Creating a Equalization Curve
Adjustable frequency bands and the effect of level
adjustment
63 Hz: Lowering the level will cut the ventilation noise of a
music hall, hum of electronic instruments, boomy bass,
etc.
Raising the level will reinforce the heavy bass part of a
pipe organ or add depth to the bass sound.
160 Hz: Boosting or cutting the normal bass.
400 Hz: Increasing or decreasing the power, spaciousness
and warmth of the sound.
1 kHz: Providing more presence for vocals,'and moving
the sound forward or into the background.
2.5 kHz: Lowering the level will reduce stridency, and
raising will make the base sound brighter.
6.3 kHz: Increasing or decreasing the brightness of the
sound; for example, raising the level will make the violin
sound silky smooth.
16 kHz: Changing the general atmosphere rather than the
sound itself.
Raising the level will highlight the delicate quality of
instrumental sound, and lowering will reduce high-
frequency noise such as the resonant peak of a cartridge,
tape hiss. etc.
