I'm currently touring with 14 active DL.2's. At our show in Denver, Colorado yesterday, I had several "Filter" errors. As the day went on, 10 out of my 14 fixtures were showing errors! "How can this be?", I thought. I checked a couple of the HEPA filters, which didn't seem too dirty.
Then it occured to me... filter errors are caused by poor air flow (generally dirty filters)... but in this case, I think it was the high altitude. After all, we were a mile high and the air was quite thin.
Anyone else had this type of issue? Just thought I would pass this on.
All of the fixtures continued to work fine all day and for our show that evening. We have a show in Phoenix, Arizona tomorrow. Hopefully my "thin air" theory checks out and they will all be back to normal tomorrow.
