VALVE REACTOR TECHNOLOGY
THE POWER (AMP) AND THE GLORY!
alve Reactor technology was first used on the VOX AD60VT & AD120VT Val- Vvetronix 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 contain an actual
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
The Valve Reactor power stage is, to all intents and purposes, a bona fide valve (tube)
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.
