VN706 

STEREO MOSFET POWER AMP


Download Owner Manual    

MOSFET's transistors matched one by one.

The VN 706 is an audio power amplifier, build with discrete components, global and local negative feedback, MOSFET drivers and MOSFET power output devices.

The MOSFET's speed and wide bandwidth gives a exceptional dynamics and pure and clear sound.

Electronics, electrics and mechanicals components are highest quality, as result a product of premium quality. 

We recommend to read the section  MOSFET Technology inside this web site in order to obtain a deeply understanding about this technology. In this section you also will find advantages of feedback amplifiers and discrete components designs.

From circuital point of view the VN706 has four stages with the following characteristics:

    -input stage: voltage gain, local feedback.

    -second stage: minimize the load effect to the input stage. 

    -driver stage: voltage gain, local feedback, MOSFET driver devices.

    -output power stage: current gain, many MOSFET devices in parallel.


The VN706 has a sophisticated protection circuit, non invasive. Circuit protects: short circuits, low load impedance, DC presence, overheat.

The VN 706 has a normalized 19' x 4u cabinet according with DIN, SAE, IEC, AFNOR norms.
