Mal P Posted August 19, 2014 Share Posted August 19, 2014 Hi folks, It's been a while! So I've got an ME14 pre-amp driving an Odyssey Khartago pre-amp and it's a pain to manually turn on the amp everytime. The ME14 pre-amp has a 12v DC out that's activated when it's turned on. Is there a commercially available power strip or some equivalent relay that will provide power to the amp when it detects the 12v trigger? A search on the web didn't yield much results although there was a Monster power strip available a few years ago with U.S. voltage. Thank you!

surprisetech Posted August 19, 2014 Share Posted August 19, 2014 There are DIN-rail mount relays that switch 240V and have a 12V coil. However, having one in a suitable enclosure with 240VAC Input and Output/s will require a suitably qualified electrician to get involved. Link to comment Share on other sites More sharing options...
Guest myrantz Posted August 19, 2014 Share Posted August 19, 2014 I'm using a old PS Audio Quintet that has 2x12V triggers (3 zones, settable to instant or delay)... Not sure if the newer Detect has this. But IIRC the re-generators do (P3/P5/P10).. The old Belkin power centres (End of line) also has a 12V trigger in. If you want something quick, probably get those master/slave power strips from hardware shops... Plug your pre to the master, and when it's on, all the salves sockets will be turned on (and vice versa).. Something like this. (Just a random google, not a recommendation). The downside of this setup is you can't power up/down your slave components sequentially (like the equipment in the first paragraph).. Secondly, the master equipment must draw a certain amount of current for this to work (details should be in the packaging).. Also... pre amp to pre amp? (I'm thinking you mean poweramp?).. 1 Link to comment Share on other sites More sharing options...
RockandorRoll Posted August 19, 2014 Share Posted August 19, 2014 the power board i use has this. It also has the ability to turn of power to the devices from the mains when shutoff. Its a Belkin PF60. They used to be sold in Harvey Norman but were discontinued not long ago. You might be able to find some on ebay though Link to comment Share on other sites More sharing options...
Spizz Posted August 24, 2014 Share Posted August 24, 2014 There are 2 options that are currently available that I know of. One is the Monster Cable Rack Mountable HDP1750G w/12v trigger input- http://www.ehifi.com.au/brands/monster/power-and-surge-protection/monster-greenpower%E2%84%A2-hdp-1750g-powercentre%E2%84%A2.aspx or Mark over on DTV Forum was doing one late last year for around the $120 mark- http://www.dtvforum.info/index.php/topic/141262-eoi-12v-triggered-mains-outlet/#entry1915885 I purchased the former for my Active speakers, but am yet to set it up.

MooneeBeach Posted August 24, 2014 Share Posted August 24, 2014 (edited) I recently bought a $30 power board from Bunnings that senses when you turn on the component connected to the master socket. I have it set up so that when I turn on my amp it automatically turns on the DAC, USB converter, etc. Edited August 24, 2014 by seaninbrisbane Link to comment Share on other sites More sharing options...
Lashes Posted May 15, 2020 Share Posted May 15, 2020 @seaninbrisbane, I know this is a super old topic. Do you recall the brand/name of the power board you got at bunnings? I’m looking to track one down. Link to comment Share on other sites More sharing options...

stereo coffee Posted May 15, 2020 Share Posted May 15, 2020 (edited) Topics like this need some qualification as to the actual requirements. 12v as example can be 12v AC ... or can be 12v DC .... a power board is a totally inappropriate product to think of finding either, as power boards are 240v AC devices. If you need 12V DC Jaycar stock a nice plugpack https://www.jaycar.com.au/12v-dc-2-5a-power-supply-7dc-plugs/p/MP3490 which is still not correct for a relay as some current limiting and a snubber diode for the coil are essential. You really need to look at the schematic diagram for your product, to assess it has a diode fitted for its internal relay. At a minimum you will need a 12v DC regulated supply and a 100 ohm resistor for each trigger supply positive and the correct cable attachment. Tidying this up, use some casework, and arrange a 2.1mm fitting for the incoming supply, and 100 ohm resistors to each branch you need a trigger to be used with.

It's in the title 12v AC when rectified is 16.97 V DC ......to convert AC to DC / .707 the title cannot assume 12v is either AC or DC, unless amended to qualify which it refers to.

stereo coffee Posted May 15, 2020 Share Posted May 15, 2020 1 minute ago, Bunno77 said: maybe you should google 12v trigger It is informative to explain the required voltage requirements, vague terms have no place in proper electronics expression. on one hand the title has explained 12v ( rather than 10.23 V, but then enters or slips by not qualifying the voltage value as AC or DC) . The title needs to explain which by stating which. Science demands terms be used correctly as it is tied directly to physics. Perhaps if we accepted being vague, we rely more on cognitive science and have different interpretations of everything around us, We could well ask if you accept that cognitive science applies in this case, what is its definition of voltage ? Neither AC or DC then slopes towards vagueness, which fails to assist others wanting proper explanation. Which leads back to voltage when used as a term has to be expressed correctly. the two common terms are direct current DC , and alternating current AC https://en.wikipedia.org/wiki/Vagueness " The problem posed by vagueness is to explain its particular kind of indeterminacy. Does vagueness render large portions of ordinary language meaningless? Likely not, since we frequently use vague language to great effect in ordinary discourse. If not, what is vagueness, at the level of predicate logic? How is it to be modeled without contradiction, and without sacrificing too much of classical logic? Is vagueness semantic, metaphysical or epistemic? Vagueness has in its own right reaped the attention of an extensive literature. In addition, vagueness is a topic that touches many other questions in philosophy, linguistics and cognitive science, not to mention ordinary conversation."

There may well be equal vagueness applying to one trigger vs another, some may be AC or others DC, The thread needs to question this vagueness and provide valid information, and not resort to promoting vague terms, exampled by using voltage but not saying if its DC or AC . What I can help with, is that most circuitry associated with relays is DC. Link to comment Share on other sites More sharing options...
Bunno77 Posted May 15, 2020 Share Posted May 15, 2020 just try googling it. might surprise yourself and bring light to the vagueness of asking for a 12v trigger on a HIFI forum Link to comment Share on other sites More sharing options...
stereo coffee Posted May 15, 2020 Share Posted May 15, 2020 No, as that is just being vague allowing many different interpretations, ..rather what is needed is correct information. The title needs amending to say if its DC or AC, quite simple. OR if unknowing of which , removing its reference to 12 V Link to comment Share on other sites More sharing options...

There may well be equal vagueness applying to one trigger vs another, some may be AC or others DC, I quite agree. But you've only scratched the surface at how vague the title is. Let me assist: "Power Strip" needs to be defined: I mean is it their home strip or their clash strip Also the word power doesn't specify what sort of power. Is it electrical, mechanical or perhaps political And we are making the big assumption that the "12" in 12V is based on the decimal system. If it's actually something like octal base then we could get into all sorts of trouble. 2 Link to comment Share on other sites More sharing options...
