Troubleshooting
Situation | Action |
No Sound | Check the AC power. Is the power switch on and the |
| level meters. If they are operating, either the problem is between the mixer and the later |
| components in the system. If there is no meter activity, check to see you really have an input |
| signal and that it is on the desired channel. Check that you have the master gain controls at |
| the desired operating level. |
Distorted Sound | Something is being overdriven in the signal path. If the clip indicators are active, reduce the |
| channel gain controls and/or press in the pad switch on the rear panel. If the level meters are |
| constantly in the red, reduce the Master gain and increase the gain of components following |
| the mixer. There are many gain adjustments in the mixer itself and probably several others in |
| other system components which makes it possible to overdrive an input section and then |
| incorrectly try to reduce the gain of the output section. The best way to approach setting |
| gains is to establish the operating level of input stages first by setting their gain as high as |
| possible but leaving about 20dB of headroom for loud peaks, then move on to set the master |
| gain to produce a good meter reading. Proceed to set the gain of equalizers, limiters, |
| crossovers, and amplifiers following the mixer in the same manner, always working toward |
| the later stages of the system. |
Excessive Noise | If the noise is in the form of hiss, the problem is usually due to an input stage set up for low |
| gain and then compensating by increasing the master gain. Check that the Pad switch is not |
| enabled unnecessarily. Turn up the channel gain controls and reduce the master gain. |
Excessive Hum or Noise | This is usually caused by "ground loops" in the system wiring. A complex sound system with |
| many sources separated by significant distance and using several power outlets has many |
| opportunities for this problem to occur. If possible, feed everything in the system from one |
| power source with a common ground. Use balanced input and output connections between |
| widely separated components. |
Note: Unshielded cables, improperly wired connections, and cable with broken strands are the most common problems. Make sure you use good quality cable with connectors soldered firmly on the correct pin. When in doubt, get in touch with your Ashly dealer.
