Compact 4 channel Premium Amplifier - 4 x 70 W

Overview

A musical and compact amplifier by Focal



Designed to offer great flexibility of use, the Focal FPX 4. 400 is a very compact four-channel amplifier of 4 x 70 Watts under 4 ohms (CEA power). Its operation in 4/3/2 channel mode and its stability under 2 ohms make it a powerful and versatile model capable of meeting all your expectations. Its high power allows you to drive the front and rear speakers, or a Hi-Fi installation with a 2-way front kit and a subwoofer.


Focal know-how


The FPX amplifiers are built on thick aluminium chassis (9.5 mm on the top, 17.5 mm on the sides) and advocate efficiency as much as heat dissipation. The distribution of components on the motherboard has been carefully designed to optimise the cooling capacity of the chassis.

Careful selection of Class D components - a switch-mode power supply, oversized toroidal transformers and high quality capacitors - has resulted in powerful, musical and truly compact amplifiers. Easily integrated, this Focal amplifier also delivers a very important power to meet the expectations of enthusiasts!


Power and musicality


The FPX 4.400 delivers 4 x 100 Watts RMS under 2 ohms. In bridged mode, it delivers 2 x 200 Watts RMS under 4 ohms, which allows a good bass channel to be animated with the 3 and 4 ohms channels. It is also stable under 2 ohms to adapt to different types of speakers.

To perfectly manage the speakers, each pair of channels has a configurable crossover from 40 to 5000Hz: high pass, low pass.

    Super happy

    The parcel arrived quickly, in good condition.
    The product also works very well, so I'm very happy and I'd buy from LDLC again without hesitation.

    Average sound quality

    I have received my package and quite quickly it has been a few days. I was looking for a car amp with a very good sound quality, but I am still a bit disappointed.
