The Shure SLXD4D is a dual-channel digital wireless receiver compatible with all SLX-D transmitters and housed in a rugged single-rack chassis with two removable antennas. It is ideally suited for rackmounting in portable flight cases and long-term installations for small- to medium-sized venues, event spaces, conference rooms, houses of worship, and education facilities.

The system 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 SLXD4D receiver offers intuitive LCD interfaces with meters for RF and audio output. It also offers 60 dB of gain control, and both mic/line XLR and 1/4" instrument outputs for each channel. 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.

• 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 H55: 514 to 558 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.

• 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.

• 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.

Related Questions and Answers

Q: 1. Where it is made?

A: China

Q: 2. Does it come with rack mount hardware?

A: Yes, rack mount hardware is included for the receiver.

Q: 3. Will this system work within a studio setting? Will the signal travel through a block wall?

A: You can use the Shure SLXD24D/SM58 Dual-Channel Digital Wireless Handheld Microphone System in a studio setting if you keep the receiver in the same room as the transmitters and run a longer cable from the receiver output to the inputs on the mixer. The signal will not transmit through cinder block walls.

Q: 4. Does this pair with any gooseneck mic system from Shure ?

A: The Shure SLXD24D/SM58 only works with other Shure SLX-D components. There are no Shure wireless SLX-D gooseneck systems.

Q: 5. How much handling noise does this microphone have?

A: Almost zero - barely detectable in most circumstances.

Q: 6. Is the FCC changing the frequency use for these mics?

A: Hi Rene, these wireless packages (BLX288/PG58) operate in bands below the portion being restricted by the FCC over the next couple of years. Specifically, the new restrictions cover frequencies above 608MHz; these Shure systems operate below that range. I've operated with this system (J10 band) for nearly a year now with no issues.

Q: 7. 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: 8. Can the receiver connect to my mirrorless camera or computer to livestream a presentation?

A: Yes, you will just need to connect the Shure BLX88 Receiver to the camera's audio input or to an audio interface like B&H # FOSSOLO4G to allow for livestreaming.

Q: 9. Can you take this audio into a cell phone or tablet?

A: You would need a compatible audio interface for the phone or tablet like the iRig Pro Duo BH #IKIRIGPRODUO.

Q: 10. Will the receiver transmit static when the mic is off?

A: The Shure BLX4 receiver in the Shure BLX24/PG58 Wireless Handheld Microphone System with PG58 Capsule should not, in theory, create any noise when not paired with the PG58 transmitter. However, this is not a specification that manufacturers provide for their wireless products. Because this system operates on open frequencies, the receiver could be susceptible to RF activity in the area, which could manifest itself as audible static noise.
