within the transmitter’s enclosure that may be of sufficient magnitude to constitute risk of
fire or electric shock.
2
Important safety instructions
This symbol is intended to alert the user to the risk of electric shock if the transmitter is
opened. There are no user serviceable parts inside. Refer servicing to qualified personnel only.
This symbol is intended to alert the user to the presence of important operating and maintenance instructions in the literature accompanying this transmitter.
Overloading
Do not overload wall outlets and extension cables as this may result in fire and electric shock.
Replacement parts
When replacement parts are required, be sure the service technician uses replacement parts
specified by Sennheiser or those having the same characteristics as the original part.
Unauthorized substitutions may result in fire, electric shock, or other hazards.
Safety check
Upon completion of any service or repairs to this device, ask the service technician to perform
safety checks to determine that the device is in safe operating order.
Danger of hearing damage due to high volumes
This is a professional transmitter. Commercial use is subject to the rules and regulations of
the trade association responsible. Sennheiser, as the manufacturer, is therefore obliged to
expressly point out possible health risks arising from use.
This transmitter is capable of producing sound pressure exceeding 85 dB(A). 85 dB(A) is the
sound pressure corresponding to the maximum permissible volume which is by law (in some
countries) allowed to affect your hearing for the duration of a working day. It is used as a
basis according to the specifications of industrial medicine. Higher volumes or longer durations can damage your hearing. At higher volumes, the duration must be shortened in order
to prevent hearing damage. The following are sure signs that you have been subjected to
excessive noise for too long a time:
• You can hear ringing or whistling sounds in your ears.
• You have the impression (even for a short time only) that you can no longer hear high
notes.
Intended use
Intended use of the SR 2000 IEM and SR 2050 IEM transmitters includes:
• having read these instructions, especially the chapter “Important safety instructions”,
• using the device within the operating conditions and limitations described in this instruction manual.
“Improper use” means using the device other than as described in these instructions, or
under operating conditions which differ from those described herein.

The SR 2000 IEM and SR 2050 IEM transmitters
With the SR 2000 IEM and SR 2050 IEM 2-channel/stereo monitoring transmitters, musicians, video and sound amateurs, reporters/broadcasters, etc. can directly monitor the
received sound signals without troublesome cables or monitor speakers being required. In
addition, the transmitters can also be used for any application where talkback signals are to
be transmitted.
Features of the SR 2000 IEM and SR 2050 IEM transmitters:
• Optimized PLL synthesizer and microprocessor technology
•Stereo/mono selection
• HDX noise reduction system
• Switching bandwidth of up to 75 MHz
• Safe configuration of a multi-channel system using the WSM
• Easy setup of a multi-channel system using the Easy Setup Sync function
The frequency bank system
The transmitters are available in 5 UHF frequency ranges with up to 3,000 transmission
frequencies per frequency range:
Aw:
Range
558 – 626
Range
516 – 558
500 600 700 800
Gw:
Range Bw:
626 – 698
Range
718 – 790
Cw:
Range Dw:
790 – 865
Each frequency range (Aw–Dw, Gw) offers 26 frequency banks with up to 32 channels each:
Channel 1 – frequency preset
Channel 2 – frequency preset
Frequency bank 1... 20
Channel 32 – frequency preset
Channel 1 – freely selectable frequency
Channel 2 – freely selectable frequency
Frequency bank U1 ... U6
Channel 32 – freely selectable frequency
4
Delivery includes
Each of the channels in the frequency banks “1” to “20” has been factory-preset to a fixed
transmission 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 (see
page 22).
Areas of application
The transmitters can be combined with the EK 2000 IEM diversity receiver. For more information, visit our website at www.sennheiser.com.
This receiver is available in the same UHF frequency ranges and is 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.
Delivery includes
The packaging contains the following items:
1 SR 2000 IEM transmitter or 1 SR 2050 IEM twin transmitter
3 mains cables (with EU, UK and US plug)

Putting the transmitter into operation
Setting up the transmitter on a flat surface
왘 Clean the base of the transmitter where you want to fix the device feet.
왘 Fit the device feet to the four corners of the transmitter.
왘 Place the transmitter on a flat, horizontal surface. Please note that the device feet can
leave stains on delicate surfaces.
Mounting the transmitter into a 19” rack
CAUTION! Risks when rack mounting the transmitter!
When installing the device in a closed or multi-rack assembly, please consider that, during
operation, the ambient temperature, the mechanical loading and the electrical potentials will
be different from those of devices which are not mounted into a rack.
왘 Sure that the ambient temperature within the rack does not exceed the permissible
temperature limit specified in the specifications.
왘 If necessary, provide additional ventilation.
왘 Make sure that the mechanical loading of the rack is even.
왘 When connecting to the power supply, observe the information indicated on the type
plate. Avoid circuit overloading. If necessary, provide overcurrent protection.
왘 When rack mounting, please note that intrinsically harmless leakage currents of the indi-
vidual mains units may accumulate, thereby exceeding the allowable limit value. As a
remedy, ground the rack via an additional ground connection.
왘 Slide the transmitter into the 19” rack.
왘 Secure the rack mount “ears” to the rack using four screws (not included in the
delivery).
Do not fit the device feet when mounting the transmitter into a 19” rack.
Connecting the antennas
You have the following options:
• For professional use, we recommend connecting a remote antenna and, if necessary, using
Sennheiser antenna accessories (see next section and the chapter “Connecting several
transmitters to a remote antenna” on page 9).
• If the transmitter is to be put into operation without a large amount of installation work,
you can:
– connect the supplied rod antenna to the rear of the transmitter (see page 9) or
– use the optional GA 3030 AM antenna front mount kit (see page 9).
