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 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.

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.
