BETA 87A Microphone for Stage-Ready Vocals
The BETA 87A features a condenser capsule engineered with a wide 50 Hz to 20 kHz frequency response and a controlled proximity effect to deliver crisp and detailed vocals for performances and presentations. The mic has been designed to resist handling noise, while the narrow supercardioid pickup pattern allows 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. A hardened steel grille resists wear and abuse.
Dependable Wireless Performance
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.
Intelligent Battery Rechargeability for Uninterrupted Performance
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.
