itc TS-0400M

Built on a gigabit network audio transmission architecture, all core components use domestically produced chips, and can connect to digital wired microphones, digital wireless microphones, and analog microphones; it supports multi-channel concurrent processing, enabling 128 microphones to be turned on and speak stably at the same time.

With an ultra-large system capacity, it supports simultaneous access and management of 65,535 wired conference units and 300 wireless conference units; it also supports simultaneous participation of 65,535 conference units in the meeting agenda (check-in, voting, services, etc.) and speech control.

It features highly integrated DSP audio processing capabilities, including ducking, automatic gain control, equalizer, compressor, expander, automatic mixing, feedback suppression, echo cancellation, ambient noise reduction, matrix routing, EQ adjustment (supporting 8-band, 10-band, 15-band, and 31-band EQ adjustment), volume dB adjustment, and delay adjustment.

Equipped with professional-grade audio processing capabilities, it achieves a low latency of 2-3 milliseconds across the entire audio processing chain, from conference unit pickup through ducking, automatic gain control, equalizer, compressor, expander, automatic mixing, feedback suppression, matrix routing, EQ adjustment (supporting 8-band, 10-band, 15-band, and 31-band EQ adjustment), volume dB adjustment, to audio processing output.

This industry-innovative system adopts a "one-machine-multiple-zone" and "multi-machine interconnection" approach. A single host can be divided into eight independent conference zones, each with its own dedicated microphone and audio channel. Simultaneously, conference functions operate independently without interference, including check-in, voting, and priority settings, ensuring spatial isolation and independent operation. Furthermore, the system supports flexible audio interaction modes, enabling cross-zone two-way communication to meet the needs of group discussions and centralized training sessions. Multiple hosts can be interconnected via a network for unified management, significantly improving resource utilization and making system deployment and expansion more flexible and efficient.

Multi-mode meeting management and high-concurrency processing: The system supports the creation of 8 independent meeting rooms and can flexibly switch between 7 speaking modes for each meeting room, including first-in-first-out, normal mode, request mode, voice control mode, last-in-first-out, free discussion and queuing mode, to adapt to different meeting formats.
