        無論舉辦何種會議,音響效果往往是決定會議質量的關鍵因素。會議室的擴聲系統、多媒體系統和設備錯綜復雜。想要獲得佳的會議音效,并不是簡單地堆疊麥克風、揚聲器、調音臺和功放。下面來講講多媒體會議音響的4個調試步驟內容吧。
        No matter what kind of meeting is held, the sound effect is often the key factor to determine the quality of the meeting. The sound reinforcement system, multimedia system and equipment in the conference room are complex. To get good conference sound, you don't simply stack microphones, speakers, mixers, and amplifiers. Let's talk about the four debugging steps of multimedia conference audio.
        檢查系統是否連接正確。
        Check that the system is properly connected.
        多媒體會議音響系統的正確連接是會議音頻調試的基礎。根據系統配置接線圖,仔細檢查線路連接和供電系統,預設好音響設備的功能按鍵,確保話筒供電充足。
        The correct connection of multimedia conference audio system is the basis of conference audio debugging. According to the system configuration wiring diagram, carefully check the line connection and power supply system, preset the function keys of the audio equipment, and ensure that the microphone has sufficient power supply.
        調整揚聲器的位置。
        Adjust the position of the speakers.
        主揚聲器應放置在會議主席臺的兩側,分體式揚聲器底部為中低音揚聲器,中間為中音揚聲器,頂部為高音揚聲器。如果兩側揚聲器的輻射區域相互呼應,音質會大大提高。請勿避免在音箱上放置盆栽、臺燈或瓷像,以免因音箱震動導致物體掉落而中斷會議。
        The main speakers shall be placed on both sides of the conference rostrum. The bottom of the split speaker is a mid bass speaker, the middle is a mid-range speaker, and the top is a tweeter speaker. If the radiation areas of the speakers on both sides echo each other, the sound quality will be greatly improved. Do not place potted plants, desk lamps or porcelain images on the speaker to avoid interrupting the meeting due to objects falling due to speaker vibration.

        打開功放,設置大電平。
        Turn on the power amplifier and set the high level.
        確認系統和硬件設備正常后,接通設備電源,打開功放,將電平調到大。在混音器指示燈上將混音器輸入增益設置為0dB,慢慢向上推混音器輸出推子,并根據揚聲器中聲音的音量調節推子,以達到佳音量。為保證佳調試效果,建議使用相位計檢測器檢查每個揚聲器是否同相。
        After confirming that the system and hardware equipment are normal, power on the equipment, turn on the power amplifier, and adjust the power level to large. Set the mixer input gain to 0dB on the mixer indicator, slowly push up the mixer output fader, and adjust the fader according to the volume of the sound in the speaker to achieve a good volume. To ensure good commissioning effect, it is recommended to use phase meter detector to check whether each loudspeaker is in phase.
        避免音頻嘯叫。
        Avoid audio squealing.
        多媒體會議音響廠家建議將混音器通道推子推到0dB,將麥克風放在會議講臺上,打開監聽輸出,找到導致麥克風嘯叫的頻段,并調整均衡器設置以消除它。麥克風應指向,避免對著發言者,必要時可適當調整會議講臺的位置。操作范圍必須小,這樣嘯叫才能保持在一個穩定的水平,然后再調整到更準確。
        The multimedia conference audio manufacturer suggests pushing the mixer channel pusher to 0dB, placing the microphone on the conference platform, turning on the monitoring output, finding the frequency band that causes the microphone to howl, and adjusting the equalizer settings to eliminate it. The microphone should point to avoid facing the speaker. If necessary, the position of the conference platform can be adjusted appropriately. The operating range must be small, so that the howling can be kept at a stable level, and then adjusted to be more accurate.
