Speakers On
The SPEAKERS ON buttons enable each surround speaker output (L, C, R, LS,
RS, LFE) and the stereo pair to be switched on and off independently.
Tip: If you are not using a surround speaker set, you can connect two stereo
speaker pairs to the SMC. Simply connect one pair to the STEREO SPEAKER
OUTPUTS and the second pair to the SURROUND SPEAKER OUTPUTS L and R.
