Power-packed

Focal's FPX 2.750 amplifier delivers 220 watts RMS per channel in 2-channel mode, or up to 770 watts RMS when it's bridged in mono operation. This impressive power comes from a compact chassis that's a little smaller than one of my Size 10 bedroom slippers, so it'll probably fit just about anywhere in your vehicle. Focal's engineers designed this amp to reproduce your music with unerring precision, so it'll pair up nicely with a high-performance component system or a couple of subs.

Tone controls for speakers and subs

High- and low-pass filters let you optimize the signal for the best tone without distortion. When you're powering a subwoofer, the subsonic filter tames any wild rumbling, while the bass boost sets it loose when you want it. Focal includes a wired remote so you can adjust the bass level from your front seat.

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 2.750 is a full-range Class D 2-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 two-channel or mono operation. It has a built-in crossover that can be configured for low-pass, high-pass, or full-range application, and a subsonic filter. The FPX 2.750 comes with a wired remote with a 16.5' cable.

Power Output: The amplifier has the following power output:

220 watts RMS x 2 at 4 ohms
385 watts RMS x 2 at 2 ohms
770 watts RMS x 1 at 4 ohms bridged

Compact Footprint: The Focal FPX 2.750 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 2.750 is equipped with line level inputs. The input level range is 0.2 Volts to 5.0 Volts. There is a rotary gain control that can be adjusted by a standard flat-head or Phillips screwdriver (not supplied).

Selectable Crossover: The amp features a high-quality crossover that can be configured as Low pass, High pass, or Full-range. It has a variable cutoff frequency from 50Hz to 500Hz, with a slope of 12 dB per octave.

Subsonic Filter: In addition to the selectable crossover, the amp has a subsonic filter that eliminates extremely low frequencies that cause distortion and that speakers typically can't handle. The 20-50 Hz subsonic filter has a slope of 12dB per octave.

Bass Boost: The amp features a bass boost circuit that is variable from 0 to 12dB, with a center frequency of 48 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 six 30-amp ATM (mini-blade) fuses; three are installed internally, and the others are replacements. The bottom panel is removed to replace the fuses. A 90-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 two 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 a pair of stereo RCA inputs for connecting the input signal from the source unit to the amp via RCA cables.

Signal Output: In addition to the line outputs, the FPX 2.750 has a set of line outputs that can send the audio signal to a second amplifier.
