EQ Types
Each of the MTK's four EQ bands can be designated as a specific
EQ type that determines the behavior of the band. These are:
•
a parametric or "peaking" EQ—that allows you to target a
specific frequency, called the "center frequency, " and raise
or lower its volume. The Q control determines the range of
frequencies around the center frequency whose volume is
to be affected (the higher the Q setting, the narrower the
range of affected frequencies).
•
a shelving EQ—that allows you to raise or lower all the
frequencies above (high shelf ) or below (low shelf )
a specified frequency. The shelving EQ requires no Q
setting.
•
a filter—that allows you to remove an entire range of
frequencies. There are several ways a filter can work:
•
A low pass filter—removes all frequency content above
a specified "cutoff frequency. " It's called a "low pass"
filter because it lets all frequencies that are lower than
the cutoff frequency pass through unaffected.
•
A high pass filter—removes all frequency content below
a specified cutoff frequency. It's called a "high pass"
filter because it lets all frequencies that are higher than
the cutoff frequency pass through unaffected.
The low and high pass filters don't drastically cut off all frequency content
right at the cutoff frequency—they gradually lower it over a frequency
range called a "slope." In some instances, the slope can be adjusted with
the Q control.
•
A band pass filter—only allows a specified band of
frequencies to pass through unaffected, removing
all other frequency content below and above the
selected band. The Q control determines the width of
the filter band.
•
A band eliminate filter—removes a specified band of
frequencies. The Q control determines the width of the
filter band.
Selecting the EQ Type
To choose the EQ type for each band, set FREQ (Hz)—TYPE so
its indicator is lit. Using the selection boxes under the first row
of onscreen knobs, you can assign each band to function as
one of the following EQ types:
•
PEAK—Peaking EQ.
•
LSV—Low shelving EQ.
•
HSV—High shelving EQ.
•
LPF1—Low pass filter with a fixed gentle slope.
•
LPF2—Low pass filter with an adjustable slope.
•
HPF1—High pass filter with a fixed gentle slope.
•
HPF2—High pass filter with an adjustable slope.
•
BPF—Band pass filter.
•
BEF—Band eliminate filter.
•
THRU—Bypasses the EQ band.
For most mastering applications, a good starting point is to set the EQ
types as follows: Band 1-LSV, Band 2-PEAK, Band 3-PEAK, and Band 4-
HSV. However, don't be afraid to experiment to find the types that work
best for you.
