Equalizer (EQ)

part of a good sounding mix. XRM offers a 4-Band EQ on each channel.The input EQ consists of
the bands: High, High-Mid, Low-Mid and Low.The High and Low frequency bands are shelving
equalizers, each have a boost/cut control and their frequencies are fixed.The High-Mid and Low-
Mid bands have a bell-shaped response, each band features variable boost/cut and adjustable fre-
quency.
