acv DX-4.80 Car 4 Channel Power Amplifier

By our policy of continuous monitoring and improvement of specifications and design, this manual is subject to change without prior notice to the user

INTRODUCTION

Congratulations on your purchase of an ACV car amplifier! The amplifier has been engineered, designed, and manufactured so you can enjoy quality sound for a long time. For installation of this amplifier, we recommend contacting professional installers of car audio. Please read the user’s manual carefully and throughout before the installation and the first operation of the amplifier. It is recommended to keep this manual in a safe place for further reference.

INSTALLATION PRECAUTIOUS

when replacing a fuse, use only the same rating as recommended by the manufacturer. Using a fuse with a higher or lower rating can damage the amplifier or may result in fire or electric shock.
do not touch the amplifier body with wet hands, and also do not touch the amplifier when the amplifier body is wet;
it is not recommended to listen to music at very high volume levels while driving. Otherwise, you will not be able to hear the signals of other drivers;
periodically check the condition of the power wires and fuses, and if necessary, they can be replaced;
during installation, to avoid short circuits or electric shock, make sure that the negative terminal is not connected to the battery or the car body;
carefully choose the place of attachment for the amplifier, and make sure that while drilling you do not break the power wires, gas tank, and other structural parts of the car;
do not let various liquids come into contact with the amplifier case, this may lead to a short circuit, and the amplifier and speakers may also burn out.
before installation of the amplifier, first, remove the negative terminal from the battery so as not to cause a short circuit;
carefully insulate all power connections of wires with high-quality professional electrical insulation tape;
do not use electrical insulating tape in places where high temperatures are possible, as it can easily melt.

TO AVOID DESTRUCTION OR DAMAGE:

do not connect several negative speaker wires to the same negative terminal of the amplifier;
this line of amplifiers is designed for a voltage of 12V, so check the onboard voltage before installation;
when leaving the car, it is recommended to always switch off the head unit, otherwise the battery will be completely discharged.

TERMINAL WIRED CONNECTION

it is not recommended to connect bare wires to the power terminals, as this may cause fire or short circuit;
it is necessary to periodically check the wire connections to ensure they are securely connected;
do not twist tangled wires together;
lay the wires in special insulating tubes;
when laying the wires, make sure that they do not touch moving parts of the car, such as the gearshift lever, handbrake, seat adjustment lever, etc;
do not shorten any wires, otherwise, the protective system will not work as expected when it is necessary;
never supply power to another source by extending a wire from an already connected device.
The nominal resistance may not be enough and the wire overheats, as a result of which a fire may OCcur;
when replacing a fuse, use only the same rating as recommended by the manufacturer. Using a fuse with a higher or lower rating can damage the amplifier or may result in fire or electric shock;
do not connect a loudspeaker with a lower impedance rating than recommended by the manufacturer of the amplifier. This can damage both the amplifier and the subwoofer;
when installing the audio cables between the RCA outputs of the head unit and the RCA inputs of the amplifier, the audio and power supply cables should, if possible, not be routed along the same side of the vehicle. It is recommended a separate installation, e.g, routing the power cable through the cable channel on the left side and the audio cables through the cable channel of the vehicle on the right side or vice versa. This prevents interferences due to crosstalk into the audio signal.

FILTER BANDPASS

ACV DX-series is equipped with the bandpass filter (BP) function that allows, if adjusted rightly, to pass only the required frequencies to your loudspeaker. To do this, select the channels (CH1/CH2 or CH3/CH4) to which the speakers are connected, turn on the buttons located next to the HPF, and LPF filters, and use the controls to adjust the frequency band for connected speakers, cutting off the extra frequencies of the sound range from above and below. If you turn off the buttons next to HPF and LPF filters, the frequency band will be full which is 10Hz ~ 30kHz. Enabling only one button opposite HPF or LPF will allow the user to adjust only the high-frequency range or only the low-frequency range of channels CHl/CH2 or CH3/CH4.

CONNECTION DIAGRAM

Car amplifier turn-on control wire. Connect this terminal to the corresponding wire on the head unit. The terminal can also be connected to a car antenna resistor. Another way is to connect the turn-on control wire to the car ignition.
