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 across both recorded and audience-led formats.
Following an initial site visit, the priority is to create modular workflows that allow the room to remain multipurpose, adapt to each requirement and maintain a high aesthetic standard.
Audio, lighting and control are coordinated around the supplied ground-floor plan and the venue’s hospitality layout. The brief establishes a distributed audio approach so spoken word travels naturally and every audience member can listen comfortably.
ConfidentialThis proposal and the information contained within it are intended solely for the client. They must not be shared with third parties or competitors, or used for publication, without prior written approval.
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+ Cat 6 camera points provide clear stage 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
We will set each support zone from the measured acoustic path difference, using approximately 2.9 ms per metre as the starting point. Local coverage will arrive just after the preferred stage source so speech remains anchored to the stage.
We will address the rear-wall points, seating-truss infill and bar coverage independently. Each zone will have its own level, delay and EQ so the system supports the nearest seats without pulling the sound image across the room.
We will reduce phasing issues through controlled aiming and minimal overlap. At commissioning we will confirm polarity, align arrivals through the speech band and trim delay, level and EQ until adjacent zones combine evenly.
We will measure every overlap area, then walk the complete audience space to check level, tone and localisation. The approved DSP settings will be saved as protected room presets.
