VA2250

 
 





 

This reference amplifier features an ultra-wideband (400kHz) circuitry with low THD and IMD.
Our proprietary zero total feedback audio circuitry delivers a sound unlike any other car audio brand.
The result of years of work, it recreates the soundstage with all the realism and speed present in the original recording.
- Class A FETs input preamplifier.
- Class A amplifier stage with dual current mirror differential with FETs and TRANSISTORS, ultra-wide bandwidth, and low local feedback.
- Class AB MOSFET power stage with low local current feedback allows speaker output currents of >40A in less than 1 uS.
- No output current limiter.
- Regulated 1400W 12V power supply.
- Hand-assembled in our laboratory by our skilled Craftsmen.
