Audio and video all-in-one machine

Descriptions

The multimedia management host is a device that integrates audio, video and control. It replaces the use of multiple single-function devices to form a system and avoids the challenges caused by complex integration and system reliability.

This compact 2U multimedia management host features powerful audio processing and excellent video quality, and supports 4k seamless video switching, HDMI 2.0 and HDR.

It is a flexible solution that is easy to install and greatly simplifies the system architecture and subsequent technical support and maintenance costs of small and medium-sized conference rooms, training rooms, and multimedia classrooms.
