12 Volt Trigger

My amp and preamp has a 12volt trigger feature which I tried with my Furman power conditioner. For some reason it shuts off the amp occasionally. This setup concerns me a little. Any ideas what might be going on?
You may have a bad cord, or dirty connection.  See if reseating the plug and/or wiggling the cable does anything. If wiggling the cable makes it change, you have a bad cord.

Also, if your amp and pre both have triggers, you may not need the furman in the way.

I use the trigger feature from a HT processor to turn on the HT amps, and the subwoofer at the same time, but only because none of those have trigger features.
