Part of the ULX-D wireless series, the Shure ULXD4D houses 2 independent digital receivers in a rugged, single-rack unit with an internal power supply. This GV version of the receiver features always-on AES-256 encryption and is designed for government and high-level executive applications where sensitive audio information may be transmitted. Two Ethernet ports support Dante digital audio, while RF cascade ports allow for antenna signal distribution to another receiver unit. Audio summing enables the receiver to function as a 2-channel mixer.

The ULX-D Series simplifies the set up and management of large numbers of wireless systems. It is ideal for professional sound reinforcement applications in large live venues and houses of worship as well as A/V installations in conference, educational, and corporate facilities. Compatible with a wide selection of Shure transmitters and mic capsules, it delivers pristine 24-bit/48 kHz digital audio, capturing every detail with clarity, accurate low end, and crisp transient response.

The ULX-D operates in the UHF band, utilizing Digital Predictive Switching Diversity to protect the transmission from interference, delivering rock-solid RF signal stability without audio artifacts. In Standard mode you can run up to 17 channels per 6 MHz TV channel, at a range up to 330'. Alternatively, the High-Density mode lets you run up to 47 channels per 6 MHz TV channel, at a maximum range of 98'. The system offers AES-256 encryption for security.

Each receiver module has its own audio and RF meters, 60 dB of gain control, and XLR output. A large LCD screen and intuitive controls let you quickly make adjustments, even in low-light situations. Additional features include automatic frequency scanning, IR sync, gain optimization to match any input source, and internal limiting to prevent clipping.

The Ethernet ports also allow multiple receivers to be easily networked together for simplified frequency coordination and deployment via Shure's Wireless Workbench software. In addition, the Channels Mobile App enables you to control the system remotely from an iOS device.

Related Questions and Answers

Q: 1. Does the URX-P41D provide a stereo digital Mi connection with a FX30 camera when used in conjunction with the SMAD-P30 adaptor?

A: Yes, the Sony URX-P41D Dual-Channel Camera-Mount Wireless Receiver can send stereo audio into the MI shoe of a Sony camera, but the adapter you would need is the SMAD-P5.

Q: 2. Is it compatible with other brands using the same frequency ranges?

A: No. This receiver only works with Saramonic UwMic9 system wireless transmitters.

Q: 3. Does this unit require an antenna management system?

A: No, in fact if you notice each of the antennas has an output just below the inputs. This unit basically behaves like an antenna distribution system.

Q: 4. Compatible with UwMic9?

A: Yes it is.

Q: 5. Will the balanced output drive a device that requires line level input? I was thinking of connecting it directly to the line level input of the Radial EXO-POD.

A: The Sony URX-P41D Dual-Channel Camera-Mount Wireless Receiver is only capable of Mic level output signals and does not offer Line level output.

Q: 6. How do I output two separate channels on this receiver? I see it only includes one 1/8" TRS to XLR cable.

A: The UwMic9-RX9 Dual Channel Camera Mount Receiver outputs a stereo signal which has both channels in one TRS 3.5mm cable. You can also use a stereo 3.5mm to dual XLR cable like B&H # HOHMX003Y or an equivalent 'Y' interconnect.

Q: 7. Would I be getting what is shown in the photo? The all black 2020 device or the old original yellow device?

A: This listing is for the Saramonic UwMic9-RX9, the old orange version. The new version is called the UwMic9S (BH #SAUWMIC9SK2M).

Q: 8. How many of the Shure BLXR receivers can be on at the same time? Not per band, in total.

A: Hi Angelo. With all wireless systems this largely depends on location and your surrounding RF environment. I'd suggest you contact Shure Applications Engineering at (847) 600-8440 to discuss your situation in more detail.

Q: 9. If utilizing this receiver with a Sony FX-3 and the SMAD-P5 and using two transmitters, is the system still true diversity? Also, is auto gain control the only option with the SMAD-P5 and the FX-3?

A: Yes, the Sony URX-P41D Dual-Channel Camera-Mount Wireless Receiver still uses true diversity reception when receiving audio from two transmitters and connected to the Sony SMAD-P5 Digital MI Shoe Adapter.

Q: 10. Does a 1080p 120hz input, output on the screen as 120hz or 60hz?

A: The Pioneer VSX-534 5.2-Channel A/V Receiver BH #PIVSX534 would display at 60Hz.
