Connecting external devices
Connecting external devices to the input sockets
̈ Use a suitable cable to connect the output of an external device (e.g. a mixing console or an
additional SR 300 IEM G3) to the input socket BAL AF IN L(I) ƺ and/or BAL AF IN R(II) ƻ
(see also page 17).
̈ Adjust the output level of your external device.
̈ 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).
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).
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.

ƻƺ
The input amplifier of the SR 300 IEM G3 is designed for line level input.
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.
