The BLX288/B58 Wireless Dual Vocal System includes two Beta 58A transmitters. The Beta 58A dynamic vocal microphone is precision-engineered for live performance and project studio recording. A tailored frequency response accentuates vocals, and the supercardioid pattern isolates from other sound sources. It combines simple setup and an intuitive interface for performance you can trust in. For performers who wish to unplug from the wire, BLX Wireless Systems feature trusted Shure microphones and world-class design and construction. The durable BLX88 offers simple setup, intuitive controls, and microprocessor-controlled internal antenna diversity. One-touch QuickScan frequency selection quickly locates the best open frequency in case of interference. For use with BLX Wireless Systems. Dual analog wireless receiver provides improved linearity and frequency response with group and channel scan for easy set-up. Features include microprocessor internal antenna diversity, frequency QuickScan, and two-color audio status indicator LED.

Big sound. Full sound. Sophisticated sound. Is your mic living up to the power of your vocal? For decades, the BETA 58A has been through the ringer, pushing voice to the forefront on the biggest stages in the world. For sound that commands the attention of the entire crowd, this is your microphone. On stage or in studio, the BETA 58A is made for refined voice. The brightened midrange and bass roll off give lead and background vocals a mighty presence in the mix. And the supercardioid pattern works harder to isolate your sound from every other source in the air. You could say it's a singer's best friend. The Shure BETA58A dynamic microphone is precision-engineered for vocals in professional live sound reinforcement and studio recording applications. A tailored frequency response accentuates the clarity of vocals, and a tight, supercardioid pickup pattern ensures high gain before feedback, maximum sound isolation, and minimum off-axis tone coloration. The BETA58A is ideal for close-up lead and background vocals, especially in high sound pressure level (SPL) environments. A proven shock mount system, hardened steel-mesh grille, and superior build quality withstand the rigors of daily sound reinforcement.
