UW-8240  (4 in 1)

This series product as infra-red automatic matching frequency 4 channel wireless microphone. It adopted the UHF frequency PLL phase locking technology of little noise interference. It adopted microcomputer CPU control, two times frequency conversion technology. High sound reduction,400 channel can be selected, not divided A、B、C、D channel, more convenient for using .Full metal material standard case,1U metal panel respectively allocated with 4 channel receivers, the installment with big liquid crystal display. The host is respectively provide 4 channel balance audio output socket and mixing unbalance output ,in accordance with every kind of connection requirement It suitable for high level speech, conference, club allocated using.
