How to Use 120V Appliances in The U...

How to Use 120V Appliances in The UK? An Electrical Engineer Answers!

A.POWER STA, US LED
This bi-color LED glows green when power is on and no problems are present. If one of the protection circuits comes on, it will change to red.
B.PHASE SHIFT
Use this switch to help compensate for time alignment problems in the system. Such problems usually result from having the subwoofer at a different distance from the listener than the other speakers in the system.
C.Flash lighting
This switch controls the use of RGB lights. Press the switch and it will remain in constant light mode when no music signal is connected. Input music signal, the color of the LED light, and the light flashing mode will change with the music. When the switch is turned off, the LED light stops working.
Warning: This product has an RGB light flickering effect, please do not stare directly at the light for a long time, so as to avoid eye discomfort
D.LOW PASS FILTER This control permits you to define the frequency range you want the subwoofer amplifier to receive. The subwoofer will reproduce all sounds BELOW the frequency you set.
Note: The low pass filter frequency can be higher or lower than the standard. There has +1-20% tolerance.
E.BASS BOOST
The BASS BOOST feature will increase the sound level in the bass frequencies.

F.INPUT GAIN CONTROL
After you have installed your system, turn this control to a minimum.
Turn the head unit on (and the subwoofer will turn on via the remote connection). Turn the head unit volume to about 213 full level.
Slowly turn up the subwoofer input and gain control until you hear a small amount of distortion. Then reduce the level until the distortion is completely gone. Level the control at this setting.
G.REMOTE LEVEL CONTROL PORT
Attach the included remote level control to control the volume level of the subwoofer independently.
H.HIGH LEVEL (speaker level) INPUTS
If your head unit does not have RCA outputs you can use the speaker outputs for the audio source for the subwoofer. Use the supplied cable and wire harness and connect the outputs properly as shown in the connection diagram in this manual.
I.LOW LEVEL RCA INPUTS
Low-level inputs are the recommended way to introduce the audio signal to the subwoofer if RCA outputs are present on your head unit or another signal source (such as a sound processor).
J.FUSE
Do not use a fuse with a different value and NEVER replace the fuse with a wire or coin.
K.POWER INPUT TERMINAL

Low-Level Input Wiring
Low-level (RCA) input wiring is preferred for the best audio performance. Most trunk or hatchback installations will require a 15-20 feet RCA cable, while pickup trucks and under-seat installations will require a 6-12 feet RCA cable. Always use a high-quality cable.

NOTE: Do not connect BOTH the high-level and low-level inputs from your receiver to your amplifier at the same time!

High-Level Input Wiring
The high-level input(s) should only be used when your receiver lacks RCA outputs. If the RCA outputs are not present. connect the speaker outputs from the receiver to the high-level input connector of the amplifier. Be sure to observe polarity to avoid audio phase problems.
NOTE: Do not connect BOTH the high-level and low-level inputs from your receiver to your amplifier at the same time!

Power Connections
Connect the ground terminal to the closest point on the chassis of the vehicle. Keep this ground wire to less than 39″ (100 cm) in length. Use 8 gauge (or heavier) wire.
Connect the remote terminal to the remote output of head unit using 16 gauge ( or heavier ) wire.
Connect an empty fuse holder within 18″ (45 cm) of the car battery, and run 8 gauge (or heavier) cable from this fuse to the amplifier location. Then connect the fuse holder to the “BATT+” (+12V) connection on the subwoofer rear panel.

NOTE: In this connection, the AUTO TRUN OFF Switch is in the On position

NOTE: In this connection, the AUTO TRUN ON Switch is in the On position

Remote Level Control Connection

Install The remote control securely under the dash or in a similar location where using it will not distract the driver.

Troubleshooting

If you experience operation or performance problems with this product, compare your installation with the electrical wiring diagram on the previous pages. If problems persist, read the following troubleshooting tips which may help eliminate the problems.

The amplifier will not power up.
Check to make sure you have a good ground connection.
Check that the Remote Input (Turn-On) has at least 5VDC. Check that there is battery power on the (+) terminal.
Check that there is at least 12v.
Check all fuse, and replace if necessary.
Make sure that the Protection LED is not illuminated. If it is lit. shut off the amplifier briefly, and then repower it.
Protection LED comes on when the amplifier is powered up| Check for short circuits on speaker leads.
Turn down the volume control on the head unit to prevent overdriving. Remote speaker leads, and reset the amplifier. If the Protection LED still comes on, then the amplifier is faulty and needs servicing.
No output.| Check that all fuses are OK.
Check that unit is properly grounded.
Check that the Remote Input (Turn-On) has at least 5VDC.
Check that the RCA audio cables are plugged into the proper inputs. Check all speaker wiring.
Low output.| Reset the Level Control.
Check the Crossover Control settings.
High hiss in the sound.| Disconnect all RCA inputs to the power sub’s control panel. If the hiss disappears, then plug in the component driving the amplifier and unplug its inputs. If the hiss disappears at this point. go on until the faulty/noisy component is found.
It is best to set the amplifier’s input level control as low as possible. The best subjective signal-to-noise ratio is achieved in this manner. Try to set the head unit as high as possible (without distortion) and the amp input level as low as possible.
The squealing noise is present.| Check for improperly grounded RCA interconnects.
Distorted sound.| Check that the Input Level Control is set to match the signal level of the head unit. Always try to set the Input Level as low as possible.
Check that all crossover frequencies are properly set.
Check for short circuits on the speaker leads.
Amplifier gets very hot.| Check that the minimum speaker impedance for the amp model is correct Check that there is good air circulation around the amp. In some applications, it may be necessary to add an external cooling far,.
Engine noise (static type)| This is usually caused by poor-quality RCA cables, which can pick up radiated noise. Use only the best quality cables, and route them away from power cables
Engine noise (alternator whine)| Check that the RCA grounds are not shorted to the vehicle chassis Check that the head unit is properly grounded.
