I read in a few threads that some people said you can use a 1/8 3.5mm stereo jack instead of a mono, cable as a 12v trigger. Is this true or will I blow up my Krells as I haven't found a mono 3.5 cable yet here in France
12v trigger can I use a stereo cable 3.5mm 1/8

Yeah, Its definitely 12v. Actually I am using the C1 with the Krells now as I have 2 cables. I bought 2 more stereo jacks as I couldn't find the mono for hooking up the rcd 1072 Rotel cd player which only shuts off with a 12v trigger.
post note: I tried a stereo jack and it works fine. I think its better to have it turn on and off with power than to "sense" the signal, because if you happen to flip thru sources for a moment you shut off the cd and have to start all over. Just having it come on and off with the system is fine.
Thanks again Peter

I found that a 3.5mm stereo adapter to a 2.5mm jack will not work with the Parasound A51. It definitely requires a 3.5mm mono to 2.5mm mono connector.
This brings up another point which I don't understand. Why does Parasound use a 2.5mm trigger jack on the A51 but most pre/pros and receivers use the 3.5mm jack. Including Parasounds own C1 and C2. I don't get it. What's the reasoning behind that?Mitch

Hey, good question. Never thought of it--and have no idea what the answer is.
Maybe it's like those air filters on Apollo 13--the LEM has round filters, the moon lander has square filters. (or was it the other way?)CHRIS

I don't know but I had a heck of time trying to find an adapter. Rat Shack was clueless. Parasound is sending me one 2nd day air so I can finsih auditioning the A51.
Chris,
How are you turning on your A51? Manually? Audio Signal? I found the audio signal to be to finnicky. No matter what I set the adjustment knob to it either wouldn't turn it on reliably or it would shut off while I was watching Sat TV.Mitch

Any kind of stereo-to-mono wiring is likely to fail, because these adaptors sometimes short the left+right. This does not work. If a stereo plug is used, the left channel is positive trigger [+] and the right channel will be the same as the common, i.e. negative trigger [-]. If left and right are shortened by the adapter, you have a problem :B

Mitch, I've got the A21 daisy-chained to the A21 that goes to the autotrigger. It works absolutely fine--I've never had a single problem with it. Both turn on when I turn on the C1, and shut off when I shut it off.CHRIS

Do I have that correct? I'm just trying to gage if anyone is using the auto signal sensing feature and having it work consistently and reliably.Last edited by Chris D; 26 May 2016, 22:00 Thursday.Mitch

Whoops... you're right, I had a couple typos. Using your sentence again,
I'm using the 9-12V DC trigger from the C1 to the trigger IN on my A51 which has a trigger OUT wire going to the trigger IN wire on my A21.CHRIS

How much do I win for digging up a ten year old thread?
I was actually googling 12v trigger stereo vs mono and found this thread. I know it's the Parasound club but I've got a Denon 2307CI -> Emotiva XPA-5 amp and it's strange, everywhere I look people say use 1/8" mono -> 1/8" mono. That doesn't work for me but stereo does. So the question is, what is going on here? Are all the brands different or something? I mean it's a simple voltage on/off so it seems like it shouldn't matter.-Chuck- Bottom

No offense to Roy Rogers, but I hate triggers! LOL.
I have always somehow got by and made this work Chuck, but I am not sure what to tell you here. Watch out, sometimes Kevin whacks people that dig up old threads, lol. JK.Doug

Ah, I wonder if Denon did that as well. Though mine does have two separate trigger ports. It could be the Emotiva too, I'm not sure which. All I know is mono doesn't work and stereo does, just thought it was strange. That kinda implies that it's *only* using the middle part of the connector.-Chuck- Bottom

I guess it depends on whether the company uses a mono or stereo jack for their trigger outputs, and how they wire them up.
Hmmm... <clicky> admin control panel <clicky> impala454 <clicky> move to spammer group <clicky> wait a sec, how'd he get 3,794 posts? <clicky> Wait, he's an ultra senior? Maybe not a spammer? <clicky> well, dodged a bullet there. haha J/K.
Actually when I clicked this thread and saw posts from 2005, I went to the end just to see *who* did bump it back up. Sometimes spammers do just that, because they're idiots. They think they'll slip under the radar, but in reality it just makes them easier to spot.- Bottom
