CONTROLS
KS-AX5104
KS-AX5102
1 Input LEVEL controller
The input level can be adjusted with this control when this unit is connected to other source
Subwoofer
equipment. Adjust the level while listening to the sound. This control is preset to MIN when
the unit is shipped.
2 BASS BOOST controller
Turning this boosts the 45 Hz frequency within the range of 0 dB to +18 dB. Adjust the level
Subwoofer
while listening to the sound. This controller is preset to MIN when the unit is shipped.
3 CROSSOVER frequency controller
Turning this adjusts the cutoff frequency within the range of 50 Hz to 200 Hz. Adjust the level while
listening to the sound. This control is preset to 50 Hz when the unit is shipped.
4 CROSSOVER filter switch
OFF: N ormally set to this position. The switch is preset to this position when the unit is shipped.
LPF: S et to this position when you want to turn on the LPF (Low-Pass Filter) switch.
HPF: S et to this position when you want to turn on the HPF (High-Pass Filter) switch.
5 POWER lamp
The green lamp lights while the unit is turned on.
PROTECT lamp
If the lamp lights in red with the unit on, some trouble has occurred (see "TROUBLE SHOOTING").

TROUBLESHOOTING

For more details, consult your JVC car audio dealer.
The POWER lamp does not light.
• Change the fuses if the current one is blown.
• Connect the ground lead securely to a metal part of the car.
• Turn on the equipment connected to this unit.
Subwoofer
• Use a relay if your system employs too many amplifiers.
• Confirm the battery voltage (11 V to 16 V).
The PROTECT lamp lights in red and/or the unit heats up abnormally.
• Use the speakers of suitable impedance.
• Correct the speaker wirings if they are short-circuited.
• Make the speaker wirings away from the power cord to prevent DC offset error.
• Leave the unit turned off for a while to cool it down.
No sound is heard.
• Confirm the connections for the power supply (see "POWER SUPPLY" on page 1).
• Connect RCA pin cords to the INPUT jacks, or the speaker input connector to the HIGH INPUT terminal.
Rear
Speaker
Alternator noise is heard.
• Keep the power cords away from the RCA pin cords.
• Keep the RCA pin cords away from other electrical cables in the car.
• Connect the ground lead securely to a metal part of the car.
• Make sure the negative speaker leads do not touch the car chassis.
• Replace the plugs or use plugs with load resistors.
• Connect a bypass capacitor across the accessory switches (horn, fan, etc.).
• Connect the LINE NOISE FILTER (commercially available) between Line Output (through the receiver)
and INPUT jacks on this unit.
Noise is made when you connect the unit to an AM tuner.
Subwoofer
• Move the speaker and power cords away from the antenna lead.
