The Shure SLXD15/UL4B offers videographers, journalists, documentary makers, and content producers a reliable wireless lavalier microphone system that delivers crystal-clear digital sound quality while also being quick and easy to set up, even if you're using multiple mics on set. Built around a rugged, single-channel receiver that can be camera-mounted or used in an audio bag, the system offers a comprehensive feature set that ensures professional-sounding, broadcast-ready results for demanding filmmakers and creators. This configuration includes a bodypack transmitter and a black UL4 UniPlex cardioid lavalier microphone.

• The SLX-D delivers 24-bit digital audio with a fast transient response, a 20 Hz to 20 kHz frequency response, and a 118 dB dynamic range, resulting in clear, accurate sound.
• Operating far away from potential Wi-Fi interference in the 2.4 GHz band, this configuration of the system transmits in the H55: 514 to 558 MHz UHF band, with a 44 MHz tuning range and 1760 frequencies it can autoscan to ensure a clean wireless signal.
• Digital Predictive Switching Diversity uses a microprocessor to switch between the two antennas before dropouts occur.
• A low latency of 3.2 ms helps ensure your sound and picture are easy to properly sync.
• The SLX-D's spectrum-efficient digital transmission technology allows for up to 32 mics to be used at once.
• Great for shoots with several cameras and microphones, Multi-Mic Mode lets you scan and create a list of clean frequencies, which you can send to multiple receivers via IR.
• Each receiver will sync to the appropriate transmitter at the touch of a button; settings on the transmitters like the input gain and high-pass filter are also recalled.
• Multi-Mic Mode makes channel allocation easier and more efficient since the receivers aren’t all auto-scanning and competing for open frequencies.

• This configuration comes with a subminiature UL4 UniPlex lavalier microphone optimized for speech intelligibility and equipped with a cardioid polar pattern that helps to reject unwanted noise.
• The advanced 1.6mm Shure Plex cable lasts longer than competing cables due to a dual redundant ground, which doubles as a secondary shield. It also offers virtually zero memory effect, won’t kink, and is fully paintable. 
• The lavalier mic plugs securely into the locking TA4M connector on the compact and discreet 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.
• The mic offset function provides up to +21 dB of gain to boost low-volume speech and ensure multiple microphones are at similar levels.
• Engage the 150 Hz high-pass filter to reduce distracting, unwanted low-end for clearer speech.
• A selectable 1/10mW RF output allows you to increase the transmission power to overcome interference, if necessary, and the system provides a transmission range up to 330'.
• Two AA batteries or an SB903 rechargeable battery (available separately) will power the unit for up to 8 hours.

• Powerful and portable, the SLXD5 is a single-channel digital wireless receiver for on-camera cold shoe mounting and audio bag use, featuring user-configurable front-panel controls and a bright OLED screen for key system function readouts and remaining battery life.
• Housed in a tough metal chassis with adjustable front-mounted antennas, the SLXD5 is a great fit for on-the-go shooting rigs.
• It offers adjustable gain control and dual 3.5mm outputs including a headphone monitor out and switchable line/mic output. Additional features include automatic frequency scanning and IR sync to easily link the transmitter and receiver to the same frequency.
• Two AA batteries or an SB903 rechargeable battery (available separately) will power the unit for up to 5.5 hours.
• The receiver’s USB-C port can be used to recharge the SB903 battery or power the unit.

• Adding the SB903 lithium-ion rechargeable battery, along with an SBC10-903 single charger, SBC203 dual-docking charger, or SBC80-903 8-bay charger offers a cost-effective and environmentally friendly alternative to throwing away AA batteries (batteries 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 or receiver.
• When powered by an SB903, the transmitter and receiver both display the remaining battery life in hours and minutes.
• For bag use, the SBC-DC-903 battery eliminator (available separately) allows you to power the receiver from your mixer's battery.

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

• The WL183 omnidirectional lavalier mic offers consistent pickup, even when the talent turns away from the mic.
• The WL184 supercardioid lavalier mic offers a very narrow, feedback-resistant pickup pattern for louder events where sound reinforcement gear is used.
• If you need a waterproof option, the DL4 DuraPlex miniature lavalier features an IP57 rating for water and dust resistance. Its forgiving omnidirectional microphone capsule delivers a clear, transparent, full-range sound.
• The SLXD2 handheld transmitter is available with several mic capsules choices for presenters who prefer the flexibility of a handheld microphone.
• Add the XLR microphone of your choice to the system with the SLXD3, a plug-on transmitter with a secure locking connector that features both 12 and 48V phantom power for condenser mics.
