The Shure SLXD14/DL4B offers actors, performers, instructors, clergy, and presenters a wireless lavalier microphone system that's easy to set up and dependable, which delivers crystal-clear digital sound quality. Built around a rugged, single-channel, half-rack receiver with removable antennas, the system is ideally suited for portable rigs or long-term installations in small- to medium-sized venues, event spaces, conference rooms, houses of worship, and education facilities.

The SLX-D operates in the UHF band to transmit high-quality, 24-bit digital audio with over 120 dB of dynamic range for crisp, detailed sound. It utilizes Digital Predictive Switching Diversity to protect the transmission from interference and deliver a solid, reliable RF signal without dropouts.

This configuration comes with a black DL4 DuraPlex waterproof miniature omnidirectional lavalier microphone built to withstand the rigors of professional use. The discreet bodypack transmitter has a selectable 1/10mW RF power output and a transmission range up to 330'. It provides up to 8 hours of operation on two AA batteries or an SB903 rechargeable battery (available separately).

The all-metal, rackmount SLXD4 receiver features an intuitive LCD interface with meters 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.

With up to 32 mic channels available at the same time, the SLX-D is ready to expand as your needs grow. What’s more, setting up multiple systems is made fast and easy via the Ethernet port, which links the receivers together for quick, coordinated frequency scans 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 J52: 558 to 602 + 614 to 616 MHz UHF band with a 46 MHz tuning range and 1840 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.
• With a low latency of 3.2 ms, the system is ideal for applications that require live sound reinforcement.
• The SLX-D's 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, 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, event, or performance.
• 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 the SB903 lithium-ion rechargeable battery, along with an SBC10-903 single charger or an SBC203 dual-docking charger, offers a cost-effective and environmentally friendly alternative to throwing away AA batteries (battery and chargers available separately).
• Using the SB903 battery and SBC203 charger simplifies the task of keeping multiple transmitters charged and ready—you can even recharge the battery while still in the transmitter.
• When powered by an SB903, the transmitter displays the remaining battery life in hours and minutes.

• 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.

Shure offers numerous lavalier, headset, and handheld microphone options to adapt your SLX-D system as your needs evolve.

• The WL185 (cardioid) and WL184 (supercardioid) lavalier mics offer narrower, feedback-resistant pickup patterns for louder events.
• The discrete MX153 sub-miniature earset mic provides exceptional clarity in spoken word applications.
• The SM35 is a comfortable, durable headset microphone for active performance.
• The SLXD2 handheld transmitter is available with several mic capsules choices for presenters who prefer the flexibility of a handheld microphone.

Related Questions and Answers

Q: 1. Are there external antennas?

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

Q: 2. Will this system be impacted by the recent re-allocation of portions of the the 600mhz frequency ranges to cell phone companies? Or is their use illegal?

A: The bandwidth referred to collectively as the 600 MHz band includes frequencies from 617 to 698 MHz. Since this product operates below this space, it will not be affected by the reallocation.

Q: 3. Can you use 3 of these units together? We need a total of 6 mics for a theater production.

A: Yes, technically you can use 3 of these systems together. The normal max channel count for BLX systems without frequency distribution is 6. Having little to no interference really depends on where you will be using this system. Please use Shure's Frequency Finder website to make sure you are purchasing the correct frequency band based off your area code. https://www.shure.com/en-US/support/tools/frequency-finder

Q: 4. Does this set work without a mixer?

A: The wireless mic system can be plugged directly into a powered speaker, via the MIC level XLR output or the LINE level 1/4-inch output.

Q: 5. Shure BLX 1288/CVL-J10 is this rack mountabled??

A: No it isn't. I used a 1U rack shelf and used command strips to secure it.

Q: 6. Is there a battery level indicator on the receiver or transmitters?

A: No there is not, but they hold a charge for a good amount of time 3+++ hours.And now I will check out this LED solution.

Q: 7. Are these Mics UHF?

A: Yes. These microphones are UHF operating at 584 - 608 MHz

Q: 8. Can both of the microphones work at the same time? Can you connect additional bodypack transmitters, and run all of them at the same time?

A: The Shure BLX188/CVL Dual-Channel is what is known as a dual channel system. You get 2 mic's but 1 receiver with 2 outputs. Yes you are supposed to use both mic's at the same time. That is the purpose of the system. You cannot expand on the system.

Q: 9. Can I buy several sets on two different bands for 12 mics all working at the same time a?

A: Yes you can use 3 systems of the Shure BLX188/CVL in one band and 3 in another band to be able to use 12 mics at the same time without their signals interfering.

Q: 10. Do these work with the paddle antennas to get more range or help with interference?

A: No, the Shure BLX88 receiver included with the Shure BLX188/CVL Dual-Channel Wireless Cardioid Lavalier Microphone System has built-in internal antennas and is not able to connect to external antennas. For this option, you will want to consider using the Shure BLX4R, SLX-D, QLX-D, and ULX-D series receivers.
