High headroom analog mastering EQ with proportional Q for exacting performance
The king of parametric EQs
The PQ Mastering Equalizer is a fully parametric, dual-channel five-band equalizer, based on SPL’s pioneering 120V rail technology. Able to switch between constant and proportional Q modes with the push of a button, this kind of circuit has not yet been achieved in any other analog equalizer.
Designed for precision performance
Each of the five bands of the PQ can be independently activated, deactivated, or switched between Constant Q and Proportional Q modes for even more targeted cuts and boosts. Thanks to the “1/4 Gain Switch”, you can reduce the range of the EQ from +/-20 dB down to +/-5 dB cut or boost to easily perform the small corrections common in mastering. And, with the detented potentiometers, precise settings are easy to dial in.
Now improved with plugin-only features

"As an owner of the original hardware SPL PQ, [SPL PQ is] a unit that truly mirrors the original sound - warm and really analog sounding."
Eric Racy
"Generally, EQ plugins are either surgical tools that allow you to fix issues or they are good at “sweetening” and broad stroke enhancement. The PQ manages to allow you to do both and do them incredibly well!"
Joost van den Broek
"This plugin really adds the ultimate parametric EQ to your in-the-box toolkit. Amazing to have this famous master EQ as a plugin now!"
