EQ

St Hi-Lo Shelf

This is a stereo-input, stereo-output two-band EQ, with high and low shelving. As
with all EQs in the OASYS PCI, the curves are smooth and symmetrical in
frequency, modeling analog EQs.
For the more technically inclined, the EQ calculations are all double-precision,
using first-order error-feedback.
Input
Level
-INF, -69.0 to 0.0dB. This sets the input level for the effect. It does not affect the dry
signal.
Note that extreme positive or negative gain settings can dramatically increase the
volume within the EQ effect, so it may be necessary to decrease the input volume to
avoid clipping.
Low Shelf
Frequency
20-2000Hz. This sets the cutoff frequency of the low shelving EQ, in Hz. This is the
point at which gain is 3dB below maximum, as shown in the figure "High and Low
Shelving EQ," on page 404.
Gain
+/-18.1dB. This sets the amount of boost or cut for the low shelf.
High Shelf
Frequency
5000-20000Hz. This sets the cutoff frequency of the high shelving EQ, in Hz. This is
the point at which gain is 3dB below maximum, as shown below.
Gain
+/-18.1dB. This sets the amount of boost or cut for the high shelf.
