Before you begin IMPORTANT: Before connecting the SMC or any other equipment turn off all power at all units. It makes good sense to think about where you place your SMC before connec- ting it. It should be positioned so that you can easily reach it, but there are other considerations. Try not to place it near heat sources or in direct sunlight, and avoid exposure to excessive vibrations, dust, heat, cold or moisture. It should also be kept away from transformers, motors, power amplifiers

Operation Volume Control The volume is centrally controlled for all channels via a discrete six-level potentiometer with an extremely linear curve. The potentiometer controls the audio signals directly without any signal-degenerating circuitry such as VCAs or DACs, which tend to create tolerances between channels as well as distortion. The white circle with the potency scale can be easily marked using a pencil. Source Buttons Surround A/B and Stereo C/D The source buttons Surround A/B and

Operation Speaker Buttons The speaker buttons enable each surround speaker output (L, C, R, LS, RS, LFE) and the stereo pair output to be switched on (pressed) and off indepen- dently. 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.
