The Shure SLXD2/B58A is a digital handheld wireless microphone transmitter compatible with SLX-D receivers. It comes equipped with a Beta 58A dynamic capsule designed for close-up vocals, with brightened midrange and bass roll-off to control proximity effect. The capsule features a supercardioid polar pattern that ensures high gain before feedback, maximum isolation from other sound sources, and minimum off-axis tone coloration.
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/B58A 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.
