Mastering Effect - Roland MC-909 Owner's Manual

Mastering effect

This is a stereo compressor (limiter) that is applied to the final
output of the MC-909. It has independent high, mid, and low ranges.
By compressing sounds that exceed the specified volume level, it can
be used to prevent the sound from distorting.
