For example, during a dance recital last year we were going to a blackout and we had a number of instruments remain on despite every channel being at zero, the master being at zero, and the presets being turned off. The TD I work with calls this 'ghosting' though I do not know what it is caused by. Has anyone else experienced anything like this?
The only time I have seen this happen is when the optocoupler controlling the triac failed. As such, the channel remained illuminated despite any attempts to dim it
