[. . . ] Connect the MR3000 to your audio system using the appropriate connector on the rear panel. It is preferable to use the 3-pin XLR connector since its balanced circuitry minimizes the potential for electrical interference and can be used with long cable runs. Switch on the receiver with the front-panel power switch. Attach either the supplied ¼-wave antennas or two externally mounted antennas to the antenna connectors on the rear panel of the MR3000. Be sure and tighten the connectors securely. If the supplied ¼-wave antennas are used, they must be oriented at a 90o angle as shown in Figure 1. Unlike other diversity wireless systems, two antennas are needed for the MS3000 to operate correctly. Figure 1 Figure 4 Figure 3 5. Open the battery compartment door on the handheld transmitter or the bodypack and install a 9-volt alkaline battery (see Figures 3 and 4). 8. 4 volt Ni-Cad batteries may be used but will yield noticeably shorter operational time and slightly lower performance. Figure 2 page 4 MS3000 OWNERS MANUAL 6. When the battery is installed, you may plug in the microphone to the bodypack or simply switch on the handheld transmitter and begin operation. When the system is first operated, the gain of the transmitter should be adjusted to the vocalist or speaker who will be using it. Speak or sing as loudly as possible into the microphone. Observe the audio level meter on the receiver. Figure 5 DIVERSITY 2 POWER 1 SQUELCH 1 To assemble the rack mount adapters to the unit(s) and install into a rack, proceed as follows: 1. Remove the front Phillips head screws from each side of each unit. Align the correct rack ear or bracket with the holes on the side of the unit. Insert an additional screw (provided in the parts pack) into the remaining hole. Repeat this step for the opposite side of the unit. For double mounting of two systems, proceed as follows: RF LEVEL 2 3 4 5 AUDIO LEVEL:dB -20 10 -5 0 +3 R MR3000 Adjust the gain control on the transmitter (see Figures 2 and 4) to prevent over or under-modulation. The gain should be adjusted so that the signal peaks are no more than +0 dB and that there is at least 10 dB of audio level meter indication. The squelch control on the front of the receiver may be adjusted to increase range or reduce interference. If the squelch control is being adjusted, it should be adjusted with the transmitter off. CAUTIONDECREASING SQUELCH WILL MAKE THE SYSTEM MORE SUSCEPTIBLE TO OUTSIDE INTERFERENCE! [. . . ] It is always best to place your receiver as far away from these devices as possible to minimize this potential source of interference.
