The Shure BLX14/PGA31 brings presenters, instructors, clergy, multi-instrumentalists, and live performers a cost-effective wireless headset microphone system with quality sound, simple setup, intuitive operation, and dependable performance right out of the box. It includes the compact and lightweight BLX4 single-channel tabletop receiver with internal antennas, ideal for portable use.

The BLX14/PGA31 also includes a PGA31 cardioid headset mic with windscreen and a bodypack transmitter. The headset's wearable design offers both comfort and a secure fit for hands-free operation. The receiver features one-touch QuickScan frequency selection to quickly search 123 available frequencies and locate a clean RF channel in case of interference. The system provides up to 14 hours of continuous use with two AA batteries, at a range up to 300'. Up to 12 mic channels can operate simultaneously in each frequency band.

This streamlined system is well suited for speech and vocal performance in small music venues, wedding halls, and houses of worship, as well as conference, educational, and corporate facilities.

Comfortable Headset Mic Optimized for Speech and Vocals The PGA31 headset condenser microphone is built for comfort and clear vocal reproduction. It features a cardioid polar pattern that helps reject unwanted noise, and a tailored frequency response optimized for speech intelligibility. The flexible gooseneck design with discrete adjustment options let you position the microphone for further source isolation in loud environments. Lightweight Bodypack Transmitter The durable BLX1 bodypack transmitter offers a lightweight, ergonomic design that is comfortable for the presenter to wear. Group and channel selection buttons allow for quick and simple frequency matching with the receiver. Other features include an easily accessible on/off switch, adjustable gain control, and a TA4M 4-pin input jack. Easy-to-Use Tabletop Receiver for Quality Audio The BLX4 receiver employs microprocessor-controlled internal antenna diversity to improve the quality and reliability of your wireless audio. An LED display shows group and channel settings, while two LED lights indicate when the system is ready for use and the strength of the incoming audio signal. The unit offers 1/4" and XLR outputs for connectivity to PA systems and mixing boards.
