Focal FDS 4.350

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 and signal-to-noise ratio. The criteria for measuring amplifier power uses a DC input voltage of 14.4 volts and the RMS power output is measured over a frequency range of 20 Hz to 20 kHz (for full range amplifiers), with 1% or less Total Harmonic Distortion plus noise (THD+N). Signal-to-Noise ratio is measured in weighted absolute decibels (dBA) at a reference of 1 watt into 4 ohms. CEA-2006 standards allow consumers to compare car amplifiers and receivers under the same conditions (apples to apples).

CEA-2006 Specifications:

• Power Output: 58 watts RMS x 4 into 4Ω
• Signal to Noise Ratio: 84 dBA (measured at 1 watt into 4Ω)

Other Specifications:

• Power Output:
  • 2Ω: 100 watts RMS x 4
  • Bridged: 200 watts RMS x 2 (4Ω minimum)
• THD: 0.05%
• Frequency Response: 10 Hz to 50 kHz

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

Controls: The two amplifier sections (CH 1-2 and CH 3-4) have independent gain and crossover controls.

• Gain: rotary gain controls; continuously variable 0.2 to 5.0 volts
• Crossover: three position switches; LPF (Low Pass Filter), Full (full range), or HPF (High Pass Filter)
• Frequency: rotary controls; the low pass/high pass crossover points are continuously variable from 40 Hz to 400 Hz
• Input Select: three position switch; choose 3/4 (when using four dedicated RCA inputs), 1/2 (when using two RCA inputs to feed all four channels stereo signals), or 1+2 (when powering stereo speakers with channels 1/2 and bridging channels 3/4)

Connections:

• Power: The power and ground 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 both terminals.
• Remote Turn-on: The remote turn-on is a 0.22" wide screw terminal. A Phillips-head or flat blade screw driver (not supplied) is required to tighten/loosen the terminal and a crimp-on spade connector is included.
• Speaker Outputs: There are 0.22" wide screw terminal outputs for four 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 the speakers.
• Line Level Input: There are two pair of line level stereo RCA input jacks. The amplifier does not accept speaker level inputs.
