Description

«Demonstration complex based on a multimedia projector (4000 lm) with a feedback system and a high-quality sound reinforcement system.
It is used to display any video information from the teacher’s standard PC, document camera or mobile PC connected to the system on a wall-mounted hanging screen. The sound of the video materials shown and the teacher’s speech are broadcast through a high-quality sound reinforcement system. The “feedback” system is used to conduct quizzes and tests during classes.
Electronic “Feedback” units installed at students’ workstations are used to enter and transmit to the teacher answers to tests and assignments, students’ personal codes, indication of testing modes and test results. An additional monitor displays current information about the students’ work, which allows you to adjust the presentation of the material as the lesson progresses.
