MQ55 is a parametric mixing equalizer based on MQ57. The difference is that MQ55 operates only in stereo mode, has cut filters with milder slopes and greater operating ranges and gain ratio that acts like dry/wet control.
The MQ57 parametric M/S equalizer is designed for mastering. It has relatively wide Q factors that focus on overall balance rather than narrow cuts and boosts, moderate gain ranges for fine-tuning and functions such as channel linking and precise cut filters.
SX36 is three-band stereo processor capable to separate audio into low, mid and high frequencies and lets you manipulate their stereo properties – width and panning or rotation. It has simple meters for each range showing correlation or panning.
