and automatic transmitter setup make wireless quicker and completely worry-free. PGX systems now feature Shure's patented Audio Reference Companding, delivering the crystal clear sound quality that pro audio engineers trust. It's the best-sounding, simplest choice in wireless, from the leader in live performance sound.

Shure WH20TQG Headset Microphone
The Shure Model WH20 is a rugged, lightweight, dynamic headset microphone that provides high-quality voice pickup. It fits securely for active microphone users, such as aerobics instructors and musicians, with low visibility for stage appearances. The WH20 is suitable for any voice communications application where comfort and reliability are required.

The WH20 has a cardioid (unidirectional) pickup pattern. This provides greater gain-before-feedback and isolation from ambient noise and other unwanted sound sources, such as air-conditioning, musical instruments and loudspeakers. A carefully shaped frequency response includes a voice-frequency presence peak and a low-frequency rolloff to compensate for the proximity effect inherent in cardioid microphones during close-talk operation.

An integrated elastic CROAKIES headband secures the headset comfortably. The headband, wireframe,and gooseneck are adjustable to accommodate any head size or shape.
