"Improper use" means using the AMXXR-30 other than as described in this instruction manual, or under operating conditions which differ from those described herein. 3 The AMXXR-30 active transmitter combiner The AMXXR-30 active transmitter combiner With the AMXXR-30 4-to-1 active transmitter combiner, the signals of up to four SR 300 IEM G3 type transmitters can be combined onto a single antenna. The integral active RF amplifiers ensure that the input signals are combined onto the common antenna output with no distribution attenuation. The AMXXR-30 incorporates DC distribution to enable simultaneous powering of up to four transmitters via its BNC sockets. A single NT 3-1 table top power supply (see "Accessories" on page 15) is required to power the AMXXR-30 and the connected transmitters. Using the GA 3 rack adapter (see "Accessories" on page 15), one AMXXR-30 and one stationary SR 300 IEM G3 type transmitter can be mounted into a 19" rack. For stacking the AMXXR-30, mount the optional stacking elements (see "Accessories" on page 15). The AMXXR-30 is suitable for the following areas of application: · Multi-channel monitoring systems for stage use · Multi-channel systems suitable for any application where talk-back signals are to be transmitted (e. g. studio) Delivery includes 1 AMXXR-30 active transmitter combiner 1 set of device feet 4 BNC cables 1 instruction manual You additionally require the NT 3-1 table top power supply with a suitable mains connector (see "Accessories" on page 15). 4 Operating controls Operating controls ³· DC ANTENNA COMBINER AMXXR-30 1 2 3 4 » RF IN 4 ANT RF IN 1 RF IN 2 RF IN 3 RF OUT DC OUT 12V/350mA USE NT 3-1 ONLY 13, 8V/3, 5A DC IN º ¶ ² ´¿ ³ STANDBY button · Operation indicator » 4 status LEDs ­ light up if the supply voltage for the transmitter is available at the BNC sockets RF IN 1 to RF IN 4 ­ go off if the BNC sockets RF IN 1 to RF IN 4 are shortcircuited or if transmitters are connected that are not of the ew G3 series (e. g. Connecting devices to the AMXXR-30 Connecting We recommend connecting a remote antenna and, if necessary, the antenna using Sennheiser antenna accessories (see "Accessories" on page 15). For more information, refer to the ew G3 product page at www. sennheiser. com. Connecting You can connect up to four stationary SR 300 IEM G3 type the transmitters transmitters to the AMXXR-30. The active transmitter combiner also incorporates DC distribution for powering the transmitters: RF IN 1 RF IN 2 RF IN 3 RF IN 4 DC OUT 12V/350mA USE NT 3-1 O 13 DC IN ² Connect the transmitter's antenna output to one of the BNC sockets RF IN 1 to RF IN 4 ². Transmitters of the ew G3 series do not require their individual power supply. Connecting the AMXXR-30 to the mains For powering the AMXXR-30 and the connected transmitters, you require the NT 3-1 table top power supply (see "Accessories" on page 15). It is designed for the AMXXR-30 and ensures safe operation. RF IN 2 RF IN 3 RF IN 4 Pass the cable of the NT 3-1 table top power supply through the cable grip ¿.
