Shure SLXD14+85M
The Shure SLXD14+/85M is a digital wireless lavalier system from the SLX-D+ family, pairing the WL185M low-profile cardioid condenser lavalier with the SLXD1+ bodypack transmitter and the SLXD4+ single-channel receiver. The WL185M clips discreetly to a lapel, and its cardioid pattern favors the wearer's voice while rejecting off-axis room noise, making it a clean choice for presenters, worship, and video. The system delivers 24-bit digital audio with only 2.8 ms of latency and a dynamic range greater than 118 dB.
The SLX-D+ platform widens the tuning range to as much as 138 MHz, opening up to 11 compatible channels in a single 6 MHz TV band, and adds embedded Digital Feedback Reduction to catch feedback before it starts. Bluetooth and Wi-Fi control through the WWB Mobile app, alongside desktop Wireless Workbench, let you set channels and monitor RF from a phone. The SLXD1+ bodypack runs up to 8 hours on two AA batteries or an optional SB903 lithium-ion rechargeable pack.
