Mounting the transmitter into a 19” rack

Do not fit the device feet when mounting the transmitter into a 19” rack.
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.
Make 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.
Make sure that the mechanical loading of the rack is even.When connecting to the power supply, observe the information indicated on the type
plate. Avoid circuit overloading. If necessary, provide overcurrent protection.
When 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.

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

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) and/or LOOP
OUT BAL R(II) (see also page 17).
The signal received from the AF input sockets BAL AF IN L(I) and BAL AF IN R(II)
is actively buffered and then routed to the output sockets LOOP OUT BAL L(I)
and LOOP OUT BAL R(II) . The AF output sockets will therefore work only when the transmitter is switched on and powered.

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 acces­sory). 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.
Connect the AC 3 antenna combiner to the BNC socket .

Synchronizing the transmitter with a receiver
When synchronizing your transmitter with a receiver, please observe the following:
Only use a transmitter and a receiver from the same frequency range (see the
type plate on the transmitter and the receiver).
Make sure that the desired frequencies are listed in the enclosed frequency
information sheet.
Make sure that the desired frequencies are approved and legal in your country
and, if necessary, apply for an operating license.
Synchronizing the transmitter with a receiver – individual operation
Upon delivery, transmitter and receiver are synchronized with each other. If, however, you cannot establish a transmission link between transmitter and receiver, you have to synchro­nize the channels of the devices:
Carry out the Easy Setup Sync function and then the Sync function (
The frequency of the selected frequency preset must be approved and legal in your country (see above).
Alternatively, you can set the channel on the transmitter manually:
Make sure that you set the transmitter to the same frequency bank and the same
channel as the receiver.

Synchronizing transmitters with receivers – multi-channel operation
Network operation
using the WSM
Operation without
network
In multi-channel operation, the transmitters are remote controlled via a PC running the “Wireless Systems Manager” (WSM) software.
Advantages of controlling the transmitters via the “Wireless Systems Manager (WSM) software:
• Detailed overview of all transmission and receiving channels
• Remote control of all transmitters in the network
• Combination of transmitters of different frequency ranges (see page 4)
Connect your transmitters and your PC in a network (see page 12).Switch your transmitters and your PC on.Launch the “Wireless Systems Manager” (WSM) software.To set up your multi-channel system, proceed as described in the instruction manual of
the “Wireless Systems Manager” (WSM) software.
Carry out the Easy Setup Sync function and then, for each transmission link, the Sync
function (
see page 15). The frequencies of the selected frequency presets must be approved and legal in your country (see above).
You can also freely select the frequencies and store these frequencies in the frequency banks “U1” to “U6”.
If you want to use the frequency banks “U1” to “U6”:
Make sure to use transmitters and receivers from the same frequency range (see page 4
and the type plates of the devices).
Only use frequencies that are approved and legal in your country (see page 21).
To ensure that the desired frequencies are intermodulation-free:
Contact your Sennheiser partner (see www.sennheiser.com).
Set each transmitter to the same frequency bank.On one of the transmitters, select a channel within this frequency bank (see page 20).Assign this channel one of the calculated transmission frequencies (see page 20).Synchronize a receiver with your transmitter ( ,
see page 15
).
OR
Manually set the receiver to the same frequency bank, channel and frequency that you
set on the transmitter.
Repeat for the remaining transmitters and receivers as described above.
