The Roland DJ 808 has a defect that causes the Channel 2 Volume Fader to sink into the mixer making it unusable over time. It is a 4 channel mixer though and I want to be able to connect the 2nd video in Serato/Mix Emergency to the 4th channel on my mixer. Is there anyway to do that or any other suggestions? I can't Video Mix now because of this and feels like there should be some sort of way to fix it in Mix Emergency. Thanks, Mac
