The SKM 2000 radio microphone
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 and EM 2050
rack-mount receivers. 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 SKM 2000 radio microphone
The frequency bank system
The radio microphone is available in 5 UHF frequency ranges with up to
3,000 transmission frequencies per frequency range:
Each frequency range (Aw­Dw, Gw) offers 26 frequency banks with up to
64 channels each:
Each of the channels in the frequency banks "1" to "20" has been factory-
preset to a fixed frequency (frequency preset). The factory-preset
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 SKM 2000 product page on
our website at www.sennheiser.com.
The frequency banks "U1" to "U6" allow you to freely select and store
frequencies. It might be that these frequencies are not intermodulation-
free.
