Fitting the device feet

Connecting the

rod antenna

Setting up the transmitter on a flat surface

Place the transmitter on a flat, horizontal surface. Please note that the device feet can leave stains on delicate surfaces.

The rack mount “ears” are designed to help protect the operating elements from damage or deformation, e.g. if the transmitter is dropped. Therefore, fasten the rack mount “ears”, even if you do not want to rack mount your transmitter.

To fasten the rack mount “ears” :

Unscrew and remove the two recessed head screws (M4x8) on each side of the transmitter (see left-hand diagram).

Secure the rack mount “ears” to the sides of the transmitter using the previously removed recessed head screws (see right-hand diagram).

Do not fit the device feet when mounting the transmitter into a 19" rack.

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.

The supplied rod antenna % is suitable for use in good reception conditions.

Connect the rod antenna % (see diagram on page 9).

Putting the transmitter into operation

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 individual mains units may accumulate, thereby exceeding the allowable limit value. As a remedy, ground the rack via an additional ground connection.

Rack mounting one transmitter

Secure the rack mount “ears” of the supplied GA 3 rack adapter to the transmitter as described on page 8.

Secure the blanking plate to one of the rack mount “ears” using two recessed head screws (M 6x10) (see diagram).

Putting the transmitter into operation

Connect the antenna. You have the following options:

–You can connect the supplied rod antenna % to the rear of the transmitter (see page 8). In this case, insert the two blanking plugs into the holes of the blanking plate (see diagram on page 9).

–You can use the AM 2 antenna front mount kit (see “Accessories and spare parts” on page 36) and mount the rod antenna to the blanking plate .

–You can use a remote antenna, if necessary in conjunction with the AC 3 antenna combiner.

Slide the transmitter with the mounted blanking plate into the 19" rack.

Secure the rack mount “ear” and the blanking plateto the 19" rack.

Rack mounting two transmitters

To mount two transmitters into a rack using the GA 3 rack adapter:

Place the two transmitters side by side upside-down onto a flat surface.

Secure the jointing plateto the transmitters using six recessed head screws (M 3x6).

Secure the rack mount “ears”to the transmitters as described on page 8.

To mount the transmitters into the rack:

Use remote antennas, if necessary in conjunction with the AC 3 antenna combiner. For more information, visit the ew G3 product pages at www.sennheiser.com.

To mount the transmitters into the rack:

Slide the transmitters into the 19" rack.

Secure the rack mount “ears” to the 19" rack.

Connecting an audio source to the input sockets

Use a suitable cable to connect the output of an audio source (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 11).

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 an audio source to the output sockets

Use a suitable cable to connect the audio 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 11).

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.

Daisy chaining audio signals

The output sockets LOOP OUT BAL L and/or LOOP OUT BAL R allow you to daisy chain a signal that is to be transmitted to all receivers from an audio source (e.g. a mixing console) to one transmitter and then to the other transmitters.

To daisy chain an audio signal from one transmitter to the next:

Route a signal from the mixing console to the input socket (in this example: BAL AF IN R) of transmitter A.

Connect the output socket LOOP OUT BAL R of transmitter A to the input socket BAL AF IN R of transmitter B.

Connect the output socket LOOP OUT BAL R of transmitter B to the input socket BAL AF IN R of transmitter C.

Repeat for the other transmitters.

The AF output sockets LOOP OUT BAL L(I) and/or LOOP OUT BAL R(II) will work only when the transmitter is switched on and powered (see page 11).

Putting the transmitter into operation

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-channelsystems, youshould use the AC 3 antenna combiner (see“Accessories and spare parts” on page 36). 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 .
