RUBY 2 is a VST/AAX/AU plug-in which faithfully replicates the operational mode and classy sonic imprint of the highly prized VT-5 vacuum-tube equalizer built by D.W. Fearn. The VT-5 has been lovingly conceived, perfected, designed and finally produced by D.W. Fearn as a result of his long-standing experience as a recording engineer/audio designer who is used to working with the best existing audio processors.
Over the years D.W. Fearn has come to know the sound he’s after like the back of his hand: because of this, the task of producing a convincing digital replica of his processors has proven to be an impossible mission for a long time. Several past attempts have been discarded by the man himself, just because he felt there was something lacking in the various proposed digital emulations, so much that he didn’t feel confident enough as to put his brand name (and his credibility) on those half-baked efforts.
It took Acustica Audio’s proprietary sampling technology to finally succeed in the difficult task of appeasing D.W. Fearn; only RUBY 2 could convince him to release a digital replica of his stellar equalizer in a plug-in format with his name on it.
Ruby is as an official endorsement and a faithful representation of the D.W. Fearn highly sought-after vacuum tube equalizer VT-5. The original hardware equalizer uses passive LC circuitry with class-A triode vacuum tube stages for the input and output. The input transformer is made by Jensen. The output stage utilizes the same custom Jensen transformer used on the VT-1/VT-2 mic preamps.
Most of Acustica Audio plug-ins come with a "Preamp on/off" function. With it "on" the plug-in recreates dynamically the pass-through sonic coloration of the original unit (all EQ knobs at 0 gain). This includes the harmonic distortion behavior of the hardware, the introduced phase shift and any frequency response deviations. When switched off, the plug-in offers a much "cleaner" and more linear sonic character than the hardware. Gain staging into the plug-in behaves similarly to hitting the original unit at different input levels, so Ruby comes with an "Input Trim" control. This allows for a one-knob internal gain control, by means of hidden linked input and output gain stages. When a positive value is selected, the signal entering Ruby is brought up by the set amount in dB at the device's input, and it is brought down by the same level at its output.
