ACH-AIO
Audio Conference Host All-In-One Server
- The device features uncompressed 48kHz audio transmission with shielded Cat5e cables, a 16-channel DSP audio matrix, 10-band EQ, volume/delay adjustments, and 5ms ultra-low latency for high-fidelity sound quality and real-time processing.
- It supports hybrid wired/wireless conferencing with 4,096 wired and 300 wireless units, 24 simultaneous speakers (16 wired + 8 wireless), role-based audio separation, and cross-domain synchronization for seamless mixed outputs.
- Redundant backup mechanisms include dual-host hot standby, ring network redundancy, and T-link fault recovery (5ms loop restoration), ensuring uninterrupted operation during cable/unit failures.
- Flexible I/O includes 16 Phoenix outputs (expandable to 272), RCA/XLR interfaces, RS-232/485 controls, 4 RJ45 ports, USB recording, and camera tracking via PELCO-D/VISCA protocols.
- Multi-platform control via C/S, B/S, 4.3″ touchscreen, Android apps, or web UI enables audio parameter adjustments, language switching (CN/EN/RU/FR), voting/sign-in, and role-based unit management.
- Advanced features include fire alarm integration, 63+1 wired interpretation channels, AP channel optimization, battery/WiFi monitoring for wireless units, and cloud/local configuration backups.
- Conference management tools support FIFO/VOICE/APPLY modes, agenda workflows (attendance, voting, scoring), partitioned phase control for 16 independent systems, and transcription system integration.
- System diagnostics include status LEDs, log management, firmware OTA updates, and unified monitoring via an audio management platform for networked devices (mixers, amplifiers, etc.).
