Work In Progress

Proposed shopping list / kit list per room

Audio

2x Headset Radio Mic 2x Handheld Radio Mic 4x 2m XLR cable (mic receiver to snake)

  • Radio Mics need to be licence free in all 3 ITU regions
  • We need to be able to change frequency to avoid interference with other users
  • Possible Open Hardware project?

2x Ambient Mic (pick up audience chatter / shout out questions) 2x Microphone stand (for ambient mics) 2x 20m XLR cable (to run from ambient mic to desk)

1x 5m 3.5mm stereo Jack to 2x 1/4" mono jacks (PC Audio to DI Box) 1x stereo DI box (2x 1/4" socket In to 2x XLR-M) active / phantom powered (PC audio) 2x 2m XLR cable (DI to snake)

1x 25m Mic 'snake' reel - 6 in 2 out

1x 8 channel mixing desk

  • Requires minimum 8 XLR input channels
  • Requires main and aux outputs (I am going to assume XLR for both of these - for this shopping list)
  • * main XLR goes to Main Camera
  • * Aux Send goes to house PA (preferably as a slide fader)

2x 5m XLR cable mixing desk to Main camera

2x 20m XLR cable mixing desk to PA (potentially via snake) 1x Balanced to unbalanced stereo balun transformer (XLR-F in to 1/4" Socket Out) 2x 2m 1/4" Mono Jack to Jack 1x 2m 1/4" Mono Jack to stereo 3.5mm jack 1x 2m 1/4" Mono Jack to RCA phono plug 1x 3.5mm Socket to 1/4" mono jack adapter
