How do I find a hidden short where the wires are buried and we have 39 speakers spread over 1000 ft. with 45 soldered joints?

Finding a hidden short in a complex setup like yours can be challenging, especially with multiple speakers and soldered joints over a long distance. Here are some steps you can take: 1. Visual Inspection: Start by visually inspecting the wiring path for any obvious signs of damage or exposed wires. 2. Use a Multimeter: Test each soldered joint and section of wire with a multimeter to check for continuity and potential shorts. 3. Segment Testing: Divide the wiring into manageable segments and test each segment individually to isolate the location of the short. 4. Check Grounding: Ensure that all speakers and equipment are properly grounded to prevent electrical issues that could lead to shorts. 5. Professional Assistance: If you're unable to locate the short or if you find it to be a complex issue, consider consulting with a professional audio technician or an electrician who has experience in troubleshooting such setups. Best of luck in resolving the issue!

Unfortunately I am the audio designer. I do 95% 8 ohm systems but I know I can’t use DC resistance because of the transformers. Was. Hoping you knew of a tool / proper meter.

​@@duanerandleman2456I apologize, unfortunately, we don't currently have any information on tools or methods for measuring impedance in transformer-based systems. However, If you find any, feel free to share them here!
