報告廳音響是指用于在大型報告廳、會議室或演講場所中提供音頻播放和擴聲功能的音響系統。它的設計和配置應考慮到場地的大小、聲學特性以及用戶的需求。以下是報告廳音響系統的一般介紹：
Lecture hall audio refers to a sound system used to provide audio playback and sound reinforcement functions in large lecture halls, conference rooms, or speech venues. Its design and configuration should take into account the size of the site, acoustic characteristics, and user needs. The following is a general introduction to the sound system in the lecture hall:
主音箱（主揚聲器）：報告廳音響系統通常會包括一對主音箱，安裝在舞臺或前方位置，用于主要的聲音放大和擴散。主音箱應具備高保真度、高聲壓級和均衡的音質，以確保清晰、逼真的聲音傳遞。
Main speaker (main speaker): The sound system in the lecture hall usually includes a pair of main speakers installed on stage or in the front position for main sound amplification and diffusion. The main speaker shall have high fidelity, high sound pressure level and balanced sound quality to ensure clear and realistic sound transmission.
副音箱（輔助揚聲器）：為了實現整個報告廳的音響均衡覆蓋，可以設置多個副音箱，分布在報告廳的不同區域。副音箱可以根據場地的聲學特性和覆蓋范圍的需求進行合理布置。
Sub speakers (auxiliary speakers): In order to achieve balanced coverage of the entire lecture hall, multiple sub speakers can be set up and distributed in different areas of the lecture hall. The auxiliary speakers can be arranged reasonably according to the acoustic characteristics and coverage requirements of the venue.
混音器：混音器是報告廳音響系統的核心部件，用于調節各個音源的音量、音色和平衡，以獲得良好的音頻效果。混音器還可以接受多個音源輸入，如麥克風、音頻播放設備等，并將它們混合成一個統一的音頻信號輸出。
Mixer: Mixer is the core component of the auditorium audio system, used to adjust the volume, color, and balance of various sound sources to achieve good audio effects. The mixer can also accept multiple audio source inputs, such as microphones, audio playback devices, etc., and mix them into a unified audio signal output.
無線麥克風系統：為了滿足演講者的需求，報告廳音響系統通常會配備無線麥克風系統。無線麥克風系統可以提供便捷的使用和移動性，使演講者可以自由地在報告廳內活動，并通過麥克風傳輸清晰的聲音信號。
Wireless microphone system: In order to meet the needs of speakers, the lecture hall audio system is usually equipped with a wireless microphone system. The wireless microphone system can provide convenient use and mobility, allowing speakers to freely move around the lecture hall and transmit clear sound signals through the microphone.
播放設備：報告廳音響系統可以連接各種音頻播放設備，如CD/DVD播放器、MP3播放器、計算機等。這些設備可以提供音頻內容的播放和背景音樂的提供。
Playback equipment: The lecture hall audio system can connect various audio playback devices, such as CD/DVD players, MP3 players, computers, etc. These devices can provide playback of audio content and background music.
效果器：報告廳音響系統中的效果器可以增強音頻的效果，如混響、均衡、壓縮等。通過合理的效果器調節，可以改善音頻的空間感和質感，提升聽眾的聽覺體驗。
Effector: The effector in the sound system of the lecture hall can enhance the audio effect, such as reverberation, equalization, compression, etc. By adjusting the effector appropriately, the spatial and texture of the audio can be improved, enhancing the audience's auditory experience.
控制系統：報告廳音響系統通常配備一個控制系統，用于集中控制和調節音響設備的各項參數和功能。控制系統可以提供方便的操作界面和預設配置，使音響系統的控制更加簡單和。
Control system: The sound system in the lecture hall is usually equipped with a control system for centralized control and adjustment of various parameters and functions of the sound equipment. The control system can provide a convenient operating interface and preset configurations, making the control of the audio system simpler and more efficient.
