The next setting to adjust is the "Threshold". Threshold is the signal level at which the device begins to exert its compression effect. Adjust the Threshold until the compression effect is activating once the music signal is above "soft" and approaching a moderate level. Next you need to set the "ratio". Start with 3:1 (three to one) and go down and then up to see which setting it to your liking. … I've covered a lot of information so feel free to ask for more clarifications.
