Designed to work seamlessly with Digital 9000 receivers, this transmitter offers pristine audio quality and uncompromising reliability. Featuring a compact, lightweight magnesium housing, the SK 9000 is both moisture-resistant and comfortable to wear, making it ideal for performers, presenters, and audio professionals.

Wide Compatibility with Lavalier and Headset Microphones
The SK 9000 is compatible with a wide range of Sennheiser microphones, including lavaliers such as the MKE 1, MKE 2, MKE Essential, and MKE 40, as well as headset options like the HSP 2, HSP 4, and SL Headmic 1-4. This versatility ensures that the transmitter meets the needs of various applications, from theater productions to corporate presentations. It is also compatible with the EM 9046 SU receiver and, in Long Range mode, works seamlessly with the EM 6000 and EK 6042 receivers.

Flexible Power Options for Extended Use
The SK 9000 can be powered by the BA 61 rechargeable battery pack or the B 61 battery case with three AA batteries (both sold separately). The BA 61 provides up to 6.5 hours of continuous operation, ensuring uninterrupted performance for long events. Additionally, the transmitter displays battery status on both the unit and the receiver, enabling remote monitoring to prevent unexpected interruptions.

Exceptional Audio Quality with Advanced Modes
The SK 9000 supports two audio modes to suit different production needs. The Long Range (LR) mode utilizes Sennheiser’s proprietary SeDAC audio codec to deliver crystal-clear sound with a robust 25mW RF output. For pristine digital audio, the High Definition (HD) mode uses uncompressed transmission, operating at 10mW for applications where audio clarity is paramount. These options ensure professional sound quality in any setting.

Reliable Performance in Challenging RF Environments
Featuring an intermodulation-free transmission design, the SK 9000 ensures stable performance even in crowded RF environments. The 88 MHz tuning bandwidth provides greater flexibility for finding available frequencies, making it an ideal choice for high-profile productions and live events where reliability is crucial. The equidistant frequency grid allows for seamless operation of multiple transmitters on stage.

Durable and Intuitive Design for Seamless Operation
The SK 9000 is constructed with a lightweight magnesium housing that is rugged enough to endure the rigors of live production. Its moisture-resistant LEMO-type mic input enhances durability, while the backlit LCD and intuitive menu-driven interface make setup and operation effortless. Features like IR synchronization, adjustable gain, and customizable low-cut filters further streamline the user experience.

Advanced Security and Practical Features
The SK 9000 offers Digital 9000 Series encryption for secure, private transmission, ensuring sensitive audio remains protected. Additional features include a cable menu that allows musicians to emulate classic guitar tones, an automatic lock mode to prevent accidental setting changes, and adjustable gain in 3 dB increments for precise control over input levels.
