The  va250  50x2 @ 4ohm 10.5 volts


200w x1 bridged  11.5v

Va250

 1 - Power Supply.
Also for VA250 no compromise ever occurred; this amplifier has been designed to be capable of supplying (@12V battery) more than 500 W of regulated and clean DC power ready to be used in very short time. It works at a frequency higher  than the standard one, to make it more compact, light, insensible to  voltage variations of vehicle, making useless even for this model the presence of large and expensive battery  capacitors.
 

2 - Pre-amplifier.
VA250 makes use of the same fet circuital design of VA210; this pre-amp can do everything it has been designed for:  extreme sound transparency... as it does not exist!
 

3 - Amplifier.
VA250 can boast the same unusual circuital solution of VA210, witch use in Car environment has never been tried before; COMPLETE SEPARATION OF THE SPEAKERS FROM AMPLIFICATION CIRCUIT [Total feedback= 0].  In short, this means an extreme control of speakers drives on outputs,  with a realism, a speed and precision in the micro detail really  exciting.
 

4 -  Protection circuit.
VA250  has simple protection circuit but at the same time intended not to  interfere at all with the big and very fast current drive of the  speakers (20 Arms peak in less than 1µS). The heat-sink system  deserves a separate mention: it is studied to assure a full power  running even in conditions of poor ventilation (unfortunately very  frequent), avoiding incidental and premature shutdown.
