Shure SLXD4D Dual Wireless Mic Receiver

The SLXD4D is Shure's answer to a very common rack-math problem: you need two wireless mic channels, you have one rack unit, and you don't want to spend touring-system money to get there. It fits the G58 band (470–514 MHz), sits in a full 1U chassis, and ships with both XLR and quarter-inch outputs for each channel — so it will talk to a console's mic input or a direct instrument channel without an adapter conversation at load-in. At $899 for two channels in one unit, it occupies a price tier that makes sense for corporate work, worship installs, and club-level touring.

The shared BNC antenna inputs are the most practically important detail on this unit. Both receivers pull from the same Antenna A and Antenna B connections, which means a single run of coax to your active antenna distribution feeds both channels simultaneously — you're not running four cables to the back of the rack to cover two mics. At 12 watts nominal draw and a shallow 190mm depth, it won't bully a tight rack for space or power budget. The digital RF architecture gives you a fixed 24-bit signal path and predictable, hard-set latency, which matters if your vocalist is also on IEM and you're managing total system delay.

This receiver belongs in rigs where two channels covers the need and the budget is real but not unlimited — a pastor and a worship leader, a presenter and a handheld, a duo act with two vocals. If you're regularly running six or more channels, look at purpose-built multichannel frames like the Shure AD4D or an Axient rack, where antenna distribution and frequency coordination scale more gracefully. The SLXD4D doesn't have dante or AES digital outputs, so if your console workflow depends on networked audio, this isn't your unit. But for analog-in consoles and straightforward two-mic deployments, it's a clean, reliable choice.
