The SK 2000 bodypack transmitter
The SK 2000 bodypack transmitter
This bodypack transmitter 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 bodypack transmitter can be combined with the EM 2000 or EM 2050
rack-mount 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.

700
800
Each frequency range (Aw–Ew, Gw, GBw) 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
4
Delivery includes
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 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.
Delivery includes
The packaging contains the following items:
1 SK 2000 bodypack transmitter
2 AA size batteries, 1.5 V
1 instruction manual
1 frequency information sheet
1 supplement “Framework requirements and restrictions on the use of
radio microphones”

Inserting the batteries/accupack
For powering the bodypack transmitter, you can either use two 1.5 V AA
size batteries or the rechargeable Sennheiser BA 2015 accupack or the
DC 2 power adapter (accessories, visit www.sennheiser.com).
왘 Open the battery compartment by pushing the two catches 쐈 in the
direction of the arrows and open the cover 쐅.

왘 Insert the two batteries or the accupack as shown above. Please
observe correct polarity when inserting the batteries/accupack.
왘 Close the battery compartment.
The battery compartment cover 쐅 locks into place with an audible
click.
Charging the accupack
To charge the BA 2015 accupack (accessory, visit www.sennheiser.com)
installed in the bodypack transmitter:
왘 Insert the bodypack transmitter into the L 2015 charger (accessory,
visit www.sennheiser.com).
The L 2015 charger can only charge the combination BA 2015

Putting the bodypack transmitter into operation
Connecting the microphone cable/instrument cable
The audio input is designed for the connection of both condenser microphones and instruments (e.g. guitars). DC powering of the condenser
microphones is via the MIC/LINE socket 쐃 (3-pole special audio socket).
왘 Use one of the recommended Sennheiser microphones or the CI 1-4
instrument cable (see page 3).
왘 Connect the 3-pin special audio connector 씊 from the Sennheiser
microphone or instrument cable to the MIC/LINE socket 쐃.

Putting the bodypack transmitter into operation
Attaching the bodypack transmitter to clothing
You can use bodypack pouch or the belt clip 씍 to attach the bodypack
transmitter to clothing (e.g. belt, waistband).
씍
The belt clip is detachable so that you can also attach the transmitter with
the antenna pointing downwards. To do so, withdraw the belt clip 씍 from
its fixing points and attach it the other way round.
The belt clip 씍 is secured so that it cannot slide out of its fixing points
accidentally.
To detach the belt clip:
왘 Lift one side of the belt clip as shown.
왘 Press down the belt clip at one fixing point and pull it out of the transmitter housing.
왘 Repeat for the other side.

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