Shure AD4D-NP

The AD4D-NP is Shure's Axient Digital two-channel receiver in a no-accessories package, meant to expand a rack you already own rather than start a new one. Each of its two channels runs true digital diversity across a tuning range up to 184 MHz, so it locks onto clean spectrum and holds it in crowded RF environments. Standard and High Density (HD) modes let you trade range for channel count when a show needs dozens of simultaneous systems.

ShowLink gives real-time remote control of ADX transmitter settings from the booth, and each channel offers switchable XLR and AES3 outputs plus Dante over a configurable Ethernet switch for redundant digital audio. Because it is the NP (no accessories) version, it ships with fewer extras than the standard AD4D: the dual-channel receiver, locking power and jumper cables, a rackmount kit, and the user guide. It is offered in A (470-636 MHz), B (606-810 MHz), or C (750-960 MHz) tuning bands.
