I use an AUX male to XLR cable to play music out of a PA at gigs. This seems to work so far.
At a recent gig, the sound person mentioned that the cable I was using should not exist, and that I should pick up a direct box instead. So now I'm here, trying to find out why I should be using a DI box.
After doing some research on direct boxes, it looks like they allow a signal to travel over long distances with little resistance [which I assume degrades the signal]. Also it appears that DI boxes reduce humming through the PA.
Am I missing out on these benefits by using an AUX to XLR cable? Are there other benefits I might be missing out on by not using a direct box?
Here's an example of the type of cable I'm currently using: https://www.amazon.com/GLS-Audio-Cable-Stereo-Male/dp/B006LRPF7Y
