Shure SLXD2/B87A Digital Wireless Handheld Microphone Transmitter with Beta 87A Capsule

The Shure SLXD2/B87A=-G58 is a handheld microphone transmitter that brings clear, dependable digital wireless audio to singers, presenters, and sound engineers. It marries Shure’s SLX-D transmission platform with the respected Beta 87A supercardioid condenser capsule, capturing voices with studio-level detail while keeping background noise and feedback at bay.

The transmitter delivers 24-bit audio across a 44 MHz UHF tuning range, giving crews the flexibility to find open frequencies even in RF-dense environments. A selectable RF output of 1 mW or 10 mW lets you balance battery life with transmission strength, and the signal remains stable at distances up to 330 feet in line-of-sight conditions.

Daily operation is straightforward. An infrared sync function pairs the transmitter with a compatible SLX-D receiver in seconds, so setup time stays short even when schedules are tight. Two standard AA batteries power the unit for up to eight hours, and you can switch to the optional SB903 rechargeable pack for a more sustainable workflow without changing your routine.

Its lightweight aluminum housing is easy to hold yet tough enough for life on the road, whether you are working a corporate conference, a worship service, a small club, or a busy rental inventory. If your needs evolve, the Beta 87A capsule can be swapped for other Shure options such as the SM58 or the KSM8, giving you long-term versatility from the same transmitter body.
