Auditorium / cultural hall
scope outline.
Front-of-house line array, stage lighting fabric, broadcast-grade AV, acoustic envelope and assistive-listening loop. Ceremonial-grade calibration.
In scope
Line-array loudspeaker design sized to seat geometry • Stage lighting fabric (DMX with manual fallback) • Broadcast AV with SDI / NDI tally • Assistive-listening loop per occupancy • Recording bus on independent UPS
Out of scope
Acoustic treatment construction (separate civil + acoustic scope) • Seating supply • Stage furnishing and curtains beyond AV-relevant items
· Documents required
Materials the consultant needs before specification starts.
Architect's acoustic envelope drawings
Seat plan with section AA / BB sightlines
Ceremonial use brief (event types, occupancy peaks)
Broadcast intent (live / record / hybrid)
· Site survey
Pre-design walk-through verifications.
Acoustic measurement at the as-built state (RT60, reverberation curve)
Sightline survey from worst-case seats
Stage power audit (load, isolation, UPS)
· Deployment checklist
Engineering items every install of this discipline carries.
Line array sized for the actual seat geometry, not the catalogue
RT60 ≤ 1.5 s with audience present for the room class
Stage lighting on DMX with manual fallback
Recording bus on independent UPS — survives stage power-cycles
Assistive-listening loop per accessibility requirement
· Coordination with other trades
Works owed to / from other disciplines.
Civil / acoustic: treatment surfaces against the speaker placement
Fire: BGM override on the fire-alarm general signal
Networking: AV-over-IP VLAN + PTP timing
Power: dedicated UPS rails for control, recording and house mixers
· Commissioning
Measurable artefacts produced at handover.
SPL measurement at every section's worst-case seat
STI measurement under design-occupancy conditions
Stage lighting cue rehearsal
Recording bus power-cycle survival test
Assistive-listening loop calibration
· Handover
What the building team takes ownership of.
Measured-performance commissioning report
DSP and matrix configuration baseline
Stage lighting cue files
Operator training and rehearsal log
· Risk register starter
Risks worth tracking from day zero.
Audience occupancy changing room acoustic response from design
Stage power cycling damaging the recording bus
Brand-firmware refresh breaking the calibration baseline
· Exclusions and assumptions
What is not in scope; what we assume to be true.
Assumes acoustic treatment delivered as a separate civil scope
Excludes broadcast licensing and rights management
