I recently purchased an XPA-2 which I have hooked up to my Pioneer SC-05 along with a 5ch Rotel RMB-1095. Both are connected with a 12 volt trigger. I have experienced issues with the trigger on the xpa-2, it does not seem to work consistently whereas my Rotel works flawlessly. Sometime the xpa-2 will turn on as it should with the trigger, other times it does not. When it does turn on and function properly it will randomly turn off after a couple of hours. The amp is not hot and turns on and functions properly after it shuts off so it's not going into protection mode. I have switched the inputs on the back of the receiver between the Rotel and Emotiva but that yields the same results. I was using the supplied 3.5mm cable which I thought might be the issue so I switched it out with a stereo 3.5 mm cable from radio shack, this did not work either. Is there anything else I should be doing to ensure proper operation?

Don't use a stereo trigger cable - mono only.
Sounds like your XPA-2 shuts down after awhile because its not receiving a signal (that's how its designed),...but if it shuts down after having turned on normally at first, but happens during active playback of something, then there's a problem.
I'd call Emotiva's customer service line if its the second issue...

My guess is the voltage is dropping too low below 12 volts as you are triggering more than one device. Best suggestion is to give Emotiva technical a call they will be able to tell you the tolerance.
Cheers

Thanks for the input. I was originally using the supplied cable which I assume is mono, I got the stereo one to try something different. It was suggested on another board. It shuts down while it's receiving a signal so it's not normal. I sent this info to support, hopefully I hear something tomorrow.

Also, if the voltage is dropping to low I wonder why it isn't affecting the Rotel.

A trigger output is like an amplifier or a power supply; it puts out a certain voltage and has the ability to deliver a certain amount of current. A trigger input, in turn, requires a certain input voltage to trigger reliably, and requires that the device triggering it be able to provide a certain amount of current at that voltage. If the triggering device can put out the correct voltage, but not enough current to drive the trigger input of the target device, then the output voltage will drop and the trigger won't work. In reality, most trigger outputs put out around 12 V and can deliver up to about 100 mA, and most trigger inputs (including ours) will accept a trigger voltage and current well below. There is not, however, an actual standard for either, so "disagreements" can occur. It is possible that there's something wrong with the amp, or that the receiver triggering it has some sort of issue where, after a few hours, it ceases to provide sufficient voltage to actuate the trigger. It will take a bit more troubleshooting to determine which... which makes this a support question. Also, if the voltage is dropping to low I wonder why it isn't affecting the Rotel. |

After speaking with support it looks like the unit is likely defective. They suggested that I send it back for repair which will take about a week but I'm not to happy with that. I'm going to play around with it this weekend and if I can't sort it out I will just return it. I can't accept a repair on a brand new unit.

Ok, looks like I may have solved the issue. I'm pointing the blame at the receiver. I connected the xpa-2 to the 12 volt trigger out on the Rotel and it looks like, for now, I have solved the problem. This was the last variable I was going to try before I returned it, funny how that works. Anyway, not that I have everything connected and running as it should I couldn’t be happier with my purchase. Next on the docket, a new receiver/preamp with Auydessey XT32.

You could try a stereo cable as some people have used it successfully. I'm sure the stores you listed have these.

Fairly certain I'm using a stereo cable in my XDA, and have been for a year. It's definitely something I've done before without issue.
You will have 12 volts between the Tip and Sleeve, just like a mono cable. The Ring in between will either not be connected to anything, or possibly grounded.

you can get a mono cable from several places. Amazon sells them. Cables to go makes them. There are others.
A stereo cable didn't work for me but I just got a radioshack 3.5mm stereo to mono adapter and it worked fine. With the stereo cable the only difference is that you have a center part of the connector that isn't being used. But that must be the place the amp is reading the signal so using the adapter just makes the correct contact point larger.
It also makes more sense that its your receiver's issue. I'm only using a 5v trigger myself and it's never been a problem.
