RA475x

 
 


This compact, AUDIOPHILE-grade amplifier features a low THD and IMD circuitry.
Our proprietary zero-reaction 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 stage with dual transistor differential, ultra-wide bandwidth, and low local feedback.
- Class AB MOSFET power stage with low local feedback allows for speaker output currents of >10A.
- Bult as Dual Stereo
- Forced ventilation with double regulated fans
- Delayed output current limiters
- 2x 450W at 12V stabilized power supplies
- Hand-assembled in our workshop by our skilled craftsmen.
