In the past there have been some stupid little issues. Sometimes when powering up it will go into a little lock up mode and you have to cut power and try again. There have been issues with the wordclock but that isn't really an error so much as it not playing nice. The mute buttons and a few other buttons have gotten increasingly difficult to push, one or two don't work at all and about 8-10 others are difficult to push. You really have to press hard and wiggle it a little bit.
Which sucks for theatre where I may be muting as many as 20 channels at once, trying to do it four at a time and then you have to go back and get all the ones that didn't take. By now the next scene is happening. It takes a little bit of planning ahead.
So now for the failure that happened last night. The console has 24 analog inputs and 24 channels of ADAT input, in our system there is an outboard ONYX Pre adding 8 channels of audio that end up on the digital layer.
All of the analog channel processing is built into the console but to use the DSP for the digital channels you have to use an expansion card (which we have).
Well last night we lost almost the entire orchestra (except for keys and bass) which just happens to be what we have on the digital layer. It's a small space and the volume is pretty low so it took awhile to figure out what all was not working. Looking at the channels the meters are going fine, but soloing the channel or the sub group reveals that the audio isn't passing from any of the digital channels.
After lots of troubleshooting (during a show with 21 wireless systems mind you) we discover that the problem is either that the gate is not opening (even though it is supposedly not in the signal chain, has a range of 0 and a threshold of minus infinity) or the DSP is simply killing the audio somewhere between the metering and the compressor section (solo is post dynamics and EQ).
During a break we manage to get the system shut down, pull the card out and re-seat it and it works for another 20-30 min and then kills the digital channels again.
Ugh Tech Week Sucks.
So tonight we have a Mackie 1604 feeding those extra 8 band mics into our last analog channel on the TT24 (which has a non-working fader so you have to use the touchscreen and knobs to adjust the fader)
Not optimal, but we need those band mics.
