Operator Manual – GQX Series Equalizers

Situation

No Audio Output

EQ Controls Do Nothing

Peak Light Flashes or

Stays On All the Time

Distorted Sound

Excessive Hum or Noise

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.

Action

Check AC power - is the power LED on?

Check in/out connections - are they reversed?

Are you sure you have an input signal?

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.

If the peak light flashes, the signal level to the equalizer is too high. Turn down the gain. 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.

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.

Hum will usually be caused by a ground loop between components. Try using the suggested

balanced input and output hook-ups if the other pieces of equipment used in conjunction with

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.
