Product performance:
 ●This product adopts UHF 4-channel design, which allows the use of 4 handheld or 4 lavalier wireless microphones at the same time without interference.
 ●With noise lock and pilot frequency function, it can solve the noise and cross-frequency interference problems that are difficult to overcome for general wireless receivers.
 ●The ideal distance is more than 60 meters, and 40 meters in complex environment.
 ●Use 10 sets at the same time in the same event (40 microphones)
 ●Beautiful tone, extremely penetrating treble, full and soft midrange, and deep low-frequency potential.
