The Premium Tube Series is made up of three individual effects – Passive EQ, Vari Comp and Enhanced EQ – available either individually or as a bundle.

Passive EQ is a fully-parametric, two-channel, four-band equalizer, with additional high and low pass filters plus a wide collection of presets for all use cases. Characterized by its versatile nature and natural sound, it is well suited to a wide range of production duties – from individual tracks to sub groups and even mastering. As with all the effects in the series, running as an individual plug-in in any DAW gives it significant ease-of-use advantages over hardware units, such as built-in parallel processing options, and mid/side mode.
