EQ and filters
Effects reference
Use EQ to make a sound fit the instrument and listening system. Cutting a troublesome band often leaves more headroom than boosting other bands around it.
| Effect | Purpose and controls | Starting point |
|---|---|---|
| Low/High Pass Filter | Frequency filtering with two High Freq and two Low Freq controls in separate positions. | Adjust one cutoff at a time while listening for the part of the spectrum it removes. Keep other controls unchanged until its action is clear. |
| Baxandall | Broad Bass and Treble shaping. | Begin near the middle of each displayed range; adjust one control at a time. |
| Bi-Quad Filter | Frequency-focused filtering with Freq. | Sweep Freq slowly while playing to find a useful emphasis or cut. |
| 4-Band EQ | Four level bands with individual Bandwidth controls. The displayed level labels include Low Cut, Level 2, Level 3 and High Cut. | Start the level bands at neutral, make a small cut in one band and adjust its width. |
| 11-Band Graphic EQ | Frequency-band levels from the low end through 16k, with Low Cut and High Cut labels at the ends. | Start flat and make a small cut in the band nearest an unwanted resonance. |
| 11-Band Parametric EQ | Band levels plus Q controls that adjust band width/selectivity. | Start with a small level adjustment and a broad band; narrow it only when targeting a specific resonance. |
Some labels repeat or abbreviate the affected band. Use the control's position and displayed value to distinguish it, and compare with bypass after each change.
