The dbx graphic equalizers are useful audio signal processing tools in situations where precise frequency

control is required across the audible frequency spectrum.

When used with an audio spectrum analyzer the EQs can tune any acoustical environment - from the stu-

dio to the concert hall- to stop ringing, increase clarity, and flatten the overall frequency response of the

environment. A real time audio spectrum analyzer or other types of audio environment analyzers are

very useful in determining the amount of equalization needed.

Insert the graphic equalizer between the signal source (usually a mixer) and the power amplifiers to the

speakers (or the crossover if there is one). Adjust the level and equalization as required to yield the

desired system response. The long throw sliders of the EQs allow very precise settings of the equaliza-

tion for accurate equalization curves.

A very similar set-up is used for portable sound reinforcement systems. The EQs are especially useful to

eliminate feedback from stage rumble, poorly placed microphones, or wind noise, notching out the

offending frequencies. Stage rumble is easily taken care of with LOW CUT filter control. The equalizer

can also help to make up for some sound system deficiencies in frequency response.

In the studio, the EQs are very useful in modifying and enhancing audio signals. Route the signal to the

equalizer and then return it to the mixing board after modification to be mixed with other signals or

processed further. Comparison of the equalized signal with the unprocessed signal is performed with the

IN/OUT switch.
