The $85 million Rady Shell at Jacobs Park, the brand new outdoor home of the San Diego Symphony, is an architectural wonder on the edge of San Diego Bay and in the heart of the city’s downtown.
Designed to complement the sails of the nearby San Diego Convention Center, the concert shell is wrapped in a translucent flexible material that covers a generous 13,000-square-foot performance space for accommodating the full orchestra and guest artists.
Depending on the event, audience capacities and setups are able to vary widely, from intimate two- and four-person table seating arrangements to standing crowds of up to 10,000.
As an outdoor symphonic space, “The Shell,” as it has come to be known, has a large L-Acoustics PA system integrated into the venue as part of its infrastructure, and the immersive nature of the PA system requires powerful and sophisticated mix platforms to control it. That’s why the San Diego Symphony chose three DiGiCo consoles for the task.

A Quantum7 is installed as the front-of-house mix desk, with a DiGiCo SD10 for monitor mixing and an SD12 on hand for any auxiliary mix and processing needs. The three consoles, three SD-Racks located on stage, and a Mini-Rack in the amp room are all on a dual Optocore network, and the entire system was designed and integrated by Solotech.

“There are several reasons why we chose the DiGiCo consoles, and they are all areas that the brand excels in,” says Aaron Beck, Business Development Manager and Senior Engineer at Solotech.
“First, there’s capacity—the Quantum7 can run 200-plus inputs. Then there’s the Quantum processing power.” Becks cites features like Quantum’s Mustard Processing channel strips, Spice Rack plugin-style native FPGA processing options, and Nodal Processing all as standout features. “Plus, there’s the overall quality of the sound, which is exceptional,” he says.
The Rady Shell at Jacobs Park will see scores of visiting touring groups each year, many of whom will bring their own audio engineers and all of whom will be familiar with DiGiCo console architecture and operation. That familiarity will be important for more than just operational reasons. Jacobs Park is located within a major metropolitan area that, like many, has stringent noise regulations.
San Diego has deployed NTi Audio noise measurement devices nearby that automatically issue reports via cellular data to key elements of the city’s environmental control, as well as directly to the house engineer at Rady Shell. “The venue’s engineer can adjust the overall volume of the entire system from the FOH console when necessary to keep every show within compliance,” he says.

Joel Watts, the Symphony’s Audio Director notes that the 32-bit “Ultimate Stadius” microphone pre-amps on the SD-Racks are the next best thing to the kinds of high-end mic pre’s he’d choose in the studio for recording classical orchestras. “My background is in studio production, and we’re recording most of the performances here for later postproduction, and the DiGiCo mic pre’s sound fantastic,” he says.

Having said that, “The Shell” also sounds fantastic thanks to an immersive L-Acoustics PA system designed in Soundvision by François “Frankie” Desjardins of Solotech. Working in tandem with sound consultant Shawn Murphy, Solotech integrated the venue’s full AVL system.
“It does look as good as it sounds,” says Solotech Business Development Manager and Senior Engineer Aaron Beck. “The white exterior wrapping material is a kind of plastic cloth and the interior is covered with a white scrim material. L-Acoustics was able to provide an entire K2 system in white, as well, to match it.”
The system comprises two main arrays of 16 L-Acoustics K2 per side, flanked by two hangs of eight cardioid-configured KS28 subs per side and a center array of nine K2. Another 16 KS28, also in cardioid configuration, are located underneath the stage.

In addition, six towers comprise the surround elements of the 7.1-type system design: two side-surround towers per side (for a total of four) hold four A15 Focus speakers each, with the rearmost tower on each side also holding six Kara II with adjustable HF-steering fins. Two rear-surround towers are fitted with four Kiva II and two SB15m subs each.
The system is powered by two dozen LA12X amplified controllers, with system processing by L-Acoustics’ LA Network Manager.
While it’s designed to project the orchestra across the wide span of the open-air venue, this powerful PA system will also offer Rady Shell and the San Diego Symphony a highly flexible venue that will easily accommodate a wide range of visiting artists.

It will also give the orchestra the impact it desires when performing live scores from movies shown at the park. Beck says the immersive design of the system reflects the growing demand by touring artists for that type of sound and the L-Acoustics system at Rady Shell does just that very cost-effectively.
“One way we’re achieving that sense of immersion is by taking some of the reverb returns from the front-of-house console and sending them to the surround speakers, which really enhances the immersive effect,” he explains.
Beck also notes that the large number of subwoofers has less to do with impact than with directionality. “There are very strict noise-control measures in place here and on nearby Coronado Island, and the KS28 subs in the cardioid configuration give us tremendous ability to steer that energy where we want it to be and away from where we don’t want it.”
The same, he says, go for the K2 Panflex horizontal steering technology, which combines mechanically adjustable fins with DSP algorithms effective from 300 Hz. “It’s all about putting the sound on the seats and keeping it from escaping the venue,” Beck adds.
“K2 gives us not only excellent sound quality but also the tools we need to stay in compliance with local noise ordinances. Soundvision was incredibly helpful for that.”
Joel Watts
San Diego Symphony Audio Director Joel Watts says that this sound system is highly unique and particularly effective for amplifying a symphony orchestra in an outdoor environment. “In a space like this, where the seating goes back a full 200 feet, the only way to fill it with acoustical music, is with amplification.
But it has to be done in such a way that everyone hears only the music, never the speakers,” he explains. And it sounds marvelous.”
Watts also points out that the asymmetric configuration and precise placements of the speakers allow the orchestra to achieve full impact without exceeding the noise restrictions.
“We have full dispersion to one side of the system and virtually none to the other side, thanks to the fins on the K2,” he says. “It focuses the sound and keeps it on the seats. It never crosses the lease line.”
En plus de porter les enceintes d’ambiance, les tours sont aussi prisées par les artificiers.
The L-Acoustics system also makes the venue fully rider-ready. Finally, says Beck, K2 and the other speakers that make up the system are all remarkably robust, able to withstand the kind of weather they will face since they’re right next to the ocean.
“But the L-Acoustics speakers handle that very well. Combine that with how rider-friendly they are, and you easily see how they were the best choice for this project.”
