Genelec SAM™ monitors and subwoofers implement the volume control as a part of the DSP processing inside each unit. Decreasing the value makes the audio sample values smaller. This is done using proper dithering and with sufficient dynamic range so that there is no increase of distortion or noise at any setting of the volume control. Because of this, using an analogue volume control cannot bring any further benefit.

The command to set the volume to a certain level is created in the computer user interface software GLM and mediated into all monitors and subwoofer using the Genelec GLM control network. No audio signals travel on the control network
