专业无线传声器在大型演出现场抗干扰技术

Anti-interference Technology of Professional Wireless Microphone on Scene of Large Scale Show

介绍了在演出现场音响技术人员配置和调试无线传声器系统时,必须掌握的抗干扰技术,干扰保护比;给出了基于抗干扰技术进行现场环境测试,严格配置各个无线传声器使用的频率的具体方法,从而防止出现同频干扰、带内干扰和邻频干扰,确保无线传声器传送的音频信号具有高信噪比。

The paper is conferred around the introduction of the anti-interference technology and inference protection ratio that must be mastered by the audio technicians on the scene in configuring and debugging wireless microphone system; some specific methods were given on the basis of the scene environment test under the anti-interference technology and strict configuration of frequency used by each wireless microphone so that the same frequency inference, in-band interference and adjacent frequency interference could be prevented so as to ensure audio signal with high signal-to-noise ratio transmitted by the wireless microphone.
