Product Description
Shure SLXD4D Dual-Channel Digital Wireless Receiver
The SLXD4D Dual Receiver is the convenient, streamlining choice for confident speech presentation and vocal performance from lecture halls to live entertainment.
SLX-D Digital Wireless delivers transparent, 24-bit digital audio and rock solid RF performance with easy setup and rechargeability options in a suite of versatile wireless system configurations. Featuring industry-leading digital wireless technology and design in a convenient dual, full-rack configuration, the SLXD4D saves space and accessories for any size of multi-system configuration A variety of interchangeable microphone choices guarantees the right solution for a wide range of applications, from day-long presentations to nighttime performances.
Transparent Digital Sound, Dependable Performance, and More Mics
- The SLX-D delivers 24-bit digital audio with a fast transient response and over 120 dB of dynamic range—resulting in clear, accurate sound.
- The system operates in the G58: 470 to 514 MHz MHz UHF band with a 44 MHz tuning range and 1760 selectable frequencies, far away from potential Wi-Fi interference in the 2.4 GHz band.
- Digital Predictive Switching Diversity uses a microprocessor to switch between the two antennas for the cleanest signal—before dropouts occur.
- Low latency makes the system ideal for applications that require live sound reinforcement.
- Spectrum-efficient digital transmission technology allows for up to 32 mics to be used at once.
- Up to 10 compatible systems per 6 MHz TV band and 12 systems per 8 MHz band are supported.
- Ethernet networking saves you time with coordinated group scanning between multiple receivers from a single location; TCPI command streams from third-party companies such as AMX and Crestron are also supported.
Ready to Rackmount, Easy to Use
- Housed in a tough, single-rack metal chassis with detachable antennas, the SLXD4D receiver is a great fit for A/V installations or as part of a portable rackmount rig—ready to travel to a meeting or event.
- The SLX-D is engineered to provide outstanding sound for small- to medium-sized spaces and facilities—without costly, complicated features required primarily for large venues.
- Intuitive front-panel controls and a high-contrast LCD screen with audio and RF meters makes set up a snap.
- The auto-scan function automatically seeks out the cleanest available frequency for you. The receiver and transmitter then easily link to the same frequency via infrared.
- The receiver offers up to 60 dB of adjustable gain, and the display shows you where the ideal level should be.
Enhance the Reliability of Your Receiver
- Adding UA874 active antennas or PA805SWB passive antennas increases the range of your system and offers increased protection against interference.
- The UA844+SWB antenna distribution system (available separately) lets you stretch the power of your antenna pairs, giving you more on-air channels in less setup time.
