The JDV-Pre utilises a class-A amplifier for optimal signal transfer. But unlike all other amplifier designs, the JDV-Pre's front end is completely void of the negative feedback loops normally used to stabilize the circuit. This revolutionary design eliminates the use of phase-cancellation which inevitably degrades the signal. This is augmented with Drag Control™ load correction that allows the engineer to optimise the load on the instrument pickup for the most natural rendering. A fully variable high-pass filter provides additional advantages for acoustic instruments by gently rolling off the low end to eliminate troublesome body resonance while allowing each instrument to sit more comfortably in the mix.
