无线领夹式话筒在戏剧演出中获得了广泛的应用。本文拟就领夹式话筒在演出实践中遇到的问题和补救对策以及操作中的体验进行简要的阐述。 选择 UHF频段的无线领夹话筒工作频率高(300～960MHz),可用频率资源范围大,稳定性好。特别是现在锁相环频率合成技术的应用,将话筒做成频率可调形式,有效地清除了域外干扰。
Wireless lavalier microphone in theatrical performances has been widely used. This article will briefly introduce the problems encountered in the performance of lavalier microphones and remedial measures as well as the operational experience. Select UHF band wireless lavalier microphone high frequency (300 ~ 960MHz), the available frequency range of resources, good stability. In particular, the application of phase-locked loop frequency synthesizer technology now makes the microphone an adjustable frequency form, effectively eliminating extra-territorial interference.
