[0027] Specifically, the mode selection buttons include a hall mode button 21, a small hall mode button 22, and a conference mode button 23. Pressing a mode selection button calls the mode parameters preset in the processor with one click, allowing users to switch between different scene modes with one click, eliminating the need for pre-debugging steps and making use faster and more convenient.
[0028] In this embodiment, the audio parameters of the hall mode, small hall mode and conference mode are first preset in the processor. When the mode selection button is pressed to select one of the modes, the processor changes the input sound field effect according to the selected mode and outputs it through the output module to achieve the desired mode effect.
[0029] Specifically, the audio source input selection buttons include a first AUX input selection button 31, a second AUX input selection button 32, a Bluetooth input selection button 33, and a coaxial input selection button 34.

By plugging a microphone into the microphone input interface, one can speak directly through the microphone. The sound information is processed by the processor and amplified and output by the output module. While the microphone is plugged in, external devices can be connected through other input interfaces to play music files. For example, a mobile phone can be connected to the AUX input interface via a data cable. Then, by pressing the corresponding AUX input selection button, an audio file can be input through the mobile phone. After being processed by the processor, it is sent to the output module for amplification and output. Thus, one can speak into the microphone while background music is playing.
[0030] Specifically, the output interfaces include a main audio output interface 51, a center output interface 52, a subwoofer output interface 53, and a speaker output interface 54. The main audio output interface 51 can be connected to a cascade amplifier; the center output interface 52 can be connected to a center speaker amplifier or an active center speaker; the subwoofer output interface 53 can be connected to a subwoofer amplifier or an active subwoofer; and the speaker output interface 54 can be connected to a 4-16Ω professional speaker.

There are multiple output level indicators 83, each illuminating in accordance with the output level, accurately displaying the amplifier output signal level.
[0033] Specifically, a cooling fan 9 is bolted to the wiring panel 102 and connected to the main control circuit board via wires. Multiple cooling holes 91 are formed on the side of the chassis 1. The cooling fan 9 and the cooling holes 91 work together to increase air flow within the chassis 1, speeding up internal heat dissipation and preventing high temperatures from affecting the device's service life.
[0034] Furthermore, the power interface 62 is detachably connected to a fuse. The power interface 62 in this embodiment is a fuse power interface 62 in the prior art, which effectively protects the internal part of the device from burning due to excessive current, and the fuse is detachable and replaceable.
[0035] Furthermore, mounting holes 1011 are respectively provided at both ends of the operation panel 101. The chassis 1 can be screwed and fixed to a designated position for use through the mounting holes 1011.
