Hi 'y'all !!
So, this past weekend, my girlfriend, her son & his wife put together and set off a 20-minute fireworks show on the son's dad's country property.
Along with the show was a video on a portable projector and screen describing the writing/meaning of our national anthem followed by many musical cuts played to coinside with the fireworks. While I supplied the amp and preamp (Carver C1 and Carver M1.5), the son provided his MTX TP1200 (yuck) speakers that he had since high school 17-years ago. The Carver equipment is probably from about 1983-ish and untouched internally.
Here's what happened: We were playing this system nearing max output for the amp for about 4-hours while we set up the show. The source were MP3 files on my Samsung S9 phone. Things were playing fine the whole time but I was still checking the amp for heat. Yes, it was getting warm but nothing you couldn't touch.
When it came time for the show, the son connected a laptop that synced the music and video to the show. About 2-minutes into the show the amp goes into clipping mode and stayed there till I turned it down to let the amp reset. It did this 2-more times and each time I turned the volume back to be a little less than where it was before. The third time I just turned down the bass a couple db's to conserve some output energy needed.
So, my question is; did the clipping happen because the output caps in the amp are 40+years old or more likely from the laptop's audio output set too high?
I want to use this same setup next year and I was already thinking of getting amp refurbished and hot-rodded to 520wpc at https://nelionaudio.com/ . I use this same amp in my office at home but nothing near this kind of play it saw a couple of days ago.
For giggles, here's part of the finale with the son's wife's sister practically having an orgasm. Ya see, that family came in from Arizona to Ohio to see this. And Arizona just doesn't have stuff like this, I'm told.
