Hello all!
Moved to a new city 2 weeks before covid, and I'm finally getting set up to volunteer at the local community theatre. Like most small theatres, they have a mix of donated equiptment; kinda a 'lighting through the ages' museum exhibit. The system is basically a 90s ETC board going into a Dove DMX/AMX converter feeding racks of classic TTI modular dimmers.
Recently they started having a problem with flickering. When they dim a few lights, occasionally all lights will occasionally all flicker together. It doesn't happen all the time, and never seems to happen when lights are on full. We thought it may be isolated to a specific dimmer pack, but some experimentation has killed that theory. When it happens, its like someone is jiggling the master - all lights are affected. It will usually stop in a few seconds but may happen again if the lights are still dimmed. Between the pars and the small space, it seems that leaving the lights on full as much as possible has been the stopgap measure.
There is no power conditioning to speak of, but since it happens directly in response to dimming I am not sure it relates.
Any ideas on what I can start looking for? I feel pretty old, but I think I was born the same year the dimmers were made.... this is outside my experience.
