Do I really need that steering wheel on my car, or can I just buy it later? It seems like a silly question, doesn’t it?
But do you have a 31-band graphic equalizer in your sound system? If you don’t, I’m certain that you’re unhappy with your sound.
Additionally, if you do have a graphic EQ and it’s not properly set, I’m equally certain that your sound is not what it should be.
A graphic EQ is LITERALLY the steering wheel on your audio system. (Please bear in mind the EQ is only one of several audio management components that are frequently utilized, so we’ll limit this discussion to EQ, as it is probably the most crucial.)
When you listen to sound directly from the source, without a sound system, it is perfect unto itself. It is what it is.
Many times when we put sound through a system, the resultant sound isn’t represented at all like the original sound. The sound may be thick or thin, hollow or piercing, and feedback and lingering overtones can drive you crazy. (Those of you without equalizers are now nodding your heads emphatically in agreement).
Every acoustic environment will affect the sound that emanates from your loudspeakers, and in many cases the loudspeakers themselves are coloring the sound as well.
Cup your hands, closed, in front of your mouth and say “Hi…how are you today?” It sounds awful, doesn’t it? We call this a lack of transparency.
Now remove your hands from in front of your face and say it again. It sounds exactly like you, doesn’t it? We call this perfect transparency, and that is what we attempt to achieve with the use of an equalizer.
I say “attempt” because perfection is almost always unattainable, but we can get very close.
Now let’s talk about rooms. Every room in America is built of pretty much the same types of construction materials. We all tend to use concrete and brick, gypboard and glass, carpet and tile, wood and draperies—you get the idea.
