Shure BLX1288/P31-J11 Wireless Microphone System

The Shure BLX1288/P31-J11 is a dual-channel wireless microphone system built for presenters, worship leaders, performers, and anyone who needs the flexibility of two different microphone types operating simultaneously. The package pairs a BLX2 handheld transmitter fitted with a PG58 dynamic capsule — well-suited for vocals and speech — with a BLX1 bodypack transmitter and PGA31 headset condenser microphone, ideal for hands-free presenting or performance. Both transmitters feed into the BLX88 dual-channel receiver, which can manage both signals independently with dedicated volume and mute controls for each channel.

Operating in the J11 frequency band, the system provides a 300-foot line-of-sight range and supports up to 12 simultaneous channels for larger multi-mic setups. Each transmitter delivers up to 14 hours of continuous use from a pair of AA batteries, reducing the worry of mid-event power loss. The BLX platform is designed with simplicity in mind — one-touch frequency scanning and QuickScan technology help find the best available frequency automatically, making setup fast even for users without deep RF experience. While it sits in Shure's entry-to-mid performance tier rather than their premium ULX-D or Axient lines, the BLX1288/P31-J11 delivers the dependable build quality and sound Shure is known for at an accessible price point.
