GA-00 · Ground Floor AV
Client proposal · GA-00 · Concept issue 01
This proposal sets out a discreet, distributed system for intimate events, recorded conversations and live production. Audio, lighting and control are coordinated around the supplied ground-floor plan and the venue’s hospitality layout.
01 · Ground-floor install
Furniture as placeholder as per CAD drawing, AV positions, LX and production fittings as per site visit.
Design intent is based on the supplied ground-floor CAD. AV positions, fixing points, cable routes, power, acoustic performance and structural loads remain subject to site verification and detailed design.
02 · AV line plan
A single line drawing showing the proposed audio, lighting, power, staging and production-control positions against the extracted ground-floor geometry.
The architectural base is simplified so proposed production positions, references and signal direction remain clear. Final positions remain subject to measured site coordination and commissioning.
03 · Production feature set
04 · Staging & production
The proposed infrastructure supports controlled recording when the room is closed and networked multi-camera production when it remains open for an audience.
A full-height black curtain behind the stage creates a controlled, neutral backdrop for conversation, presentation and camera work. It can be drawn for production and parked clear for hospitality use.
A sliding faux-wall assembly could conceal a shallow scenic bay for screens, set pieces or a green screen. It is excluded from the base AV scope and requires a separate design, feasibility and cost exercise.
Closed-room recording
Hard-wired SDI camera feeds and programme audio route to the recorder/server for reliable programme and isolated recording.
Open-room production
PoE-connected cameras provide clear sightlines without adding floor positions. Feeds return over the managed AV network for switching, recording and streaming.
05 · AV & technical specification
The core system is housed in a roll-out flight case so production equipment can be secured, serviced and removed between events. The 18U layout is an initial space allocation; final rack units and ventilation follow equipment selection.
Indicative capacity only. Final RU allocation follows product selection, cable review, power loading and thermal assessment.
Rack-mounted digital mixer, dedicated iPad control, digital stage box, scene recall and multitrack-capable audio transport.
Rack amplification with loudspeaker processing, limiters, zoning, alignment delay and commissioning presets.
Rack-mounted audio and video receivers with antenna distribution, coordinated RF plan and labelled patching.
Recorder/server, SDI patching, programme monitoring and NDI integration for recording, switching and streaming.
Managed PoE switching, segregated AV network, dedicated control Wi-Fi and wireless DMX gateway.
System flow
Concept signal paths · detailed schematics to followSpeaker timing
Each delayed zone is held back so its sound reaches the audience just after the preferred source. The DSP delay is based on the difference in acoustic path length: approximately 2.94 ms per metre. This keeps the stage or primary zone perceptually in front while the nearer loudspeaker provides local level.
The two rear-wall stage points, the seating-truss infill and the bar pair are independently addressable. The truss infill runs lower in level and receives its own delay so it supports the near chairs without pulling the sound image away from the stage.
Commission with a measurement microphone at the overlap zones. Match polarity first, then time-align arrivals, compare phase through the speech band and trim level so adjacent zones combine smoothly rather than compete.
Limit unnecessary overlap through aiming and level control, use consistent processing paths, apply high-pass filtering to the infill where appropriate, and use all-pass correction only when measurements show a phase-response mismatch. Confirm the result while walking every seating area.
