# Chapter 2. Working with kmix

KMix usage is straightforward. Every mixer device that your soundcard provides, is represented by a volume slider. Mono devices have only one slider, Stereo devices have two sliders. You are able to merge the two sliders of a stereo device to a single slider. Additionaly there is a panning slider at the bottom of the KMix window.

The volume sliders show the volume of the selected device. Top is maximum, bottom is minimum volume. The slider can have three background colors:

- `Normal` No special situation applies to this device.

- `(Un-)Split` Show either one or two sliders. Only applicable to stereo devices.

- `Record Source` Set this device as record source. Only applicable to recordable devices.
