What is the function of the GND output? Could this be used for a 12V trigger?

Thanks in advance

It’s a common ground path of some sort.(not sure) …. In a 12v install you will want to use the minidc…. I tried my flex in 12v and it worked excellent. Of course with the minidc dc/dc isolator…. 

you “could” send it to ground, I don’t think that’s what it’s for…..


i honestly don’t know what it’s for but being the outputs are pseudo-balanced (isolated) I would guess it’s for an amp that rejects that topology and the ground could be hooked to amp chassis to give a path….

this is a guess tho…… I’m sure someone will try to flame me for a guess @ultrasonic 

im curious as well, will you look in manual and see what it says and get back to us 



on a side note , the flex with digital outs or analog outs would make an amazing car audio head unit….  I really like the flex…. Lots of possibilities

I can't see how.

There is no mention of it in the manual.  So, what is the GND's function?

Then a chassis ground, for what I stated earlier is the most common use…. A lot of devices ground the return on the rca through its chassis. It keeps emi down and such… so if a component doesn’t accept pseudo balanced I bet two chocolate doughnuts that you can ground that to the component (amp, pre amp, downstream device) chassis and get a common path…. For lower noise….. or for certain power supplies….. just a ground path to chassis for low noise. 


some components you can ground through the RCA… if the ground fails you definitely don’t want it to reference ground through the RCA to the Mini DSP. It could potentially burn up the Mini DSP, so a ground path would be needed…. Etc etc
