Important safety instructions
Danger due to high volumes
This product is also intended for professional use. Commercial use is subject to the safety-at-
work regulations. Sennheiser, as the manufacturer, is therefore obliged to expressly point out
possible health risks arising from use.
This product 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 dura-
tions 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 300 IEM G3 transmitter includes:
• having read this instruction manual especially the chapter “Important safety instructions”,
• using the product within the operating conditions and limitations described in this instruc-
tion manual.
“Improper use” means using the product other than as described in these instructions, or
under operating conditions which differ from those described herein.

Mounting the transmitter into a 19” rack
Do not fit the device feet when 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.
̈
Make sure that the ambient temperature within the rack does not exceed the permissible
temperature limit specified in the SR 300 IEM G3 specifications. If necessary, provide
additional ventilation.
̈
̈
Make sure that the mechanical loading of the rack is even.
When connecting to the power supply, observe the information indicated on the type
plate. Avoid circuit overloading. If necessary, provide overcurrent protection.
̈
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.

Connecting a remote antenna to the BNC socket
Use a remote antenna when the transmitter position is not the best antenna position for
optimum transmission. You can choose between two antennas:
• A 2003 UHF passive directional antenna
• A 1031 passive omni-directional antenna
̈
̈
Use a low-attenuation 50-Ω cable to connect the antenna to the transmitter.
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.
̈
̈
Position the antenna in the same room in which the transmission takes place.
Observe a minimum distance of 1 m between the antenna and metal objects (including
reinforced concrete walls).
Connecting the AC 3 antenna combiner to the BNC socket
To make multi-channel systems, you should use the AC 3 antenna combiner (optional acces-
sory). The AC 3 allows you to operate up to four transmitters with a single antenna without
virtually any intermodulation.
In addition, the AC 3 incorporates DC distribution to enable simultaneous powering of up to
four transmitters via its BNC sockets.

Synchronizing transmitters and receivers via the infra-red
interface
Easy Setup Sync function (EK 300 IEM G3 -> SR 300 IEM G3)
Once you have performed a frequency preset scan with your EK 300 IEM G3 diversity receiver
(see the instruction manual of the 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. The diversity receiver transfers the first unused channel from the current frequency
bank to the first transmitter and the next unused channel to the second transmitter and
so on.
Sync function (SR 300 IEM G3 -> EK 300 IEM G3)
On the other hand, you can use the Sync function to adjust settings for your EK 300 IEM G3
diversity receiver directly on your SR 300 IEM G3 rack-mount transmitter and transfer theses
settings to the receiver via the infra-red interface.
Via the “Sync Settings” submenu, you can adjust the parameters listed below and activate or
deactivate their transfer to the receiver (see page 20).

Synchronizing the transmitter with a receiver
When synchronizing your transmitter with a receiver, please observe the following:
̈
̈
̈
Only use a transmitter and a receiver from the same frequency range (see the
type plate 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 transmitter with a receiver – individual operation
Upon delivery, transmitter and receiver are synchronized with each other. If, however, you
cannot establish a transmission link between transmitter and receiver, you have to synchro-
nize the channels of the devices:
̈
The frequency of the selected frequency preset must be approved and legal in your
country (see above).
Alternatively, you can set the channel on the transmitter manually:
̈
Make sure that you set the transmitter to the same frequency bank and the same
channel as the receiver.
