Overview

Wireless that works as hard as you do. The SLXD14D+ system brings wireless freedom, system control, and world-class Shure audio to all your performance, broadcast, and location sound events. Standing on the shoulders of Shure's venerable SLXD platform, the SLXD+ carries the torch of 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®, your invisible assistant that scans, updates, and manages interference before you even notice. And with mobile monitoring, your phone is your command center, giving you oversight from anywhere in the venue.

Inside the case: the SLXD4D+ dual-channel receiver and two SLXD1+ bodypacks awaiting your choice of instrument cables, lav mics, headset mics or any combination you desire (sold separately). Every detail speaks of reliability, every feature is designed for the realities of live production.
