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 moni- toring. Designed to provide only the necessary functions with excellent audio quality, the SMC offers a uniquely cost-effective stereo and surround speaker and source management solution for essentially any audio application: •...
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.

Connectors The SMC enclosure is EMC-safe and effectively shielded against HF interfer- ence. 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.
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.
Warranty All SPL products come with a two-year manufacturer’s guarantee against defects in material or assembly from the date of purchase. End users are supported in the two-year guarantee through their distributor or dealer. In such cases, please contact your dealer for full guarantee condi- tions and service.
