sculpting. The four-band EQ has been designed to
be flexible enough to cover a broad range of
applications. By adjusting Gain and Bandwidth
together, you can emulate the smooth and musical
character of classic analog EQ circuits, in which the
Gain/Bandwidth dependency was dictated by the
actual circuit design and electrical components
used.
Low and high shelf filters
The Low and High bands offer a shelf option that is
similar to those found in most conventional
parametric EQs.
EQ graph
The EQ graph below the EQ section (Figure 8-3)
provides a thumbnail visual indication of the
current EQ settings for the input channel. It is for
visual reference only and cannot be edited directly.
However, you can click it to open the full-size EQ
graph in a separate window (Figure 8-4), which is
fully editable.
COMPRESSOR
All mixer input channel strips provide a
compressor module.
Figure 8-5: The Compressor module.
The Compressor (Figure 8-5) lowers the level of the
input when amplitude of the signal is above the
Threshold. The amount of attenuation is
determined by the Ratio and the input level. For
example, if the input is 6 dB above the Threshold
and the Ratio is 3:1, the compressor will attenuate
