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)

(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

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.
