Class-D Amplifier Design: The Focal FPS 1500 is a mono-channel class D amplifier offering
320W RMS into 4 ohms, or 750W RMS into 1 ohm at 0.8% THD+N.
CEA 2006 Compliant: The FPS 1500's power ratings are
measured according to the strict standards dictated by the Consumer Electronics
Association (CEA). These standards allow you to accurately compare the rated
power output of all CEA 2006-compliant amplifiers, even if they come from
different brands. Manufacturers who adhere to the standards can display the CEA
2006 logo on their products and packaging.
- CEA 2006 Rating: 320 watts x 1-channel in 4-ohms @ 20
to 2,000 Hz with 1% THD+N
1-Ohm Stable: The amplifier is stable at 4, 2, and
- 2-Ohm Rating: 550 watts x 1-channel in 2-ohms @ 1kHz
with 0.4% THD
- 1-Ohm Rating: 800 watts x 1-channel in 1-ohm @ 1kHz
Soft-Clipping: The amplifier's dynamic soft clipping feature protects
your connected speakers from distortion.
Controlled Cooling System: The Focal FPS 1500 utilizes a progressive
controlled cooling system to regulate the amplifier's temperature by controlling
air flow through an active fan and integrated cooling fins. Even before the thermo-regulated
3-1/8" low-noise cooling fan begins rotating at 122°F, the "T"
shape of the amplifier's cooling fins permits 17% of active surface heat dissipation while
guaranteeing extreme rigidity to the chassis.
Note: The cooling system only works when the amplifier temperature
exceeds 122°F. The rotation speed of the cooling system depends on the
Protection Circuitry: The Focal FPS 1500 amplifier employs
the following protection circuits- short circuit, thermal overload, over
voltage, polarity reversal.
LED Indicators: The green LED "Power" indicator means the amplifier is
on and operating properly. The red LED "Protect" indicator means that the
amplifier has shut-down and is under protection.
Anti-vibration Feet: The Focal amplifier is equipped with four
integrated damping rubber feet to resist vibration.
High-Cap Compatible (optional): The optional Focal High-Cap (091FPSCAP,
sold separately) is an external power supply module. Once connected to the Focal
amplifier, it increases the amplifier's power supply. The resulting benefit is a
higher-fidelity audio signal from the Focal amplifier and overall better music
performance, with enhanced dynamic behavior, improved speaker control and
Front-mounted Controls: The amplifier has controls
conveniently mounted on the front panel.
Gain Control: You can adjust the level of the input signal
with this rotary control. Range is 0.2 Volts to 5.0 Volts.
Low-pass Filter: Using the rotary control, you can select a
cutoff frequency between 50 Hz and 500 Hz. The low-pass filter has a slope of 12
Direct Mode: If you are using an external low-pass
crossover, you can defeat the amplifier's low-pass crossover, so that the audio signal of the Focal FPS 1500 is directly
amplified without any further crossover adjustments.
Note: In Direct Mode, the FPS 1500 has a frequency response of 10
to 2,500 Hz.
Subsonic Filter: This two-way switch lets you turn on or off
the 20 Hz subsonic filter. The subsonic filter has a slope of 24 dB/octave. The
subsonic filter helps to filter out extremely low bass frequencies that may
Bass Boost: The bass boost, centered at 45 Hz, is variable
between 0 dB and +9 dB, using this rotary control.
Phase: This features lets you set the amplifier's Phase to 0
(normal) or 180 (reverse), to better match the sound output of your system.
Wired Bass Knob: The Focal FPS 1500 comes with a wired bass-level
control knob. The bass-level is adjustable from -9 to +9 dB. The bass-level knob
also features a mute button to completely attenuate the audio coming from the
amplifier. The bass-level knob features integrated flanges and comes with two
screws to mount the unit under the dash. It includes a 16' cable to connect to
Note: The wired remote measures 2.625" (w) x 1.0625 (h) x 2.4375"
Front-mounted Terminals: The Focal FPS 1500 has all of the cable connections on the front of the
amplifier for a clean installation.
Power Input: Two set-screw terminals are provided for
connecting the power and ground cables. The terminals can accept up to 2-gauge
wire, however, a 4-gauge wiring kit is sufficient for the 60-amp rating of the
built-in fuse. The set screws can be tightened/loosened with the supplied Hex
Remote Turn-on: A set screw terminal for connecting the remote turn-on lead. The terminal will
accept up to 10-gauge wire. The set screw can be tightened/loosened with the
supplied Hex wrench.
Speaker Outputs: 2 pairs of set-screw terminals are provided
for an easy parallel subwoofer connection. The terminals
can accept up to 8-gauge wire. The set screws can be tightened/loosened with the
supplied Hex wrench.
Pseudo-Balanced Inputs: The amplifier is equipped with one
pair of left & right gold-plated RCA jacks
for the input signal from the head unit. These pseudo-balanced inputs help to
reject ground noise.
Remote Control: An RJ-14 jack for connecting the supplied
remote bass control module.
ATO Fuses: The amp is equipped with two 40-amp
ATO fuses. Two spare fuses are included with the amplifier.
