No big projects right now, I'll be building a couple little doors for the attic accesses soon though. I finally got tired of having to switch on and off manually the EP4000 for my subs so PROJECT TIME!!!!
I've asked around about switching off pro gear with 12v triggers but most folks suggested switched outlet or outboard box. That is too bulky as my rack is already very crowded. So I came up with an internal solution for the EP4000. Basically I wired in a 12V relay after the main power switch and mounted a 1/8" jack to accept the 12v trigger on the back of the amp.
3.5mm jack and Relay and through hole board:
Removed this foam not real sure why its there..... Amp fan runs much quieter and slower with it out......
Shot of relay after switch with 12v trigger current coming in on the twisted blue white pair.
Nice finished look. The way it should have come from the factory.
The relay mod works well, I did have to adjust my trigger delay for the amp to keep away the dreaded thud when all the other gear powers up but that was a simple setting in the projector.
I'll never have to flip the amp switch again unless I want to and that is worth the time it took to disassemble the rack do the mod and put it back together.
Total cost... about $10 for the 1/8" jack, relay, and board. The rest I already had but it did take about 4hrs.....
