用更容易理解的方式，分享系统选型、现场调音与日常维护中的关键知识。
Practical guidance on system selection, live mixing and everyday maintenance.
稳定的现场不只依赖设备，也依赖正确的增益结构、合理的扬声器布局和清晰的操作流程。
Reliable live sound depends not only on equipment, but on gain structure, loudspeaker placement and clear operating workflows.
扬声器位置、覆盖角度、混响与频段平衡都会影响听众能否听清。盲目增加音量，反而可能让声音更混浊。
Placement, coverage, reverberation and tonal balance determine whether speech is understood. More level can sometimes make the result less clear.
从话筒输入到主输出保持合理电平，可以减少底噪、避免削波，也让均衡、压缩和效果器更容易控制。
Healthy levels from microphone input to main output reduce noise and clipping while making EQ, compression and effects easier to manage.
定期检查线材、接口、无线频率、电池、散热与预设文件，可以在聚会前发现隐患，减少现场中断。
Checking cables, connectors, wireless frequencies, batteries, cooling and show files before use helps prevent interruptions.
