Play 1 and Play 2 Sliders, K, and L control the level of the files being played back. Note that these sliders operate in the digital domain. They amount to multiplication routines in the DSP which take the signal level and multiply it by a scaling factor between 0 and 1. This is important to note because using these sliders as a master volume control will degrade the signal to noise ratio. This is because using these controls lowers the signal levels while leaving the noise floor unchanged. These controls are intended to mix 2 playback files together, or to fade a file up or down at the beginning or end, not as a master volume control. Best signal to noise ratio will be achieved by setting Sliders K or L to maximum
