We are running a show on Jester and have had two instances of complete blackout on stage for about 2 seconds about 6 days apart during performances. There were no Qs at the time the lights simply went out and came back on for no apparent reason. There was no apparent power failure and the desk & monitor stayed live. The dimmers are 5 x Betapack 3 and would hold their level if the DMX signal was lost, so it must a clear DMX level change from teh desk I would assume. Is this simply an annoying hardware/software bug or something else, any ideas? This has never happened before in the 10 years we have had the desk. Could it be the current high temperatures and a chip on the way out? How feasible is it to find a fault like this?

We have several Betapack 3 purchased about 5/6 years ago. One rack has suddenly stopped working on the top two chanels i.e 5&6. The circuit breakers haven't tripped, the onward connection is OK., the DMX to the rack is showing as OK. The rack is driven by a 24/48 Jester and are on desk channels 11&12. Is their some internal electronics that can cause a pair of channels to fail like this? If not what is likely to cause this problem? All fine last week but would not play this morning. We have a show in the next couple of weeks and I need to sort this ASAP and I can't afford to loose a couple of channels on a heavy show.

Whilst there is a way to live edit a scene state as per the handbook. There does not appear to be any way to live edit a submaster state. Have I missed a way of doing this or is this bid hole in the way the Jester works. When working on shows that are plotted/edited during rehearsals this a real problem. Any suggestions.

What is the recommended approach to protecting the supply side feed to a betapack 3, the handbook mentions Type k MCB, does it work with the more usual type B and C? What is the position on use of RCD or RCBO, can they be used or are they not recommended for use with dimmers? Advice please.

We are in the process of buying a Jester 24/48 to replace our somewhat ancient Sirius desk. To get some early hands on I have been trying the Phantom Jester and have noticed that each channel flash button has an associated LED that does not seem to be mentioned in the handbook, what is its purpose, what does it is signify? I have also noticed that if recording scenes in programme and you need to look back at an earlier scene to check a detail and then scroll back to the next free memory, in would appear that the last recorded scene i.e. memory N-1 is present in that memory with the associated flash button LEDs flashing, these channels cannot be removed using the clear button and have to be removed one channel at a time by grabbing and returning to zero to get back to a blank memory in which a new scene could be recorded. Is this correct and how the "real" desk behaves or is it some anomoly of the Phantom Jester? Has anybody else seen this or is this just novice teething problems as it seems a rather odd design feature if it is by design.
