Parameter Setup – EQ (Pro)
As you may have noticed, the remaining dynamics are book marked between the input and output meters.
We will get to the gate, comp, and de-esser shortly, but we’re going to start with the EQ.
Let’s take a look at the five EQ bands to see how they function. Before that, though, take a quick peek in the upper-lef
corner of the M-VOICE popover. Notice the switch there? This switch allows for true bypass of the EQ circuitry to ensure
that there is no coloration of the signal if the EQ is not needed. When this switch is disengaged, the EQ controls have
no eect on the signal. You may use this switch to make an A/B comparison between the EQ’d signal and the signal
without EQ. Click on this switch to turn EQ on or o. It will illuminate green when engaged and is gray when disengaged.
EQ Gain, Frequency, Q [Bandwidth], and Shelf/Bell
The gain and frequency may be changed by utilizing the mouse to tap-and-drag any of the five balls (representing each band)
until the desired sound has been achieved. Moving a ball vertically changes the gain by up to ±24 dB. Moving a ball horizontally
changes the frequency, ranging from 20 Hz to 20 kHz.
While the entire frequency range is 20 Hz to 20 kHz, each EQ band has its own range.
This will be discussed shortly.
Q [bandwidth] ranges from 0. – 20.0. A smaller Q value results in a wider
curve, while a larger Q value results in a narrower curve where frequencies
may be zoomed in on more precisely. A smaller Q is generally intended
for more musical purposes, while a larger Q is generally used when
decreasing problem frequencies.
The Q may be changed in one of two ways. Either () hover over the EQ band’s
ball and scroll the wheel up or down to change the Q, or (2) mouse click
on the band to reveal a popover as seen to the right. From here the Q
(i.e. “Width”) may be raised/lowered via the mouse wheel or mouse-click-hold
while simultaneously moving the mouse up (increase Q) or down (decrease Q).
Want to learn more about Q? Ok, let’s nerd out together!
Although the Q control does adjust the bandwidth of a filter, the Q value itself is dimensionless; it has no unit
of measurement. Some equalizers use the fractional bandwidth of the filter, measured in octaves, to express
this parameter. The two parameters are inversely related; a high Q value corresponds to a small fractional
bandwidth. The following table lists some equivalent Q and fractional bandwidth values.
Q BW (oct) Q BW (oct)
0.7 2 2.87 /2
.44 4.38 /3
2.45 2/3 5 /0
