Setup & Checks

Setting Up the Mixer

If everything is crap you really need to get hold of Q or ask for help at the irc channel to get the mixers back to a sane setting. Hopefully this won't be needed, because I, for one, hate the sight of blood!

Pre-day Checks

For the first talk of the day check that:

• check the main output is muted
• turn on phantom power
• check the power speakers are on and bring up the main output
• check each of the mics work
• check the levels are sane
• check the mix is getting to the camera
• check the levels of the mix at the camera are good
• turn the ambient mix up to 0, unmute it and confirm you can hear discussion in the room
  • listen to the appropriate bus on the mixer
  • listen on the stream itself

Pre-talk Checks

• check each mic is working
• confirm the levels are OK
• confirm the mix is getting to the camera
• check the batteries are not running low
  • low battery will show a red light on the speaker mic
• run a sound check with the speaker

Post-talk Checks

• Turn down the main mix
• Mute all channels
• Check all mics are turned off (including the speaker mics)
