TV set-top box has three lines, red and white, respectively, on behalf of what?
and now inserted in the AV2 ridicule tank Intuit anti-boudoir fruit , Because the video line plug is not broken, only inserted two audio, but transferred to the av2 nothing, is that so? I thought that only plug the audio line should have at least a voice ah The Do not know now is the set-top box is also broken? The The
Should be the line of the problem bars, if the same speaker or the same is the interface of the problem
Red and white is the audio line! Yellow is the video line
Certainly not, the specification clearly stipulates that different voltage levels of the cable can not be laid with the trunking. In actual use, with the partition can be separated, or high-pressure wire to wear pipe protection, do grounding protection. There are two reasons: First, because the high-voltage cable is a distribution line, easy to have lightning surge voltage, fault burst will spread to the rest of the trench, co-channel, co-cable, resulting in the potential risk of accident expansion. Second, the high-voltage cable electric field strength, low-voltage cable if the secondary protection cable, the external magnetic field interference, temperature interference will be more sensitive, so in order to low-voltage cable internal current and voltage characteristics, generally do not allow trenching, co-laying. High-voltage cable: high-voltage cable is a kind of power cable, is used to transmit 10KV-35KV (1KV = 1000V) between the power cable, and more used in power transmission of the main road. High-voltage cable product implementation standards for the GB / T.2-2008 and GB / T.3-2008.
