The Shure SLXD14/SM35 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 utilizes 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 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 them together for quick, coordinated frequency scans from a single receiver.

• 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.

• Adding UA874 active antennas or PA805SWB passive antennas increases the range of your system and offers increased protection against interference.
