Shure AD2/B58 Digital Handheld Wireless Microphone Transmitter with Beta 58A Capsule (G57: 470 to 616 MHz)

The Shure AD2/B58=-G57 is a handheld digital wireless microphone transmitter built for Axient Digital systems and fitted with the renowned Beta 58A vocal capsule. It delivers a dependable, studio-quality signal that lets singers, presenters, and engineers focus on the performance rather than the gear.

The dynamic capsule uses a supercardioid polar pattern that isolates the voice and minimizes stage spill, giving more gain before feedback in loud environments. Digital transmission within the 470 to 616 MHz UHF band maintains clarity, while AES 256-bit encryption keeps the audio feed secure. Selectable RF output at 2, 10, or 35 mW adapts to everything from club stages to stadium tours, and a line-of-sight range of up to 330 feet helps ensure dropout-free coverage.

Power management is straightforward: two AA batteries provide about eight hours of runtime, or switch to an SB900A rechargeable pack for roughly nine hours and convenient recharging. Infrared sync pairs the transmitter with an Axient Digital receiver in seconds, and automatic gain adjustment sets levels on the fly. Because the capsule mount follows Shure’s interchangeable standard, you can swap heads to match different vocal styles or venue needs. These features make the AD2/B58=-G57 a solid choice for touring acts, houses of worship, corporate AV teams, and anyone who cannot afford wireless failure.
