OPERATING PRECAUTIONS
Make sure theAC mains voltage is correct and is the same as that printed on the rear of the amplifier.
Damage caused by connecting the amplifier to improper AC voltage is not covered by the three-year US
warranty. Make sure the power switch is off before making any input or output connections.
It is always a good idea to have the gain controls turned down during power-up to prevent speaker damage if
there is a high signal level at the inputs.
INPUT CONNECTING
Input connections are made via either the 3-pin XLR-type
connectors (Figure 1) or 6.35mm sockets on the rear side
of the amplifier.
OUTPUT CONNECTING
Load can be connected using banana plugs or spade lugs. A black binding post is considered “COM”, while the
three red binding posts are considered “hot”.
If the PROT Led goes on steadily and the buzzer sounds while power has been turned on and signal has been fed,
there must a trouble of output shorted. please turn it off and correct the trouble then turn it on again.

操作注意事项
本产品为公共广播专用设备，该产品的连接、使用以及维护等操作必须由受过专业培训的人员来完成。
电源电压应确实与本机相符,由电压不符造成的损坏不在保修之列。
所有输入输出连接好以前,不要通电；通电前最好把音量调至最小以防损坏扬声器。
当通电并输入信号后,如果保护指示灯点亮,即说明有输出短路故障.应立即切断电源,排除故障后再
重新加电。
输入之连接
所有输入均应连接于机器后面板之卡隆插口
（图 1）或 6.35mm 插口。
输出之连接
输出端子在后面板，可用香蕉插或铲形插连接。黑色乃
公共端，红色乃热端。
通常应使用“定压”端子输出，连接的扬声器应带线间
变压器，扬声器的总功率应小于功放的额定输出功率。
扬声器在近距离配置时也可用 P1 端子输出，此时连接的扬声器总阻抗应不小于 4欧。
