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:  
Range Aw:  
Range Gw:  
Range Bw:  
626 – 698  
Range Cw:  
718 – 790  
Range Dw:  
790 – 865  
516 – 558 558 – 626  
500  
600  
700  
800  
Each frequency range (Aw–Dw, Gw) offers 26 frequency banks with up to  
64 channels each:  
Channel 1 – frequency preset  
Channel 2 – frequency preset  
Frequency bank 1 ... 20  
Channel 64 – frequency preset  
Channel 1 – freely selectable frequency  
Channel 2 – freely selectable frequency  
Frequency bank U1 ... U6  
Channel 64 – freely selectable frequency  
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  
The frequency banks “U1” to “U6” allow you to freely select and store  
frequencies. It might be that these frequencies are not intermodulation-  
free.

The radio microphone adds an inaudible signal, known as the pilot tone, to  
the transmitted signal. The receiver detects and evaluates the pilot tone.  
The pilot tone supports the receiver’s squelch function, thus protecting  
against interference due to RF signals from other devices.

Synchronizing the radio microphone with a receiver  
Synchronizing the radio microphone with  
a receiver  
When synchronizing the radio microphone with a receiver, please observe  
the following:  
̈ Only use a transmitter and a receiver from the same frequency  
range (see the type plates on the transmitter and the  
receiver).  
̈ Make sure that the desired frequencies are listed in the  
enclosed frequency information sheet.  
̈ Make sure that the desired frequencies are approved and legal  
in your country and, if necessary, apply for an operating  
license.  
Synchronizing the radio microphone with the  
receiver – individual operation  
Upon delivery, the radio microphone and the receiver are synchronized  
with each other. If, however, you cannot establish a transmission link  
between radio microphone and receiver, you have to synchronize the  
channels of the devices.  
For information on automatic synchronization of the radio microphone  
with the receiver (individual operation), refer to the instruction manual of  
the receiver. This information is marked with the  
icon.  
Alternatively, you can set the channel on the radio microphone manually:  
̈ Make sure that you set the radio microphone to the same frequency  
bank and the same channel as the receiver (see page 21).  
If you still cannot establish a transmission link, read the chapter “If a  
problem occurs ...” on page 30.  
Synchronizing radio microphones with receivers –  
multi-channel operation  
Combined with 2000 series receivers, SKM 2000 radio microphones can  
form transmission links that can be used in multi-channel systems.  
For information on automatic synchronization of radio microphones with  
receivers (multi-channel operation), refer to the instruction manual of  
your receiver. For more information on multi-channel operation, visit the  
SKM 2000 product page at www.sennheiser.com.

Cleaning the radio microphone  
Cleaning the radio microphone  
CAUTION! Liquids can damage the electronics of the radio  
microphone!  
Liquids entering the housing of the device can cause a  
short-circuit and damage the electronics.  
̈ Keep all liquids away from the radio microphone.  
̈ Do not use any solvents or cleansing agents.  
̈ Use a cloth to clean the radio microphone from time to time.  
To clean the sound inlet basket of the microphone head:  
̈ Unscrew the upper sound inlet basket from the microphone head by  
turning it counterclockwise.  
CAUTION! Liquids will damage the microphone head!  
Liquids will damage the microphone head.  
̈ Only clean the upper sound inlet basket.  
̈ Remove the foam insert.  
̈ To clean the sound inlet basket:  
– Use a slightly damp cloth to clean the upper sound inlet basket from  
the inside and outside.  
OR  
– Scrub with a brush and rinse with clear water.  
̈ If necessary, clean the foam insert with a mild detergent or replace the  
foam insert.  
̈ Dry the upper sound inlet basket.  
̈ Dry the foam insert.  
̈ Reinsert the foam insert.  
̈ Replace the sound inlet basket on the microphone head and screw it  
tight.  
You should also clean the contact rings of the microphone head from time  
to time:  
̈ Wipe the contact rings of the microphone head with a cloth.

Recommendations and tips  
Recommendations and tips  
... for optimum sound  
• Hold the radio microphone in the middle of the microphone body.  
Holding it close to the sound inlet basket will influence the radio  
microphone’s pick-up pattern.  
• You can vary the bass reproduction by increasing/decreasing the  
talking distance.  
• For best results, make sure that the sensitivity is correctly adjusted.  
... for optimum reception  
• Transmission range depends to a large extent on location and can vary  
from about 10 m to about 150 m. There should be a “free line of sight”  
between transmitting and receiving antennas.  
• To avoid overloading the receiver, observe a minimum distance of 5 m  
between transmitting and receiving antennas.  
• Only hold the radio microphone by its body. If you touch the antenna  
of the radio microphone, the transmission range will be considerably  
reduced.  
... for multi-channel operation  
• For multi-channel operation, you should only use the channels within  
one frequency bank. Each of the frequency banks “1” to “20”  
accommodates factory-preset frequencies which are intermodulation-  
free.  
• When using several transmitters simultaneously, interference can be  
avoided by maintaining a minimum distance of 20 cm between two  
transmitters.
