low input or line input

hi all sifu2's here..
what is the function of low input or high input on my amp?
thanks..

low input = using RCA cables as input, the normal & better way
high input = using speaker cables, convenient for players with no rca pre-output, like OEM players, but sound quality not so good, also noise inducing sometimes
