EQ: Parametric effect provides maximum control over tonal equalization. Unlike

the graphic equalizer, which provides a fixed number of frequencies

and Q bandwidths, the parametric equalizer gives you total control

over frequency, Q, and gain settings. For example, you can simultaneously

reduce a small range of frequencies centered around 1000&#160;Hz,

boost a broad low‑frequency shelf starting around 80 Hz, and insert

a 60-Hz notch filter.</p>

of this effect to quickly apply preset equalization curves. Use

the advanced version to precisely adjust such curves.</div></div>
