Shure ULXD4Q
Diagnose a wireless channel by separating tuning, receiver audio and the output route.

Ask GLMedia about rental or purchase options and advice on a compatible configuration. Availability, configuration, location, price and terms are confirmed for your request.
Model and application
- Receiver channels
- 4
- Analog audio
- XLR mic / line
- Network audio
- Dante
- Synchronization
- IR
- Output options
- Direct / Audio Summing
This is the quad ULXD4Q. Record its regional band and firmware; do not apply ULXD4D channel counts or assume every ULX-D band combination works.
Connections and required equipment
Transmitter → receiver RF/audio → direct or summed XLR/Dante → console. Wireless Workbench control is separate from a successful audio subscription.
Room and recording outputs: decide before summing
For a conference, decide whether you need each voice separately or an already combined mix. A track per speaker supports later balance decisions; a finished mix serves a different brief. Agree the deliverable before choosing cabling.
Audio Summing changes both XLR and Dante outputs. Switching connections cannot separate voices already summed in the receiver. To retain individual sources, verify Audio Summing OFF and each channel’s mapping before rehearsal.
If the room needs a mix but recording needs separate voices, keep channels separate into a console or recording system with enough routing, and build the agreed destinations there. Decide whether recording follows faders and mutes; room balance changes should not affect it accidentally. The actual options depend on the chosen system.
XLR connects to suitable analog inputs: match mic/line level and gain. Dante needs destinations able to receive that audio and a network configured for the selected mode. Wireless Workbench control does not replace the audio path. Choose by the actual equipment and inputs, not the connector alone.
At rehearsal, test one voice at a time and check its room and recording destinations. If tracks intended to be separate receive the same mix, compare Audio Summing and patch first; do not sum duplicate feeds again. Record the final map without changing a system in use.
Tell us the date, venue, simultaneous speakers, existing microphones/transmitters and recording deliverables. We can assess rental, purchase, an alternative configuration or assistance with system preparation, configuration and operation. Mark band, model or running order as undecided when needed. GLMedia can review the request; unit, compatibility, accessories, availability and terms are confirmed in the proposal.
Prepare the system
- Save receiver configuration and document transmitter models/bands.
- Coordinate legal frequencies and match the supported tuning range.
- Protect destinations before testing one channel.
Questions and troubleshooting
A transmitter fails to sync or RF appears without usable audio.
An RF indication alone does not confirm a valid audio link.
- Use the exact mixed-band compatibility tables when applicable; perform IR sync to the selected receiver channel and confirm success. Check encryption/sync warnings and transmitter mute.
- Compare receiver audio with the intended output. If incompatible or still silent, record bands, versions and messages for support rather than disabling security.
Two console inputs unexpectedly carry the same mix.
Inspect receiver Audio Summing before repatching the console.
- Read DEVICE UTILITIES > AUDIO SUMMING. Its selected groups affect XLR and Dante; Frequency Diversity is a different function.
- If isolated channels are intended, plan a protected change to OFF and verify each channel separately. Preserve an intentional summed design; do not sum again downstream blindly.
Receiver audio meters, but Dante or console control fails.
Audio transport and remote control need separate evidence.
- Match SWITCHED, REDUNDANT AUDIO or SPLIT to the official port map. Check subscription and clock for audio; application/interface and Yamaha Device ID for compatible console control.
- Do not change mode during a show. The manual requires removing network connections and a restart when changing it. If unresolved, preserve event logs, topology and versions for support.
Choose the next check
| Observation | Next check | What to record |
|---|---|---|
| No usable wireless audio | Band/IR/mute | Sync result and audio meter |
| Duplicated mix | Audio Summing | Group and destination |
| Network failure | Mode/clock/control | Logs and exact versions |
Precautions
- Keep redundant networks separate.
- Match XLR mic/line level to the console input.
- No generic factory reset, firmware update or copied IP plan.

Case 19: four voices and a defined RF system
For four panel voices, list every transmitter, regional band, capsule/microphone and receiver channel. ULXD4Q provides four receiving channels; it does not mean four transmitters, batteries and antennas are included. Validate the band for the venue and each unit.
Map antenna A/B paths, coax, distribution and power. The guide permits RF cascade to one additional receiver in the same band; do not extrapolate an unlimited chain or choose coax by BNC shape alone. Identify active/passive antennas and their documented power requirements.
Compare wired microphones for a fixed panel, a prepared wireless system or a mixed setup. Start with date, venue, simultaneous voices and approximate movement. Scope equipment, RF coordination, antennas, room/remote patch and operation separately. Rehearse actual positions: four catalog channels do not prove venue coverage.
More setup questions
Does a ULXD4Q receiver alone provide four microphones?
It requires compatible transmitters, microphones/accessories, power, antennas and output paths. Confirm the whole system for the band and venue before finalizing the proposal.
