Putting the transmitter into operation
Setting up the transmitter on a flat surface
̈ Clean the base of the transmitter where you want to fix the device feet.
̈ Fit the device feet to the four corners of the transmitter.
̈ Place the transmitter on a flat, horizontal surface. Please note that the device feet can
leave stains on delicate surfaces.
Mounting the transmitter into a 19” rack
̈ Slide the transmitter into the 19” rack.
̈ Secure the rack mount “ears” ³ to the rack using four screws (not included in the
delivery).
Connecting the antennas
You have the following options:
• For professional use, we recommend connecting a remote antenna and, if necessary, using
Sennheiser antenna accessories (see next section and the chapter “Connecting several
transmitters to a remote antenna” on page 9).
• If the transmitter is to be put into operation without a large amount of installation work,
you can:
– connect the supplied rod antenna to the rear of the transmitter (see page 9) or
– use the optional GA 3030 AM antenna front mount kit (see page 9).
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.
̈ Sure that the ambient temperature within the rack does not exceed the permissible
temperature limit specified in the 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.
