在使用期间很容易就会受到一些因素的影响而导致问题的出现，比如说它的音频会受到干扰，然后就会出现失真、声音失调等问题，下面展开来讲讲吧。
Conference audio in use is easy to be affected by some factors and lead to problems, for example, its audio will be interfered, and then there will be distortion, sound imbalance and other problems, the following expand to talk about it.
失真大。它与设备的非线性失真和人为因素有关。其特征是声音嘶哑、破损、尖细刺耳，严重时会影响声音的清晰度、柔和度、明度丰满度和现场感。引起失真的原因是多方面的，如麦克风的灵敏度过高、摆放位置不合适、具有幻像电源的麦克风供电不正常、调音台的电平调整过大、均衡器的调整不适当、设备之间的阻抗不匹配等。
Distortion. It is related to nonlinear distortion of equipment and human factors. It is characterized by hoarseness, breakage, tapering and harshness, which will affect the clarity, softness, lightness and fullness of the sound and the sense of the scene. There are many reasons for the distortion, such as the sensitivity of the microphone is too high, improper placement, abnormal power supply of the microphone with phantom power supply, the level adjustment of the mixer is too large, the adjustment of the equalizer is inappropriate, and the impedance mismatch between devices.
电平不规范。在调试会议音响之前没有对调音台、均衡器等设备进行调校，造成信号电平过高或过低。另外，将不平衡的线路输出与平衡的线路输入直接连接，造成信号电平下降。
The level is not normal. The signal level is too high or too low because the mixer and equalizer are not adjusted before debugging the conference audio. In addition, the unbalanced line output is directly connected to the balanced line input, resulting in signal level drop.
音频响不匀。它与设备的频响指标和人为因素有关，如麦克风的指向偏离声源、中频和低频衰减太多、麦克风传输线过长等，都将影响声音还原的清晰度、层次感、丰满度。
The audio tone is uneven. It is related to the frequency response index of the equipment and human factors, such as the microphone pointing away from the sound source, too much attenuation of medium frequency and low frequency, the microphone transmission line is too long, etc., will affect the clarity, layering and fullness of the sound restoration.
声音比例失调。如果总控室、主会场、发言的分会场叁者之间的声音比例失调，就会影响其他分会场还原远程声音的平衡度，造成会议的整体效果下降。
Out of proportion. If the sound ratio between the main control room, the main conference room and the sub-conference room is out of balance, the balance of the remote sound restored by other sub-conferences will be affected, resulting in the decline of the overall effect of the conference.
混响延时不当。不同的会议类型和拾音环境对混响和延时的要求不同，因此要根据声学特性，调整混响和延时的参数。
Improper reverberation delay. Different meeting types and sound pickup environments have different requirements for reverberation and delay, so adjust reverberation and delay parameters according to acoustic characteristics.
