Putting the transmitter into operation

Connecting external devices
Connecting external devices to the input sockets
왘
Use a suitable cable to connect the output of an external device (e.g. a mixing console or
an additional SR 300 IEM) to the input socket
BAL AF IN L (I)
and/or
BAL AF IN R (II)
(see also page 15).
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.
Connecting external devices to the output sockets
왘
Use a suitable cable to connect the input of an external device (e.g. a mixing console or
an additional SR 300 IEM) to the output socket
LOOP OUT BAL L(I)
and/or
LOOP OUT
BAL R(II)
(see also page 15).
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. Ready-
made antenna cables from Sennheiser are available as accessories with length of 1 m, 5
m and 10 m.
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 (optional
accessory). The AC 3 allows you to operate up to four transmitters with a single antenna
without virtually no intermodulation.
In addition, the AC 3 incorporates DC distribution to enable simultaneous powering of up to
four transmitters via its BNC sockets.

The signal of the input sockets
BAL AF IN L (I)
and
BAL AF IN R (II)
is actively
decoupled and then distributed to the output sockets
LOOP OUT BAL L (I)
and
LOOP OUT BAL R (II)
. You can therefore use the output sockets only when the
transmitter is switched on.
