I've been making music on synths, drum machines, bucketts and my computer for about 15 yrs now yet I've got no formal training. I realize that for long cable runs, it’s best to use balanced cables to reduce noise and grounding problems. What about cable runs (15 to 25 ft) to gear with unbalanced outputs like vintage synths? I think DI boxes are an option but I also understand that the 'affordable' ones color the sound in a negative manner. Additionally I've got about 20 channels I need to do so with on a tight budget. Is there a 'cheap trick' to making cables to convert bal to unbal while maintaining they’re functional integrity? Perhaps a DIY project of some sort? I've searched and surprisingly; not much on this. Maybe I'm the only one that doesn't know... :-? THANX!
