摘要
阻抗问题、电平问题、平衡和非平衡传输问题以及设备之间连接时的接地问题等是音频扩声系统中设备间连接的常见问题。如果系统设备间的连接不正确或不符合规范要求,不仅会使整个音频扩声系统的相关技术标准达不到要求,严重时还会损坏设备或导致系统工作异常,影响音频扩声系统的使用。针对这些问题进行详细说明,另外系统地分析音频扩声系统常见的噪声产生的主要原因,希望能为大家解决音频扩声系统问题带来帮助。
Impedance problems,level problems,balanced and unbalanced transmission problems,and grounding problems between devices are common problems in audio amplifying system.If the connection between the system equipment is not correct or does not meet the specification requirements,it will not only make the relevant technical standards of the whole audio sound reinforcement system fail to meet the requirements,but also damage the equipment or cause the system to work abnormally,affecting the use of the audio sound reinforcement system.In view of these problems are described in detail,in addition,the main causes of common noise in audio sound reinforcement system are systematically analyzed,hoping to help us solve the problems of audio sound reinforcement system.
