About the Shure ULXD4Q
The ULXD4Q is the most space-efficient ULX-D receiver, fitting four wireless mic channels into a single 1UThe standard slice of rack height: 1U = 1.75″. A 3U box takes three slices; half-rack gear pairs two units side by side in one. rack space with native DanteThe most common audio-over-network standard: dozens of channels of uncompressed digital audio down one ordinary Ethernet cable between Dante boxes. output. For productions running eight or more wireless mics, the quad receiver dramatically reduces rack space and simplifies antenna distributionOne pair of antennas feeding many receivers through an amplified splitter — replaces the forest of whips and keeps RF levels consistent.. The built-in Dante output means all four channels go directly onto your audio network from one device, making it ideal for dense wireless deployments in touring and installed sound.
The ULXD4Q is Shure's answer to the rack space problem that every touring engineer knows intimately: you need eight, ten, twelve wireless channels, and the receiver farm is already eating half your rack before you've mounted a single power conditionerFilters venue AC, clamps surges, and gives the rack one tidy inlet. Not a voltage regulator and not a battery — just cleaner power.. Four channels of ULX-D in a single 1UThe standard slice of rack height: 1U = 1.75″.

That's the core value proposition, and it's a real one.
At 25 watts nominal draw across all four channels, the ULXD4Q is easy on power budgets — budget roughly 30 watts at peak to be safe, but you're not going to stress a standard rack PDU even with four of these in a row. The shallow 220mm depth means it fits comfortably in a standard shallow tour rack without fighting your antenna cabling.

On a twelve-channel rig running three ULXD4Qs, that's three antenna pairs minimum, ideally fed from a quality active distro like a Shure UA845 or similar.
This receiver belongs in rigs where wireless channel count is high and rack space is genuinely constrained — touring productions, festival packages, broadcast trucks, or any install where you're regularly running six or more handheld and body-pack sources. The native DanteThe most common audio-over-network standard: dozens of channels of uncompressed digital audio down one ordinary Ethernet cable between Dante boxes. output earns its keep the moment you're running a networked console or a separate IEMIn-Ear Monitor — earpieces that replace floor wedges, feeding each player their own mix.

The snake, digitized. for channels that can live on the network. If you only need two channels of wireless and have no Dante infrastructure, the price point here is hard to justify — a pair of single-channel or dual receivers will serve you better. But for the engineer building a high-density wireless rack with a Dante backbone, the ULXD4Q is the efficient choice.
In the rack
- Plan your antenna distributionOne pair of antennas feeding many receivers through an amplified splitter — replaces the forest of whips and keeps RF levels consistent. before you plan your receiver slots — each ULXD4Q shares one antenna pair across all four channels, so a twelve-channel rig needs three dedicated antenna runs from your distro, not twelve.
