Shure BLX14/P31 Wireless Cardioid Headset Microphone System

Product Overview

The Shure BLX14/P31 is a wireless headset microphone system designed for presenters, instructors, and clergy who need hands-free speech reinforcement with freedom of movement. It pairs the PGA31 cardioid condenser headset microphone with a BLX1 bodypack and BLX4 receiver for dependable UHF wireless in conference rooms, houses of worship, and training rooms. This cost-effective wireless headset system suits commercial AV speech applications where the talker needs both hands free.

Product Description

The BLX14/P31 delivers consistent, hands-free vocal pickup for active presenters in commercial meeting spaces and worship environments. The PGA31 is a lightweight cardioid condenser headset that maintains a fixed mic-to-mouth distance, keeping levels stable as the presenter turns or moves. Its cardioid pattern rejects off-axis sound to improve intelligibility and control feedback in live rooms. One-touch QuickScan finds the best open frequency at setup, simplifying operation for AV staff and volunteers. Microprocessor-controlled internal antenna diversity keeps the wireless link stable across the room. The BLX1 bodypack runs up to 14 hours on two AA batteries, and up to 12 compatible systems can operate per frequency band for multi-presenter events.
