Part of the ULX-D wireless series, the Shure ULXD124D Dual-Channel Wireless System with BETA B58Ahouses 2 independent digital receivers in a rugged, single-rack unit with an internal power supply. 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 it include two wireless lapel microphones?

A: No, this listing is for the dual-channel receiver only. If you are looking to purchase a complete dual lavalier wireless system, I would recommend the BLX188/CVL. a href= http://www.shure.com/americas/products/wireless-systems/blx-wireless-systems target= _blank http://www.shure.com/americas/products/wireless-systems/blx-wireless-systems/a

Q: 2. Can I stack multiple of these units? Thanks!

A: Shure does not recommend stacking multiple BLX88 and BLX4 receivers on top of each other since the antennas are built into the casing. You may want to consider the BLX4R receivers instead since this model has external antennas and multiple receivers can be easily rackmounted and stacked on top of each other without blocking the signal from going to the antennas.

Q: 3. what wireless label microphones would work well with this receiver?

A: The Shure SM58 wireless microphones with H9: 512 - 542 MHZ work excellent with this receiver.

Q: 4. will this system work in a fitness studio? we have coaches who sweat and are active during a group fitness class

A: Yes, the Shure SLXD14D Dual-Channel Digital Wireless Bodypack System with No Mics will be able to function inside a fitness studio. Please be aware that you will need to add microphones to connect to the transmitters and that the antennas for the transmitters and receiver must be within line of sight of each other in order for the system to function properly.

Q: 5. it seems geared to I struments, the ta4m ports will fit a WL185, but will they work well with them?

A: Although the Shure SLXD14D Dual-Channel Digital Wireless Guitar System (G58: 470 to 514 MHz) BH #SHSLXD14DG5 is packaged for for two guitar or bass players, itmay be used wih Shure WL185 microphones as well.

Q: 6. Does the mic have a mute button? If not can you mute mics from the receiver?

A: There is no mute button on the transmitter or receiver of the Shure SLXD24D/B58 Dual-Channel Digital Wireless Handheld Microphone System with Beta 58 Capsules. Any muting would need to be done via the mixing desk.

Q: 7. I HAD THE BLX2 88 OLD MODEL WITH ANTENNAS,AND 2 SM58A MIC,I LIKE TO ADD ON BLX288/58, ARE THEY CAN BE WORK TOGETHER? THANKS, RICK.

A: Yes, you can use the Shure BLX288/B58 Dual-Channel Wireless Handheld Microphone System with Beta 58A Capsules and your older Shure BLX series wireless microphone system at the same time. It doesn't matter whether the two systems operate on different frequency bands or if they both are on the same band. Since the BLX series system has 123 individual frequencies within the band, up to 12 BLX series systems that operate on the same band can be used at the same time within a 300 foot range without any problems.

Q: 8. I have the Dual-Channel System with H55: 514 to 558 MHz band. I want to get a second unit. Should I buy the same frequency band?

A: In most cases you can use the same frequency band, but to be sure, please click the following link. The Shure Frequency Finder will show you how many microphones you can use per frequency band based on your zip code. https://www.shure.com/en-US/support/tools/frequency-finder

Q: 9. Will the receiver connect to my mirrorless camera or computer to live stream a presentation?

A: Yes, you just need to connect the Shure SLXD4D receiver to the camera's audio input or to an audio interface such as B&H # FOSSOLO4G to allow for use with livestreaming software.

Q: 10. Are these bodypacks compatible with MX153 earsets?
