The SK 9000 Bodypack Transmitter from Sennheiser is the perfect tool for achieving impeccable, reliable sound transmissions—no matter how difficult the conditions. With its intuitive user interface, the SK 9000 is effortless to set up and flexible to operate. Its lightweight, yet rugged, design makes it a great choice for applications that need consistent quality in a low-profile build, such as stages, studios, or even outdoor audio.
Using diecast magnesium, the SK 9000 is constructed to be lightweight while also durable enough to handle the rigors of live performance and touring. Its compact build also allows this bodypack to be easily hidden among clothing and costumes, so the speaker or performer gets great audio without a visual distraction.
Enjoy cable-like audio transmission—while enjoying the freedom of wireless. Choose from lavalier microphones, line sources, or instruments and connect it to the bodypack via its built-in 3-pin Lemo connector. The SK 9000’s user interface includes an icon-based menu for easy navigation, infrared synchronization for fast setup with a receiver, and safety measures to prevent accidental settings changes mid-performance.
The SK 9000 is compatible for use of energy packs with Lithium-Ion technology (sold separately), which is not only more environmentally friendly and cost-effective (since you will need to replace the batteries less often), but it will also maximize operating time between charges.
This transmitter is available in a variety of frequencies: A1-A4 at 470 - 558 MHz and A5-A8 at 550 - 638 MHz.
