How a birthday party looks like #2

Thought to share some technical details, hope you find it interesting. Won’t go into deep technical explanations, rather just give some general idea how we use some of our gear during these two days.

Studer, Lexicon, TC and Pro Tools

The Studer Vista8 serve as a live broadcast and remote gain console. On the first two layers we mix the current show with 82 inputs from the big hall. If necessary, we can remote control the Studer from the other studio, but honestly you need to constantly check if the remote is working fine, because it’s not the most stable software…
The Lexicon 960 serve as a four engine reverb, while the TC system 6000 serve as a two engine reverb, a multi-band mid/side compressor and a limiter on engine four. All the channels goes into a Pro Tools HDX2 system which also records two complete broadcast mix, one is processed (quasi-mastered on-air) the other is unprocessed.
If it is necessary, the Pro Tools system can also serve as a main mix system with a S6 surface, recording the multitrack, the mixed on-air outputs while recording the mix automation during the performances. We have a few detailed template session for this.

Where it all comes together

The centre of the whole multi-room system is the Direct out technologies m1k2, which is a very clever routing matrix for 1024×1024 audio channels. Although the whole building operates at 24 bit 48kHz, if we happen to have any additional equipment which operates at any other sampling rate, this system is able to handle that with its poly-sync feature.

We have 3 studios operating at full throttle during these two days, serving the web-radio, the live broadcast, the OB van, and of course the HD video studio. All the recordings are being stored not only on the local recording drives, but right after each show, a safety backup is created onto a huge RAID storage. Because we record enormous amount of data daily, after double-checking the backup, we have to clean the record drives to have ample space for the next day.

So far, we have very minor issues, nothing showstopper, but experienced strange drop-outs on two Nuendo workstations. Fortunately the errors only occurred during rehearsals but the on-air shows went without issues. At the end of the day we’re going to do some tests to make sure that the two problematic workstations don’t have any hidden errors which could ruin tomorrow’s recordings.
