A comprehensive first step into professional wireless, Performance Gear Wireless Systems are engineered to the same uncompromising quality standards as PGX, SLX, ULX and UHF-R wireless. Marrying superior sound quality and stage-proven endurance with advanced features like Internal Antenna Diversity and electable frequencies and variable companding, Performance Gear Wireless fulfils the promise of independent, confident performance through freedom from the wire. The wireless system shall operate in the UHF band between 536 MHz and 865 MHz, with the specific available frequency range being dependent on the users locale. Effective range of the system, receiver to transmitter, shall be 75 meters (250 ft.), under optimal conditions. Each system shall allow selection of over 10 operating frequencies across 12 MHz of bandwidth in order to avoid RF interference. Optimal frequencies shall be selected, ensuring that individual systems run at their highest level of performance, and that multiple systems in simultaneous use do not interfere with one another. Each transmitter shall be powered by one 9V batteries. Transmitters shall have a power onoff/mute switch, as well as multi-function LED indicator showing locked/unlocked status, mute status, and battery strength. Available transmitters shall include a bodypack for use with guitars, basses, and other instruments, as well as lavalier, headset or instrument microphones, and a handheld transmitter for vocals. The bodypack shall include a 3position switch and the handheld transmitter shall include a 2position switch to compensate for higheror lower-gain devices. Both transmitters shall feature an easily accessible channel selection button for system synchronization. The receiver shall have a channel display LED. The system shall use diversity variable companding technology to improve reception, minimize signal dropouts, and achieve the best possible signal-to-noise ratio, and shall include an audio level meter. The system shall be the Shure Performance Gear Wireless.
