What is AVT?
Advanced Valvestate Technology, or AVT for short, is a major step forward in hybrid amplifier design which is exclusive to our new Valvestate 2000 (VS2000) Series of amplifiers. It has evolved from the original, critically acclaimed Marshall Valvestate technology, but is improved so that it emulates even more closely the feel and response of the classic Marshall all-valve power stage...without using valves. It is not only the power stage that has been significantly improved in the VS2000 Series either. Much careful attention to detail and many hours of development have also gone into the preamp section too. As a result, each AVT channel offers the widest possible range of control and shape to your sound, with an ECC83 (a.k.a.12AX7) preamp valve adding to the all-important tone and feel of these latest Marshall creations.

Valve Drive Preamp
As just stated, each amp in the VS2000 range boasts a preamp stage equipped with an ECC83 Dual Triode valve. Drawing on our vast experience in this field, we have gone to great lengths to ensure that this precious device delivers maximum sonic benefit at all settings and volume levels. As a result, the clean sounds ring with the ‘bell-like’ harmonics that only a valve preamp can deliver and the break-up is never harsh or unnatural sounding. Whenever an AVT Overdrive channel is selected the ECC83’s dual triode is saturated to its limit, providing the dynamics and feel worthy of a place in the Marshall hall of fame.

Power Amp Delivery
The same sort of toneful care and attention was also focused on the all-important power stages of the AVT series too. Our goal was to ensure that each one would create the warm, musical feel and 3-dimensional sounds that have made our all-valve power amps world renowned. In addition, these VS2000 products were designed to deliver the goods in the often hostile and unpredictable environment of the live performance stage - which is why all the AVT power amps, from the AVT50 upwards, are fan cooled for optimum reliability.
