The SKM100-845 G3 raises the bar with its integral sync function. The transmitter automatically adjusts to a corresponding G3 receiver with a simple push of the receiver's sync button. The capsule provides rich sound while minimizing the risk of feedback. The directivity of the microphone reproduces the voice clearly while rejecting ambient background noise; this makes it a great choice where feedback may be an issue. Perhaps you want a different pick-up pattern or sound characteristic? The G3 microphone heads can be changed out in seconds without tools.
