| Product Name：PWM-U20 Series Wireless Microphone |
Product Description：
The technical investigation and innovative design of H-WIT makes it possible to have the best wireless microphone system which brings us perfect sound performance with high quality and hyper-stability.
Special impulse suppression circuit totally removes the noise when you switch on/off the microphone.
Wide range of dynamic, sound naturally reproduction, makes the speech easier and smoother.
Good sound code locking capacity, stable receiving and long distance pick-up.
The receiving circuit chooses stable double-tuning diversity design to avoid staccato phenomenon. Gain aerial greatly improves the receiving result.Excellent S/N( above 80dB) gives you fresh, pure sounds. The bottom ON/OFF design can avoid unexpected accidents.
