Logic Pro Legacy Fat EQ
Fat EQ is a versatile multiband EQ that can be used on individual sources or overall mixes.
Fat EQ provides up to five individual frequency bands, graphically displays EQ curves, and
includes a set of parameters for each band.
Fat EQ parameters
• Band Type buttons: For bands 1, 2, 4, and 5, click one of the paired buttons to select
the EQ type. Band 3 is parametric.
• Band 1: Click the highpass or low shelving button.
• Band 2: Click the low shelving or parametric button.
• Band 3: Always acts as a parametric EQ band.
• Band 4: Click the parametric or high shelving button.
• Band 5: Click the high shelving or lowpass button.
• Graphic display: Shows the EQ curve of each frequency band. The scale is shown in dB.
• Frequency fields: Set the frequency for each band.
• Gain knobs and fields: Set the amount of gain for each band.
• Q fields: Set the Q or bandwidth of each band—the range of frequencies around
the center frequency that are altered. At low Q factor values, the EQ covers a wider
frequency range. At high Q values, the effect of the EQ band is limited to a narrow
frequency range. The Q value can significantly influence how audible your changes
are—if you are working with a narrow frequency band, you usually need to cut or
boost more drastically to notice the difference.
Note: For bands 1 and 5, this changes the slope of the filter.
• Band On/Off buttons: Turn the corresponding band on or off.
• Master Gain slider and field: Set the overall output level of the signal. Use it after
boosting or cutting individual frequency bands.
