The Passive-Active Pack from Softube features three very different equalizer plug-ins, each with a distinct character and modeled after real workhorse equalizers, used on thousands of recordings from past to present. Despite the appearance of limitation due to the use of only three bands of EQ, the design and frequency choices have been carefully thought out to deliver musical results.

The Passive Equalizer is a three-band EQ with a clear and open sound, a warm low end, and sparkling top. The Active Equalizer features three fully parametric bands for a tight and focused sound, a great complement to the Passive EQ. The Focusing Equalizer is a non-traditional take on EQ where the low-, mid- and high-bands move automatically and musically in relation to the high- and low-cut filters. It also features filters from the Passive and Active EQ's, as well as a one-knob Saturation control.
