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 multichannel 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:
516 – 558
500
Range Gw:
558 – 626
600
Range Bw:
626 – 698
Range Cw:
718 – 790
700
Range Dw:
790 – 865
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 factorypreset 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 intermodulationfree.

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 intermodulationfree.
• When using several transmitters simultaneously, interference can be
avoided by maintaining a minimum distance of 20 cm between two
transmitters.
