This is top of the line UHF wireless microphone ! Super clear, the back ground noise is limited to a level that you can hardly hear anything through your clean sound system, the operation range is very large, up to 500 feet when I tested.  A new technology we use to display the channels and frequencies. You can change the channel or frequency easily by press UP/Down button. From channel 1 to channel 16 or you can change the frequency to match any wireless microphone you have before.

On the hand held microphone, you can dial the channel selector to choose the channel to match the receiver.

A great microphone that we ever made !
