Gala for the Olympics

Today we have a big gala, which is a live broadcast event for us. As we’re getting closer to the Rio Olympic Games, these big events start to pop up everywhere. This one is going to be the official oath taking ceremony.

The show

The easiest and most obvious thing is that we’re going to have two speakers on stage whose job is to announce the ceremony, ask the celebrities to come to stage to speak, and announce the band who will perform a few songs. From this perspective it seems quite simple.

We’re going to have 5 band during the show with different needs.

Probably the flow will be something like this:

  • speeches
  • first band
  • introduction of the celebrities
  • second band
  • speeches
  • third band
  • politicians speeches
  • fourth band
  • short film about the upcoming olympics
  • fifth band
  • end

Let’s see this whole thing from a technical perspective. The live sound part of the show is given, I won’t go into detail with that. For us, the interesting thing is the broadcast part.

Technical background

The whole show will be mixed in Pro Tools HDX2 live with an S6. The basic template comprise of 128 inputs, all mixed down to final stereo which must be compliant to EBU R128 loudness standard. The OB truck receives our stereo mix and sync it with picture.

Sounds simple enough. I’ve got a well worked out template, so in reality it won’t be so complicated. Every band will have its own audio group and VCA master. So I have the ability to process them differently through their own audio group, but at the end I can easily have control over them the VCA masters. This is important because with this method I only have 8-10 faders at the end, which is much more easy to operate than to have 24 or more different types.

So my final MasterMix Layout looks like this:

  • Band 1
  • Band 2
  • Band 3
  • Band 4
  • Band 5
  • Speeches
  • Atmo
  • FX
  • Sum
  • Master

The combination of VCA spill and Layouts will give me the flexibility to reach anything in a second if I need to. For safety I have one Layout for each band, one for the Atmospheres and speeches and one MasterMix which shows me all the VCAs and other necessary groups and the individual mics for the announcers. The Sum group is there for various reasons. One is being a great place for overall level adjustment, the second is to have an easy control point during the live broadcast. Because all the band groups will go through the Sum, but none of the audience mics or announce mics. With this, I can easily level or remove all the performers from the broadcast while still have the announcers and the audience.

Of course, under the hood there’s many more things going on, but here’s a very simplified pic of the routing:

How it all goes

We have one full day for doing all the technical preparations, soundchecks and at the end of the day we have a full rehearsal. The next morning we have a short rehearsal, a final check and then we go live with the show.

While I record everything into Pro Tools, along with the audio the automation will be recorded too, so after the show I’ll have a complete mix with all my moves in the session. So if I need to correct something, it only takes a few seconds to make some adjustment. While our rigs are very stable, we still use multiple backups. One full backup is a Nuendo 5, the other is JoeCo Madi recorder. All running parallel to Pro Tools.

S6 during the rehearsal

Plugins used in the session:

  • Avid HEAT
  • Brainworx BX console
  • McDSP AE400
  • Maag EQ4
  • Softube TLA 100A
  • Brainworx Millenia TCL-2
  • Brainworx bx digital V3
  • Avid ProLimiter
  • Exponential Audio Phoenixverb
  • Exponential Audio R2

At the end of the first day, I can tell you that all the rehearsals went fine, I’ve got everything as it should be. Double-checked all my routings to make sure I won’t fall into my own trap. The fun starts tomorrow.
