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 FDP 6.900 is a full-range Class D
6-channel amplifier. Class D amplifiers are compact, but very powerful. Its Class D
design and compact aluminum chassis offer efficient dissipation of heat for
reliable performance. The amp can be used to drive six full-range or component
speakers, driving two pairs of full-range or component speakers and one
subwoofer with bridged channels, bridged for three subwoofers, or tri-amplify a
subwoofer, woofer, and tweeter. With multiple crossovers built-in, you can configure the amplifier
for low-pass, high-pass, or band-pass applications.
Power Output: The amplifier has the following power output:
- 150 watts RMS x 6 at 4 ohms
- 200 watts RMS x 4 + 275 watts RMS x 2 at 2 ohms
- 400 watts RMS x 2 + 500 watts RMS x 1 at 4 ohms bridged
- 600 watts RMS x 1 at 2 ohms bridged (Channels 5+6 only)
Speaker Level Inputs: The RCA inputs will accept either
speaker-level or line level signals from your car's head unit. A speaker level
signal is connected to the RCA inputs using a speaker wire to RCA adapter (sold
Selectable Balanced/Unbalanced Inputs: The amp features two
internal DIP switches that allow you to change the standard "unbalanced" inputs
to "balanced floating ground" inputs to minimize noise. The amplifier's end
panel must be removed to change the switch positions.
Auto Turn-on: When using a speaker level input, the amp will
turn on automatically when it senses the input signal.
Invisible Mounting Brackets: The Focal FDP 6.900 includes a mounting
bracket that is not visible outside of the amp's footprint. The 13-7/8" x 2-3/4"
bracket fits into the bottom panel, and has tabs that fit inside of the
amplifier. The bracket is attached to the mounting surface with the supplied
self-tapping screws, while the amp is mounted to the bracket with the supplied
countersink screws. A pair of external mounting brackets are also included.
Front-mounted Controls/Terminals: The amplifier controls and
terminals are all mounted on the front panel for a clean installation and easy
Protection Circuits: The amplifier is equipped with
protection circuits for the following: short circuits, thermal overload,
reversed polarity, or DC offset.
Level Control (Gain): The Focal FDP 6.900 will accept both line level and speaker level inputs. The input level range is 0.2 Volts to
8.0 Volts. There are rotary input level controls for the front (1+2), rear
(3+4), and subwoofer (5+6) channels that can be adjusted by a standard
flat-head screwdriver (not supplied).
Input Selection: There is a 3-way switch labeled "Inputs"
that designates the source for the inputs:
- 2: Inputs 1+2 are used, and the signal is routed to
channels 3+4 and 5+6.
- 4: Inputs 1+2 and 3+4 are used. The signals from 1+2
and 3+4 are attenuated by -6dB and routed to channels 5+6. This allows you
to have constant bass loudness on 5+6, while you fade between channels 1+2
- 6: All 6 inputs are used.
Linkwitz-Riley Crossovers: The amp features high-quality
12dB per octave Linkwitz-Riley crossovers that can be configured as low pass,
band pass, high pass, or flat (full-range). There are independent crossover
controls for the front, rear, and subwoofer channels:
- Channels 1+2: Channels 1+2 can be set to Flat
(full-range signal/no crossover used) or high pass only. The cutoff
frequency is variable from 50Hz to 4000Hz. You can also choose to copy the
signals from channels 3+4 to channels 1+2. This is helpful when a band pass
filter is needed for those four channels and when bridging channels 1, 2, 3,
- Channels 3+4: Channels 3+4 can be set to Flat
(full-range), high pass, and a choice of low pass/band pass (separate
- Channels 5+6: Channels 5+6 can be set to Flat, high
pass, low pass/band pass (separate switch), or Sub Mode. In Sub Mode, inputs
5+6 are mixed mono for bridged mono operation. The crossover slope becomes
24dB per octave and the subwoofer remote volume control is activated. There
is also a high pass subsonic filter that eliminates very low frequencies
that the subwoofer cannot play cleanly, and may cause damage.
Remote Volume Control: The FDP 6.900 includes a wired remote
volume control. The
remote has integrated flanges and screws are included to mount the unit under the
dash. It includes a 16.5' cable to connect to the amplifier. The wired remote measures
approximately 1-5/8" wide (2-5/8" including
the mounting flanges) x 3/4" tall x 1-1/2"
deep (2-1/8" including the knob and cable).
Power Input: Two set-screw terminals are provided for connecting
the power and ground cables. The terminals can accept up to 4-gauge wire, which
is recommended for the 75-amp rating of the built-in fuses. The set screws
are tightened/loosened with the included 4mm Allen wrench.
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.
Note: The remote turn-on is not needed when a
speaker-level input is used. The Auto Turn-on circuit will automatically
turn on the amp when a signal is detected (or turn off the amp when the
input signal is no longer detected).
Speaker Outputs: The includes six 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 three pairs of stereo RCA
inputs. If no line level signal is available, you will need speaker wire to RCA adapters (sold separately) to connect the amplifier to the
source unit via speaker wires.
Remote Control: The RJ-25 jack is for connecting the supplied
Fuses: The amp has three internal 25-amp ATO fuses. The end
panel must be removed to access the fuses.
