How we work

Anyone can rent you boxes.

The difference shows up on the day — whether the rig was designed for your room, whether the tech has hung one there before, and whether the number you were quoted is the number you pay.

01

The inventory is ours

Arrays, subs, consoles, and wireless live in our Santa Ana warehouse. Nothing gets sub-rented at the last minute from whoever had it free, and nothing arrives that our techs haven’t worked on before.

02

Our crews, not a labor call

The engineers and system techs on your show work here. They’ve hung rigs in these venues, worked under touring engineers, and know where the low end goes strange in that room.

03

Quoted line by line

No “full production package” with a single number at the bottom. You get a written scope you can compare against anyone else’s, and anything beyond it gets priced before we load the truck.

Selected work

Fifty years of shows is fifty years of problems already solved.

Main stage line arrays and side hangs at Glen Helen Amphitheater during a metal set

Amphitheater

Jinjer — Glen Helen Amphitheater

The roof at Glen Helen ends a long way before the audience does. Main hangs, side hangs, and outfills built to carry a metal set past the covered seats and across open lawn without the low end folding up at the back.

String lights and vendor tents along a studio backlot street at the LA Times Taste

Tasting festival

The Taste — Paramount Studios

A backlot standing set with no house system and nowhere to fly anything. Distributed zones down the facades held levels even from the entry banner to the far end of the street, with nothing in frame that didn’t belong there.

Competition site and spectator crowd on the sand at the US Open of Surfing, Huntington Beach

Action sports

US Open of Surfing — Huntington Beach

The site starts at the pier and keeps going down the sand. Announce, competitor, and spectator zones all covered, with heats called on conditions instead of a run sheet — so the system stays up from first light to last call.
