had assembled in italy the VA 210
" polypropylene capacitors on signal path and input wiring with
The va250 50x2 @ 4ohm 10.5 volts
200w x1 bridged 11.5v
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.
