The Parametric EQ Programs
Two Parametric EQ programs are located in Bank 9.
The Stereo Parametric EQ program provides a two
band stereo, or dual mono, parametric equalizer. The
Mono Parametric EQ program provides a 4-Band mon-
aural parametric equalizer. Both programs provide
frequency adjustment on each band between 30 Hz
and 17 kHz, boost/cut +12 dB, and Q adjustable
between Shelf and 7. In addition, the low frequency
filters provide a Notch (Q=32) with a boost/cut of 36 dB.
Coarse and fine level control, panning (stereo only)
and fine frequency adjustment are also provided. Both
programs operate entirely in the digital domain.
About the Stereo Parametric EQ Parameters
Page One
LVL (Stereo Level)
LVL is a stereo level control, with both channels equally
attenuated or boosted. From -12 to +12 the slider
moves in .25 dB increments. Below -12 it moves in
.50dB increments. Below -60 dB calibration is in larger
steps, finally dropping to zero output at -72 dB.
FIN (Fine Level)
FIN is identical to LVL, but has a range of + 3.5 dB in
reference to the LVL setting. This allows fine adjust-
ment of the level while the mix is proceeding without
fear of over or undershooting the desired setting.
Note: LVL and FIN provide proper scaling for the filters.
For example, if you set a 12 dB boost at some fre-
quency, it is possible to exceed the dynamic range of
the 480L if a high level signal comes in at the center
frequency you have chosen to boost. You can reduce
the drive to the filter with the level controls to prevent
overload.
BAL (Balance)
BAL implements a sine/cosine balance adjustment.
Balance is smoothly adjusted over a wide range, with
excellent resolution in the critical area around zero.
The display indicates the actual channel gain as the
control is varied.
LNK (Stereo Link)
LNK synchronizes the left and right channel settings of
the level, Q, and frequency sliders. When LNK is on,
only the left channel sliders on Page Two and Page
Three are active. When LNK is turned off, independent
control of left and right channel settings is established.
This is particularly useful in mastering applications.
FIN
FIN FREQ L and FINE FREQ R provide fine frequency
adjustment of the Page Two filters by adding a small
amount to their respective frequency settings. (They
set the frequency only for the Page Two filters.) These
settings are particularly useful for fine tuning of notch
filters.
