EQ550 Discrete 5 Band Equalizer (VST, AU,AAX Plug-in) Free License

Posted by

EQ550 from Overloud is a plugin modeled after a famous classic American equalizer(EQ). This EQ has a unique proportional cue whereas the gain of the filter increases, its bandwidth becomes proportionally narrower.

Just like the rest of Overloud Gem Series, EQ550 recreates the sound of the original analog hardware while expanding upon its original features.

First, it has five total bands instead of three, next it offers continuous controls where the original has discrete knob positions.Each band also has a cue button which solos that specific band so you can hear the exact frequency at which the filter is working.

The high and low bands can be switched between peak and shelf modes, in shelf mode, the filter boosts or cuts everything beyond the selected frequency.

becomes narrow when the gain of the filter increases. For low gain settings, the EQ delivers a smoother tone: its character becomes more and more aggressive when the bands gain band is
