One to two wireless microphones\"\"<\/span><\/h2>\n
\r\nFunction parameter \u25cfAdopt the world's advanced DPLL digital phase-locked loop multi-channel frequency synthesis technology and automatic noise control technology (with pilot). \u25cfUse UHF740MHz~790MHz frequency band to avoid interference frequency. \u25cfNew energy-saving mode settings, fully automatic EQ control function, automatic correction of tone, fully automatic automatic switch mode, automatic infrared frequency binding system, fully automatic scanning. \u25cfDual microphone design, two people can sing at the same time with hand-held microphone and invisible antenna. \u25cfAdopt true diversity receiving circuit design to ensure continuous speed within the effective distance and eliminate dead spots. \u25cfAdopt the latest high-frequency surface acoustic filter to filter out-of-band interference signals to the greatest extent. \u25cfUsing secondary frequency conversion high-frequency circuit design, it has extremely high sensitivity. \u25cfThe voice compression and expansion circuit greatly improves the signal-to-noise ratio. The unique voice compressor design prevents singers from cracking sounds even when they sing hard. \u25cfThe use of high-gain antennas effectively opens up the usable distance up to 100 meters. Complete input and output interfaces make it easy to connect various devices. \u25cfAny microphone in this system can be paired with any receiver, which completely solves the shortcomings of fixed frequency microphones and is suitable for multiple sets of products to be used on the same occasion. \u25cfOptional according to requirements: lavalier microphone TDWJ1 or head-worn microphone TDWJ2.\r\n<\/span><\/pre>\n
