5、 by conn ect ing the amplifier to improper AC voltage is not covered by the three-year US warra nty.Make sure the power switch is off before making any in put or output connections.CONNECTING INPUTSFigure 1 3-pin XLR-type connectorsIt is always a good idea to have the gain controls turned down durin

6、g power-up to prevent speaker damage if there is a high sig nal level at the in puts.In put connections are made via either the 3-pi n XLR -type connectors (Figure 1) or mm sockets on the rear side of the amplifier.CONNECTING OUTPUTSLoad can be connected using banana plugs or spade lugs. A black bin

7、ding post is considered “ COM , while the three red binding posts are considered “hot,"and the voltage is 38V (different from the model) , 70V, and 100V.Note:Never connect the “ hot ” term in alstogether.When connecting load ( speakers) , it is better to use one pair of output term in als only.

8、If the PROT Led goes on steadily while power has bee n turned on and sig nal has bee n fed, there must be a trouble of output shorted.

14、输出功率相当。扬声器在近距离配置时也可用“定阻” （416Q ）端子输出，相应地此时扬声器的总阻抗应为416Q。宜只选用一对输出端子；任何时候都不应把两个“热端”连接在一起。性能规格规格PA3002PA4002PA5002额定输出功率350W450W650W输入灵敏度1V信噪比> 80dB阻尼系数200:1共模抑制不小于90dB.频响50Hz15kHz ± 3dB总谐波失真4 /1kHz< %上升速率>15V/microsec ond冷却方式强迫风冷指示灯电源”，削顶”，信号”，保护”和“超温”保护上电，高温，直流，短路.电源AC 220240V / 5060 Hz耗电量700W750W1000W尺寸88 4
