MODEL: U-8, 8*32 Channels Wireless Conference Microphone(ACT / IR )

FEATURE :

*use UHF 500-980MHz  range ,adopt PLL combined technology ,and the transmitter power is adjustable ,they can be used several sets at the same time without interference  .

*CPU control with LCD display makes operation easy and performance outstanding .

*Use multi-channel with high frequency to avoid the interference .

*With audio compressing-expanding technology ,the machine can reduce the noises and increase the dynamic range .

*with ACT / IR function

*Having backsound restrain function can avoid backsound scream

*The receiver adopt multi-level high frequency enlargement .so and has the high sensitivity .

*Multi-level noise supervisory circuit .Special with the tone locked system make the machine have a strong anti-jamming characteristics .

*Using the best parts and CPU ,to keep the products with the perfect performance .

*100 meters in best condition ,60 meters in normal condition .The largest using range is above 100 meters in the spacious place ,50 meters for the ideal using range .
