It is a mixing console device designed to be optimized for car audio only. To this end, the mixing console apparatus for car audio according to an embodiment of the present invention includes an input unit 304, a voltage regulator 308, a control unit 310, a user control unit 312, and an output unit 314. .

The input unit 304 receives a plurality of audio signals or video signals respectively output from the plurality of external devices 302 connected to the mixing console device for car audio. For example, the input unit 304 may simultaneously receive four types of audio or video signals through four channels. The external devices 302 may be a device that outputs an audio signal, such as a radio or a CD-ROM, or may be a device that outputs a video signal, such as a DVD player.

The voltage regulator 308 receives a DC voltage applied by the vehicle battery 306 and converts the DC voltage into an output voltage which is a predetermined constant voltage. Since the car battery 306 does not continuously output constant power and outputs uneven power, the voltage regulator 308 converts the voltage applied from the car battery 306 into a constant voltage and supplies it to the controller 310. . Unlike home audio, which is usually operated by applying a high magnitude of alternating voltage, since the car audio of the present invention operates by applying a low magnitude of DC voltage, the variation of the current supplied to the controller 310 can be quite large. Therefore, by supplying a constant voltage through the voltage regulator 308, the current supplied to the control unit 310 can also be kept constant.

The controller 310 uses the output voltage output from the voltage regulator 308 as a driving voltage, and collects the audio or video signals received from the input unit 304 and outputs them through the output unit 314. Referring to FIG. 4, the controller 310 of FIG. 3 includes a four channel AV selector 402, a four band equalizer 404, a digital echo controller 406, a fade down module 408, a subwoofer output and a level control module. 410, fader controller 412, video amplifier 414, and remote output 416.

Select the signal (or the magnitude of the output signal). For example, the four-channel AV selector 402 makes it possible to selectively use four kinds of audio or video in the size of 1-DIN.

The 4-band equalizer 404 equalizes and outputs the selected audio signal when the audio signal is selected in the 4-channel AV selector 402 (for example, 4-band (BASS / MID) for allowing a user to adjust various sounds. / HI-MID / TREBLE) equalizer).

The digital echo controller 406 adjusts the sound quality by changing, repeating, and time delaying the depth of the audio signal selected when the audio signal is selected in the 4-channel AV selector 402 or the audio signal input to the microphone disposed inside the vehicle. Adjust the output. According to this, for example, the digital echo controller 406 executes the digital echo effect function so that various effects can be felt when using the microphone disposed inside the vehicle.

The fade down module 408 is provided with the audio signal or the video selected by the four-channel AV selector 402 when the driver's or passenger's voice signal is input to the front microphone when the front microphone (not shown) is disposed inside the vehicle. It controls to reduce the output level of the sound source signal of the signal and output the audio signal. This completely eliminates the inconvenience of the user separately adjusting the volume of the other sound source so that the driver does not disturb the view.

The subwoofer output and level control module 410 amplifies or adjusts the level of the base sound of the sound source signal of the audio signal or the video signal selected by the four channel AV selector 402. The subwoofer output and level control module 410 has a sub-out terminal for adjusting the volume of the added amplifier or built-in sub-out terminal for additional amplifiers to supplement the bass sound as well as its own output. To print.

The fader controller 412 adjusts the balance of the output level of the front speaker and the rear speaker when the front microphone (not shown) and the rear microphone (not shown) are arranged inside the vehicle. According to this, the user can freely adjust the balance of the front and rear speakers.

The video amplifier 414 amplifies and outputs the selected video signal when the video signal is selected by the four channel AV selector 402. For example, the video amplifier 414 may include a circuit for amplifying and outputting an input video signal by "6dB", thereby compensating for signal attenuation caused by the use of a long cable and improving video quality. Therefore, the user can improve the image quality without using another image amplifier.

The remote output unit 416 supplies an ON signal and an output voltage through the remote output terminal to another amplifier (not shown) disposed inside the vehicle. According to this, the power is supplied to a separate amplifier inside the vehicle through the remote output terminal of the present invention, the driver can conveniently operate the entire audio and video system in the vehicle without using a separate power switch. Thus, the driver can drive the entire system at once without having to switch the amplifier on and off separately.

In addition, the controller 310 may include, for example, an audio amplifier (not shown) for supplying its own output of 40 W and a level adjuster (not shown) for adjusting the volume of its own output. This allows the user to enjoy music through genuine equipment in the vehicle without having to replace or improve a separate amplifier or existing speakers. In addition, the controller 310 may further include a master fader controller (not shown) for adjusting the overall volume level and an output instruction module (not shown) for setting a circuit recording level.

3, the user controller 312 receives a voice signal input to a user input for adjusting the operation of the controller 312 or a microphone (eg, a front microphone) disposed inside the vehicle, and controls the controller ( 312).

The output unit 314 outputs a signal output from the controller 310 to the speaker 316 or the display device 318 disposed inside the vehicle.

Meanwhile, the input unit 304, the voltage regulator 308, the control unit 310, the user control unit 312, and the output unit 314 are embedded in a console case having a size of 1-DIN, which is a basic standard of a car audio box. It is preferred to be arranged.
