The Shure ULXD4Q is a four-channel digital wireless receiver in a single rack space, doubling the channel density of the dual-channel ULXD4D. AES-256 encryption, 24-bit / 48 kHz uncompressed audio, and Dante optional output make it a touring-grade option that's become a default on broadcast and rental shop riders.

Product overview
Start with the payoff, then work through how it functions, where it fits, and the details that change a real build.
The payoff
Wireless Mic decisions, organized around the whole rig.
The ULXD4Q is Shure's answer to channel density in a single rack space: four independent digital wireless receivers, each accepting a bodypack or handheld transmitter, all packed into 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. at 305mm deep. It doubles the channel count of the dual-channel ULXD4D and has become a standard line item on broadcast and touring ridersThe document attached to a booking that lists what the band needs — inputs, monitors, power, backline (and the green-room snacks). precisely because it stops you from burning rack space on separate single-channel receivers. If your show has a band plus presenters, or a theater production with multiple cast mics, this is the unit that lets you build a complete wireless solution without the rack growing out of control.

How it works in the path
At load-in, the cascade antenna ports are what save you time. A single pair of paddleA directional antenna (paddle, LPDA, helical) aimed at the stage — focuses coverage where the performers are and rejects RF from elsewhere. antennas can feed multiple ULXD4Q units chained together, so you're not running separate antenna distributionsOne pair of antennas feeding many receivers through an amplified splitter — replaces the forest of whips and keeps RF levels consistent. for every box — though you'll still want to respect the cascade limits and signal levels when you start stacking more than a few units. The DanteThe most common audio-over-network standard: dozens of channels of uncompressed digital audio down one ordinary Ethernet cable between Dante boxes. output is genuinely useful: all four channels appear on the network simultaneously, giving you a clean, labelable digital feed to your console or stageboxThe I/O endpoint on stage: mics plug in there and one digital line (AES50, Dante) carries everything to the console.

At 30W typical and 40W maximum draw, four channels for roughly one amp on a standard circuit is reasonable overhead. AES-256 encryption is there if you're working corporate or broadcast and someone on the production side asks about RFRadio Frequency — the wireless part of wireless. RF planning is why big rigs scan, coordinate, and combine antennas instead of hoping. security.

Where it earns its place in the rack
This unit belongs in a rack that already has ULXD transmitters or is committing to that ecosystem — it does not pair with ULX or QLX series gear. If you only need two wireless channels and budget is a real constraint, the ULXD4D is the honest alternative. If you're running eight or more channels regularly, two ULXD4Q units with cascaded antennas is a cleaner build than mixing receiver form factors. The $6,950 price positions this firmly in the touring and rental tier; a regional theater or house-of-worship rig with occasional wireless needs should weigh that honestly against total channel demand before committing.
In the rack
Details worth deciding before load-in.
Use the Antenna Cascade Out to feed a second ULXD4Q rather than splitting your antenna feed passively — you preserve signal integrity and keep the chain organized at load-in.
Assign all four DanteThe most common audio-over-network standard: dozens of channels of uncompressed digital audio down one ordinary Ethernet cable between Dante boxes. channels at the start of the day and label them in your Dante Controller session before soundcheck; if you also run the XLRThe standard 3-pin locking connector for mics and balanced line signals — pin 1 is the shield, pins 2 and 3 carry the balanced pair. outputs to an analog split, you'll have a fallback path without any rewiring mid-show.
At 305mm deep, the ULXD4Q sits flush in a standard shallow tour rack — verify your rack depth before assuming you can fit it in a shallow utility case with cable management behind it.

AD4QThe AD4Q packs four Axient Digital receiver channels into a single 1U rack space with full Dante, ShowLink, and Quadversity support, making it the ultimate high-density wireless mic solution. For large touring productions and broadcast events with many wireless channels, this dramatically reduces the rack space and antenna infrastructure needed. The price per channel is significant, but the reliability and feature set are unmatched in professional wireless.View gear →
ULXD4DThe Shure ULXD4D packs two full digital wireless channels into 1U, with Dante-networked outputs in addition to analog XLR and 1/4" — rack two and you have four wireless channels in 2U with a single Cat5e back to the console. The industry standard for mid-to-top-tier corporate, theatre, and touring rigs, edged out only by the Axient Digital line at the highest end.View gear →
ULXD4DThe ULXD4D dual-channel mic receiver packs two ULX-D channels into a single rack unit with native Dante output, streamlining integration into networked audio systems. Having two channels in one unit halves your rack space requirements compared to single-channel receivers, which matters in dense multi-mic deployments. The Dante output feeds directly onto your audio network, eliminating the need for separate analog-to-digital conversion.View gear →
