The power output of the FPX 4.800 amplifier ensures that you will get the best out of your high-end speaker drivers.


  • 4-/3-/2-channel Class D amplifier
  • 2-/4-channel input modes
  • Stable at 2 Ohms
  • Active crossover for each pair of channels
  • The FPX 4.800 measures 921⁄64 x 513⁄64 x 23⁄32″ (23.7 x 13.2 x 5.3 cm).


For an amplifier to provide high power and musicality, efficiency and heat dissipation are two essential aspects.

In order to optimise these two key aspects, FPX amplifiers have been given a thick aluminium chassis (3/8″ / 9.5 mm for the top, 11/16″ / 17.5 mm for the sides).

The distribution of the components on the motherboard was also carefully researched to optimise the cooling capacity of the chassis.

The careful selection of each Class D component (switching power supply, oversized toroidal transformers and high-quality capacitors) has made it possible to create powerful but compact amps with excellent musicality


  • A powerful and ultra-compact amplifier
  • Perfect for audiophile installations or powerful subwoofer systems
  • Optimised heat dissipation
  • Extremely versatile
  • Remarkable power/performance/price ratio
