boosts some frequencies and attenuates others in this way. So graphic equalizers are used, in this context,
to compensate for the "damage" done to the sound by the room itself.
2.) FEEDBACK CONTROL: Without a graphic equalizer, it is quite difficult to stop feedback (that piercing,
whistling sound that happens when microphones pick-up and reamplify the sound from the speakers). A
graphic equalizer can zero in on the offending frequency and reduce it, leaving the rest of the music
unchanged.
3.) CREATIVE RECORDING: Graphic equalizers are routinely used to make certain sounds "brighter" or
"fuller" or even radically different, depending on the creative whims of the operator. A voice can be made to
sound as though it's coming through a telephone line, for example. An acoustic guitar can be given a metallic
sparkle. A kick drum can get more "snap". It may be a cliché, but it's true: With a graphic equalizer, you are
only limited by your own imagination!
OPERATION
Front panel
1. POWER Switch
Turns power to the processor 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.
EQUALIZER SECTION
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. PEQ Faders 1 & 2
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.
4. LED LEVEL Meter
Indicates the level reduction in dB.
5. PROCESSOR RANGE Selector
One of the reasons to use a graphic processor 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.
6. EQ BYPASS Selector
This switch allows instant comparison of the original sound with the equalized sound.
7. LOW CUT Selector
This switch allows you to cut down unwanted low frequencies.
