About the Mono Parametric EQ Parameters
Page One
LVL (Level)
LVL is a mono level control, 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 480 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.
FIN
FIN FREQ 1 and 2 provide fine frequency adjustment
of the Page Two filters by adding a small amount to
their respective frequency settings. (They set the fre-
quency only for the Page Two filters.) These settings
are particularly useful for fine tuning of notch filters.
Page Two
FR-1 LF
This control sets the frequency to be adjusted for the
Low Frequency band. Frequency settings fall between
30 Hz and 17 kHz.
Q
Q adjusts the amount of bandwidth affected by the level
control. The Q is determined by dividing the center
frequency by the bandwidth to be affected (in Hz.). For
example, if a frequency of 1000 Hz is selected, and the
bandwidth to be boosted or cut is 500 Hz, the Q = 2. The
Page Two filters provide a Q adjustment from shelf to

Notch (Q=16 or Q=32) The Shelf (SL) on Page Two
filters is a low frequency shelf. This means that with a
frequency of 500 Hz, a level of +12 dB and Shelf (SL)
selected, frequencies below approximately 300 Hz will
be boosted by 12 dB and 500 Hz will be boosted
approximately +9 dB. The Notch feature is found only
on the Page Two filters and is optimized for low
frequencies.
LEV
LEV provides level boost or cut at the defined fre-
quency and Q settings. LVL is adjustable between -12
to +12 db when the Q setting falls between shelf and Q
= 7. When a Notch Q is selected (Q=16 or Q=32), LVL
is adjustable between -36 and +36 dB. This only
applies to the Page Two filters.
FR-LM
This control sets the frequency to be adjusted for the
Low-Mid Frequency band. Frequency settings fall be-
tween 30 Hz and 17 kHz.
Page Three
FR-HM
This control sets the frequency to be adjusted for the
High-Mid Frequency band. Frequency settings fall
between 30 Hz and 17 kHz.
Q
The Page Three filters provide a Q adjustment from
shelf to Q = 7. The filters on Page Three have a high
frequency shelf that boosts all frequencies above the
set frequency. This is identified by "SH" in the Q
display.
LEV
LEV provides level boost or cut at the defined fre-
quency and Q settings. LVL is adjustable between -12
to +12 db.
FR-HI
This control sets the frequency to be adjusted for the
High Frequency band. Frequency settings fall be-
tween 30 Hz and 17 kHz.
