5、tem uses a radial horn with a high-frequency compression driver,a 800 Hz crossover network, and a 12 inch low- frequency loudspeaker that is precisely balanced and integrated in a tuned-port enclosure. The Rauland US-0165 radial horn is of durable cast aluminum construction. It provides closely cont

6、rolled, smooth 90 horizontal and 40 vertical dispersion characteristics. The Rauland US-0149 driver provides the highest degree of reliability, with remarkable dynamic range and power handling capacity. The Rauland US-0162 12- inch,low-frequency speaker in its tuned-port enclosure is outstanding for

7、 its ability to handle in excess of 50 watts RMS with undistorted full-bodied bass response. The MLS-3A enclosure is ruggedly built of 3/4 high-density par- ticle board and uses fiberglass padding where acoustically required. The enclosure is finished in an easily retouchable charcoal black color an

8、d includes a matching charcoal black readily removable cloth grille. The enclosure may be refinished to meet custom installation requirements. The separately supplied MK-6 Mounting Kit permits safe, convenient suspension mounting. 4. INSTALLATION 4.1 Equipment Damaqed In Transit This equipment has b

9、een carefully inspected and tested at the factory prior to shipment. If the equipment was damaged in transit, notify the transportation company immediately to place your claim. 4.2 Mountinq The speaker system may be placed in an alcove or similar incon- spicious location,or may be suspended from a c

10、eiling or structural supporting beam. Suspended mounting should be made using the optional (separately supplied) MK-6 speaker Mounting Kit. Installation in- structions are provided with the speaker mounting kit. 4.3 Wiring and Connections Use two-conductor,twisted-pair wire to interconnect the speak

11、er system to the audio amplifier output. Wire size and maximum wire length is shown in TABLE 1. Use spade lugs to terminate the wire at each end for connection to the available screw terminals.

13、 low-frequency speaker. When properly balanced, the same: the high and low-frequency response will be neither frequency range being accentuated or attenuated. This adjustment is most effectively made using a equalizer; which is built-into several different Rauland amplifier models, or may be purchas

14、ed separately. Best sound balancing is obtained when the sound pressure level, measured at a fixed reference point, is the same below and above the 800 Hz crossover frequency. This is readily determined using one octave of pink noise centered near 400 Hz and another octave of pink noise centered nea
