Halloween Horror Nights (HHN)
Every fall since 2005, we have been an integral part of HHN. Our company is typically responsible for audio content and system design, show control design and implementation, video system programming, and installation and operation of all mazes and the backlot Terror Tram. In any given year, we run over 120,000 feet of cable, install more than 500 speakers, and program and operate six or more show control systems over the course of this project.
Universal Studios Hollywood
We here at Diablo Sound have been working with Universal Studios for more than a decade on projects such as Halloween Horror Nights, Grinchmas, Universal’s House of Horrors, the Van Helsing attraction, and The Mummy Returns maze. Drew Dalzell, our President, has personally been involved with Halloween Horror Nights for over two decades.
VHE | Marvel Avengers S.T.A.T.I.O.N.
Since 2016, Diablo has worked with Victory Hill Exhibitions to design the audio system, program audio and show control, and oversee installation of Marvel Avenger’s S.T.A.T.I.O.N. exhibitions in Las Vegas, Paris, Singapore and Taipei.
To get a sense of the scope of these projects, watch the 30-second sizzle reel for the Las Vegas Marvel Avengers S.T.A.T.I.O.N.
Feld Entertainment | Trolls the Experience
The Diablo Sound team enjoyed executing the audio and control systems design on Dreamworks’ Trolls The Experience, an immersive, fun-filled, 12,000-square-foot adventure that transports guests into the color-rich and musical world of Dreamworks’ Trolls. This one-of-a-kind, fantastical experience opened in the heart of New York City on Thursday, November 15, 2018, located at 218 West 57th Street (between Broadway and 7th Avenue).


VHE | Transformers Autobots Alliance
Working in conjunction with Victory Hill Exhibitions (VHE), we provided the sound design and integration as well as the video programming and show control design for Transformers Autobots Alliance. Cityneon Holdings Limited – and its wholly owned subsidiary, VHE – officially opened the doors on Hasbro’s Transformers Autobots Alliance interactive exhibition on January 11, 2018 in China. We also executed its move to Jeju, South Korea.
This collaboration puts exhibit-goers at the center of an interactive Transformers experience; an awe-inspiring, walk-through attraction featuring familiar characters from the iconic franchise such as Optimus Prime, Bumblebee, and Windblade.
Warner Bros. | Horror Made Here
In 2018, for their 2nd year, Warner Bros. Studio Tour Hollywood dared you to enter their iconic backlot for Horror Made Here, an incredible Halloween party where evil clowns, demon nuns, super villains, possessed dolls and the devil himself came to life. The crowds enjoyed nightmares from IT, The Conjuring, Freddy vs. Jason, The Exorcist, and from the DC Universe, Batman: Arkham Asylum. The Diablo Sound team created the sound, video, and control systems design, as well as performed the installation.


Cross Roads Escape Games | Psych Ward
Our team put in their collective expertise and skills to make Psych Ward, the latest living puzzle at Cross Roads Escape Games, an exciting journey into madness. As Cross Roads states: “This is not your average escape room. The Psych Ward is an interactive game of deduction, trust, and betrayal with escape room, board game, and immersive theatre elements.”
Led by our Lead Programmer, Fernando Vasquez, and our Senior Project Manager, Noelle Hoffman, our team developed and executed all of the show control, network, video, sound, and lighting system designs. Show Control orchestrated the precise and critical communication between Audio and Lighting systems, 8 interactive video displays, 8 Raspberry PI computers, 4 Barcode Scanners, 2 Intel NUC Computers, and countless Arduino micro-controllers. Our efforts powered dozens of puzzles, adding the ability for bypassing, repeating, and looping back to puzzles if required. All aspects of the escape room were automated, reporting real time status updates to a touch-screen interface operated by a single game master.
Nickelodeon | Nick Hotel & Nick Cruises
Nick Hotel
From 2007 until the hotel recently closed, our company worked with Nickelodeon Family Suites in Orlando, Florida, on a number of projects. Our President Drew Dalzell acted as the show control programmer in Studio Nick for Nick Live Family Style Goes Wild!, SpongeBob’s Bikini Bottom Bash, Nickelodeon’s Slime Party, SpongeBob’s Christmas Spectacular, The 12 Days of Nickmas, and Double Dare Live! He also provided guidance for show control, audio, and video systems at the resort. The team provided system design, project oversight, and systems programming for a new poolside audio system and programmed Let It Snow on the Oasis Pooldeck. We also designed and installed a new audio control system for the NickToons Restaurant, a new video playback system for Studio Nick, and updated the existing show control and audio playback systems.
Nick Cruises
Our company has worked as a liaison between Nickelodeon and onboard technical cruise staff to bring Nickelodeon’s quality family productions to the high seas since Nick’s inaugural cruise in the summer of 2008. As Nickelodeon’s Technical Director, our President Drew Dalzell oversaw the implementation of over 27 new shows in seven+ venues during each week-long cruise on the Freedom of the Seas (Caribbean) and Mariner of the Seas (Mexican Riviera). When Nickelodeon moved on to a new relationship with Norwegian Cruise Lines, he continued on in his role as Technical Director for Nick @ Sea. Our staff worked with Nick and Norwegian staff to implement Slime Time Live on The Norwegian Jewel and the Norwegian Epic, and Drew again took on the role of Technical Director for both Nickelodeon All-Access Cruises in 2011.
Utopia Entertainment
We here at Diablo Sound have partnered with Utopia Entertainment for large scale installations on a number of projects. From 2007-2009, 2012, and 2015 to the present, we worked with Utopia in Beverly Hills to bring the festive sounds of the holidays to the Rodeo Drive area with their BOLD Holidays program. Working overnight to avoid disrupting this busy neighborhood, we attached speakers to trees lining miles of streets and coordinated audio content delivery. These speakers were coordinated wirelessly and maintained and monitored by our team throughout the project’s run. In 2017, the season was extended to provide the area with music from July through the holidays.
In 2011 Utopia brought Diablo Sound in for control programming and audio work at the San Diego Zoo for Camp Critters, and in 2012 we worked on the zoo show The Legend of Dragon Mountain: Heibei Chinese Acrobats.
Griffith Observatory
Our company has an ongoing relationship with the world-renowned Griffith Observatory in Los Angeles, CA. We programmed LCS for all recent shows in the Samuel Oschin Planetarium: Water is Life, Centered in the Universe, First Light: The Telescope Changed Everything, Light of the Valkyries, and Time’s Up.
Additionally, for First Light, we coordinated sound effects production and music composition, and for Light of the Valkyries and Time’s Up we provided sound effects design and music mixing.
