Overview
Wired and wireless conference convergence through one network host.
The Jistron JI20M is a Digital Convergence Wired Conference Host developed on a digital network architecture for converged wired and wireless conference applications.
It integrates AOIP network audio and TCP/IP networking, supports flexible addition of wireless microphone units, and includes machine-learning ANC noise reduction, AFC feedback suppression, camera tracking, voting functions, ring backup and three seamless audio backup paths.
Engineering
Key features
AOIP + TCP/IP networking
Network audio and management are integrated through AOIP and TCP/IP network architecture.
ANC noise reduction
Embedded machine-learning logic identifies noise and activates automatic noise reduction.
Three seamless audio backups
Microphone digital-analog backup, ring backup and host digital-analog backup are supported.
AFC feedback suppression
Environmental learning identifies feedback and activates AFC before system howling develops.
4.3-inch touchscreen
The front-panel touchscreen supports host management, settings and status display.
Camera tracking support
Works with a camera tracking host, panoramic presets and central control integration.
Voting & sign-in functions
Supports sign-in, voting and result projection to a large screen.
Operational functions
Control designed into the unit.
