Sennheiser EK 300 IEM G3 User Manual

Putting the devices into operation

12

Connecting 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 G3) to the input socket 

BAL AF IN L(I)

 

and/or 

BAL AF IN R(II)

(see also page 13).

왘

Adjust the output level of your external device.

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 (see page 24).

Connecting 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 G3) to the output socket 

LOOP OUT BAL L(I)

and/or

 LOOP OUT

BAL R(II)

(see also page 13).

Connecting a remote antenna to the BNC socket and positioning the antenna

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. 

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 any intermodulation. In addition, the AC 3 incorporates DC distribution to
enable simultaneous powering of up to four transmitters via its BNC sockets.

왘

Connect the AC 3 antenna combiner to the BNC socket

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

IC 2099A-G3SREK

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.
