Furthermore, sound operators are required to simultaneously play the content and adjust the volume twice linearly. This manual operation suffers from low efficiency, susceptibility to errors, operator absences leading to poor meeting quality, and lengthy training periods for replacement personnel.

[0035] Specifically, the power control circuit 110 includes a socket J1, a fuse F1, a switch S1, a power on / off self-locking relay K1, a diode D1, a power transistor Q1, a resistor R4, a diode D2, an upper power module, capacitors C81, C82, C6, and C5, a lower power module, and a second step-down voltage regulator circuit. The socket J1 is connected to the mains power. The fuse F1 is connected to the socket J1. The switch S1 and the power on / off self-locking relay K1 are connected in parallel to the upper power module and the lower power module. The gate of the power transistor Q1 is connected to the resistor R4. The source of the power transistor Q1 is grounded. The drain of the power transistor Q1 is connected to the anode of the power on / off self-locking relay K1 and the diode D2. The capacitors C81 and C82 are connected in parallel to the upper power module. The capacitors C6 and C5 are connected in parallel to the lower power module and the second step-down voltage regulator circuit. The upper power module and the lower power module are AC to DC power modules.

Pins 1, 5, and 6 of socket P1 are grounded. Pin 2 of socket P1 is connected to resistor R5, and pin 3 of socket P1 is connected to resistor R2. Capacitors C1 and C2 are connected in parallel to pin 4 of socket P1 and the cathode of diode D3. Capacitors C3, C4, and C80 are connected in parallel to the anode of diode D3 and the connection point of the first and second buck regulator circuits. Capacitors C7, C8, and C9 are connected in parallel to the second buck regulator circuit. The first buck regulator circuit is denoted as VR1, and the second buck regulator circuit is denoted as VR2.

[0036] When the automatic venue audio preset player is in the off state, the USB signal of the computer USB input circuit 170 is input through socket P1. The USB power supply is provided by pin 4 of P1 to the 5V output of the computer USB input circuit 170. After anti-interference filtering by C1 and C2, it is connected to the file system processing decoding chip 120. Diode D3 blocks the 5V power supply output of USB to power other units or modules, preventing the system from sending incorrect USB signals. That is, pins 2 and 3 of P1 output USB signals.

[0037] like Figure 3 As shown, after compatibility matching with resistors R2 and R5, the circuit is connected to pins 6 and 5 of the file system processing decoding chip U1, enabling chip U1 to enter the working state. Capacitors C18 and C19 are power supply input / output anti-interference filter capacitors, respectively. Capacitors C17 and R16 form the peripheral circuit of chip U1. Chip U1 internally contains an arithmetic logic unit (ALU), a controller, and RAM. When chip U1 detects the computer's USB signal, the file system processing decoding chip 120 first outputs 3.3V from pin 11 to power the FLASH memory U2 (e.g., ...). Figure 4 (As shown), and initialize the FLASH memory U2 to enter the working state, then Figure 3 Pins 6 and 5 of the file system processing decoding chip U1 send USB response data packets to the target computer, which are identified as file editing modes such as data VID and PID. The computer then recognizes the current device as a USB flash drive to facilitate editing of preset content. Figure 3 R19 is the signal compatibility resistor for FLASH memory U2, and C21 is the power supply anti-interference filter capacitor for FLASH memory U2.

[0038] It should be noted that AC 220V (mains power) is output from pins 1 and 2 of socket J1, and then connected to the S1 power button (switch) and the power on / off self-locking relay K1 after passing through fuse F1. The power control circuit operates as follows: When the S1 power button is pressed, AC 220V supplies power to both the upper and lower power modules. The upper power module outputs DC 12V for drive power, with C81 and C82 serving as anti-interference filter capacitors for the drive power supply. The lower power module outputs DC 12V, which, through the step-down regulator circuits VR2, C6, C5, C80, C3, and C4, provides a stable 5V power supply to the system. Simultaneously, through the step-down regulator circuits VR1, C7, C8, and C9, it provides a stable 3.3V power supply to the system, enabling the system to enter the working state. The power-on control level (MCU_POWE) is output from pin 26 of the program logic chip CPU1 and sent back to the power control circuit 110. After being clamped and protected by diode D1, the signal passes through the compatible protection resistor R4 and then enables the switching transistor (power transistor) Q1. Switch Q1 then turns on, allowing the DC power supply to be connected. When the 12V power-on self-locking relay K1 coil is energized, the system is no longer affected by the S1 power-on button; pins 15 and 14 of chip U1 communicate with pins 29 (MCU_DAT) and 44 (FAT32_DAT) of the programmable logic chip CPU1 via compatible matching resistors R10 and R11 (e.g., Figure 5 The system is recognized as being in player mode and boots up successfully. At this point, it can respond to presets with one click, and the volume is automatically controlled according to the curve. The automatic volume control is achieved by the CPU1 program logic chip communicating with the U1 file system decoding chip. The power-off is achieved by the human-machine interface of the touch screen through the program flow, responding to the CPU1 pin 26 outputting the power-off control level (MCU_POWE) in the same way as above, and finally de-energizing the power-on self-locking relay K1 coil of the power control circuit 110 to complete the power-off.

[0039] See Figure 5The programmable logic chip 130 (CPU1) internally contains an arithmetic logic unit (ALU), a control unit, and RAM. Capacitors C10 and C12 (first filter circuit) provide power and anti-interference filtering for the chip's digital circuits. Inductor L1 and capacitor C11 provide power and anti-interference filtering for the chip's analog circuits. An active oscillator (first oscillation circuit) composed of crystal oscillator U7 and resistors R27 and R28 provides the operating clock for CPU1. Resistors R25 and R26 and capacitor C24 provide the analog sampling reference point voltage for CPU1. Resistors R22 and R24 select the operating mode of the RAM in CPU1. Capacitor C22, adjustable resistor R21, resistor R20, capacitor C23, diodes D4 and D5, chip IC2, and socket P6 provide automatic reset functionality for CPU1 in case of an error. Resistors R17 and R18 select the operating mode of the ROM in CPU1. IC1 provides the program memory function for CPU1, and C13 provides power and anti-interference filtering for IC1.

[0040] See Figure 6 An active oscillator (second oscillation circuit) composed of crystal oscillator U8, resistors R39 and R42 provides the operating clock for the logic circuit inside the IC5 chip. C25 (second filter single channel) provides power to the IC5 chip and is an anti-interference filter capacitor. Resistor R35 provides the reset voltage for the IC5 chip. The peripheral circuit consists of resistors R51, R50, R48, R47, R45, R44, R43, R41, R40, R38 and capacitors C30 and C29 connected to the analog unit inside the IC5 chip, providing the Internet analog voltage conversion conditions. Pins 26 and 24 of the IC5 chip output the Internet network status signal. After passing through current-limiting resistors R34 and R37, the network status is indicated by LEDs D6 and D7. Resistors R29, R30, R31, R33, R36 and capacitors C26, C27, and C28 perform shaping and filtering on the Internet network signal waveform to make the Internet line more reliable. Ultimately, the IC5 chip processes digital network communication requests and responses from the CPU1 via pins 32, 33, 34, 35, and 36, and sends program data packets from the Internet to the CPU1. Pin 36 of the IC5 chip provides a response request start signal to the CPU1. Resistor R32 is an anti-interference resistor for the IC5 chip's request start signal to prevent communication errors. The purpose is to enable the CPU1 to automatically and remotely control the lighting via the Internet while responding to preset music with a single button press, thus achieving the function of synchronized lighting when responding to preset music with a single button press.

[0041] See Figure 7The touch coordinate control signal of CPU1 is communicated via SPI through pins 1 to 5 of P4. The control signal of the display screen is output from CPU1 to pins 29 to 32 of P4. The data bus of the display screen is output from CPU1 to pins 33 to 56 of P4. The display screen is supplied with various voltage power supplies by pins 12, 14, 16, 19, 21, 23, 24, 26, and 28 of P4. C14, C15, and C16 are the power supply filter capacitors for each channel.

[0042] It should be understood that by configuring a FLASH memory 100, a power control circuit 110, a file system processing decoding chip 120, a programmable logic chip 130, an audio input mixing and adjustment output circuit 140, a wireless remote control circuit 150, and a network driver circuit 160, the power control circuit 110 receives mains power to supply power to the programmable logic chip 130. The programmable logic chip 130 receives the wireless remote control signal from the wireless remote control circuit 150 and controls the file system processing decoding chip 120 to identify the audio data in the FLASH memory 100 according to the wireless remote control signal. The audio data is then mixed and output through the audio input mixing and adjustment output circuit 140. The programmable logic chip 130 also adjusts the volume according to the corresponding audio data through the network driver circuit 160.

[0043] Outputting lighting adjustment signals to the lighting control console can solve problems such as difficulties in coordinating with sound operators for meetings and performances, low manual efficiency, easy errors, high energy consumption, or slow response of sound and lighting. It can automatically respond to preset audio data and control the volume to the venue standard. The lighting control console can be remotely controlled via the network to achieve preset lighting synchronization. The wireless remote control can achieve automatic response and multi-person cooperation. It is easy to operate and uses a mixing method to overlay channels without affecting the use of the original media equipment.

[0044] Optionally, the audio preset player further includes a keyboard circuit connected to the program logic chip, the keyboard circuit being used to perform time flow control on the program logic chip.

[0045] In this embodiment, a keyboard is not required when a touch screen is available. (See attached document.) Figure 8S2, S3, S4, S5, S6, S9, S10, and S11 are individual buttons, which, in conjunction with the S7 time flow switch, can automatically respond to presets with a single touch. LEDs D8 to D13 indicate the current position of the S7 time flow switch, LEDs D14 to D16 indicate the device's operating status, and resistors R66 to R74 provide current-limiting power to the indicator lights.

Resistors R57, R58, R62, R63, R64, and R65 provide accurate level signals to the S7 time flow switch. Ultimately, the programmable logic chip CPU1 processes the button and display functions.

[0046] See Figure 9 and Figure 10 C10 is the wireless power supply anti-interference capacitor. Resistors R12, R13, R14, and R15 provide accurate level signals for the wireless remote control signal from socket P5. The wireless remote control function is processed by the programmable logic chip CPU1. This function allows the sound system operator to respond to the actions of the host or performers without requiring high-intensity attention; the host or performers can respond with a single button press using the remote control. When using the wireless remote control, the keyboard and touchscreen are automatically locked and automatically unlocked after the remote control operation ends to prevent simultaneous triggering and potential errors.

[0047] See Figure 10 External audio from other media is input from port P3 (audio input port), coupled by resistors R1 and R7 in conjunction with an isolation transformer, limited by the dual potentiometers R6 and R9 (mixer adjustment module), and output from port P2 (audio output port), without affecting the original equipment. The local audio is mixed by resistors R3 and R8 and then limited by the coupling transformer for output.
