I just bought DDJ-SB Pioneer, currently using SDJ Intro, In setup some options in the Internal Mixer section is grayed out such as Cue Gain. How do i unlock this? I think the Cue volume is really low on this controller. My Master Out volume is turned down and my headphone volume is turned all the way to maximum & its as if nothing is coming through the headphones. When using my NS6 i cannot let my Cue volume pass 12 o clock else it would destroy my ears...... I fear when i go out in a club setting i will not be able to hear anything coming out of this SB headphone jack.
