APPARATUS FOR CONTROLLING OUTPUT SIGNAL OF CAR AUDIO SYSTEM

摘要

PURPOSE: An apparatus for controlling an output signal of a car audio system is provided to output audio signal sound through only a speaker of a car audio system if one-touch monitoring button is turned on. CONSTITUTION: An apparatus for controlling an output signal of a car audio system includes a logic circuit(30). The logic circuit removes pop noises generated in case of a power on/off and audio signal of a car audio system. In order to remove them, the logic circuit performs a logic operation about a mute signal and one-touch monitoring signal. and outputs a control signal for turning on the first speaker(11) of the speaker(10). The mute signal turns off an output signal of the speaker. The one-touch monitoring signal is generated when the on-touch monitoring button is turned on. By the control signal of the logic circuit, audio signal generated from the first amplifier(21) of the amplifier(20) is applied to the first speaker. Thereby, a first speaker mounted to a front left side(FL) with reference to the driver's seat generates a predetermined audio signal.
