Sennheiser packs many useful features into the 158g weight of the SK 100 G3 compact bodypack transmitter. The SK 100 G3 wireless transmitter has an easy-to-read graphic display, infrared sync, charging contacts, cable emulation, RF mute, an intuitive menu, and much more. As features alone are no substitute for audio quality, the Sennheiser SK 100 G3 transmitter's AF frequency response was expanded to 25-18,000Hz for the truest sound.
