LEGENDS
LO PASS (low pass): the LO PASS potentiometer means that you can set the low pass filter frequency.
The value selected is the frequency below which the signal will be amplified.
NOTE: the LO PASS potentiometer on the FP 4.75 model amplifier relates to channels 1, 2, 3 and 4.
The LO PASS switch located at the top of the control panel relates to channels 1 and 2; whereas the one at
the bottom corresponds to channels 3 and 4.
NOTE: the LO PASS feature on the FP 5.500 model amplifier may ONLY be activated using the SUB ouput.
This filter should only be used if the amplifier is connected to a subwoofer, but UNDER NO CIRCUMSTANCES
WHATSOVER IF IT IS CONNECTED TO A FULL RANGE KIT. In that case it will enable you to set the
frequency up to which the subwoofer will re-transcribe the audio signal.
Example : X-OVER in LPF position, LO PASS set at 80Hz: the subwoofer connected to the amplifier will re-
transcribe the signal amplified, up to 80Hz.
Status indicator: Status indicator: the indicator lets you know whether or not the amplifier is working
properly. If the LED (light-emitting diode) indicator is green, your amplifier is switched on and operating
normally. If the LED display light is red, your amplifier is being protected following some kind of malfunction
– i.e. overheating, defective cabling, etc.
FUSE: the FUSE connector is where the amplifier fuse(s) are positioned. When replacing fuses, ensure that
the new fuse has exactly the same rating as the old one.
NOTE: the FP 5.500 amplifier has internal fuses. If your fuses need to be replace, please bring your
amplifier back to your Focal dealer.
+BATT: the +BATT power connector is used for the power supply cable which connects the amplifier to the
battery's positive (+) terminal.
REM: the REM connector links the amplifier with the source (car radio) via a REM or REMOTE car radio
output. This enables the automatic turn-on of the amplifier when powering on the source (car radio).
GND: the GND (ground) power connector receives the negative (-) cable ensuring the link between the
amplifier and the vehicle's chassis.
SPEAKERS: the SPEAKERS' connectors link the amplifier and the loudspeakers' crossovers (or the
loudspeakers in case of integral crossovers). It is IMPERATIVE to respect the polarities (+ amplifier ‡ +
crossover or + speaker / - amplifier ‡ - crossover or - speaker).
NOTE: the SPEAKER output of the FP 1.800 amplifier is ONLY for the connection of one or several
subwoofer(s).
NOTE: the SPEAKERS outputs of the FP 5.500 amplifier are ONLY for connecting coaxial, 2-way or 3-way kits.
DO NOT CONNECT A SUBWOOFER to these outputs.
