Title: Feeding a 70 volt line with two amplifiers
Post by: Larry Stelter on February 23, 2018, 07:07:17 AM

Here is the picture. Over a 1000’ run with 20 plus 70v speakers with different wattages tapped. This has been operating for years. Unknowingly, the line got hooked up with an amp on each end which fed power simultaneously. Now some of the speakers don’t work. Can anyone explain what technically happened to the voltage in the line?
