Critical AV Engineering Checklist
- Dedicated Board Feed: Interpreter consoles must receive an uncompressed line-level AUX feed from the mixing board. Never use ambient room microphones.
- ISO 20109 Limiting: Verify that inline peak limiters are active on all console monitor outputs to cap transient spikes at 85 dBA.
- Relay Aux Bus Patching: Confirm that Channel 02 (Spanish Master Pivot) is patched to the AUX IN port on Console 04 (Arabic Booth).
- Transmitter Positioning: Position UHF/IR transmitter radiators with unobstructed line-of-sight to delegate seating areas.
