Selection method of projector audio line

First of all, the choice of projector audio cable should be based on the type of projector audio interface. Common interfaces include 3.5mm earphone interface, RCA interface and HDMI interface. Secondly, the equipment connected with audio source, such as PC, notebook computer, DVD, stereo, etc. , you should consider choosing the corresponding audio cable interface type and length. If the projector is far away from the sound source equipment, you can choose a longer audio line, but you should pay attention to the limitation of signal transmission distance to avoid signal interference and reduce noise. At the same time, pay attention to the wire and production process, and choose the audio wire with better quality to ensure the stability and clarity of sound quality transmission. Finally, you need to pay attention to the model and version of the audio cable to ensure compatibility and stability. For example, the HDMI interface needs to select an audio cable supporting HDMI2.0 or above to support higher audio transmission quality and function. When choosing the audio cable of the projector, we should consider comprehensively according to our own needs and equipment conditions, and choose the audio cable that suits us, so as to obtain a better audio-visual experience.
