LOOMING PROBLEMS
Loom wiring is an art in itself, and it is worth the time to get it
right. First, it is important to avoid ground loops (a looped wire acts like an antenna, picking up hum and electromagnetic radiation). Think of a tree. Every part of that tree is connected
to every other part, but only by one route. That’s how the total grounding picture for your entire studio should look. Don’t remove
the ground connection of your mains cable plug to reduce audible 50/60 Hz mains hum. Instead, you should disconnect the signal shield somewhere (one or several audio cables) in the signal chain.
