The Shure GLXD2/B58 is a digital wireless handheld microphone transmitter compatible with GLX-D Digital and GLX-D Advanced Digital Series 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.
GLX-D Digital systems operate anywhere in the world in the 2.4 GHz spectrum, well away from potential TV and radio interference. The transmitter's RF output is fixed at 10mW and offers a maximum transmission range of 165' outdoors and 200' indoors. The gain is adjusted remotely from the receiver in 1 dB steps at a range from -18 to +42 dB.
Shure's frequency management technology monitors interference and automatically switches to a clean channel if necessary, ensuring seamless, uninterrupted performances. The transmitter's LED indicates the link status and warns you when the battery is getting low.
The GLXD2/B58 is housed in a lightweight, plastic chassis and provides up to 16 hours of operation with the included SB902 rechargeable battery. The battery can be recharged inside the transmitter from the USB port, using the included USB charger cable, or removed from the transmitter and recharged in the GLXD4 receiver's charging bay. A 15-minute charge provides up to 1.5 hours of performance time.
