01Overview

Start with the show formats and the venue.

A speech, a musical performance and a live camera relay place different demands on the same stage. We map the sources, audience areas, operator positions and guest connections before selecting the sound, video and lighting systems.

Sound coverage follows the audience layout and acoustic conditions. Screen size follows sightlines and content. Lighting follows performer positions and camera needs. The front-of-house position, or FOH, needs usable monitoring and clearly labelled routes to the stage.

Reference configurations · project selection and testing required. The examples below describe intended functions and planning quantities. They are starting points for design, not fixed packages or completed installations. Loudspeaker counts do not establish audience capacity.

The scope covers permanent venue systems and their agreed interfaces. Event organisation, equipment hire and provision of a show or broadcast crew require a separate agreement. Structural and electrical design responsibilities are confirmed with the venue’s appointed specialists.

Workflow, boundaries and intended result

Composition

Eight wired microphones, two DI channels and two complete wireless channels occupy twelve mixer inputs. A passive stage–FOH multicore provides twelve sends and four returns. One digital mixer feeds two powered subwoofers, two powered tops and two powered stage monitors. Four profile fixtures include selected optics and mounting accessories. One lighting console, an isolated four-output DMX splitter and terminated branches complete the lighting path. The infrastructure allowance covers labelled connections, equipment supports, power and protected cable routes.

Boundaries

The base system has no camera relay, recording or streaming. The optional presentation addition comprises one content laptop, an HDMI switcher with stereo audio extraction, a stereo audio interface and one LED surface with its processor. It uses two further mixer inputs and needs its own display power and support allowance. It does not add cameras or recording. PA and fixture quantities remain subject to coverage and photometric design.

Intended result

The technician can balance stage sources, give performers two independent monitor mixes and recall the agreed basic lighting looks.

Workflow, boundaries and intended result

Composition

Twenty-four stage source channels feed a matched stagebox and digital console. The house mix feeds a designed PA system; four further mixes feed four powered stage monitors. Stereo content playback uses two additional input channels. A separate stereo programme mix reaches the video switcher through an isolated level-matching interface. Two indoor PTZ cameras and one converted HDMI content source feed an eight-input HD SDI switcher. A direct SDI programme output feeds one LED processor and surface. A separate SDI multiview output feeds an operator monitor. One recording drive, one control workstation and one camera controller support operation. Eight profile fixtures, a lighting console and an isolated eight-output DMX splitter provide the baseline light. A local control network connects the video devices; the customer's internet service and streaming account complete the external delivery path.

Boundaries

The baseline records the switched programme. Separate camera recordings require an agreed recording mode and tested drive capacity. UHD production, automatic camera tracking, effects lighting and an independent clean screen programme require additional design. The base LED and stream share the switched picture; graphics intended only for the stream need a revised output workflow. Live relay delay and synchronisation are measured on the actual camera-to-screen chain.

Intended result

Operators can select cameras and content, monitor the sources, check the programme recording and run sound and lighting through an agreed event sequence.

One outdoor LED surface receives the programme through its processor. The control position includes source monitoring, programme recording and the selected streaming connection. Stage and FOH each have a labelled patch point and a managed network switch. Two fibre trunks provide an active route and a separately routed spare where the site permits. Selected transceivers carry network audio and control; four dedicated optical SDI links carry the two cameras, guest video and programme return. These are distinct transports with their own endpoints. Eight front-light fixtures and four wash fixtures use two DMX universes from a network lighting node. Shared infrastructure includes protected electronics, distribution of power, cable protection, supports and environmental monitoring.

Boundaries

Guest equipment must match the agreed interface sheet. The house baseline accepts a stereo guest audio programme and one HD SDI video feed; additional stems or UHD need a revised patch and equipment schedule. A spare fibre route enables a documented manual recovery procedure. It does not remove shared equipment failures or provide seamless switching. Every exposed component, connection and support must suit the installation conditions. A cover alone does not make indoor equipment suitable for outdoor use.

Intended result

House and visiting technicians can connect approved sources, identify responsibility for each subsystem and follow a tested recovery and shutdown procedure.

Common mistakes

And how the design process prevents them.

  1. M01

    Selecting PA by seat count alone

    Model the actual audience areas and verify coverage on site.

  2. M02

    Using a cable adapter as audio level matching

    Specify isolation, wiring, input mode and headroom; test peaks and noise.

  3. M03

    Treating LED refresh rate as camera-to-screen delay

    Measure the complete relay path with the actual camera and screen settings.

  4. M04

    Treating a fibre cable as a universal AV interface

    Specify the transport, endpoints, fibre type, optical budget and patch for each service.

  5. M05

    Treating covers or a spare route as complete protection

    Verify the environmental envelope and the precise failures the recovery route addresses.

12Inputs and FAQ

Before we begin.

What to send us, and practical answers before the project starts.

How many people can each configuration cover?

The examples do not have a guaranteed audience capacity. We select loudspeaker positions and quantities against the actual venue, acoustic conditions and agreed level targets.

Does the small-stage option include an LED screen?

EV-01 includes sound and basic light. A presentation LED path can be added with its source, processing, audio connection, power and support requirements. Cameras and recording belong to a different scope.

Can we use the LED for live camera close-ups?

EV-02 and EV-03 include a direct live camera path. We agree and measure the total camera-to-screen delay and synchronisation under the intended operating settings.

Is the video system 4K?

These reference production chains use HD SDI. A higher-resolution LED canvas can display that programme, but it does not make the source UHD. UHD requires a compatible chain throughout.

Can a visiting production team connect its own equipment?

EV-03 defines guest audio, video and lighting handover points. The visiting team provides its interface and rider information in advance so formats, levels, control ownership and changeover can be checked.

Does outdoor equipment work in any weather?

Each project has an operating envelope based on the selected equipment, connections, supports and site conditions. Heat, rain, wind and condensation require an agreed monitoring and shutdown procedure.

Do you provide event hire or the broadcast crew?

This solution covers venue engineering, integration and training for the supplied system. Hire, event organisation and operating crew are separate services and are included only when explicitly agreed.

Can we record each camera separately?

The baseline delivers a programme recording. Separate-source recording can be specified after confirming the switcher mode, audio mapping, recording duration and tested drive throughput and capacity.
