Sennheiser SK 500 G3 606-648MHz Beltpack

More usable systems per range. As the pros have known for years, having the option of lowering a transmitter‘s RF output power helps immensely when simultaneously operating a large number of wireless systems. This transmitter also features wireless sync to link up to a compatible G3 receiver automatically with a push of a button. The revised backlit display provides a wealth of useful information at a glance, even on the darkest of stages.
