A/V booth and commissioning
| Team | Keyman 🔑 | Crew |
|---|---|---|
| A/V Booth | Micah Phillips; Mint Phillips |
Audio overseer: Alex Li.
Purpose Thank you for looking after the heart of the system! Your team sets up and connects the AHEC-2 (audio headend) and the media PCs at the A/V booth, connects the venue wireless microphones and projector link, and then commissions the system with Alex.
Assignment scope
Alex arranges the two media PCs, and your team runs their audio lines from AIF-1 and AIF-2 to AMC-3 (audio multicore) inputs 7 and 8. Audio Cabling brings all other cables to the booth. Power brings the booth supply.
⚠️ Booth safety
• Please keep all equipment switched off while connecting.
• Switch on only after the Power team hands over the supply, and test at low level first.
• Lift the AHEC-2/1 (audio headend rack, 25 kg) with a helper.
• Keep the operator aisle clear and label every cable at both ends.
