Equalizer (EQ)? You may find it on some mini hi-fi. The most basic one can be "tone" or "bass, treble, mid" adjustments. Hence, an equalizer serves as a device that changes the characteristic of a sound.
There are quite a number of them, from the smallest basic treble-bass that kind, to the 32 bands frequencies wide range graphic EQ, and to the most sophisticated parametric EQ.
Why change the sound characteristic? Isn't that original sound is the most important? The most expensive amplifier gets the most original sound, right?
Actually, in my personal view, original sound is important, but when playing in a band/orchestration, some frequencies can be eliminated to ensures the clarity of every instrument. For example, when u boost 100Hz for the kick drum, you may as well want to decrease the 100Hz of the bass guitar while boosting it at maybe 250Hz (its very own place in the wide frequency spectrum) . This is to ensure that they don't overshadow each other. Ensures clarity!
People usually likes to make a "smile" face on the graphic EQ on their home system, this is due to a psychoacoustic effect on human's brain. Our ear tends to accept and translate sound level in a non-linear scale. Meaning, while you hear the midrange frequency doubled its "loudness", it doesn't mean that your brain takes bass (same power of boost) as doubled loudness. Usually we are weaker at the bass and treble response at low volume, hence we tends to boost them up in everyday consumer hi-fi. But in live music where the SPL raise till a significant loudness, things become different. EQ is then used for the clarity and the feedback control. If used wrongly (if overboost), it may cause distortion. Distortion destroys speakers.
Still, original sound will be the most important thing.
Yet, how come... Perhaps a room having weak acoustic don't meant to be mixed nicely? But, when i play CD on it, it sounds just fine, just a little bit muddy/draggy.. How to mix in a semi mic in room? How to mix if there is some instrument that just doesn't need nor can be mic in? How to compensate? Any idea?
