Focal FPX 4.800 amplifier

Focal FPX 4.800 amplifier

POWERFUL AND VERSATILE. The FPX 4.800 is a very compact 4-channel amplifier with an output of 4x120 W RMS at 4 Ohms. Offering 4-/3-/2-channel mode, stable at 2 Ohms and equipped with an active crossover for each pair of channels, the FPX 4.800 is the most versatile model in the FPX range. Thanks to its very high output, it is the ideal amplifier for powering front and rear speaker drivers or for hi-fi installations with a 2-way set in the front and a subwoofer. 2-/4-channel input modes ensure compatibility with head units equipped with only a pair of output lines. The high performance and musicality of this amplifier will give you the best of your high-end Performance loudspeaker drivers.

Number of amplifier channelsAmplifiers are divided into: - Monoblocks - 2-channel - 3-channel - 4-channel - 5-channel - 6-channel - multi-channel Each channel is used to power one speaker for the coaxial type, or one side if they are component speakers. Monoblock type amplifiers are mainly used for subwoofers. 2-channel are suitable for both subwoofers and, for example, the front pair of speakers in a car. 3-channel is used for front or rear speakers + subwoofer. 4-channel are used for front + rear speakers or 1 pair of speakers + subwoofer. 6 or 5-channel are used for 2 pairs of speakers + subwoofer, most often. Bridging means connecting the amplifier to a bridge, using the + pole from one channel and the - pole from the other channel. In most cases this is shown as "BRIDGED" on the amplifier.	4
Energy class of the amplifierAmplifiers are divided into two basic classes: analog and digital . Analog amplifiers (A/B) have higher consumption requirements, but usually have a more natural sound. Digital amplifiers (D) have significantly lower consumption and higher efficiency, but the sound may not be as faithful as with classic analog amplifiers.	D
RMS power into 4 ΩRMS power when loading speakers or subwoofer at 4 Ω. RMS power is the constant power of the amplifier and is one of the most important parameters when choosing an amplifier.	4 x 120 / 2 x 370 W
RMS power into 2 ΩRMS power when loading speakers or subwoofer at 2 Ω. RMS power is the constant power of the amplifier and is one of the most important parameters when choosing an amplifier.	4 x 185W
Low-pass filter (LPF)LPF / LP or "low pass filter" offers the possibility to adjust the amplifier using a potentiometer so that the lower band plays only the frequencies in a certain band that you need. This filter is used to adjust the frequency range for the subwoofer, so that it does not overload or distort the sound. Example: Amplifiers most often have an LPF from 20 to 300 Hz. We recommend setting this potentiometer in the range of 45-80 Hz.	50 - 500 Hz
High pass filter (HPF)HPF / HP or The "hi pass filter" offers the option of setting the amplifier using a potentiometer so that medium, possibly mid-bass and treble frequencies play upwards from a certain frequency. Example: Amplifiers most often have an HPF from 40 to 300 Hz. If we set the potentiometer to a value of approx. 150 Hz, the sound will be clipped so that it plays frequencies from 150 Hz up to the maximum upper limit of the entire frequency range of the amplifier, perhaps up to 20,000 Hz. We recommend setting this potentiometer in the range of 80-160 Hz. Thanks to this setting option, the speakers can handle a higher performance, as you will not overload them with bass in the lower frequency range.	50 - 500 Hz
High level inputsThe high-level input on the amplifier allows connection directly to the existing speakers in the car without additional purchase of an external high/low adapter. Important equipment in the case of installing an amplifier on an original car radio.	Yes
Automatic on and offThis function allows you to automatically switch on the amplifier.	Yes
Socket input terminalsFerrule terminals allow better wiring contact to the amplifier. It is also a more secure form of terminals. If you are tightening the sleeve terminals, we recommend retightening them after 1 day, as the connected cable gradually compresses.	Yes
Input for wired remote controlIf the amplifier has a remote control input.	Yes
