Focal FPX4.400SQ - Performance Series 4 x 100W 4 Channel Amplifier

The FPX 4.400 is a very compact 4-channel amplifier with a power of 4x70 Watts RMS at 4 Ohms. Offering a 4-/3-/2-channel mode, stable at 2 Ohms and equipped with an active crossover for each pair of channels, the FPX 4.400 is the most “sound quality” model in this range. Thanks to its very comfortable power, this is the ideal amplifier for powering front and rear speaker drivers, or for hi-fi installations with a 2-way kit in the front and a subwoofer. The 2-/4-channel input modes ensure compatibility with head units only equipped with a pair output lines. The power and musicality of this amplifier will ensure you get the best out of your high-end speaker drivers from our Performance line. 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.
