Custom 12v trigger help

I have an RME ADI-2 DAC FS that i use as my DAC, DSP, and volume control. Unfortunately, it has no 12v switch.

My setup simply consists of ipad pro as source connected to the RME via USB, then from the RME balanced XLR out to my monoblock amps, then from there to my passive speakers.

The monoblock amps DO have 12v triggers.

I need to someone have a 12v signal sent from my RME to the monoblock amps’ 12v triggers when i turn on the RME.

Is there a ready-made part that lets me plug in the RME into it, detects a power draw which triggers sending of a 12v signal via a 3.5mm jack into my monoblocks’ 12v trigger jacks.

if no ready-made available, can a newbie readily build one?

ive seen something by Nile that does this but i think they dont sell them new anymore.. saw a couple on ebay used. problem is it requires a minimum 15w draw to send the trigger signal out its 3.5mm jack. the RME is a lower power draw device.

thanks in advance

thanks for your reply. which method of the two you shared would be most reliable and easiest to implement?

if i opt for the remote trigger method, would i have to have 2 remotes, one for each monoblock amp, or could i use one remote and a splitter to send the 12v trigger signal to each amp?

if i opt for the line level trigger, would i need two of those modules or just one?

i am not experienced with these kind of things so would need to figure out how to build them and wire them.

thanks in advance.

It depends on your preference, if you using the IR switch, the monoblocks can only turned on when the RME DAC switched on by using remote control.



If using audio switch, the monoblocks will turn on when audio signal presented, and turn itself off if no audio signal detected for max of 2 minutes.



In both cases, you just need one unit and have to build a simple circuit to make it work.

oh i see, so i can use my rme remote with the first option and program sensors to detect the power button on rme being pressed, then the sensors would trigger a 12v signal to my amps’ 12v triggers?

in this use case, if i turn off the rme with remote, the amps will trigger to turn off or go to sleep as well?

i think i prefer this to the 2nd option where the trigger to my amps is sent only after playback starts and that signal is detected.

hopefully i am understanding you correctly.

Thanks alot. two last things:

1. i am unfortunately not knowlegeable about even circuit basics. are there ready made parts i can out together? i can screw parts together and connect simple wiring, but no real solder experience or anything more involved.

2. my monoblock amps’ 12v triggers are via a 3.5mm jack/port on back. i would buy a trigger cable but would the device you diagramed supoort the same cable’s plug?

Another alternative

https://www.amazon.com/Stereo-1-Female-2-Females-Splitter-Changer/dp/B0009JFF7U



Plug the 12v adapter to the IR remote-control socket, connect the 12v adapter output to the 3.5mm splitter, use two 3.5mm cable connect from splitter to each monoblock 12v trigger input.

To programs the IR remote-control socket, please refer to its product desciption.



I hope this will help. 🙂
