Under the Hood
To achieve the extreme power-to-size ratio in the FP+ Series, LAB GRUPPEN engineers refined and upgraded two proprietary technologies: the regulated switch-mode power supply (R.SMPS™) and the patented Class TD™ output stage. Both are incorporated in all four FP+ Series amplifiers. Working together, this new generation of proprietary circuits produces more power from a smaller package while at the same time maintaining LAB GRUPPEN’s peerless reputation for sonic excellence.
To ensure efficient, uniform cooling, the ultra-efficient Intercooler® uses thousands of tiny copper cooling fins to increase exposure of the heat sink to the cooling air flow.
Twin variable-speed fans respond to temperature sensors, forcing air over the Intercooler fins in a front-to-rear flow. All output devices are mounted transverse to the airflow, so the cooling effect is uniform. There are no “end-of-tunnel” output transistors subject to greater warming and, consequently, possible premature failure.
