RA220

 

This compact AUDIOPHILE-grade amplifier features low THD and IMD circuitry.
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 amplifier TRANSISTORS stage with dual differential stage, ultra-wide bandwidth, and low local feedback.
- Class AB MOSFET power stage with low local current feedback allows speaker output currents of >20A.
- Dealayed output current limiter.
- Dual regulated power supply (600W+600W) at 12V.
- Hand-assembled in our laboratory by our skilled Craftsmen.
