PANASONIC / WX-4700

Variations

In addition to two wired microphones, you can connect two inputs, such as a boombox or CD player, for a total of four inputs. These sources can be transmitted to an 800MHz wireless receiver. Amplification is possible using existing wireless equipment, minimizing cable runs. It also has a built-in ""auto-mute function"" that detects audio input to Mac Input 1 and automatically lowers the volume of other inputs. This wireless transmitter is small and lightweight, making it easy to set up and take down.
