John shows one of the sound systems covering the Fargo Marathon 2023. This system featured three Electro Voice Everse 8 speakers and a Roland 707M DJ Controller. The controller and laptop were powered by a Jacker 880 watt unit, while the Everse 8 speakers were powered by Ryobi 300 watt inverters.
In past tests, the Everse would easily run 5 hours at the volume we were using for the day. The unknown is how long we would be at mile 25 as the last runners came to finish the race. I wanted to be sure we had up to 12 hours of runtime for this event and location.
We started this location at 9:45 am and wrapped up the sound at 3:30 pm. None of the inverters were fully discharged; the Jackery was down to 40%, Ryobi batteries were down to about 30%.
