The Magic Knobs Called Mid-Sweep

The function of an equalizer is to attenuate (make louder or softer) frequencies. For example if you increase the high frequencies (treble) the sound will become brighter. Most small mixers, even the cheap ones nowadays, have 4 knobs in the eQ section of every channel. For some of us only the top and bottom knob has any effect on the sound. The second and third knob don't seem to function. Please refer to the picture below.
If you have tried turning these knobs and they don't seem to have any effect, you could be using them wrongly. The second and third knobs are usually the mid-sweep section of the eQ. This means that one of the knobs is used to attenuate (increase or decrease volume) while the other is to select a frequency. Therefore if you are selecting a frequency using the third knob while the second knob is 12 o'clock (no attenuation is applied), then there will be no audible change in the sound. Please refer to your mixer manual to be sure or send me an e-mail.
Why do I call this the magic knob? The ability to select a particular frequency to attenuate opens up a whole new world. You could cut microphone feedback on the fly and select the sweet frequencies of a source. I'll touch on cutting feedback on my next tip.
