Shure BLX288 Dual BETA58A Wireless Vocal System with J11 Frequency

Get crystal-clear sound for your live events! The Shure BLX288/B58 is a budget-friendly wireless handheld microphone system for two presenters, teachers, or lecturers. It offers quality sound right out of the box, along with simple setup and dependable performance.

• Quality Sound: Features Beta 58A dynamic capsules for crisp vocals with a brightened midrange and bass roll-off. The neodymium magnet provides heightened sensitivity, and the supercardioid polar pattern minimizes background noise. The built-in pop filter reduces wind and breath noise.

• Easy Setup: Includes a compact and lightweight BLX88 dual-channel tabletop receiver with internal antennas. The receiver has one-touch QuickScan frequency selection to quickly find a clean RF channel in case of interference.

• Long Battery Life: Provides up to 14 hours of continuous use with four AA batteries. Up to 12 mic channels can operate simultaneously in each frequency band.

This system is perfect for live performances and events in small venues like wedding halls, houses of worship, as well as conference, educational, and corporate facilities.

Optimized for Vocals and Speech

The Beta 58A dynamic capsules are designed for clear vocals. They have a brightened midrange and bass roll-off to control the proximity effect. Each capsule has a neodymium magnet for high sensitivity and output, and a tight supercardioid polar pattern to reduce background noise and feedback. The dent-resistant steel mesh grille is durable, and the built-in pop filter ensures clear speech.

Lightweight Handheld Transmitters

The durable BLX2 handheld transmitters are lightweight and ergonomic, making them comfortable to hold. Group- and channel-selection buttons allow for easy frequency matching with the receiver. Other features include an on/off button, adjustable gain control, and a black identification cap. The WA621 Color ID Caps kit is available as an accessory.

Easy-to-Use Dual-Channel Tabletop Receiver

The BLX88 receiver uses a microprocessor-controlled internal antenna feature to improve wireless audio quality and reliability. Two LED displays show group and channel settings, and four LED lights indicate system readiness and incoming audio signal strength. It has two 1/4' and two XLR outputs for connecting to PA systems and mixing boards.

A Versatile System to Meet Your Needs

Shure offers a BLX1 bodypack transmitter compatible with various lavalier, instrument, and headset microphone options. This allows you to adapt your BLX system as your needs change.
