Celebrations and special events. Concerts in the park and driveway jams. Coffee houses and dance clubs. Wherever people gather to enjoy the soundtrack of life, we’re there.
Audio is our life. Since our humble beginnings in 1968 in a small garage in Costa Mesa, California, we’ve always set our sights on empowering performers and entertainment providers with exceptional products and unparalleled support, giving them the confidence to deliver memorable experiences for their audiences. Today, QSC is a leading manufacturer and global innovator with R&D, manufacturing, sales, marketing,
support and operations teams across multiple continents — light years ahead of that startup company selling hand-built power amplifiers assembled on wood and steel benches one-by-one from the back of a van. But no matter our size or scale, we remain grounded to our commitment to amplify life through sound.
To bring joy to people everywhere through the art and science of live performance.
We are dedicated to empowering people with the confidence to create impactful and memorable experiences for their audiences
with our innovative, high-performance, easy-to- use audio solutions and industry-best training and support.
Our values are the bedrock of our brand and guide us in our thinking and in our actions
Quality is essential in everything we make and everything we do. Consistent and pervasive quality sets us apart and increases our value to others. Constantly striving to improve our quality not only builds our business but helps us grow as individuals. Excellence is a sign of respect for our customers, business partners and ourselves.
Service is about meeting the real needs of our customers and one another. Being of service sets us apart and provides value to others. Anticipate the needs of others and help them to be successful. Let care for others guide your decisions and efforts.
Commitment is standing behind our word. Act with integrity, based on the long-term best interest of all parties, building trust. Do the right thing simply because it is the right thing to do. Go the distance to ensure that a promise made or implied is a promise kept.
We are better when we work together. Harness the power in individuals through effective teamwork within QSC, and in all our business relationships.
Respect, Dignity and Opportunity
We honor and respect the dignity of all people and celebrate the uniqueness of each individual. Our culture empowers everyone to bring their full, authentic selves to work and provides equal opportunities for growth and advancement based on skill, competence and potential. At QSC, it’s not about what makes you different. It’s about the difference that you, uniquely, make.
Work Hard / Enjoy Life
Joy and hard work go hand in hand. Nothing of lasting merit can be achieved without hard work but hard work cannot be sustained without a balanced life. Our goals and standards make hard work essential, but we make time to take care of ourselves – body, mind and spirit – making work enjoyable and fun in the process.

The son of a Marine aviator, Pat Quilter’s interest in physics and electronics can be traced back to his high school days. “My high school physics course taught me everything I needed to know to get started in electronics, and laid a foundation that allowed me to begin building my first crude circuits in college,” says Pat. After flunking out of college due to the distraction of “hands on” learning of electronics, Pat moved to Southern California and began building guitar amplifiers to meet the needs of local musicians and artists. As the guitar amplifier business evolved into a professional audio amplifier manufacturing organization, Pat focused on product development efforts that included the awarding of several design patents and innovative products that revolutionized the world of professional audio production. “Looking back at it all, I was pretty idealistic. I just wanted a cool little company that built nice stuff, didn’t burn anybody, and let me make a decent living,” says Pat. ”Thanks to the efforts of many others who shared in the vision, we greatly exceeded that goal over the years.” In 2011, Pat returned to his passion of designing and building guitar amplifiers, and founded Quilter Labs where he designs and builds amps for some of today’s biggest artists in music. www.quilterlabs.com

A broken British motorcycle turned into a defining moment for Barry Andrews. He walked into Quilter Sound Things seeking a ride home and ended up with a lifetime career. At 18, Barry started building guitar amp cabinets. Some years later, he talked Pat into to letting him try to manage the company. The early days at Quilter Sound were an incredibly tough but valuable real world school. Along with Pat and John, he led the company as it evolved from a three person guitar amp shop to QSC, a world leader in professional audio sound reinforcement. Barry went on to become the CEO of QSC Audio for over 30 years- driving business strategy, product strategy, sales and marketing activities. No longer involved in day-to-day management Barry is not retired and remains highly active. As a board member of QSC he focuses on long term strategic planning and the coaching and mentoring of QSC executives and managers. Outside of QSC Barry seeks to help entrepreneurs starting their own businesses, having made a promise himself to do so as a young man. He writes and produces documentaries focused on planetary health and Barry and his family have an entertainment production company that develops both film and television projects. He travels extensively having been to all seven continents and over 50 countries to date. He loves overlanding in remote parts of the U.S., designing and building expedition vehicles, fly fishing, cooking, photography and after a 40-year gap, riding motorcycles.

John joined a fledgling QSC while still in high school, working part-time in the woodshop assembling cabinets and stuffing circuit boards as needed. While in college, his role within the company expanded and he soon took on running the front office; still with an eye on a career in real estate development. "At the time, I viewed QSC merely as a stop along the way and I was intent on moving on once I graduated,” says John. “I didn’t expect this to be a career.” Remaining with QSC after graduating from University of Southern California however, was a major cause of consternation with the Andrews family. John’s brother Barry recalls, “My father was furious at me. I remember him yelling, ‘We never thought you’d amount to much, but we had expectations for John!’" John’s full-time, early years entailed lots of on-the-job training particularly in the areas of manufacturing and operations which was a company need and fortunately of interest to him. A particular point of pride for John was his leadership role in the creation of the company’s “build to order” manufacturing capability which had a tremendous impact on the growth of QSC. Today, John still comes into the office but most of the day-to-day business operations are left to the team of talented individuals he helped assemble over the years. When he is not in the office, he is eager to share his business knowledge with his children who in turn have shown their own entrepreneurial spirit.
