The Shure SLXD2/B87A is a digital handheld wireless microphone transmitter compatible with SLX-D receivers. It comes equipped with the Beta 87A supercardioid condenser capsule designed to withstand extreme sound pressure levels, while still delivering a remarkably smooth frequency response for vocal performers and presenters. The capsule features a supercardioid polar pattern that offers excellent rejection of off-axis background noise, helping to reduce feedback.
The system operates on a 46 MHz UHF tuning range with 1840 frequencies available. The 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 a rechargeable SB903 battery pack (available separately).
The SLXD2/B87A handheld transmitter delivers crystal-clear, 24-bit digital audio quality and reliable RF performance in a lightweight, yet durable aluminum housing. It is well suited for use in small- to medium-sized venues and houses of worship or with A/V installations in a conference, educational, or corporate facilities.
Clear, Accurate Audio with Interchangeable Capsule
The unit delivers clear, reliable 24-bit digital audio.
The Beta 87A supercardioid condenser capsule handles SPL levels up to 140 dB and offers a smooth frequency response with a gradual presence rise and controlled proximity effect tailored for vocals.
The interchangeable capsule design allows you to replace the Beta 87A capsule with a Shure capsule that’s ideal for your application and simply screw it onto the transmitter—including the SM58, KSM8, and Beta 58A capsules.
User-Friendly Features in a Rugged Housing
The unit quickly syncs with a wireless receiver via infrared at the touch of a button.
An easy-to-read LCD shows important information
1/10mW selectable RF output power allows you to increase either the transmitter's range or the number of mics operating simultaneously.
Convenient Power Management Options
Operates for up to 8 hours on two AA batteries.
The optional SB903 lithium-ion rechargeable battery offers convenient power management with zero memory effect and precision metering in hours and minutes on the transmitter's LCD screen.
The SBC203 dual-battery station charges two SB903 batteries at once—it fits the external contacts on the transmitter so you don't have to remove the batteries to recharge.
