The MTX Audio RFL4001D mono block amplifier is a powerhouse of clean power. It is at the cutting edge of technology and performance.
With more than 4000W RMS in class-D (very high efficiency), it pushes the limits of amplification. To achieve this, we spent three years in development to bring together the best in high-fidelity and in high-output. We also used the best components available.
The power supply is cut by the most efficient MOSFETs available from the best manufacturer, International Rectifier (USA). They support 640A each, 175°C and there are 12 of them. We used 6 transformers to distribute the load and the temperature.
The energy storage at the power supply output is provided by 23 Elna capacitors, with low resistance and ultra fast. They withstand 105°C, but never exceed 60°C even after 5 days at full output! On the power stage, we used MOSFETs from International Rectifier which support 280A each.
To verify the correct operating balance of the RFL4001D, we monitored it with a $35,000 thermal racing camera. This allowed us to monitor the temperature of each component and the width / thickness of each track on the PCB. It's been a painstaking job, but the MTX RFL4001D performs much better than our wildest dreams. The RFL4001D is the highest performing amp ever built by MTX.
