Shure GLXD2+/B58 Dual Band Handheld Transmitter

The BETA 58A features a dynamic capsule pneumatic shockmounted to resist handling noise, while the narrow supercardioid pickup pattern is maintained across the mic's frequency range, allowing it to consistently reject sound at its off-axis points and deliver high immunity to feedback—great for use on stage when sound reinforcement equipment is deployed. The mic offers a 50 Hz to 16 kHz frequency response, with a bass roll off and gently enhanced presence boost at approximately 3 kHz for added clarity. A hardened steel grille resists wear and abuse.

• GLX-D+ Dual-Band Digital Wireless systems operate in both the 2.4 and 5.8 GHz frequency ranges, automatically scanning both to select the one that offers the higher number of clean channels.
• The system offers true digital diversity, which means two antennas and two independent receiver modules work together to reduce RF signal dropouts.
• In addition, the GLX-D+ transmits on its own main frequency just like a traditional system, but it also transmits on 2 extra "backup frequencies" at the same time. If the system detects interference on the main frequency, it will switch to one of the backups automatically without the user even knowing.

• The GLXD2+ handheld transmitter runs on an intelligent SB904 rechargeable lithium-ion battery (included).
• The battery provides up to 12 hours of continuous use on a full charge.
• The SB904 battery can be recharged in the GLXDR4+ receiver's charging bay (located on the front panel). The charging bay can also be used to recharge a spare battery while the transmitter is in use.
• Alternately, the SB904 can be recharged while in the handheld transmitter with a USB charging cable.
• Just a 15-minute quick charge provides 1.5 hours of use.
• The SB904's remaining battery life is displayed in hours and minutes from the receiver's front panel.
