1 drag 8  Wireless Microphone DL-880

Functional features:

● UHF ultra-high frequency band, less interference than the traditional VHF frequency band, more reliable transmission;

●PLL digital phase-locked loop multi-channel frequency synthesis technology, in the 50MHz frequency range, at 250KHz channel interval, provide up to 200 channel choices, convenient for multiple machines to use at the same time, easily avoid all kinds of interference;

● Advanced automatic frequency control technology, even if the transmitter and receiver frequency is messed up, just click, the transmitter will automatically lock the frequency and adjust the same, easy to use;

● High-grade LCD screen, so that the receiver and transmitter working state at a glance;

● Wireless conference launching system, using two AA batteries, using high alkaline battery can be used for a long time (high power 10 hours, low power 14 hours). If you use rechargeable batteries, the service time will be reduced.

● The widest use range is more than 100 meters, and the ideal use range is 60 meters.

● Conference transmitter with mute function

● Digital ID identification technology to ensure that communication does not interfere with each other

● Unique digital encryption technology, there is no longer off-site monitoring or eavesdropping trouble
