CONTROLS
To operate the following controls, detach the control cover. Attach it again after operation.
Control cover
Status lamp
The lamp normally lights in blue while the unit is turned on.
•When the lamp does not light
•When the lamp lights in red
•When the lamp lights in violet frequently
–It indicates there may be a problem. See “TROUBLESHOOTING” on the right column.
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
Adjust the cutoff frequency (the
PHASE switch
Select either normal (NOM) or reverse (REV), whichever reproduces 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 filter 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.

The BASS BOOST controller boosts the 45 Hz frequency within the range of 0 dB to 18 dB. Adjust the level while listening to the sound.
TROUBLESHOOTING
For more details, consult your JVC car audio dealer.
The Status lamp does not light.
•Change the fuses if the current one is blown.
•Confi rm the connections for the power supply (see “POWER SUPPLY” on page 1).
•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 so many amplifiers.
•Confi rm the battery voltage (11 V to 16 V).
The Status lamp lights in red and/or the unit heats up abnormally.
•Use speakers of a suitable impedance.
•Correct the speaker wirings if they are
•Leave the unit turned off for a while to cool it down.
The Status lamp lights in violet frequently. (Clipping*)
•Lower the input level with the Input LEVEL controller until the lamp lights in violet a few times. * It means that the amplifier circuits are overloaded and the sound may distort due to too much
input from the car receiver.
No sound is heard.
•Confi rm the connections for the power supply (see “POWER SUPPLY” on page 1).
•Connect the RCA pin cords to the INPUT jacks.
•Confi rm the speaker wirings (See “SPEAKER CONNECTIONS” on page 2).
Alternator noise is heard.
•Keep the leads of the POWER terminals 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 tuner.
• Move all the leads of this unit away from the antenna lead.
