EQ
Many audio signals coming into the console require some degree of corrective eq
in order to be part of a good sounding mix. XR-20 & XR-24 offer a very useful
and great sounding 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 frequencies are fixed. The High-mid and Low-
mid bands each have variable boost/cut and variable frequency.
