For starters, I've been lurking here for years. Haven't had a need to post, yet, because so far just searching the forums has always been able to answer my questions.
I'm adding a 12v trigger to the old Ashly FET-1000 that currently drives my subs. I've ordered a 25A solid-state relay to do the job, along with a heatsink (since it didn't add much to the cost), and it seems like a straight-forward thing to integrate it into the amplifier itself (there's lots of room inside the chassis).
My question is this: Once in awhile, I pull the Ashly out to do actual pro-sound things. And in that world, 12V triggers just don't happen: You show up, plug the amps in, turn them on at the appropriate time, and that's that. Meanwhile, at home, I really would rather have the amp (and its noisy fan, and the power draw) off when not in use, hence the 12V trigger from my AVR.
In order to do both things, I intend to use the Ashly's existing front-panel switch to bypass the SSR. Logically, it will do exactly what I want (it's just an OR gate), but in terms of practicality I'm just not sure since I've never played with SSRs before.
It seems to me that the SSR will always see either 120 or 0 volts across its output terminals, regardless. And to that end, it seems that it will be happy (ie: not catching itself on fire) in any configuration.
But I just want a second opinion before I wire the thing up.
