Sennheiser XS SK20 Transmitter
The wireless body-pack standard gets even better. Sennheiser has packed many useful features in the 158g weight of the SK20. The SK20 has an easy-to-read graphic display, 2.4Ghz sync, cable emulation, RF mute, an intuitive menu and much more. As features alone are no substitute for audio quality, the AF frequency response was expanded to 25-18,000 Hz for the truest sound.
