FOCAL FPX5.1200 5-channel D-Class Amplifier
With the FPX 5.1200, installation of this hi-fi system is much easier as there’s only one amplifier and one power supply to fit into the vehicle. In order to control this 5-channel installation (with front and rear speaker drivers, and a subwoofer), the FPX 5.1200 features a wide range of settings. The input selector (2/4/6 channels) duplicates channels, meaning there will always be 5 output channels, even if the head unit only has one or two stereo outputs. For the main speaker drivers, each pair of channels has an adjustable active crossover. To perfectly tune the subwoofer to the rest of the installation, the bass channel has a low-pass active crossover, a bass equaliser, phase adjustment and a subsonic filter (particularly useful for cutting off frequencies which are too low for a small subwoofer). The remote control enables you to adjust the bass level from the driving seat depending on the type of music you’re listening to. Stable at 4 and 2 Ohms, this new FPX amplifier will drive most speaker drivers on the market with just the right amount of power: 4 x 75 Watts + 1 x 420 Watts RMS at 4 Ohms (CEA standard). With the launch of the FPX 5.1200, Focal now offers a full range of amplifiers, from the Impulse ‘Plug & Play’ amplifier, to the audiophile FPX amplifier. Through our compact FD amplifiers, Focal is able meet the expectations of all those looking for a car audio amplifier. With its high power, great musicality and compact design, as well as being ideal for powering a complete installation with Flax or K2 Power speaker drivers, the FPX 5.1200 will meet all the expectations of hi-fi car audio enthusiasts.
Extensive research for unprecedented power in a compact enclosure
Delivering very high power from such a compact enclosure is a true challenge. The more heat an amplifier produces, the higher the risk of distortion affecting the system’s musicality. By using Class D technology, Focal has reduced the need for heat dissipation for its FPX range. However, in order to achieve high efficiency and to optimise reliability, FPX amplifiers required extensive research: selection of the best components, a thick aluminum chassis, very precise positioning of the components, monitoring heat dissipation with a thermal camera and accelerated aging tests in draconian conditions. Focal’s goal is to offer electronics equipment which is very compact and powerful, but without sacrificing musicality. The dimensions of the 5-channel FPX 5.1200 amplifier (337 x 175 x 57mm / 13.25"x 6.8" x 2.25") are nearly the same as the FPX 4.400 SQ. The FPX 5.1200 has a maximum power of 4 x 120 Watts + 1 x 720 Watts at 2 Ohms!
