Troubleshooting
Situation | Indication | Action |
No Sound | Signal LED not lit | Check AC plug. Confirm that AC outlet works by plugging |
| Clip LEDs not lit | in another device. |
|
|
|
| Signal LED not lit | Make sure the signal source is operating and try another |
|
| cable. Check position of Volume Pots. |
|
|
|
| Signal LEDs responding to signal level | Check the speaker wiring for breaks. |
|
| Try another speaker and cable. |
| Protect LED is lit | Overheating will cause protective muting. Check for |
|
| proper ventilation. |
|
|
|
No Channel | No Channel Separation | Check the mode indicators on the front panel and make |
Separation |
| sure the mode selector on the rear panel is in the two |
|
| channel (stereo) position. Make sure other equipment in |
|
| the signal path such as mixers and preamps are set for |
|
| stereo, not mono |
Distorted Sound | Power LED is lit | A faulty speaker or a loose connection could cause this. |
|
| Check the wiring and try another speaker. |
| Signal LEDs responding to signal level | The signal source might be clipping. Keep the volume |
|
| pots at least halfway up so that the source does not have |
|
| to be overdriven. |
| Clip LEDs not lit | Keep the volume pots at least halfway up and try |
|
| changing input sensitivity with the gain selector on the |
|
| rear. |
Hiss | Hiss | Unplug the amplifier input to confirm that the hiss is |
|
| coming from the source or from a device upstream. Erratic |
|
| or popping noises indicate an electronic fault in the |
|
| offending unit. To keep the noise floor low, operate the |
|
| primary signal source at full level, without clipping. Avoid |
|
| boosting the signal further between the source and the |
|
| amplifier. |
Squeals and | Squeals and Feedback | Microphone feedback should be eliminated with mixer |
Feedback |
| controls. If noise continues to build up with no microphone |
|
| gain, there is a serious fault in the signal processors or |
|
| cables. Working in succession from the signal source |
|
| towards the amplifier and check each device in the signal |
|
| path by reducing its gain or by unplugging it. |
