Stellar Reception for Your SLX-D+ Setup The SLXD4D+ packs an impressive amount of dual-channel functionality into a space-saving half-rackmount unit. For starters, you get the SLX-D+'s system-wide 24-bit/48kHz audio conversion and a 118dB dynamic range for crystal-clear audio performance. To boot, onboard Digital Feedback Reduction promises disruption-free reception — complete with AES-256 encryption for enhanced security. Moreover, a dedicated ShowLink Ease control link ensures lock-tight synchronization, enabling you to manage interference, scan for new channels, and automatically update for clear transmission. You can also monitor and configure your setup using a paired mobile device via WWB software and Shure's mobile app.
