MASSIVE PASSIVE is a two-channel four-band equalizer added with high pass and low pass filters. By "passive" is meant here that the tone formation in the smart new EQ design does not use any kind of active circuit - it is a bit like a Pultec EQ on hyper-steroids.

The mastering edition

Here the filters are changed and laid a little deeper and higher, so that they better suit a mastering situation. The master gain buttons are in fixed steps with 11 positions with ½ db change per. step.

Natural methods

Creating a natural, organic sound can really only happen by using an EQ, which processes the signal with natural methods. Massive Passive uses simple passive components and utilizes their natural qualities rather than letting a complex circuit force the signal in a certain direction. Compared to other devices, Massive Passive allows you to use much more EQ with much less staining.
