Stereo EQ

The Stereo Input channel has two parallel EQ circuits that are controlled by the same set of knobs. It is functionally identical to the Mono Input EQ.

Many audio signals coming into the console require some degree of corrective eq in order to be 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.
