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.
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.
Putting the transmitter into operation

왘 Secure the rack mount “ears” of the supplied GA 3 rack adapter to the transmitter as
described on page 8.
왘 Secure the blanking plate to one of the rack mount “ears” using two recessed head
screws (M 6x10) (see diagram).
9
Putting the transmitter into operation
왘 Connect the antenna. You have the following options:
– You can connect the supplied rod antenna to the rear of the transmitter (see
page 8). In this case, insert the two blanking plugs into the holes of the blanking
plate (see diagram on page 9).
– You can use the AM 2 antenna front mount kit (see “Accessories and spare parts” on
page 36) 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.
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.
Rack mounting two transmitters
To mount two transmitters into a rack using the GA 3 rack adapter:
왘 Place the two transmitters side by side upside-down onto a flat surface.
10
왘 Secure the jointing plate to the transmitters using six recessed head screws (M 3x6).
왘 Secure the rack mount “ears” to the transmitters as described on page 8.
To mount the transmitters into the rack:
왘 Use remote antennas, if necessary in conjunction with the AC 3 antenna combiner.
For more information, visit the ew G3 product pages at www.sennheiser.com.
To mount the transmitters into the rack:
왘 Slide the transmitters into the 19" rack.
왘 Secure the rack mount “ears” to the 19" rack.
Putting the transmitter into operation
Connecting an audio source to the input sockets
왘 Use a suitable cable to connect the output of an audio source (e.g. a mixing console or an
additional SR 300 IEM G3) to the input socket BAL AF IN L(I) and/or BAL AF IN R(II)
(see also page 11).
왘 Adjust the output level of your external device.
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 (see page 20).
The input amplifier of the SR 300 IEM G3 is designed for line level input.

Connecting an audio source to the output sockets
왘 Use a suitable cable to connect the audio 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) and/or LOOP
OUT BAL R(II) (see also page 11).
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
transmitter is switched on and powered.
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 an audio source (e.g. a mixing console)
to one transmitter and then to the other transmitters.
To daisy chain an audio signal from one transmitter to the next:
왘 Route a signal from the mixing console to the input socket (in this example: BAL AF IN R

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
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).
Connecting the AC 3 antenna combiner to the BNC socket
To make multi-channel systems, you should use the AC 3 antenna combiner (see “Accessories
and spare parts” on page 36). 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.
왘 Connect the AC 3 antenna combiner to the BNC socket .
