Features:

1.DPLL digital phase-locked loop frequency multi-channel synthesis technology, in 50MHz frequency bandwidth to 250kHz channel spacing provide up to 200 channel choice, convenient multiple sets of machines at the same time using easy to avoid all kinds of interference.

2. Advanced automatic frequency technology, even if the transmitter and receiver to the frequency of the chaos only need to gently press the transmitter will automatically follow the lock receive frequency and adjust the use of the same.

3 .High-end LCD screen, so that the receiver and transmitter work status at a glance.

4. Wireless microphone launch system, using two AA batteries. The high alkaline battery can be used for a long time (8 hours of high power, low power 12 hours) if the rechargeable batteries, the use of time will be decreased.
