IK Multimedia T-RACKS EQ P50B Based on the API Series [download]

Following in the footsteps of its simpler three band P50A brother, the EQ P50B module expands in flexibility by adding a fourth EQ band.

This module is so great sounding because of the rather simple all-discrete circuit schematic of the original hardware it's based on, whose key point is the 2520 op-amp.

Its four peaking bands with seven selected frequencies cover the whole spectrum and then some.

It also allows for the overlapping of bands for complex EQ shapes — this is invaluable in mixing sessions where the proper EQ is the key to finding the right balance and position of a track within a mix.

Simplicity, though, doesn't mean lack of tone: the EQ P50B doesn't have many of the bell and whistle features others offer — like complex and eye-catching but oftentimes distracting displays.

The ease of use of its two knobs per band enhances the analog feel of the module by providing the instant gratification of turning a knob and hearing a result.
