Input LEVEL controller
The input level can be adjusted with this control when this unit is connected to other source
equipment. Adjust the level while listening to the sound. This control is preset to MIN when
the unit is shipped.
LPF (Low-Pass Filter) controller
Adjust the cutoff frequency (the Low-Pass Filter transmits frequencies lower than the cutoff
frequency) within the range of 50 Hz to 300 Hz. Adjust the level while listening to the sound.
This control is preset to 50 Hz when the unit is shipped.
PHASE switch
Select either normal (NOM) or reverse (REV), which reproduce a better sound. This switch is
preset to NOM when the unit is shipped.
BASS BOOST controller
Turning this boosts the 45 Hz frequency within the range of 0 dB to +18 dB. Adjust the level
while listening to the sound. This control is preset to MIN when the unit is shipped.
SUBSONIC fi lter controller
Adjust the cutoff frequency (the subsonic fi lter rejects frequencies lower than the cutoff
frequency) within the range of 20 Hz to 50 Hz. This control is preset to 20 Hz when the unit is
shipped.
POWER/PROTECTOR lamp
The lamp lights in green while the unit is turned on. When the lamp does not light or lights in
red with the unit on, it indicates there may be any trouble (see "TROUBLESHOOTING").
Power lndicator
The blue lamp illuminates while the unit is turned on.

TROUBLESHOOTING
For more details, consult your “JVC IN-CAR ENTERTAINMENT” car audio dealer.
The POWER/PROTECTOR 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.
• Use a relay if your system employs too many amplifi ers.
• Confi rm the battery voltage (11 V to 16 V).
The POWER/PROTECTOR 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.
• Leave the unit turned off for a while to cool it down.
No sound is heard.
• Confi rm the connections for 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.
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.).
Noise is made when you connect the unit to an AM (MW/LW) tuner.
• Move the speaker and power cords away from the antenna (aerial) lead.
