30 secondes apres je lisais ca sur le site de Diezel :
Citation : The VH4s is in fact a VH4 in STEREO! All features of the VH4 are present TWICE in the VH4s! This additional option enables the use of wide stereo effects for two cabinets or to use one cabinet "dry" and the other one "wet". Because of the stereo set-up the power output gets down to 50 Watts per side, therefore the sounds are even a little bit softer than the VH4, but the maximum volume is about the same.
