• Danger due to high volumes
This product is also intended for professional use. Commercial use is subject to the safetyat-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
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.
EK 300 IEM G3 diversity receiver
Do not place the product near any heat sources such as radiators, heat registers, stoves, or
other devices (including amplifiers) that produce heat.
Intended use of the system
Intended use of the ew 300 IEM G3 series system includes:
• having read this instruction manual especially the chapter “Important safety instructions”,
• using the products within the operating conditions and limitations described in this
instruction manual.
“Improper use” means using the products other than as described in these instructions, or
under operating conditions which differ from those described herein.

Putting the devices into operation
Putting the devices into operation
Putting the SR 300 IEM G3 transmitter into operation
When using more than one transmitter, we recommend connecting remote
antennas and, if necessary, using Sennheiser antenna accessories. Fore more
information, visit the ew G3 product page at www.sennheiser.com.
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.
To fasten the rack mount “ears” :
Fitting the device feet
Connecting the
rod antenna
왘 Unscrew and remove the two recessed head screws (M4x8) on each side of the
transmitter.
왘 Secure the rack mount “ears” to the sides of the transmitter using the previously
removed recessed head screws.
Do not fit the device feet when mounting the transmitter into a 19” rack.
Clean the base of the transmitter where you want to fix the device feet.
왘
왘 Fit the device feet to the four corners of the transmitter.
The supplied rod antenna is suitable for use in good reception conditions.
왘 Connect the rod antenna to the BNC socket .

Putting the devices into operation
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 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.
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
individual mains units may accumulate, thereby exceeding the allowable limit value. As a
remedy, ground the rack via an additional ground connection.
Rack mounting one
transmitter
왘 Secure the rack mount “ears” of the supplied GA 3 rack adapter to the transmitter as
described on page 9.
왘 Secure the blanking plate to one of the rack mount “ears” using two recessed head
screws (M 6x10) (see diagram).
Do not fit the device feet when mounting the transmitter into a 19” rack.
10
왘 Connect the antenna. You have the following options:
– You can connect the supplied rod antenna
(see page 9). In this case, insert the two blanking plugs into the holes of the
blanking plate.
– You can use the AM 2 antenna front mount kit (optional accessory) and mount the rod
antenna to the blanking plate .
– You can use a remote antenna, if necessary in conjunction with the AC 3 antenna
combiner.
to the rear of the transmitter
왘 Slide the transmitter with the mounted blanking plate into the 19” rack.
왘 Secure the rack mount “ear” and the blanking plate to the 19” rack.
