Derived from our well known VA250, from which it inherit all of its timbrical qualities, taking the place of it make possible more varied use in the car systems. 

1 - Power Supply.
Also for VA275 no compromise ever occurred; this amplifier has been designed to be capable of suppling (@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 ofvehicle, making useless even for this model the presence of large and expensive battery capacitors.

2 - Preamplifier.
VA275 makes use of the same fet circuital design of VA2150; this preamp can do everything it has been designed for: extreme sound trasparency... as it does not exist!

3 - Amplifier.
VA275 can boast the same inusual circuital solution of VA2150, wich 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 drived on outputs, with a realism, a speed and precision in the microdetail really exciting.

4 - Protection circuit.
VA275 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.
