It is an emulation of the classic professional parametric vacuum tube equalizer from 50's and 60's. We programmed the Pultronic EQ-110P equalizer in the way that it can add real and hearable warm, color and dynamics of the vacuum tube devices into your music. Many frequency and amplitude analysis of input and output impulses from real vintage vacuum tubes were used during the development. These impulses were recorded via the real vintage devices which allowed us to achieve the excellent and realistic results. Thanks to this process you can choose from several algorithms which emulate the various vacuum tubes in order to achieve the wide spectrum of the music colors. We put our rich experience with analog electronic devices into the development of this product so the virtual schema of the Pultronic is very similar to the real circuits of the electronic equalizers. The equalizer contains 4 parametric filters: Low frequency cut, Low frequency boost, Middle frequency cut / boost, High frequency boost These equalizing circuits allow you to "sweet" color of the sound as well as softly saturate it and emphasize the bass and treble frequencies. The parameters like Warmth, Saturation and Brilliance can be used to adjust the characteristics of the output amplifying vacuum tubes. The Pultronic equalizer EQ-110P is suitable for recording, tracking and mixing. Don't hesitate to color your digital records with lovely&sweet as well as dirty&warm sound from the beautiful age of 60's !!!
