Shure SLXD124+/85M-G57
The Shure SLXD124+/85M is a dual-transmitter wireless system that brings wireless freedom, system control, and world-class Shure audio to performance, broadcast, and location sound events. Built on Shure's SLX-D+ platform, it carries the SLXD family's reputation for trouble-free wireless audio production forward.
Its 24-bit digital audio engine captures every detail with transparent precision, using the full 118 dB dynamic range to produce a faithful reproduction of any source. RF performance stays locked in, even when the spectrum gets crowded, thanks to ShowLink®, which scans, updates, and manages interference automatically. Mobile monitoring puts oversight of the system in the palm of your hand from anywhere in the venue.
The system includes an SLXD4+ receiver, an SLXD1+ bodypack transmitter with WL185m lavalier microphone for discreet speech, and an SLXD2+/58 handheld transmitter with the iconic SM58® capsule. Each piece is engineered for resilience, from reinforced connectors to a low-profile lavalier that resists sweat and makeup.
