Audio Control Octave
Stereo Graphic Equaliser
The four bottom sliders on your Octave graphic equalizer roughly correspond to the bass control on your amp or receiver; or rather we should say that your receiver's bass tone control is what's rough.
31.5 Hz - Truly a piece of the rock. This lowest of lows is what you've always wanted more of. It's the frequency that you feel as well as hear. The frequency that kicks you at live concerts.
63Hz - Here's the bass you were after when you used to turn on the loudness or bass tone control. It's the deep, tight, strong bass that makes rock solid and disco kick.
125Hz - This is the bass that jukeboxes and cheap stereos specialize in. It has a boom quality that can get very tiresome to the ears after a while. That's not to knock it. Push the 125Hz slider to minus 5dB and you'll find a lot of what you might have thought was bass will be gone.
500, 1000, 2000, 4000Hz - These sliders control the core of music. Melody instruments, vocals, midrange percussion - almost everything we associate with music. With care, you can substantially change the sound of most melody instruments as well as vocals. Each cut and album will be different, so experiment.
8000 and 16000Hz - Oddly enough, neither of these frequencies is as ear-piercing as you might think. What, you thought was tinny treble is really lower down at 2000 and 4000. Up at 2000 you'll be surprised how few instruments are actually affected. The tips of womens' vocals, snare drums, some synthesizer and higher brass and woodwinds. But you can use more of it than you might first suppose by its classification as treble.
As for the 16KHz, well, it's the icing on that audio cake we were describing earlier. The crisp sizzling of cymbals, the high harmonic overtones that bring music to life; they're all here.
