Case study
Milken Institute
Full technical production for the Milken Institute's Global Investors Symposium at the Four Seasons Mexico City — audio, lighting, video, streaming and infrastructure run as one system across five event spaces.
Introduction
This production was delivered as Castelein AV — the same team that now operates internationally as First Impact.
The Milken Institute's Global Investors Symposium brought international finance and investment leaders to the Four Seasons Hotel Mexico City for a high-level forum. The production had to run across five distinct spaces at once — the Plenary Hall, two breakout rooms, the foyer, and a dedicated speaker ready room — each with its own audio, video and staging requirements, coordinated as a single event rather than five separate bookings.
The brief came through a UK-based international event agency working on behalf of Milken Institute, with the Four Seasons as the venue partner. That meant coordinating technical delivery across three stakeholders — agency, client and venue — while keeping one point of accountability for everything that touched sound, light, screen or signal.
Objective
The brief called for flawless, end-to-end technical production for an international forum: audio, lighting, video, live streaming and infrastructure integrated as one system rather than handled space by space. That meant full coverage of the Plenary Hall, two breakout rooms, the foyer and the production and speaker-ready areas — with simultaneous interpretation, CCTV monitoring, image processing, dedicated power generation, ICT infrastructure, intercom, scenic elements and printed graphics all running under the same technical direction.
With international investors and speakers in the room and a live stream carrying the program beyond it, there was no room for the production itself to show — the forum had to read as one continuous, high-level event from the Plenary Hall to the breakout sessions.
Scope
What had to hold
Plenary Hall Production
Full audio, lighting, video and staging for the symposium's main stage — the technical and visual anchor for the entire forum.
Multi-Room Coordination
Two breakout rooms and the foyer equipped and run in parallel with the main hall, under one technical plan instead of separate setups.
Simultaneous Interpretation
Bosch interpretation infrastructure deployed for a genuinely international audience, integrated into the main audio system.
Live Streaming Integration
On-site production paired with a live stream so the on-site and remote audiences received the same program without a downgrade in quality.
Autonomous Power and Infrastructure
Dedicated power generation, ICT infrastructure and CCTV monitoring built in as standalone systems, not dependent on the venue's own capacity.
Speaker Ready Room and Production Office
Dedicated backstage spaces for speaker preparation and production coordination, run alongside the public-facing spaces.
Solution Implemented
How it was produced
Layered PA Across Five Spaces
Bose Showmatch and Bose L1 Pro-16 systems anchored the main hall and breakout audio, with JBL Eon One covering secondary areas, all mixed through DiGiCo and Allen & Heath consoles.
Wireless and Interpretation Layer
Shure Axient and Shure QDX wireless systems carried the speakers, with a Bosch simultaneous interpretation system and a 17-channel Clear-Com intercom keeping every department connected.
LED and Image Processing
An MRLED RVO2.9 LED screen anchored the main stage, driven through a Barco E2 processor with Resolume Arena and Apple MacBook Pro handling playback.
CCTV and Switching
Panasonic 4K cameras fed a Blackmagic ATEM switcher, with Samsung 55" and 75" 4K displays extending the program into secondary spaces.
Lighting Built for a Plenary Stage
ADJ Electrapix and Chauvet Wellfit fixtures for wash, Conic 120 profiles for key light, and Chauvet Rogue R3 Wash moving lights, all run from an ETC Hog console.
Redundant, Autonomous Power
Dedicated power generation and ICT infrastructure gave the production a self-contained backbone, independent of the venue's own systems, with redundancy built into the critical paths.

Results
What it delivered
Seamless International Forum
A high-level symposium delivered without a visible technical seam between the Plenary Hall, breakout rooms and foyer.
Continuous Operation, Five Spaces
Reliable technical operation sustained across all five event areas for the full duration of the symposium.
One Experience, On-Site and Remote
A high-impact audiovisual experience carried through equally to the live stream audience, not just the room.
One-Stop Technical Delivery
A single, centralized technical operation replaced what would otherwise have been separate suppliers per space.
Three Stakeholders, One Point of Contact
Coordination held cleanly between the UK-based agency, Milken Institute and the Four Seasons, with a single technical point of contact throughout.
Value Added
Beyond the brief
Fully Integrated Turnkey Solution
Every technical and scenic element — audio, lighting, video, streaming, staging and infrastructure — delivered under one scope, not assembled from separate vendors.
Redundancy Built Into the Infrastructure
Dedicated power generation and critical-system redundancy meant the production carried its own reliability, independent of the venue.
Flexible Across Five Spaces
The same technical plan scaled cleanly from the main plenary stage down to breakout rooms and the foyer without losing consistency.
International Stakeholder Coordination
A UK agency, a US-based institute and a Mexico City venue worked from one technical plan instead of three separate ones.
Visual Impact for an Investor Audience
LED, lighting and staging designed to match the standard an international investor audience expects from a symposium of this profile.
