OPERATING PRECAUTIONS
Make sure the AC main 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.

CONNECTING INPUTS Input connections are made via either the 3-pin XLR-type connectors (Figure 1 or mm sockets on the rear side of the amplifier. ground 1 2
signal3

Figure 1 3-pin XLR-type connectors

CONNECTING OUTPUTS 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”, and the voltage is 38V（different from the model）, 70V, and 100V.

Note: Never connect the“hot”terminals together.
When connecting load（speakers）, it is better to use one pair of output terminals only. If the PROT Led goes on steadily while power has been turned on and signal has been fed, there must be a trouble of output shorted. Please turn the unit off and correct the trouble then turn it on again.

操作注意事项
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。 当通电并输入信号後,如果保护指示灯(PROT点亮,即说明有输出短路故障.应即切断电源,排除故障後重新加电. 输入之连接
所有输入均应连接於机器後面板之卡隆插口（图1）或 mm插口。

信号（热端）3 图 1 三线卡隆插

输出之连接

输出端子在後面板，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，此 时各个扬声器应带线间变压器，扬声器的总功率应与功放的额定输出功率相当。
扬声器在近距离配置时也可用“定阻”（4～16Ω）端子输出，相应地此时扬声器的总阻抗应为4～16Ω。 注意：
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。
