Low Frequencies (Bass)
Lowest end of the spectrum – frequency range usually between 20 and 150hz.
High Pass Filter used on the low frequencies – removing all the frequency below it’s cutoff point, allowing those above it to ‘pass’ though.
Low Shelf – when applied all frequencies below the cutoff are increased or decreased by adjusting the amount of gain.
Mid Range Frequencies (Middle)
Usually where most instruments live – approximately between the range of 150hz to 4Khz or 4000hz
Band Pass Filter – removal of neighbouring frequencies allowing the desired frequency to pass through.
High Range Frequencies (Treble)
Top top end of the frequency range, usually where the higher pitched instruments live, ie cymbals. Usually the range between 4khz 0r 4000hz and 20khz or 20,000hz
Low Pass Filter – used on the high frequencies – removing all the frequency above it’s cutoff point, allowing those below it it to ‘pass’ though.
High Shelf – when applied all frequencies above the cutoff are increased or decreased by adjusting the amount of gain.
Gain – amount of cut or boost to be applied to frequency range.
Q – The EQ Adjustment value – ‘Q’ adjustments have an affect on the neighbouring frequencies – a broad ‘Q’ seeting will have more of an affect on a wider frequency range, a fine/narrower ‘Q’ setting will hone in on the frequency to be adjusted, with a smaller amout of neighbouring frequencies being affected…
