What do you mean by 5.1 F/R, S/R, SW, FR, SR and C in the home theater? Hope expert pointing.
F/R, F/L is the front left and right vocal tract. S/R, S/L is rear surround left and right sound channel. C is a mid channel
You made a mistake, FL.FR means front or left, SL.SR is back around, C is mid, and SW is heavy bass.
