"RCA: weak signals, single ended, no transformer coupling. I find RCA to be the most fragile, but it works just fine if the cable is short enough and of reasonable quality."
"Each of the four connection types has maximum cable (link) length specifications. I would certainly try and stay within those specifications and again, the shorter the better, for any type of quality cable. That rule is iron clad. I would choose a 3 foot mediocre quality cable over a 10 feet highest quality cable.'
这个讲的是数字信号。
