| 모델명 | WLM-B1 |
▶ With one-key automatic frequency search function, one-key lock button function
▶ Pure copper large ring cow power supply is more stable and safer
▶ 200 groups of selectable frequency points, can be used by 100 units at the same time, universal hand, strong anti-interference ability
▶ Using antenna diversity reception technology, the signal is more stable
▶ The audio is processed by new
tube technology, so that the low frequency is full, the midrange is
prominent, and the high frequency
is delicate and clear
▶ The receiver display shows the battery level of the transmitter
▶ Microphone body sensing, automatic mute, intelligent wake-up, energy saving and power saving
▶ Suitable for entertainment KTV, multi-function hall, home theater, small and medium-sized performance occasions
