When size matters

If you want an audio upgrade but you're short on room, Focal's FD 2.350 may be the amp for you. This 2-channel amplifier packs a respectable punch, driving two speakers with up to 170 watts RMS each even though it's only the size of a small paperback book. You can also bridge the amp to mono mode to power a sub with 360 watts RMS.

Without cover

No sacrifices

The amplifier's active high- and low-pass crossovers and bass boost let you get hands-on with with sound optimization. And if you're keeping your factory radio, the amp comes with external audio transformers that automatically detect and convert the high-level signals from your speaker wires.

Cool under pressure

The FD 2.350 uses Direct FET Technology to dissipate heat efficiently from its aluminum chassis, ensuring long-term reliability. And speaking of saving space, you can stack this amp with its FD Series 4-channel brother to power an entire system.

Product Highlights:

  • ultra-compact D class 2-channel amplifier

My system has plenty of power. Who needs an amp?

You might think you don't need an amp because you have a 400-watt system in your car, or because your new stereo puts out 50 watts a channel. But those are peak wattage ratings, which may boil down to 15 or 20 watts per channel, using the more realistic RMS rating. An amp sends your speakers the power they need to deliver your music with clarity and impact, whether you're using factory speakers or high-performance components. And low-frequency reproduction requires lots of power, so an amp is an absolute must if you're adding a sub to your system.

Features

CEA-2006 Compliant: CEA-2006 is a system of testing and measurement for mobile audio amplifiers. This voluntary standard advocates a uniform method for measuring an amplifier's RMS power output. 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). CEA-2006 standards allow consumers to compare car amplifiers and receivers under the same conditions (apples to apples). Using CEA-2006 criteria, the Focal FD 2.350 is rated at 105 watts RMS x 2 channels.

2Ω Stable: The amplifier can also support a 2Ω load; the 2Ω power output is 170 watts RMS x 2 channels.

Bridgeable: The FD 2.350 is bridgeable to one channel at 360 watts RMS into 4Ω.

Stackable: All the FD series amps (FD 1.350, FD 2.350, and FD 4.350) have the same footprint, and can be stacked on top of one another.

Speaker Level Input: An external speaker level input transformer is included, used when your source unit doesn't have RCA outputs. The transformer is connected to the amp with the included wiring harness. The transformer's dimensions are approximately:

  • Width: 2-3/8"
  • Height: 1-1/4"
  • Depth: 2" (3" including wiring)

Auto Turn-on: When using a speaker level input, the amp will turn on automatically when it senses the input signal.

Controls

Gain: To accommodate the varying range of signal levels from today's factory and aftermarket radios, the FD 2.350 features an adjustable gain control; 0.2-5.0 volts line level (RCA) and 0.4-10.0 volts speaker level.

Crossover: Set the crossover switch to LPF (Low Pass Filter), Full (full range), or HPF (High Pass Filter).

Frequency: The crossover point is continuously variable from 40 Hz to 400 Hz.

Bass Boost: The bass boost, centered at 85 Hz, is variable from 0 dB (flat) to +12 dB.

Connections

Power Connections: The power, ground, and turn-on connections are 0.3" wide screw terminals. A Phillips-head or flat blade screw driver (not supplied) is required to tighten/loosen the terminals. Crimp-on spade connectors are included for all three terminals.

Speaker Outputs: There are 0.3" wide screw terminal outputs for two speakers. A Phillips-head or flat blade screw driver (not supplied) is required to tighten/loosen the terminals. Crimp-on spade connectors are included for both speakers.

Line Level Input: The line input is a pair of stereo RCA jacks.

Speaker Level Input: An external speaker level input transformer and wiring harnesses are included for the speaker level input.

Fuses: The amplifier uses two 15-amp mini blade-type fuses.
