The Shure SLX-D-24D/B58 is a dual-channel digital wireless microphone system equipped with two Beta 58A handheld transmitters, delivering the renowned supercardioid capsule response across two independent channels. Operating in the H58 band, this rack-mountable system brings 24-bit digital clarity to vocal applications where two performers need simultaneous wireless access. The included SLX-D dual receiver manages both channels within a single rack space, making it a space-efficient choice for houses of worship, corporate presentations, and small to mid-sized live performance venues. Each Beta 58A capsule features a precision-engineered supercardioid polar pattern that provides maximum gain before feedback and superior off-axis rejection. The system operates across a 58 MHz tuning bandwidth within the 520-578 MHz range, with up to 32 compatible channels available per band. Digital predictive switching diversity ensures dropout-free reception, while the transmitters run on two AA batteries with up to 8 hours of operation. Both handheld units transmit with 10 mW output power, and the receiver offers balanced XLR and ¼" outputs per channel with adjustable gain control.
