FDP 4.600 V2 : FOUR CHANNEL AMPLIFIER
OPERATION / CONFIGURATION MANUAL

POWER PER CHANNEL

• 4 x 150 wRMS into 4 ohms @ 1% THD
• 4 x 200 wRMS into 2 ohms @ 1% THD
• 2 x 400 wRMS Bridged into 4 ohms @ 1% THD
  DO NOT Bridge into 2 ohms
  All power ratings are at 14.4v DC.

ROUTE SWITCH

• 1+2 = All four RCA inputs are used.

• 3+4 = Input signal on channels 3+4 are routed to channels 1+2. Use this mode when you need a band pass filter on all four channels.
  Recommended when bridging channels 1, 2, 3, 4.
  The LEVEL controls still function.

• Copy = Input signal and filters on channels 3+4 are copied to channels 1+2. Use this mode when you need a band pass filter on all four channels.
  Recommended when bridging channels 1,2,3,4.
  The LEVEL controls still function.

CHANNELS 1 & 2 CROSSOVER CONFIGURATION

• Flat: Full Range Signal. No crossover filter used.
• HP: Activates the High Pass Filter for a midbass or tweeter.

CHANNELS 3 & 4 CROSSOVER CONFIGURATION

• Flat: Full Range Signal. No crossover filter used.
• HP: Activates the High Pass filter.
• LP/BP: Activates the selection of either a Low Pass filter for woofer or a Band Pass filter for midrange.
• MONO Mode: Inputs 3+4 are mixed to mono for bridge mode operation. If 1+2 ROUTE is set to COPY then 1+2 will also be mono subwoofer and the remote volume control will control level.
  The subwoofer remote volume control is activated. There is a clip distortion light on the remote volume control.
  If you see this light on, reduce volume until the light goes out so that you do not damage your speaker.

AUTOMATIC POWER TURN ON/OFF

1. The best way to automatically turn the amplifier power on and off is to use the REM wire from your source radio connected to the REM amplifier terminal.Band Pass for a subwoofer or midbass of a 3 way speaker.
2. If your original equipment stereo or source radio has a BTL amplifier then the RCA inputs have an auto turn on sensing circuit. When you connect the high level BTL speaker wires to the RCA input the REM wire is not necessary.

RCA INPUT, BOTH LOW LEVEL AND HIGH LEVEL

• The amplifier LEVEL control has sufficient adjustment range for both low level and high level input into the RCA jacks. A factory source radio that does not have RCA output, using the wires that are connected to the speakers, can be directly connected to the RCA jacks when the amplifier LEVEL control is adjusted to 8V.

SETTING LEVEL

• The best way to set system levels is to use a D’Amore Engineering DD-1 and test signals.
  Follow their gain overlap instructions.

• Set the amplifier LEVEL control to minimum before you turn on the amplifier for the first time.

• For lowest distortion and lowest noise the amplifier LEVEL should be set at the lowest setting that yields sufficient loudness without distortion. For lowest noise your source radio volume control should be near maximum that does NOT cause distortion.
  • To find the best amplifier LEVEL setting if you are NOT using a DD-1:

1. With the amplifier LEVEL at minimum, slowly increase the source radio volume until you hear distortion. Then turn it down to until the distortion stops.
2. Next, slowly turn up the amplifier LEVEL control to the maximum desired loudness, or until the red LED light flashes on the music’s ocassional peaks. (The LED turns on when there is distortion that can damage your speakers.) Listen very carefully and turn down the amplifier LEVEL control if you hear any distortion.

FDP 4.600 V2 CONFIGURATION EXAMPLES

• Set the switch to STEREO.

• Connect your tweeters to channels 1+2.
  Set 1+2 switch to HP.
  Adjust 1+2 HP frequency to the tweeter manufactures recommendation. 3500 Hz is a good starting point.

• Connect your woofers to channels 3+4.
  Set 3+4 switch to LP/BP.

• If you are NOT using a subwoofer set the 3+4 switch to LP. Adjust the 3+4 LP frequency to the manufactures recommendation. 3500 Hz is a good starting point.
  If you hear distortion in your woofers set channel 3+4 switch to BP and adjust the 3+4 HP frequency to 70 Hz.

TROUBLESHOOTING

FOCAL SIGN DOES NOT LIGHT

1. Measure the voltage at the amplifier power terminal.
   It should be between 12 and 15 volts.

2. Measure the voltage at the amplifier REM terminal.
   It should be between 12 and 15 volts.

3. If you are using BTL high level for automatic turn on, try connecting a REM wire.

4. Check your power and ground connections to be correct polarity + and – and they are tight.

5. Check battery connections.

6. Check the fuse in the REM wire.

7. Check fuse at battery.

8. Check fuse inside amplifier.
   The fuse is inside the right end cap beside the power terminals.
   The recommended ATC fuse size is two 25 amp.

FOCAL SIGN IS FLASHING

1. Is the amp very hot?
   Wait a few minutes for it to cool down.
   You need to get more fresh cool air to the amplifier.
   Do not cover the amplifier or mount it flush into a hole.

2. If the amp is cold and the Focal sign is flashing, there is an internal fault. The amplifier must then be returned for service.

NO SOUND

1. Is the Focal sign light off or flashing?
2. Is the source radio on and is there a sound signal coming from the source radio?
3. Use an ohm meter and measure the speaker wires for short circuit.
4. Check connections for small “wire whisker” that may be shorting between amplifier terminals or speaker terminals.
5. Use an ohm meter and measure the speaker for short circuit.
6. Double check your connections to the source radio.
7. Are you using the correct source radio wires and are they plugged into the correct amplifier RCA?
8. Double check your connections to the speakers and speaker crossovers.
9. Check that all amplifier switches are in the correct positions for your speaker set up.
10. Check that HP & LP frequencies are set correctly for your speakers.
11. If little or no sound, make sure that you are NOT in BP (Band Pass) Mode, with the crossover points overlapping or HP/LP frequency reversed.

AMPLIFIER BLOWS FUSE WHEN YOU TURN IT ON

1. Power and ground may be reversed.
   Check + and – polarity at amplifier and at battery.

SUBWOOFER REMOTE VOLUME CONTROL DOES NOT FUNCTION

1. Check that Remote Volume Control wire is plugged into the amplifier securely.

SUBWOOFER REMOTE VOLUME CONTROL LED LIGHT

1. While playing music the LED light should be Green.
   Occasional red LED light flash indicates that the amplifier has reached maximum loudness.

2. If the red LED light flashes with the beat of the music,
   TURN DOWN THE VOLUME before you damage your speaker.

3. If the red LED light is on continuous,
   TURN DOWN THE VOLUME before you damage your speaker.
