Check for these warning signs: Dents, cracks, or scratches on the enclosure Loose, wobbly, or broken connectors Stuck or unresponsive switches and knobs Rattling sounds when you shake the box Burn marks or unusual odors (indicates electrical damage) Pro Tip : Inspect your DI box before and after every use
