Connecting External Devices - Sennheiser SR 300 IEM Manual

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
PUSH PUSH
an additional SR 300 IEM) to the input socket
(see also page 15).
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

an additional SR 300 IEM) 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. Ready-
made antenna cables from Sennheiser are available as accessories with length of 1 m, 5
m and 10 m.
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
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.
