Stereophilus Posted July 4, 2021 Posted July 4, 2021 Provocative title, I know. I am a happy user of 12V triggering from my Preamp to my monos. Works fine. However, I am browsing the internet, and I read this from a reputable audio manufacturer… “The optical Audionet Link connection is implemented to power on the Audionet MAX by remote control. This leads to a galvanically isolated connectivity without sound affecting cable connections. We do not use 12V trigger connections to avoid sound diminishing capacitive and electromganetic effects as well as secondary voltage injections. It is alternatively possible to switch the MAX on simply via the input signal, e.g. for the compatibility with third party devices that do not provide Audionet Link. Please refer to the user’s manual for the set up.” So, is this a thing? Or is this another audio furphy?
Guest Posted July 4, 2021 Posted July 4, 2021 Wow, with remotely positioned mono amps I've been using triggers for years. I must be doing it all wrong 1
Steffen Posted July 4, 2021 Posted July 4, 2021 All trigger receivers I’ve seen the schematics of were galvanically isolating, via opto-couplers. I believe this is the standard way of going about it, but I don’t know for sure.

Andy Haha, not at all, as we all know… The quoted section caught my attention as it is from a company producing very high end amplifiers, so, what I would think to be a reputable source of information… 12 minutes ago, Steffen said: All trigger receivers I’ve seen the schematics of were galvanically isolating, via opto-couplers. I believe this is the standard way of going about it, but I don’t know for sure. So maybe the “Audionet Link” optical trigger is just a variation on normal then? And if “normal” is opto-couplers on the trigger input, then the 12v trigger line must be a potential concern as stated?
TP1 Posted July 5, 2021 Posted July 5, 2021 I think a lot depends on the design and execution of the trigger. Most gear that can be turned on by remote control has some form of relay switch - which us what a 12v trigger is essentially. I use amplifiers with 12v triggers in the theatre room and have tried them with the Audiophonics 12v trigger adapter as well as without any , TBH, I couldn't pick any real differences in sound with or without the triggers , but to be on the safe side, I ended up building my own 12V triggers with 40 Amp capacity just in case the 10 amp rating of the Audiophonics unit could cause issues. 1
