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. Does it have handling noise?

A: The Samson Concert 288 SWC288HQ6 Dual-Handheld 16-Channel True Diversity Wireless System has a low signal to noise ratio of 85 dB. With normal use, handling noise for the handheld transmitters should be minimal or not noticeable.

Q: 2. Can this system expand to 16 microphones?

A: Yes, however: The receiver on this system is a single channel receiver (just like one radio receiver, it will only be able to "tune" into one radio station). This system accommodes/includes 16 channels that are available, individually to a single transmitter, choosing one of the 16 channels available on the receiver.. If 16 microphones are needed (0r any number from 2 up to 16), an additional system (another microphone with another transmitter) may be used in the same area.

Q: 3. can you replace the heards on these transmitters with Beata 58 heads?

A: You cannot change the capsule on the Shure BLX288/PG58. But you can buy the Shure BLX24R/B58 which comes with a Beta 58A Capsule. This is the B&H part number BH #SHB24RB58H10

Q: 4. Can you use rechargeable batteries

A: Yes AA rechargeable, listed under accessories: https://www.bhphotovideo.com/c/product/1194978-REG/shure_blx288_pg58_h10_blx288_dual_transmitter_handheld_wireless.html/accessories

Q: 5. Where it is made?

A: China

Q: 6. 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: 7. I see that the mics are powered by AA batteries. What about the receiver? Can the receiver run off of battery power, or does it have to be powered by an outlet?

A: Hello, Thank you for contacting Samson Technologies. The receiver for this system runs off of a power supply that can connect into a wall outlet. This power supply is included within the unit. If you have any other questions or inquiries, please let me know at any time. Best Regards, James

Q: 8. Is the base unit rack mountable?

A: No, the BLX88 receiver is not rack-mountable. To install it inside a rack, it would have to be on a shelf such as BH #SHURT2.

Q: 9. Are there external antennas?

A: Only on the belt pack. The receiver and handheld mic have internal antennae.

Q: 10. does this system include a case for protection and transport?

A: No, it does not.
