Volume controller

YD-VOL03 volume controller is an electronic product that adjusts linear background music. It communicates with the central control host through RS-232/RS-NET/TCP protocol to form a centralized control system. It can realize the unique operation of three groups of stereo channel mute and volume up and down, suitable for demonstration hall, monitoring command center, conference room and other occasions.
★ Provide 1 channel RS-232 control interface, 1 channel RS-485 ID control interface, 1 channel TCP/IP control interface, communicate with programmable control host;
★ 3 sets of stereo channel volume controllers, which can control and separate independent control at the same time;
★ Input and output are connected by 5P Phoenix connector;
★Using American high-fidelity enthusiast PGA2311 digital volume adjustment chip;
★ Panel with high-brightness LCD display data and corresponding adjustment indicators;
★ panel with manual adjustment button control function;;
★ Supports input and output of L and R channels to support balanced and unbalanced connection;
★The host is powered by 220V/adapter;
