CEA-2006 Compliant: CEA-2006 is a system of testing and measurement methods for mobile audio amplifiers. This voluntary standard advocates a uniform method for measuring an amplifier's RMS power output and signal-to-noise ratio. The criteria for measuring power uses a DC input voltage of 14.4 volts and the RMS power output is measured into a 4Ω load, with 1% or less Total Harmonic Distortion plus noise (THD+N), and over a frequency range of 20 Hz to 20 kHz (for full range amplifiers). Signal-to-Noise ratio is measured in weighted absolute decibels (dBA) at a reference of 1 watt into 4Ω. CEA-2006 standards allow consumers to compare amplifiers on an equal basis.
Amp Overview: The Focal FPX 4.800 is a full-range Class D 4-channel amplifier. Class D amplifiers are compact, but very powerful. Its Class D design and thick aluminum chassis (3/8" on top, 11/16" on the sides) offer efficient dissipation of heat for reliable performance. The amp can be configured for four-channel, three-channel, or two-channel operation. With independent crossovers for the front and rear channels, you can configure the amplifier for low-pass, high-pass, or full-range applications.
Power Output: The amplifier has the following power output:
- 120 watts RMS x 4 at 4 ohms
- 185 watts RMS x 4 at 2 ohms
- 370 watts RMS x 2 at 4 ohms bridged
Compact Footprint: The Focal FPX 4.800 comes with 2-1/2" long mounting screws that secure the amplifier without external mounting tabs. The mounting holes are placed inside of the amp's 9-3/8" x 5-1/4" footprint and extend the entire thickness of the amp.
Protection Circuits: The amplifier is equipped with protection circuits for the following: short circuits, low impedance, power drop, thermal overload, reversed polarity, or DC offset.
Controls
Level Control (Gain): The Focal FPX 4.800 is equipped with line level inputs. The input level range is 0.2 Volts to 5.0 Volts. There are rotary input level controls for the front (1+2), and rear (3+4) channels that can be adjusted by a standard flat-head or Phillips screwdriver (not supplied).
Input Modes: There is a 2-way switch labeled "Mode" that designates the source for the inputs:
- 2CH: Inputs 1+2 are used, and the signal is mirrored to channels 3+4. This allows you to drive all four channels with one pair of inputs.
- 4CH: Inputs 1+2 and 3+4 are used. This gives you full fading capability between the front and rear.
Selectable Crossovers: The amp features high-quality crossovers that can be configured as Low pass, High pass, or Full-range. There are independent crossover controls for the front and rear channels:
- Channels 1+2: The crossover for channels 1+2 has a variable cutoff frequency from 50Hz to 500Hz, with a slope of 12dB per octave.
- Channels 3+4: The crossover for channels 3+4 has a variable cutoff frequency from 50Hz to 500Hz, with a slope of 12dB per octave. There is also a bass boost circuit on the rear channels that is variable from 0 to 12dB at 53 Hz.
Connections
Power Input: Two set-screw terminals are provided for connecting the power and ground cables. The terminals can accept up to 4-gauge wire. The set screws are tightened/loosened with the included 4mm Allen wrench.
Fuses: The amp comes with four 30-amp ATM (mini-blade) fuses; two are installed internally, and the others are replacements. The bottom panel is removed to replace the fuses. A 60-amp fuse (minimum) should be installed on the power wire within 18" of the battery.
Remote Turn-on: The remote turn-on set screw terminal will accept up to 12-gauge wire. The set screw is tightened/loosened with the included 2mm Allen wrench.
Speaker Outputs: The amplifier includes four pairs of speaker output terminals. Markings are provided for bridged connections. The set-screw terminals will accept up to 12-gauge wire and are tightened/loosened with the included 2mm Allen wrench.
Signal Input: The amplifier features two pairs of stereo RCA inputs for connecting the input signal from the source unit to the amp via RCA cables.
