Digital TV only plug the audio line does not plug the video cable, why the sound screen are not?
This is not a lack of power supply, but the line is too long working current slightly larger line voltage drop is very powerful, the end of the voltage is low. Not only low power, the signal level will be too low unqualified. General distance is relatively far, the terminal to load amplifier for the job. Or to a wireless forwarding receiver. These are more complicated. Professionals understand. Distance is not too far, you can switch to relatively thick cable to modify the USB cable to reduce the resistance of the wire, but this effect is limited cost is relatively high. Copper is expensive The greater the operating current, the more serious the line voltage drop.
The specification is not forbidden, but in practice little, because if it is a cable slot (bottom seal) from the bottom of the hole, the cable bending space can not wear a small cable, the cable bending radius is difficult to meet the specification requirements, the other wire tube is not good fixed , If it is a ladder bridge, the bottom can not open, must be from the side of the hole connected to the wire tube (or hose).
