Classic Equalizer EQP-1 – Passive Tube Equalizer

Classic Equalizer EQP-1 – Passive Tube Equalizer


Did you ever hear such heighs with a software-EQ?

I think not!

With this EQ, you turn in highs and bass and it sounds just as good as you expected it. Even better. You will be astonished and ask yourself how you have ever managed without the Classic Equalizer. You constantly thought after every Plug-in that you tried that it could work better. You knew it and now you have found it! Get the Classic Equalizer and gain the experience.

Even though there are major advances within the digital-technique during the past years, good sounding equalizers are still a domain of analogue devices.
And, who heard the Classic Equalizer once, knows why: voices sound silky, instruments step out of the mix and are clearly locatable without one turning them up.
Deep-frequency instruments, like bass and bass-drum get the necessary push without sounding jittery. If you lift up the highs, it does not sound like lifted highs but it simply sounds fresh.

The Classic Equalizer EQP-1 was built after the model of classic vintage equalizers with passive components (condenser and inductor) in the EQ-section which accounts for its special sound.

The EQP-1 consists of three parts: bass boost and attenuation, treble boost with adjustable bandwidth and high frequency attenuation.


The Classic Equailzer equiped with a tube stage and high quality input and output transformers.

Beside the open and airy sound of the equalizer the signal will get more density and additional presence by the tube and the transformers. The low end becomes more transparent and defined. The highs will sond more rounded and pleasant to the ears.
This effect will already take place as soon as the device is in the signal path, even if the equalizer is not used.
