The SKM 2000 radio microphone
This radio microphone is part of the 2000 series. With this series,
Sennheiser offers high-quality state-of-the-art RF transmission systems
with a high level of operational reliability and ease of use. Transmitters
and receivers permit wireless transmission with studio-quality sound.
Features of the 2000 series:
• Optimized PLL synthesizer and microprocessor technology
• HDX noise reduction system
•Pilot tone squelch control
• True diversity technology
• Switching bandwidth of up to 75 MHz
• Increased immunity to intermodulation and interferences in multi-
channel operation
Areas of application
The radio microphone can be combined with the EM 2000 or EM 2050 rackmount receiver. The receivers are available in the same UHF frequency
ranges and are equipped with the same frequency bank system with
factory-preset frequencies. An advantage of the factory-preset frequencies is that
• a transmission system is ready for immediate use after switch-on,
• several transmission systems can be operated simultaneously on the
preset frequencies without causing intermodulation interference.

The frequency bank system
The radio microphone is available in 6 UHF frequency ranges with up to
3,000 transmission frequencies per frequency range:
Range Aw:
516
500 600 700 800
– 558
Range Gw:
558 – 626
Range Bw:
626 –
698
Range Cw:
718 –
790
Range Dw:
790 – 865
Each frequency range (Aw–Dw, Gw) offers 26 frequency banks with up to
64 channels each:
Each of the channels in the frequency banks “1” to “20” has been factorypreset to a fixed transmission frequency (frequency preset). The factorypreset frequencies within one frequency bank are intermodulation-free.
These frequencies cannot be changed.
For an overview of the frequency presets, please refer to the supplied
frequency information sheet. Updated versions of the frequency information sheet can be downloaded from the corresponding product page on our
website at www.sennheiser.com.
The frequency banks “U1” to “U6” allow you to freely select and store
transmission frequencies. It might be that these transmission frequencies
are not intermodulation-free.
