The Shure SLXD4 Digital Wireless Receiver is a single-channel digital wireless receiver housed in a rugged, metal half-rack chassis with two removable antennas and compatible with the SLX-D Series transmitters. It is ideally suited for rackmounting in portable flight cases or long-term installations for small- to medium-sized venues, event spaces, conference rooms, houses of worship, and education facilities.
The SLXD4 delivers crystal-clear, 24-bit digital audio with a wide dynamic range for natural vocal reproduction to presenters, vocalists, clergy, lecturers, and performers. It operates in the UHF band and uses Digital Predictive Switching Diversity technology to protect the transmission from interference and deliver a solid, reliable RF signal without dropouts.
The all-metal, rackmount SLXD4 receiver features an intuitive LCD interface with metres for RF, battery status, and audio output. It also offers 60 dB of gain control, and both mic/line XLR and 1/4" instrument outputs. Additional features include automatic frequency scanning and IR sync to easily link the transmitter and receiver to the same frequency.
You can run up to 32 mics simultaneously in the same space. Setting up multiple systems is made quick and easy via the Ethernet port which allows you to execute a coordinated frequency scan for all the connected receivers from a single location.
Transparent Digital Sound, Dependable Performance, and More Mics
- The SLXD4 receiver is compatible with the SLXD1 bodypack and SLXD2 handheld transmitters.
- The system offers 24-bit digital audio with a fast transient response and over 120 dB of dynamic range—resulting in clear, accurate sound.
- 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.
- 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, half-rack metal chassis with detachable antennas, the SLXD4 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 metres 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.
