Troubleshooting
Situation | Action |
No Audio Output | Check AC power - is the power LED on? |
| Check in/out connections - are they reversed? |
| Are you sure you have an input signal? |
EQ Controls Do Nothing | Is the master EQ switch in? |
| The lowest and highest frequency sliders may be beyond the range of the program material |
| or speakers and may produce little, or no audible effect. |
Peak Light Flashes or | If the peak light flashes, the signal level to the equalizer is too high, turn down the gain |
Stays On All the Time | and/or reduce input level to the equalizer. If it is on all the time, disconnect the input and |
| output cables. If it is still on, the unit must be returned for service. |
Distorted Sound | This will only be caused by too much signal, which will show on the Clip LED. If the LED is |
| not flashing, there is an overload somewhere else in the signal path. Adjust the relative gain |
| of each component in your chain to keep everything at a comfortable level. |

Excessive Hum or Noise | Hum will usually be caused by a ground loop between components. Try using the suggested |
| balanced input and output |
| your equalizer have balanced inputs and outputs. Noise (excessive hiss) can be caused by |
| insufficient drive signal. Make sure you are sending a nominal 0 dBu line level signal to the |
| equalizer. Most noise problems occur because gain is applied to audio signals too late in the |
| chain. For best performance, apply gain to individual source signals as early as possible, like |
| at the mixer input section. As gain increases, it also boosts the noise content of that signal. |
| Any cumulative noise built up in a mixed signal will only be increased by using an equalizer |
| as a gain device, so make every attempt to operate the equalizer with as little gain as |
| possible. |
Note: Unshielded cables, improperly wired connections, and cable with broken strands (shorts, etc.) 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.
