The UX professional wireless systems are built to last. 16 channels offer the freedom of running multiple systems simultaneously - no more buying one frequency systems that you have to specify each frequency. Rack mount one or two UX systems together with the optional UX-DR rack mount chassis. The UX-MC hand held system utilizes our finest CM68 element for crisp hi-end with a smooth bottom-end. Our latest dual AA batteries technology replaces the old 9V battery system lasting up to 25 hours without changing. The PLL (phase lock loop) engineering uses UHF technology (ultra high frequencies) to assure the signal carrier is locked-in for up to 300'. Dual Diversity receivers automatically switch to the best signal path so you don't get drop-outs - Full band width with less than .5% THD delivers impeccable sound that even the high priced systems lack - Step up to UX wireless so you'll never have to buy another system - this is your last stop for your wireless needs!
