The audio call and monitoring system is specifically designed for anechoic and shielded room environments, providing sound monitoring and intercom communication with strict adherence to EMC testing requirements. This system features advanced electromagnetic shielding, optical fiber signal transmission, and a highly immune pickup unit, ensuring clear communication without EMC noise interference and excellent immunity to external disruptions.

In typical EMC testing environments, standard audio communication systems often introduce unintended electromagnetic noise or suffer from poor signal clarity due to shielding constraints. The Audio Intercom System solves this challenge by providing a noise-free, interference-immune communication channel, allowing seamless coordination between personnel inside and outside the test chamber without compromising measurement accuracy.

Compared to conventional intercoms, our system uses full optical signal paths, EMC-hardened enclosures, and low-latency audio relays, which significantly reduce system noise and enhance voice clarity. Its modular design allows flexible integration with existing chamber infrastructure and ensures long-term reliability under high EMI conditions.
