The AC power input unit 130, the program input unit 140, An AMP output unit 160 connected to the amplifier, and four multi-channel analog input signal units 170.

The DSP controller module 100 is an integrated circuit that converts an applied analog signal into a digital signal, performs predetermined processing, and outputs a signal converted into an analog signal again.

FIG. 14 is a block diagram schematically showing the configuration of a DSP controller module capable of a touch screen according to an embodiment of the present invention.

Referring to FIG. 14, there are shown a signal converter 10, a signal converter 10, an analog-to-digital converter (ADC) 10 including an AD converter 30 for converting an applied analog signal into a digital signal and a DA converter 40 for converting an output signal into an analog signal. A channel selector 20 for selecting a signal to be controlled among the multi-channel input signals digitized by the AD converter 30 of the AD converter 30 or a channel of an analog signal output from the DA converter 40 of the signal converter 10 A volume control unit 11 for controlling the level of a channel selected by the channel selection unit 20, a control unit including a main MCU 50 and a DSP MCU 60 for controlling the overall settings of the multi- A user interface unit 90 for generating an input signal according to a touch or an operation of the touch screen, and a screen display unit 200 for visualizing and displaying a set value and a control result value to be controlled.

The control unit includes a main MCU 50 and a DSP MCU 60 for performing overall control of the multi-channel amplifier control apparatus 100. The control unit includes an application program and a process unit for driving each configuration, For example, a CPU (Central Processing Unit) or an MPU (Micro Processor Unit).

Specifically, the main MCU 50 controls the input signals and the DSP MCU 60 controls the output signal of the main MCU 50. That is, the main MCU 50 receives the settings and the like input through the screen display unit 200 through the user interface 90, outputs the settings through the channel selection unit 20 and the signal conversion unit 10, 60 change and adjust the respective setting values to the settings inputted by the user through the screen display device 200. [

The signal converting unit 10 includes an AD converter 30 for converting an analog signal applied to the DSP controller module 100 into a digital signal and a DA converter 40 for converting the control signal into an analog signal. For example, when the DSP controller module 100 is related to a power amplifier, a signal input to the signal converter 10 is a signal applied from a pre-amplifier. A preamplifier is a device that receives a signal from a source device, selects the source to listen to, adjusts the volume, and outputs the signal to the input level of the power amplifier.

The channel selector 20 can select signals to be controlled among the four multi-channel input signals digitized by the signal converter 10. [ Here, in a multi-channel amplifier or a multi-channel amplifier system, a channel means the number of terminals (speakers) that can be connected to the amplifier. More specifically, it refers to a method in which an audio frequency band is divided into a plurality of bands, and an exclusive speaker is sounded for each band using an amplifier for each band. It divides the output of the preamplifier into necessary bands with a divider (multi-amplifier divider) and amplifies them with a dedicated power amplifier to drive the speaker. This approach has the advantage of reducing distortion of the intermodulation.

The ball noise control unit includes a pink noise generator 70, so that it is possible to test whether the set value is suitable for the environment by checking the output sound of the speaker without a separate input signal in a listening environment in which the equipment is installed.

In particular, the user interface unit 90 may include a simplified icon ICON, It is preferable to be able to easily change the set value and simultaneously output the set value in real time. In addition, the user interface unit 90 may include input devices such as a microphone, a physical sensor, a keyboard, a mouse, a joystick, and the like as well as any type of input means that can be developed in the future.

It is recommended for the user's convenience that the user interface unit 90 and the screen display unit 200 are integrated in a form of a touch panel which can be changed by touching a screen having a desired set value.

The specific operation of the DSP controller module will be described in more detail below.

5 is a photograph showing a front screen display unit of a user interface unit of the DSP controller module 100 according to an embodiment of the present invention. FIGS. 6 to 13 are views showing a DSP controller module 100 according to an embodiment of the present invention. And the respective screens of the front screen display unit of the display unit 100. [

Referring to these drawings, the screen display unit 200 of the DSP controller module 100 visualizes and displays menus and control result values to be controlled by the DSP controller module 100. Also, the screen display unit 200 can display a specific menu and user data input by the user.

According to the present invention, the screen display unit 200 of the DSP controller module 100 displays eight menus, and the user can easily adjust the control bar displayed on the screen display unit 200 to a desired size have.

In addition, the user can easily adjust the screen of the screen display unit 200 by touching and dragging, and also can fine-tune the fine adjustment button unit 121 by selecting the menu (mode).

First, the volume adjustment mode 201 adjusts the levels of the four channels selected by the channel selection unit 20. Each channel can be adjusted to the desired size.

The compressor mode 202 reduces the dynamic range of the audio signal by reducing signal amplification of the channel selected by the channel selection unit 20 or compressing a loud sound. Likewise, the user can adjust with a simple touch or drag method using a hand or a pen.

Here, there is no effect on the signal of the set maximum level (threshold level) or less, but when the input signal level exceeds this level, the amplification factor is reduced to prevent the output from becoming large. The rate at which the signal above the threshold level is suppressed is generally indicated by the Ratio. The output level when this is maximized is set so that it never exceeds the threshold level.

The equalizer mode 203 may be configured to divide the frequency of the signal selected by the channel selector 20 into 31 frequencies and adjust the volume of each frequency to output a sound corresponding to the speaker characteristics.

The crossover mode 204 is a kind of filter that separates the electric signal selected from the channel selection unit 20 in the frequency domain. The crossover mode 204 divides the sound signal of the amplifier into a high / low band or a high band / Each frequency range and sound pressure can be adjusted by the user in a touch or drag manner and distributed to each unit.

The delay mode 205 generates a delay time of four channels, and an arbitrary time value is set so that an output sound is generated after the delay value has elapsed as compared with the source sound.

According to the present invention, as shown in FIG. 11, the delay mode 205 may be configured to generate an output sound by setting an arbitrary time value or setting a distance m on the screen. The distance m is set to 15 preset values, and the user can easily select the 15 preset values or adjust the fine adjustment button 121 when more detailed adjustment is required.

Therefore, by simply touching and setting the distance m of the delay mode 205, a better sound effect can be realized according to the use environment.

The limiter mode 206 is a device and a circuit for controlling the maximum level of the selected channel signal among the four channels in the channel selection unit 20 to a predetermined level or less, Thereby preventing the speaker from being damaged by the distorted signal.

Preset mode 207 includes a preset PI and a user setting UI and allows the user to change the default value of the sound control device set at the factory through the preset PI The settings of the menus can be variously changed and stored through the user setting (UI), and can be easily selected and used according to various environments.

Lastly, the setting mode 208 can modify or change the setting of the entire menu, which allows the user to set and change the menus more smoothly.
