Shure GLXD2+/SM58 Dual Band Handheld Transmitter

Relied on by live engineers and singers worldwide, the rugged SM58 features a dynamic capsule that's pneumatically shockmounted to resist handling noise, while the cardioid polar pattern focuses audio capture on the vocalist, helping to reduce feedback issues when sound reinforcement equipment is used. Built into the SM58 is a pop filter, which helps control wind and breath noise without requiring an external pop screen. A steel-mesh grille protects from wear, abuse, and the challenging conditions of live events. The transmitter features an On/Off switch that can be locked out at the receiver to prevent accidents.

• 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.
