UW - 2881 type diversity reception professional performance

True diversity design infrared automatic frequency channel 2 wireless microphones, receiving distance of 150 meters, the built-in four receiving circuit, any a microphone, there are two receiving circuit for receiving at the same time, with less noise interference of UHF frequency band PLL phase locking technology. Microcomputer CPU control, secondary frequency conversion technology, sound reduction degree is high, hand-held metal drop excellent results. 200 channels to choose from, regardless of the channel, it is more convenient to use. Suitable for high-grade professional stage singing, speech, conference, install and use the club.
