- Commodity name: K-81pro UHF One-to-One True Diversity Microphone
- 产品系列: Truly divided episode series
A professional, compact wireless system designed for small-scale performances—perfect for school events and engineering applications. It features dual-CPU microcomputer control: the entire hardware circuit is managed by a microcomputer, enabling advanced functions such as frequency selection, display, mute-lock activation, and battery-level monitoring—capabilities that are typically difficult to achieve with conventional models. Additionally, the system continuously detects interference signal strength in real time, allowing it to effectively avoid frequencies within the interference range.
