Introduction
It is an all-in-one audio-video processor with a built-in USB sound card supporting playback, recording, and conferencing (e.g., ZOOM, Tencent, DingTalk). It features 8-band parametric EQ with 5 filter options, a customizable user interface for managing up to 30 devices, and centralized control via RS232, RS485, and UDP for seamless system integration.
