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.

Page 6
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.

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).

Connecting and positioning a remote antenna
Use a remote antenna when the transmitter position is not the best antenna position for
optimum transmission. You can choose between two antennas (see “Accessories” on
page 23):
• A 2003 UHF passive directional broadband antenna
• A 1031 passive omni-directional broadband antenna
왘 Use a low-attenuation 50-Ω cable to connect the antenna to the transmitter.
왘 If possible, use a short antenna cable and as little connections as possible, since long
cables and many connectors lead to an attenuation of the antenna signal.
왘 Position the antenna in the same room in which the transmission takes place.
왘 Observe a minimum distance of 1 m between the antenna and metal objects (including
reinforced concrete walls).
You can connect several transmitters to the same remote antenna (see next section).
Connecting several transmitters to a remote antenna
To make multi-channel systems, you should use the AC 3200 antenna combiner (optional
accessory). The AC 3200 allows you to operate up to eight transmitters with a single antenna
without virtually any intermodulation.
왘 Connect the AC 3200 antenna combiner to the BNC socket .
Connecting the rod antenna to the rear of the transmitter
The supplied rod antenna is suitable for all applications where the transmitter is to be put
into operation without a large amount of installation work.
왘 Connect the rod antenna to the BNC socket .
Mounting the antennas to the front of the rack
To mount the antenna connections to the front of the rack when rack mounting the transmitter, you require the GA 3030 AM antenna front mount kit (optional accessory).
The GA 3030 AM consists of:
• 2 BNC extension cables (screw-in BNC socket to BNC connector ),
• 2 antenna holders ,
•4 screws,
•2 washers ,
•2 nuts .
9
Page 11
Putting the transmitter into operation
왘 Guide the BNC connector of the BNC extension cable through the hole in the rack mount
“ear” .
왘 Connect the BNC connector to the antenna output .
왘 Screw the antenna holder to the BNC socket using the supplied washer and
nut .
왘 Secure the antenna holder to the rack mount “ear” of the transmitter using two of
the supplied screws.
If you are using the SR 2050 IEM twin transmitter:
왘 Mount the second BNC extension cable in the same way.

Connecting an audio source to the input sockets
왘 Use a suitable cable to connect the output of the audio source (e.g. mixing console) to the
¼” (6.3 mm) jack/XLR-3 combo socket BAL AF IN L(I) and/or BAL AF IN R(II) .
왘 Via the operating menu, adjust the transmitter’s input sensitivity. The input sensitivity is
adjusted via the “Sensitivity” menu item and is common for both inputs.
You can connect several transmitters to the same audio source (see next chapter).
Daisy chaining audio signals
The output sockets LOOP OUT BAL L and/or LOOP OUT BAL R allow you to daisy chain a
signal that is to be transmitted to all receivers from the mixing console to one transmitter
and then to the other transmitters. To do so, proceed as follows:
왘 Route a signal from the mixing console to the input socket (in this example: BAL AF IN R )
of transmitter A.

Connecting devices to the output sockets
왘 Use a suitable cable to connect the audio input of a device (e.g. a mixing console or an
additional SR 2000 IEM or SR 2050 IEM) to the output socket LOOP OUT BAL L(I) and/
or LOOP OUT BAL R(II) (see preceding chapter).
Connecting transmitters in a network
You can connect several transmitters in a network. The transmitters are remote controlled via
a PC running the “Wireless Systems Manager” (WSM) software. This software will assist in
the quick and safe configuration of multi-channel systems.
왘 Connect a standard network cable (at least Cat 5) to the LAN socket of the transmitter.
왘 Connect your transmitters to an Ethernet switch.
왘 Connect a PC to the Ethernet switch.
When a transmitter is properly connected to the Ethernet switch or the PC, the yellow
LED at the rear of the transmitter lights up.
For further information on network operation, refer to page 22.
The signal received from the AF input sockets BAL AF IN L(I) and BAL AF IN R(II)
is actively buffered and then routed to the output sockets LOOP OUT BAL L(I) and
LOOP OUT BAL R(II) . The AF output sockets will therefore work only when the trans-
mitter is switched on and powered.
The “Wireless Systems Manager” (WSM) software can be downloaded from the
corresponding product page on our website at www.sennheiser.com.

Synchronizing transmitters and EK 2000 IEM receivers via the infra-red interface
Synchronization allows you to quickly and easily transfer transmitter and receiver settings
from one device to the other, especially if you want to configure a multi-channel system.
There are two transfer directions:
1. Easy Setup Sync: Transfer from the receiver to one or several transmitters
Once you have performed a frequency preset scan with your receiver, you can use the
Easy Setup Sync function to transfer unused frequency presets from the receiver to the
transmitters via the infra-red interface. In order to configure a multi-channel system, you
use the diversity receiver to transfer the first unused channel from the selected frequency
bank to the first transmitter and the next unused channel to the second transmitter and
so on, thus ensuring that all transmitters of a multi-channel system operate on suitable
frequencies.
2. Sync: Transfer from a transmitter to a receiver
Once you have selected and set the desired receiver settings on the transmitter (either
manually or using the Easy Setup Sync function), you transfer these settings to a receiver.
This configures the receiver and establishes a transmission link between transmitter and
receiver.
Via the “Sync Settings” submenu, you can adjust the receiver parameters listed below and
activate or deactivate their transfer to an EK 2000 IEM receiver.
Setting Transferred receiver parameter
“Balance” Current balance setting (“−15”/“+15”)
“Squelch” Current squelch setting (“Off”, “5 dB” ... “25 dB”)
“Mode” Current audio mode setting (“Stereo”/“Focus”)
“High Boost” Current treble boost setting (“flat”/“High boost”)
“Auto Lock” Current lock mode setting (“active”/“inactive”)
