Equalizer (EQ)
Many audio signals coming into the console require some degree of corrective EQ in order
to be part of a good-sounding mix. The X 18R & X 20R offer a very useful and great-sound-
ing EQ section on each channel. The input EQ consists of four bands: High, High-mid, Low-
mid and Low. The High and Low frequency bands each have a boost/cut control and their fre-
quencies are fixed. The High-mid and Low-mid bands each have variable boost/cut along with
tunable frequency.
