xpa3 gen2 trigger in/out question

[skads187]

I think I may know the answer to this, but just want to confirm. 
I just got a new streamer all in one unit, in addition to my AV receiver. My AV uses the OUT to Trigger IN on the Emotiva, seems like the Emotiva only has one IR IN input. 
So for my new streamer, I guess there is nothing I can do to make the emotiva turn on when it turns on the same way my receiver does?
Im assuming using the OUT of the Emotiva to the IN of the streamer , will just do the reverse which is turn on the streamer if the xpa3 is on, which isnt what I want. 
I have a Harmony remote, but it could not find the xpa3, it found the xpa5 , but didnt seem to work, will see if I keep tinkering and see if I can get it to work.

Unless anyone has any good tips? thanks

These are not IR (infrared) triggers... they are simple 12 volt triggers. Put 12 volts DC (some will also take AC) on the trigger, at a supply of about 50mA, and the device will turn on. When the unit is on, the out will supply 12VDC at about 50-100mA to chain to the next device.

Oops yes sorry I new I would slip in IR by accident , I meant trigger In and trigger out. So Trigger IN on the emotiva is being used by the trigger out of the AV. So I Guess because there is no more trigger INs and only one OUT available , there is nothing I can do unless I can figure something out with the Harmony Touch remote?

There is definitely a way to get this to work. Probably the easiest way would be to build a remote turn on box. I don’t know if I am 100% clear what you are wanting to do though.

What I understand is you have three devices of interest: your AV receiver, your XPA-3, and a streaming box. You want to be able to trigger your XPA-3 when your streamer box turns on and you want to be able to trigger your XPA-3 with your AV receiver too. I don’t know if I entirely understand why you need this set up like this. Why not just hook your streamer box up to your AV receiver just like any other piece of gear?

More details may help. You can easily build a box with two relays each triggered by your a different device which powers on a small power supply and provides as 12v trigger out.

Easiest way is source, your streamer connected to the audio input of your AVR. Trigger output from AVR to Amplifier whether XPA 3 or 5 Trigger input. 12 volts 50ma input on the XPA amplifier using a 3.5mm mono tip ring sleeve male connector cable at both ends. Done and easy.

Ok yes, sorry, I should have been clearer, my streamer is also an integrated amp with no option of HT bypass. So I have interconnects going to a RCA switch one from the streamer pre-out and one from my AV  pre-out to the Emotiva.
and Yes, my AV is currently already using the Trigger IN on the emotiva and the xpa3 powers on when I power on my AV. I would like it to the same with the streamer/integrated amp. thanks

I thought this would do it, but reading the manual, doesnt seem like it:

Your requirements are so specific and unique that I doubt you will find something off the shelf that does what you need it to do.

You can build a solution though. My caveat here is that I am not an expert so if you have any questions you may need to consult the manufacturer and or an engineer to be sure none of your devices are damaged.

I think your best solution will be to build a remote turn on box. I built one that you can see here:


DIY 9.4.6 build

You will need to make some modifications. You will obtain two 1/8” mono chassis mount trigger inputs. You can use as many trigger outputs as you want. You will only need one if you just need to control the single amplifier.

From your mono inputs you will take positive (tip) and negative to a relay trigger. Since you will have two inputs you would wire these in parallel. The relay can switch AC hot to a small power supply, something that provides just 1-2a 12v out will be more than sufficient. One thing I am not sure about, given your trigger inputs will be wired in parallel and connected to the trigger out of your AV receiver and your streamer, I am not sure if sending 12v reverse current into one or the other would cause damage. You may have to wire a diode into this circuit to prevent this, but it may just be a non-issue.

From your power supply you can send 12v trigger out to your amp via another 1/8” mono chassis connector.
