Proposed shopping list / kit list per room
Audio
2x Headset Radio Mic 2x Handheld Radio Mic 2x Mic Stands (Good for getting people to queue up to ask questions - use with handheld mics) 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
