Pure sound: the super-cardioid capsule captures more of what you want while rejecting off-axis noise. This makes the mic very resistant to feedback as well as a great choice for those working with loud stage volume levels. The included soundcheck mode on the receiver makes it possible to check the RF signal strength and audio levels continuously. The new G3 sync function allows you to wirelessly link the transmitter with the receiver with a simple push of a button. Lastly, the true diversity receiver has a built-in 5 band equalizer which completes this professional sound package.
