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.

What is the tube stage doing?

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.

…like a tasteful diffuser does the sound of the tube lay itself over the existing signal and rounds off the overall image…

…Female voices sound gallant and gain presence even without making use of the different filters…

…The result is absolutely convincing. The voice gains more deepness, appears more transparent and special and seems forceful…

…intuitive to handle with an absolutely convincing sound result…

…weather it was vocals, acoustic guitar, completing tracks while mastering,etc the CTE could convince in all disciplines , always sounding warm whilst still transparent…

…very defined and clean, full of volume and still has the tendency to smear the signal during upliftment…

…All in all, the equalizer sounds rather mild and ordinary; even major settings don’t cause great change or exaggeration with the sound…
