SYMPTOM | PROBABLE CAUSE |
1 No power | Check connections to the amplifier's Ground, B+ & Remote |
| terminals. Check connection at "+" terminal of the battery. |
| Check the remote |
| when the source is turned on (or when the switch is turned |
| on). Refer to the Installation Section. Check the power line |
| fuse: if fuse is blown, replace it; if fuse continues to blow, |
| check the power wire and also the amplifier for a short. If the |
| short is in the power wire, fix it; if the short is in the amplifier |
| itself, see your Coustic dealer. |
| Check the voltage at the amplifier, and the remote ON/OFF |

3. Power without sound with | The continuous red light of the power indicator signals a high | |
| red power indicator on | internal operating temperature, which results in the amplifier |
|
| switching off temporarily; when the amplifier cools down to a |
|
| safe level, the amp will automatically restart. |
4. | No sound from one side | Check balance control. |
|
| Check speaker connections. |
|
| Check signal input connection. |
5. Very low sound from | Check your radio's fader control. | |
| both radio & tape | Check the amplifier's Input Sensitivity Level. |
6. | Frequent automatic amplifier | This indicates that the amplifier is operating at a continually |
| shut down | undesirable high internal temperature. |
|
| High operating temperature caused by inadequate ventilation. |
|
| (Refer to the |
|
| location). |
|
| High operating temperature caused by an excessively low |
|
| impedance load, say below 2 ohms. Check for bad speakers |
|
| and/or electronic crossover, proper passive crossover |
|
| components; if all else fails, try rewiring the entire system. |
|
| High operating temperature can be caused by an incorrect |
|
| input sensitivity level (refer to |
|
| SENSITIVITY ADJUSTMENTS for correct setting). |
