Nearly 60 years of history had to start somewhere.
Your part in our history can begin today.
Before there was a PUI Audio, there was Projects Unlimited Inc. And before that, back in 1940, there was Wyse labs, leasing a small space in downtown Dayton, OH, near Wright-Patterson Air Force Base. We manufactured scale model aircraft, equipment, instruments, and more. By World War II, Wyse Laboratories expanded our operations and increased staff to 150 people. After the war, our company changed directions, entering commercial manufacturing, including developing and manufacturing the standout Wyse-Cycle, a small 4-cycle engine-powered motorbike. By 1947, Wyse Laboratories was succeeded by GADGETS, INC. and we began directing our energies towards fulfilling military spare parts requirements.
In 1951, as volumes increased and military electronics became more complex, Projects Unlimited was born. We became actively engaged in manufacturing new equipment in many fields and maintaining quality spare parts. Even then, PUI was on the cutting edge of other technologies, including introducing the world’s first digital depth sounder.
In 1972, Projects Unlimited moved into a new 28,000 square foot facility, which was soon expanded to 38,000 square feet. Our enhanced engineering capabilities allowed us to enter into producing relays, cables, harnesses, and test equipment. Work on military cables led to joint development with McDonnell Douglas’s Sparrow Missile motor fire cable for the F-4, F-15, and F-18 aircraft. Additional development work with many aerospace customers helped solidify our growing reputation as a provider of highly reliable products for aircraft and missile systems.
1972 was also the year Projects Unlimited entered the field of solid-state buzzers. Rapid growth of a product line of telephone test sets led to the introduction of a new term in the industry, the audio indicator, differentiating solid state products from older, less reliable mechanical buzzers. In 1974, we introduced the Dip Alarm® and Dip Flash®, the first “circuit board mountable“ audio devices.
Continued audio growth led to the establishment of the Audio Products Division in 1972.
In 2008, the Audio Products Division rebranded to PUI Audio– A Division of Projects Unlimited. PUI Audio continues to grow and expand the products we offer, taking on new challenges and providing industry-leading audio solutions.
Today, PUI Audio’s products are still proudly crafted to the highest possible standards. We utilize a comprehensive network of distributors and manufacturers’ representatives to extend our products, services, and solutions to customers worldwide. We’re growth-oriented, but maintain a firm grasp on our history and core values. We exceed our customers’ requirements with consistent value-added solutions at an affordable price.
But the reason we’ve become a world-class audio leader, unparalleled in global coverage, products, service, and support, is because you simply can’t get a higher quality audio device.
