Operation - Omnitronic GEQ-231 FD Mode D'emploi

OPERATION

Front panel
1. POWER Switch - Turns power to the equalizer on and off. Be sure to power-up before your power
amplifier is turned on to avoid loud transients which could damage your speakers or annoy your audience.
2. FREQUENCY Faders - Move these sliders upwards to boost a specific frequency. Move them downwards
cut (decrease) them. When moving these controls past zero, you will feel the center-detent (notch) in the
control which makes it very easy to find zero in a hurry, or even in the dark.
3. LED Level-Meter / FEEDBACK LEDs - Let(s) you keep an eye on the signal level in order to avoid
distortion.
4. EQUALIZER RANGE Selector - One of the reasons to use a graphic equalizer is that the frequency
sliders themselves form a graphic depiction of the frequency response curve you have set. But if your
settings are very subtle, the "graph" becomes difficult to set and see. If you encounter this difficulty, simply
push this Range Selector Switch. You can reduce the maximum boost/cut range of the frequency sliders
from 15 dB to 6 dB and make your adjustments, taking advantage of the greater fader travel necessary to
get the same amount of hoost or cut.
5. THRESHOLD Control - Adjusts the threshold value of the Feedback LEDs.
6. FILTER Selector - This switch activates the filters.
7. EQ BYPASS Selector - This switch allows instant comparison of the original sound with the equalized
sound.
8. LOW CUT Control - Allows you to determine the lower cutoff frequency. The high pass filter can be set
from 10 to 400 Hz. Use this filter as a tool to limit the frequency frange to be processed.
9. HI CUT Control - Allows you to adjut the upper cutoff frequency. The low pass filter can be set from 4 to
30 kHz. Use this filter as a tool to limit the frequency frange to be processed.
10. LEVEL CONTROL - To adjust the output level.
If a frequency range is highly boosted, the output level needs to be reduced via the level-control in order to
avoid amplifier distorsion.
