-The Single Volume Shared block controls level of the signal through slider. This block has single volume control for 'N' number of inputs. +The Single Volume Shared block controls level of the signal through slider. This block has single volume control for 'N' number of inputs. Connect an input signal and control its level with the slider. Optionally the slew rate can be adjusted in the range 1 to 23.
