Troubleshooting guide
What might appear to be a malfunction in your unit may just be the result of slight misoperation or miswiring. Before calling service, first check the following table for possible problems.
| PROBLEM | POSSIBLE CAUSE | SOLUTION | ||

| <Protection function>. | |
| (Blown fuse.) | • Replace the fuse and use lower volume. | |||
| • The speaker cord is shorted. | • After check the speaker cord and fixing the | |||

故障检修
有时被认为是故障的现象，其实是因微小的操作或配线失误而造成。 在要求维修之前，请参照下表稍做检查为盼。现象 | 原因 | 排除方法 |
| 没有声音 | · 输入（或输出）缆线未连接。 | · 连接输入（或输出）缆线。 |
| （保险丝跳断） | · 保护线路可能被触发。 | · 参考 <保护功能> 一节，检查连接状况。 |
| · 音量过大。 | · 请更换保险丝，减小音量。 |
| · 扬声器电线短路。 | · 确认扬声器线，解除短路原因后，更换保险丝。 |
| 输出电平过低（或过高） | · 输入灵敏度调节不当，没有位于妥当位置。 | · 调节该控制器。请参考 <控制>。 |
| 声音质量很差 | · 扬声器缆线的极性ª/·连接错误。 | · 请将缆线的极性ª/·连接正确。 |
| （声音失真） | · 扬声器缆线的一根被车体螺钉压迫。 | · 重新连接缆线，使之不再受螺钉压迫。 |
| · 开关的设定可能不妥。 | · 请参考 <系统配置实例>，将开关正确设置。 |

This is a 4 channel amplifier including 2 stereo amplifiers in a body. One amplifier is referred to as amplifier A and the other is amplifier B. This unit is compatible with a large variety of systems by combining the switches and functions described in the following.
1Fuse (25 A x 2)NOTE
If you can’t find the specified capacity fuse at your store etc., consult your Kenwood dealer.
2Battery terminal (POWER IN BATT.)3Ground terminal (GND)4Power control terminal (P.CON)Controls the unit ON/OFF.NOTE
Controls the unit power. Be sure to connect it with all the systems.5Speaker output terminals (A.ch/ B.ch)• Stereo Connections:When you wish to use the unit as a stereo amplifier, stereo connections are used. The speakers to be connected should have an impedance of 2Ω or greater. When multiple speakers are to be connected, ensure that the combined impedance is 2Ω or greater for each channel.
When you wish to use the unit as a high- output amplifier, bridged connections are used. (Make connections to the LEFT channel ªand the RIGHT channel · SPEAKER OUTPUT terminals.)
The speakers to be connected should have an impedance of 4Ω or greater. When multiple speakers are to be connected, ensure that the combined impedance is 4Ω or greater.
6FILTER switch (B.ch)This switch allow filtering of the speaker output signals.•LPFThe filter outputs the band of lower frequencies than the frequency set with the "LPF FREQUENCY" control.
•OFF position:The entire bandwidth is output without filtering.7FILTER switch (A.ch)This switch allow filtering of the speaker output signals.
