NAC has always been proud to say our cassettes are made in the USA. For decades National Audio has assembled and loaded custom lengths of cassette tapes using domestic and imported parts. We have been a service for library systems and education producing books, magazines and tests on cassette. When large audio production houses and music labels stopped producing cassettes, National Audio began accumulating equipment to become the largest duplicator of music recordings on tape as well. Now, some of the larger companies that got out of the audio tape duplication business are regular customers of National Audio Company.
Recently, new capabilities have been added so the magnetic tape itself is also manufactured here in our facility in Springfield, Missouri, USA. The sources for the tape we used over the years no longer exist, so we have purchased the necessary equipment, restored it, improved it, learned to use it, and dedicated a floor of our historic building to the manufacture of the highest quality magnetic tape possible. Our engineers have refined the formulas for three tape types in our lab and they are all currently being produced.
Along with the tapes themselves, our departments also imprint and label the cassettes, and our departments produce the printing for packaging, including Braille labels and mailing services. We have made private label packaged cassettes for several major brands. Call us for more information 417-863-1925.
