ACM-U11/U12 Microphone
Audio Conference Chairman/Delegate Unit
- High-Fidelity Audio & Network Integration: Utilizes 48kHz uncompressed audio transmission with 80Hz–16kHz bandwidth, PoE power, and capacitive touch buttons for noise-free operation, ensuring pristine sound quality and reliable long-distance connectivity.
- Role-Based Control & Management: Chairman units prioritize muting delegates, while delegates request speaking rights via PC software, supported by voice activation, speech timers, and sign-in controls through a multilingual web interface.
- Advanced Network Protocols: Operates via TCP/IP suite (ICMP, HTTP, UDP, TCP, IGMP), 100M PoE network transmission, and PING packet functionality for robust communication and device diagnostics.
- Customizable Audio Processing: Features 5-band EQ adjustments, feedback suppression, and voice sensitivity tuning to optimize sound for diverse speakers, paired with phantom power support.
- System Maintenance & Security: Enables web-based firmware upgrades, IP/MAC address sniffing for device identification, and centralized parameter adjustments (ID, sensitivity, EQ) via PC tools.
