OPERATING PRECAUTIONS
1. Make sure the AC 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.
2. 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.
3. If the PROT Led goes on steadily 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.
CONNECTING INPUTS
Input connections are made via either the 3-pin XLR-type
connectors (Figure1/2 ) or 6.35mm sockets on the rear side of the
amplifier.
CONNECTING OUTPUTS
Output terminals are on the rear panel. 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”.
Usually make use of “fixed voltage” (70V or 100V) output,
while the each loudspeaker should use a separate transformer and
the total power of connecting loudspeakers should be less than rated power of amplifier.
Loudspeaker which close to the amplifier also make use of P1 output, while the total resistance of connecting
loudspeakers should accord with 4Ω.
Note:
When connecting loudspeakers, it is better to use one pair of output terminals only.
Never connect the “hot” terminals together.

操作注意事项
1. 请确认电源电压与本机相符，由电压不符造成的损坏不在保修的范围。
2. 所有输入输出线连接好之前，请不要通电；通电前请把音量调至最小以防损坏扬声器。
3. 当通电并输入信号后，如果保护指示灯(PROT)点亮，说明有输出短路故障。此时应立即切断电源，
排除故障后再重新通电。
输入连接
所有输入均应连接于机器后面板的卡隆插口（图 1）或 6.35mm 插
口。
输出连接
输出端子在后面板，可用香蕉插或铲形插连接。黑色为公共端，
红色为热端。
通常应使用“定压”(70V、100V)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，此时相应的扬声器的总阻抗应不低于 4Ω。
注意：
只宜选用一对输出端子；
任何时候都不应把两个“热端”连接在一起。
