Introduction The SPL Surround Monitor Controller (SMC) is a one-point analog volume control and switching matrix for system-independent 5.1 surround and stereo monitoring.
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 connecting 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.

Connectors The SMC enclosure is EMC-safe and effectively shielded against HF interference. Nonetheless, you should carefully consider where you place the unit to avoid electrical disturbances. The SMC and all devices to be connected should be turned off before connections are made or change to avoid damage to your speakers and ears.
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.
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 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.
