I thought I would report back from my previous threads. The M7CL/d&b Q gig was a wash out from the digital link point of view. Due to the incompetence of the PA company (maybe I am fussy, but I think they should send all of the equipment in time for the fit up, plus all the wires to join it up) I ended up with very little time to troubleshoot. It did not work first time and I had to go back to analogue. Post mortems revealed that the digital stream is pretty fragile and long runs (75m) are dicey even with proper 110 ohm cable. As far as we could tell the AES output card was working in the desk but absolutely nothing was arriving at the D12 amps. Next time, maybe.
Also there was digital fun on my job using the Outline Butterfly system. The speaker system, supplied by Brit Row, worked fine. We had a bit of tweaking to do as they had never flown the cardioid subs before and The Roundhouse is not the most acoustically friendly venue.
I was using a Digico D1 (lovely sounding desk) via optocore into the Brit Row Dolby lake processors. By the time we got to the end of the fit up day (it was for TV, lots of set and lighting) the system, which had sounded fine at lunch time, was awful. It turned out that the D1 clock was freewheeling whilst the Lake was locked to the optocore. This meant that their time clocks had drifted apart, destroying the sound. Locking everything to the optocore solved the problem. This is all new and scary for me, with a whole new range of interesting chestnuts to deal with, but the optocore certainly solves the problem of getting a digital signal to travel any distance. It helps keep the interest up!

Then of course we realised it didn't come with ANY cables, apart from tons of 16A power... oh and some 5 pin DMX strangely. On the phone to another hire company... just about got it all together in time :S
