TROUBLESHOOTING TIPS

8.1

No Audio Output

Check AC power - is the pilot light on?

Check in/out connections - are they reversed?

Are you sure you have an input signal?

8.2

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 ef-

fect.

8.3

Peak Light Flashes or Stays On All the Time

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.

8.4

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 be-

tween components. Try using the suggested bal-

anced 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 insuffi-

cient drive signal. Make sure you are sending a

nominal 0 dBu line level signal to the equalizer.

Most noise problems occur because gain is ap-

plied 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 in-

put 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 con-

nections, and cable with broken strands (shorts,

etc.) are the most common problems. Make sure

you use good quality cable with connectors sol-

dered firmly on the correct pin. When in doubt,

get in touch with your Ashly dealer, or call the

Ashly service department at 800-828-6308.
