I am not a theater pro but came across this board at a local auction and wanted to know if anyone can identify the exact model number or tell me where I can find the model #. I have searched a little and think it may be an ETC Obsession 150o, but although I have quickly figured out the functional difference between a 1500 and a 600, I have no idea whether they look different or not. Also any ideas on how to test it for functionality in AZ I would appreciate it. Thanks
