Official description
Passive-Bass:

This is a passive EQ with only Bass Boost. One bell and one shelving band only boost.

Both bands are based on custom-made Inductors with an discret OpAmp for the gain.

There are two options for the discret OpAmp. The first is a more modern designe and the second is a more vintage, very simple designe with much more harmonics.
