RB NN Determined by the Pre Amp selection VALVE REACTOR TECHNOLOGY THE POWER AMP AND THE GLORY alve Reactor technology was first used on the VOX AD60VT amp AD120VT Val V vetronix amps Since conventional modeling effects for line recording are not used directly with a speaker they do not include a power amp circuit output transformer or speaker In other words they only have a preamp circuit A real valve amp sound however is produced not just by the preamp but also by the tone and distortion of the power amp and by the constant changes in impedance that are cre ated by the power amp driving the speakers The AD15VT AD30VT AD50VT AD100VT amp AD100VTH contain an actual low wattage valve power amp circuit a virtual output trans former patent applied for that uses solid state components to simulate an output trans former and a dummy speaker circuit that simulates the varying impedance of a real speaker This means that although it s low power the power amps used in both the AD15VT AD30VT AD50VT AD100VT amp AD100VTH have the same circuit structure of an actual all valve tube amp While much of the tone creation and shaping carried out is done in the digital domain the Valve Reactor power amp is 100 analogue The resulting journey your gui tar s signal takes through the analogue world of the power stage plays a major role in pro viding the all important feel and tone of the original amps we modelled

18. The Valve Reactor power stage is to all intents and purposes a bona fide valve tube push pull power amplifier but in miniature It utilizes a 12AX7 ECC83 valve a dual tri ode device meaning two valves in one and is equipped with an output transformer just like a real valve amp The power amp output signal is designed to read the constantly changing impedance curve of the dummy speaker circuit system and feed this information back to the virtual output transformer just like an all valve amplifier does This information permits the behavior of the valve stage to vary with the speaker load impedance which is another important part of real world valve tone Apart from the vital valve tone this ingenious power amp design provides it also allows us to replicate various circuit characteristics that are unique to the all valve power stages of the amps we ve modelled These characteristics include Class A or Class AB operation Presence and Resonance low end control circuitry both found in the negative feedback circuit that some but not all valve power amps have and power output Being able to match such vital characteristics helps ensure that each and every one of our models is as tonally authentic as possible as opposed to the usual close but no cigar norm of digital modeling And just so you know this patented in USA power amp technology is unique to VOX Valvetronix Quick Start ual a chance it s been
