Shure SLXD24+/58-G57 Digital Wireless Vocal System with SM58 Handheld Transmitter

Product Overview

The Shure SLXD24/SM58 is a professional single-channel digital wireless vocal system pairing the SLXD4 receiver with the SLXD2/SM58 handheld transmitter, delivering 24-bit digital audio for live sound, installed AV, and speech reinforcement applications. The SM58 cardioid dynamic capsule is the industry standard for live vocals, combining consistent directional pickup with feedback rejection suited to commercial AV environments. AV integrators specify the SLXD24/SM58 digital wireless vocal system for installations requiring reliable wireless performance with a familiar, field-proven microphone capsule.

Product Description

The Shure SLXD24/SM58 wireless vocal system provides transparent 24-bit digital audio with over 120 dB of dynamic range and 3.2 ms latency—performance well suited to live event production, podium installations, and permanent AV infrastructure. The SLXD4 half-rack receiver uses Digital Predictive Switching Diversity to maintain stable RF reception before signal dropouts can occur, and supports up to 32 simultaneous SLX-D systems within a frequency band. The SM58 capsule’s cardioid polar pattern reduces ambient noise and feedback pickup from stage monitors or loudspeakers in conference rooms and multipurpose venues. The system ships ready for deployment with receiver and transmitter matched to the same frequency band.
