Shure BLX288/SM58 – Dual Wireless Vocal System

Product Overview

The Shure BLX288/SM58 is a dual-channel analog UHF wireless vocal system for commercial AV installations, houses of worship, and multi-presenter spaces. It combines the BLX88 dual receiver with two BLX2 handheld transmitters and the industry-standard SM58 cardioid capsules, supporting two simultaneous wireless microphones from a single receiver. This dual wireless microphone system suits integrators who need two coordinated channels with proven, dependable vocal capture.

Product Description

This dual-channel wireless vocal system pairs two SM58 handheld transmitters with the BLX88 dual receiver for conference rooms, auditoriums, training rooms, and worship spaces that need more than one microphone. The legendary SM58 cardioid capsule is tuned for vocals and rejects off-axis sound for dependable feedback control across both channels. The BLX88 receiver consolidates two channels into one chassis and outputs to a house mixer or DSP for clean AV system integration. Each transmitter runs up to 14 hours on two AA batteries with an operating range of up to 300 ft (100 m) line of sight. The system is available across multiple frequency bands (H9, H10, H11, J11) so AV system designers can coordinate two clean RF channels. For a Beta 58A capsule version, see the Shure BLX288/B58.
