AVL systems: audio, visual, and lighting for live events
AVL covers the technical systems an audience experiences directly: sound reinforcement designed for the room, video and LED display, lighting design and rigging, show control and playback, crew communications, and the power and redundancy planning that keeps all of it running live.
AVL is where an event is judged fastest. An audience will forgive a late start; it will not forgive not being able to hear the speaker, or a screen that goes black during the moment the whole evening was built around.
ONE PASS designs AVL against the actual room and the actual run of show, not against an equipment list. Coverage is modelled for where people will really be sitting or standing; lighting is designed for what the cameras need as well as what the room needs; and the show is built with a defined redundancy position on the elements that cannot be allowed to fail.
On projects where ONE PASS also holds event management, AVL planning starts at the same time as the programme, which is the point at which content deadlines, rehearsal time, and stage design can still influence one another.

Who this
is for.
Where a single unrecoverable moment — an announcement, a reveal, an anthem — carries the whole evening.
Multi-speaker programmes where slide handover, playback, and stage timing have to be seamless across a long day.
Sites with no built-in AV infrastructure, where coverage, power, and weather all have to be solved rather than assumed.
Where lighting and audio have to satisfy the camera and the broadcast feed as well as the room.
How we
deliver it.

Questions about
AVL Systems.
Can ONE PASS work alongside an AV supplier we already use?
Yes. AVL can be delivered as a standalone scope or as technical coordination over a supplier the client has already appointed, with ONE PASS holding the design intent and the show-day accountability.
Does ONE PASS handle broadcast and streaming?
ONE PASS designs and operates the in-room AVL and coordinates with the broadcast or streaming crew so lighting levels, audio feeds, and camera positions work for both the room and the output. The broadcast operation itself is normally a specialist partner's scope.
When do you need our screen content?
Content deadlines are set backwards from rehearsal, not from the event date. Content that arrives after the technical run has not been tested on the actual system, which is where most show-day AV failures originate.
What happens if a critical system fails during the event?
Redundancy is agreed in planning for the paths that cannot be allowed to fail, and the crew rehearses the switch. What is protected and what is accepted as a single point of failure is a documented decision, not an assumption.
Is equipment owned or rented?
The specification is built around what the event needs. Sourcing is handled by ONE PASS as part of the scope, so the client deals with one accountable team rather than managing a rental relationship.
