Event production · Sound engineering · R&D · Software

Large events, engineered to sound right.

Ehnos Alpha designs and delivers production for stadiums, arenas and outdoor shows: sound systems, rigging, staging, lighting and video, planned as one show. We also build the software and products behind it.

01 · Design

Every seat is modelled before a single box is flown.

3D coverage prediction, array design and delay zones, planned for the room you're actually in.

02 · Rig

Arrays, truss and video, flown as one plan.

Rigging, networks and power drawn up together, so load-in day goes the way the drawings say.

03 · Mix

At front of house, the system meets the room.

Measured, aligned and tuned on site until the back row hears what the front row hears.

04 · Show

Then the room fills up.

Stadiums, arenas and outdoor shows, run on the day by the team that designed them.

Services

Everything a large event needs, under one roof.

We plan and run production for large events end to end, with sound engineering at the core. What we learn on stadium and arena shows feeds straight into the products and software we build.

Process

From brief to show day, or production line.

Event or product, every project runs the same signal path. Each stage ends with something you can see, hear or measure before we move on.

IN

Brief

Venue or product, audience, targets and budget.

02

Design

Prediction models, production plans, acoustic architecture.

03

Build

Load-in, rigging and networks on site, or working prototypes.

04

Tune

Measurement, alignment and DSP voicing to target.

OUT

Deliver

Show-ready production, or a product handed to manufacturing.
