PGA31 Performance Headset Condenser Microphone
Overview
The PGA31 performance headset microphone for general, speaking and performance use is a permanently-biased electret condenser microphone. Engineered
to provide maximum versatility and reliable performance in a wide array of conditions at an affordable price, the PGA31 is compatible with any Shure wireless
bodypack systems with TA4F (TQG) connectors. Available as an included option for many systems, it also makes a viable replacement option for use in existing
systems. The wearable design offers improved comfort and a secure fit for hands-free operation in any situation, while the unidirectional (cardioid) pickup
pattern provides excellent off-axis rejection for higher gain-before-feedback when using a stage monitor.
Features
• Wearable wireframe headset fits securely for multi-instrumentalists and active performers
• Permanently charged electret condenser element for detailed, crisp vocals
• Unidirectional (cardioid) polar pattern rejects unwanted noise for improved sound quality and higher gain-before-feedback
• Flexible gooseneck design and discrete adjustment options optimize microphone positioning for further source isolation
• TA4F (TQG) connector seamlessly integrates with existing Shure bodypack systems
• Also available with a wide variety of Shure wireless systems, renowned for ease of use and reliable performance
• Included windscreen tames plosive, breath and wind noise for clean and intelligble sound
• Tailored frequency response primed for great sound on vocals
• Legendary Shure precision engineering for durability and performance
