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.
왘Make 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.
왘Make sure that the mechanical loading of the rack is even.
왘When connecting to the power supply, observe the information indicated on the type
plate. Avoid circuit overloading. If necessary, provide overcurrent protection.
왘When 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.

additional SR 300 IEM G3) to the input socket BAL AF IN L(I)  and/or BAL AF IN R(II) 
(see also page 17).
왘Adjust the output level of your external device.
왘Via 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).
Connecting external devices to the output sockets
왘Use 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) and/or LOOP
OUT BAL R(II) (see also page 17).
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
왘Use a low-attenuation 50-Ωcable to connect the antenna to the transmitter.
왘If 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.
왘Position the antenna in the same room in which the transmission takes place.
왘Observe 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.
