the same as simply raising the volume level. In this case, do the
following:
1 ) With the instrument playing, start by boosting 3 sliders
at a time until the offending frequency area is found. (If
the
Clip LED should light, turn down the Input control)
2 ) Now, decrease the sliders until you are cutting the level
instead of boosting.
3 ) Experiment with the amount of decrease of the adjacent
sliders as in feedback control (see Figure 4B).
PLEASE NOTE:
The M-EQ 230 (and all other graphic Equalizers) will sound best when the
sliders show a gradual slope rather than a few wild boosts or cuts (See Figure
4A and 4B).
Since the M-EQ 230 can be used with any electric instrument or
microphone requiring tonal alteration, here are some generic
suggestions as to setup. Since each instrument will sound
different due to the uniqueness of the instrument itself, the type of
music being played, the arrangement, and the touch of the player,
you must use your ears (and the chart below) to ultimately find the
correct settings.
