DS18 CANDY-X1B 1800W Max Monoblock Amplifier

INSTRUCTIONS FOR FUNCTIONS AND CONTROLS

1. HIGH INPUT
   High level input terminals.
   Pass-Th ruoutputs:
   When input audio signal from HIGH INPUT port can start amplifier working directly instead of using
   REM cable from POWER.

2. LOWINPUT
   Left and right channels inputs of the amplifier system . Preamplifier outputs of a source ( head unit.CD player,DAT,etc. ) or of an external electronic crossover must be connected to them.

3. GAIN Knob for volume adjustment.

4. BASS BOOST The boost ranges from 0dB to 18dB.

5. BOOST FREQUENCY
   The boost frequency ranges from 40Hz to 1 00Hz.

6. LPF
   Low pass frequency adjusting knob, the frequency ranges from 50Hz to 150Hz.

7. PHASE CONTROL
   Phase adjusting switch.the phase ranges from 0-180° .

8. REMOTE CONTROLLER OUTLET
   To be connected with the remote controller, which helps to boost the gain.
   Pis turn the knob of volume to be maximum before using the remote.

9. REMOTE CONTROLLER
   Volume Level Knob, the Gain ranges from 0.2 V to +6V.

10. INDICATOR LIGHT
    When power LED sends out blue light, it means that this amplifier have being working now.
    When protection LED sends out red light, it means that the self-protection of the amplifier.

11. GND
    Ground terminal. Connect to the car chassis. Keep the length of the ground cable to a minimum.

12. REM
    Terminal to be connected with Remote cable, which comes from the source and which controls the amplifier switching on. Applied voltage must be between 10 and 1 SV DC.

13. +12V
    Anode of power connection terminals. Connect to the anode of car battery.

14. FUSE
    Standard automatic fuse, you must use the same power fuse if you need to change it.

15. SPEAKER
    Speaker connecting terminals.

TROUBLESHOOTING

Before removing your amplifier.refer to the list below and follow the suggested procedures. Always test the speakers and their wires first.

AMPLIFIER WILL NOT POWER UP.

• Check for good ground connection.
• Check that remote DC terminal has at least 1 OV DC.
• Check that there is battery power on the+ terminal.
• Check all FUSES.
• Check that Protection LED is not lit.If it is lit, shut off amplifier briefly and then repower it.

HIGH HISS OR ENGINE NOISE(ALTERNATOR WHINE) IN SPEAKERS.
Disconnect all RCA inputs to the amplifier, if hiss/noise disappears ,then plug in the component driving the amplifier and unplug its inputs . If hiss/ noise disappears, go on until the faulty/noisy component is found. It is best to set the amplifier input level as insensitive as possible.The best subjective S/N ratio is obtainable this way .Try to drive as high a signal level from the head unit as possible.

PROTECTION LED COMES ON WHEN THE AMPLIFIER IS POWERED UP.

• Check for shorts on speaker leads.
• Check that volume control on the head unit is turned down low.
• Remove speaker leads ,and reset the amplifier. If the Protection LED still comes on , then the amplifier is faulty.
• The amplifier will shut down automatically when the units· temperature goes up to as•c
• This will protect the units from damage.

AMPLIFIER’S GETS VERY HOT.
Check that the minimum speaker impedance for that model is correct.
Check for speaker shorts.
Check that there is good airflow around the amplifier.In some applications, an external cooling fan may be required.

DISTORTED SOUND.
Check that the Level control’s is set to match the signal level of the head unit.
Check that all crossover frequencies have been properly set .
Check for shorts on the speaker leads.

HIGH SQUEAL NOISE FROM SPEAKERS.
This is always caused by a poorly grounded RCA patch cord.

WARNING!

1.  Over high volume will damage your speakers.
2.  Be cautious when you use the amplifier near gasoline tank and electric wires.
3.  Protect the connecting wires and parts to avoid any damage or short circuit.
4.  The power must belee from the anode of the battery via FUSE.
5.  The sound system must be in turning-off situation when you check the amplifier.
6.  Be sure that you use the same type of FUSE when you need to replace it .
   We reserve the right to make needed change or improvement to the product, without informing customer about this in advance.
