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.

Setting up the transmitter on a flat surface  
Place the transmitter on a flat, horizontal surface. Please note that the device feet can leave  
stains on delicate surfaces.  
The rack mount “ears” are designed to help protect the operating elements from  
damage or deformation, e.g. if the transmitter is dropped. Therefore, fasten the rack  
mount “ears”, even if you do not want to rack mount your transmitter.

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.

The input amplifier of the SR 300 IEM G3 is designed for line level input.  
Connecting external devices to the output sockets

Use a suitable cable to connect the input of an external device (e.g. a mixing console or  
an additional SR 300 IEM G3) to the output socket LOOP OUT BAL L(I) ¹ and/or LOOP  
OUT BAL R(II) Ƹ (see also page 17).  
The signal received from the AF input sockets BAL AF IN L(I) ƺ and BAL AF IN R(II)  
ƻ is actively buffered and then routed to the output sockets LOOP OUT BAL L(I) ¹  
and LOOP OUT BAL R(II) Ƹ. The AF output sockets will therefore work only when the  
transmitter is switched on and powered.  
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.

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.

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.

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:  
̈
Carry out the Easy Setup Sync function and then the Sync function (see page 15).  
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.

You can also freely select the frequencies and store these frequencies in the frequency banks  
U1” to “U6”.  
If you want to use the frequency banks “U1” to “U6”:  
̈
Make sure to use transmitters and receivers from the same frequency range (see page 4  
and the type plates of the devices).  
̈
Only use frequencies that are approved and legal in your country (see page 21).  
To ensure that the desired frequencies are intermodulation-free:  
̈
Contact your Sennheiser partner (see www.sennheiser.com).  
̈
̈
̈
̈
Set each transmitter to the same frequency bank.  
On one of the transmitters, select a channel within this frequency bank (see page 20).  
Assign this channel one of the calculated transmission frequencies (see page 20).
