In recent years, HDMI matrix switchers have been widely used in school classrooms, large-screen display projects, multimedia conference rooms and other places. Is it necessary to have audio on the output of the HDMI matrix switcher? Many people say that it is necessary to bring, and some people feel that it is not necessary, how to choose?
HDMI matrix switcher as a transmission signal device, the input video is projected on the large screen, but there is no sound, so what if the matrix has no audio? Do you connect the audio cable directly from the console to the stereo? Or is it over the matrix into the audio splitter? We all know that the splicing screen does not have a speaker, HDMI high-definition line audio can not be used, we have to be equipped with an audio splitter, through the output of the matrix to separate the video and audio, but also to ensure the synchronization of audio and video, which is very troublesome, the cost is increased. At this time, if the HDMI matrix switcher has audio de-embedding, the HDMI matrix audio is output to the audio processor and then transmitted to the audio through the power amplifier to the audio can be output synchronously with the video, so there is no need to be so troublesome.
In summary, HDMI matrix switcher is still necessary with audio de-embedding, it can solve multiple video and sound synchronization output, in the process of use can help us save time and effort to speed up the efficiency of the completion of the work. HD video HDMI matrix with audio output function, but also reduce economic costs.
