Description
The Shure SLXD14/SM35 Digital Wireless Cardioid Performance Headset Microphone System offers instructors, presenters, clergy, and performers a wireless headset microphone system that’s dependable, easy to set up, and features 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 utilises Digital Predictive Switching Diversity to protect the transmission from interference and deliver a solid, reliable RF signal without dropouts.
This configuration comes with an SM35 cardioid performance headset microphone built for clear vocal reproduction. The headset’s wearable design offers a comfortable and secure fit for long-wearing use and gives active performers the freedom to move and express themselves without sacrificing sound quality. The bodypack transmitter features a selectable 1/10mW RF power output and a transmission range up to 100m. 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 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.
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 them together for quick, coordinated frequency scans from a single receiver.
Key Features:
Lightweight Bodypack Transmitter with Headset Mic for Hands-Free Presentations
- The SM35 condenser performance headset mic features a cardioid polar pattern that helps reject signal bleed and feedback for use on stages and behind floor monitors. The flexible gooseneck design with discrete adjustment options lets you position the microphone for further source isolation in loud environments.
- The headset mic plugs into the locking TA4M connector on the compact SLXD1 bodypack transmitter.
- The rugged, plastic transmitter has a belt clip that attaches to the talent’s clothing and an LCD that shows essential information.
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.
-
Digital Predictive Switching Diversity uses a microprocessor to switch between the two antennas before dropouts occur.
-
With a low latency of 3.2 ms, the system 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.
-
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.
Optional Rechargeable Battery Management
- 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 (batteries and charger 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.
Enhance the Reliability of Your System
- 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.
A Variety of Mics and Transmitters Available
Shure offers numerous lavalier, headset, and handheld microphone options to adapt your SLX-D system as your needs evolve.
- The discrete MX153 sub-miniature earset mic provides exceptional clarity in spoken word applications.
- The WL183 omnidirectional lavalier mic is a clip on mic that offers consistent pickup even when the talent turns away from the mic.
- The WL184 supercardioid lavalier mic offers a narrower, feedback-resistant pickup pattern for louder events.
- The SLXD2 handheld transmitter is available with several mic capsules choices for presenters who prefer the flexibility of a handheld microphone.
