Shure SLXD124+85M
The Shure SLXD124+/85M is a combo digital wireless system from the SLX-D+ family that covers both a handheld and a lavalier on one channel. It bundles the SLXD4+ single-channel receiver with an SLXD2+ handheld transmitter fitted with an SM58 cardioid dynamic capsule and an SLXD1+ bodypack paired with the WL185M cardioid condenser lavalier. That gives a presenter a wired-feel SM58 for the podium or a clip-on lav for hands-free work, sharing a single receiver. The system runs 24-bit digital audio with 2.8 ms of latency and a dynamic range greater than 118 dB.
SLX-D+ 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. Bluetooth and Wi-Fi control through the WWB Mobile app, together with desktop Wireless Workbench, let you tune channels and watch RF from a phone. Each transmitter runs up to 8 hours on two AA batteries or an optional SB903 lithium-ion rechargeable pack. Only one transmitter can be active on the channel at a time.
