The series of car audio video system is meant here is the connection or installation of the system connecting the individual components of the system as a current source of electric current supply line and the connection between the components of the audio signal path system as well as video signals.
Source of electric current lines connecting cables for electric current, while the audio signal path video using video and audio cables to the speakers using speaker cables.
Car Audio Scheme
the series consists of component car audio head unit and speakers. Head of audio signal processing unit as well as an audio signal amplifier. The circuit is usually used on simple systems.
Head unit is connected to the source of electric current from the battery through the ignition, while the audio output signal directly connected with the speaker, and radio antennas directly connected to the antenna connector on the head unit, in order to catch the radio broadcast, as well as a cassette and CD player.
Car Audio with Amplifier Scheme
Car audio amplifier circuit with required when the head unit does not have its own audio amplifier or to add a sub-woofer system and is also used on a system that wants gets a loud signal.
Gain amplifier sources current from the battery, but is controlled by the head unit, so that the amplifier can be on and off right through the on / off head unit, in other words, the amplifier will be on if the head unit and amplifier on it will be off if the head unit on off not you. Thus electric current does not flow into the amplifier when the head unit is not activated.
Scheme Car Audio Video
the series of car audio video installation is essentially the audio circuit coupled with a series of video installations.
Head units, amplifiers, and a TV or Monitor get electric current from the battery, but the electric current to the amplifier and monitors controlled by the head unit, while for the electric current as a source for the TV is not controlled by the head unit, it is possible so that the TV can be turned on without depending on the head unit. When television broadcasts do not want to see the need to turn the head unit.
Splicing video path from the head unit to a monitor or TV to have to use a video cable or can also use a data cable. And also need to install the antenna to the TV in order to catch the television broadcast.
