Welcome

and thank you for choosing the SMC 7.1.

The Surround Monitor Controller SMC 7.1 is an analog studio monitor controller for 7.1 and stereo sources.

Each of the two balanced 7.1 Inputs and the two balanced Stereo Inputs can be routed to the balanced 7.1 Speaker Out-
put. The L/R signals of the selected input can optionally be routed to the Alternate Speaker Output. With the headphone
amplifier you can monitor the L/R of the selected input as well as single channels of the 7.1 Inputs.

The eight-ganged potentiometer controls the volume of all channels in the analog domain – no control circuits like VCAs
or digital attenuators are used.

The SMC 7.1 is built in high-quality analog technique, which ensures a linear frequency response up to 150 kHz as
well as an outstanding dynamic range.
