A powerful companion on every stage setting or outdoor application: this lightweight digital bodypack transmitter ensures a reliable sound transmission even under the toughest conditions. The SK 9000 is compatible with 3-Pin lemo connector for lavalier microphones and instruments with an optional adapter cable.

The housing of the SK 9000 is made of die cast magnesium to offer maximum robustness at a very low weight. Ease of use and safety against unwanted changes were the criteria for the design of the user interface. This is achieved by the icon-based menu structure and infrared synchronization with the receiver. Exchangeable energy packs with environment-friendly Lithium Ion technology supply the required energy while saving thousands of batteries over time.
