Serious Audio Video Inc. Proactive and upfront planning and coordination of the AV system is critical.A restaurant’s audiovisual system’s ability to influence the dining atmosphere is undoubtedly a powerful factor. “AV systems are no longer thought of as vanity now but as a necessity,” says Casey Johnston, founder and lead designer of
Early coordination also saves project costs. “Ahead of construction, plan the AV system around the needs of the restaurant instead of designing the AV system around the needs of a completed building,” says Rusty Howell, senior account manager at M3 Technology Group, Inc.
The first step in the AV design process is to interview the owners and operators to get a sense of what they want and what they need from a system. “Owners and managers are good at knowing what they want for their restaurant,” says Howell.
The restaurant segment and type will help shape the design of the facility’s AV system. For example, Howell says that most sports restaurateurs want every patron to be able to see four to five different TV screens at the same time.
Architects and interior designers have strategies that help restaurateurs and AV technicians achieve their end goals without compromising aesthetics. Architects and consultants can offer acoustical expertise, while interior designers can work with the team to ensure the AV system is incorporated into — and in some cases, hidden within — the interior design elements.
Developing a 3-D sketch of the AV design can make for a more collaborative and efficient planning process. “It may take us more time to complete our design, but if we can provide a three-dimensional rendering, it helps the client to better envision what the finished installation will look like,” says John Andrade, director of operations at Colorado Audio/Video. Sometimes Andrade’s team will add “cones of vision” onto the drawings to help the client also visualize the seating pattern.
Working in tandem allows the AV team and the interior designer to work toward the same goals. For example, a restaurant may choose concrete flooring for aesthetic reasons, but for acoustical reasons, cork flooring may be the better choice. Architects also should ideally dedicate space for AV equipment at the beginning of the design phase.
Sound strategies will vary by location and include a mixture of foreground and background noise. “No matter the combination of foreground and background music, both types of music need to be right,” says Howell.
Sports bars and restaurants need more foreground design with greater volumes as well as more TVs and speakers. “Some want to display all events going on at any one time,” says Andrade. “So, we need to design the sound system so that the audio is clear over the ambient noise in the facility.” Keep in mind that the numbers of TV endpoints in a sports bar could be as many as 80.
Typically, finer-dining facilities place an emphasis on backgrounding the AV system. These spaces also have few, if any, televisions or visual displays. Regardless of the facility type, the AV system should be flexible to anticipate future needs and allow for controls that can be changed, depending on the time of day and type of clientele being served.
“At lunchtime, there might be more of a background audio, and the noise needs to be nice and smooth,” Howell says. “In the evening, the foreground music may begin to emerge for family dinnertime. Even the visuals will be turned up in the evening. Then, the late-night crowd comes, and the audio will be even more foregrounded and much louder. The visuals will be set to high-energy shows, with them all on at the same time.”
AV System Design Considerations
AV system design is a critical component in creating a positive guest experience. “It’s hard to believe, but there is a difference between 50 and 52 endpoints regarding the design, acoustics and ambience in the restaurant,” says Howell.
The first decision to make is whether to go with a networked versus an analog system. “With a networked system, an owner can have a wider variety of audiovisual sources and, because this solution employs standard networking equipment for the distribution, it’s merely half the size of traditional AV racks,” says Andrade. Networked systems will use CAT5 or CAT6 shielded wiring, which takes up less space within the building and, most important, within the ceiling plenum space — a feature that is highly desirable in open-ceiling designs. Due to the fragility of CAT5 wiring, Johnston recommends adding 50 percent more wiring to allow for a double run to each endpoint.
“Analog AV equipment technically has a more stable connection,” says Howell. “Even though analog is becoming outdated, the wiring is less expensive and more durable than CAT5 and CAT6.” Analog chassis come in increments of eight endpoints, which limits the flexibility of the overall system. If the restaurant would like to add a few more endpoints, it would need to purchase an additional chassis that has a minimum of eight more endpoints.
“We have a saying in our business, which is ‘anything, anywhere, anytime,’” says Andrade. “The AV system needs to be designed to account for future expansions. With a networked system, a restaurant owner could more easily add just one or two more endpoints, while an analog system might involve the purchase of an additional chassis just to increase the overall system by one or two endpoints.”
Johnston’s company, located in New Jersey, has grown to depend on a networked, integrated AV system for restaurants. This approach tends to be more common in residential settings because it takes a more pre-programmed approach, using controls and equipment that are not quite as complex. Serious Audio Video started installing these low-tech solutions exclusively after Hurricane Sandy wiped out so many of the company’s clients’ AV systems. The more traditional type systems they had installed previously were shutting off from the storm’s power losses, and then Johnston would need to go back out to each location to reestablish each AV connection despite the fact that the systems did not suffer any other damages from the storms.
However, the residential-type systems would come back online and reestablish wireless handshakes without Johnston’s intervention when the electricity came back on. When Johnston realized how resilient these systems were, he began to install them in all of his projects.
Johnston goes on to say that they design the AV system to integrate with the lighting and the HVAC system and even to motorized drapery. So, the entire system can be turned off at the same time at the end of the day, can be controlled remotely and can even be programmed to automatically adjust throughout various dayparts, making the system incredibly easy for operators to control.
AV equipment needs to be kept clean and properly ventilated. With the trend of moving back-of-the-house functions to the front, AV systems can even be designed to stay visible to patrons. “They like seeing the lights and technology,” says Howell.
“Most often, we hang speakers from the ceiling to prevent hot spots,” says Howell. “The speakers are then supplemented with subwoofers to get an incredible sound.” Some restaurants are installing stealth speakers, which are background-only sound devices located inside the wall with a coat of drywall mud and paint over the top. Speakers can be hidden in myriad ways: behind artwork, behind acoustically transparent wall fabric, within ceiling tiles and even inside LED smart bulbs outfitted with Bluetooth.
“Hiring an acoustician gets expensive,” says Howell. Acoustic treatments and sound-masking strategies can work together to prevent reverberation. Johnston recommends hiding foam anywhere possible within the restaurant. If the restaurant has an open-ceiling design, then an acoustics challenge exists. It is ideal to add battens to soften the sound; sometimes they hang from the plenum space. Supplemental speakers could emit noise-canceling and sound-masking properties.
An acoustical engineer could be an invaluable asset to a restaurant that is particularly challenging. For example, some restaurant owners want outdoor music for their patios, but they are located in a sound-restricted zone. Acousticians can take the AV system design to a higher level for both the interior and exterior audiovisual systems.
