National Audio Company has always been proud to say our cassettes are made in the USA. Since 1969 National Audio has assembled and loaded custom lengths of cassette tapes using domestic and imported parts. We have been a reliable service for library and education systems, 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. Some of the larger companies that left the audio tape duplication business are now regular customers of National Audio Company.
We’ve recently expanded our capabilities to include the manufacturing of magnetic tape right here at our facility in Springfield, Missouri, USA. As the past sources for the tape we used are no longer available, we’ve acquired the necessary equipment, restored and upgraded it, mastered its use, and dedicated an entire floor of our historic building to produce top-quality magnetic tape. Our engineers have perfected the formulas for three types of tape in our lab, all of which are now in production.
In addition to manufacturing the tapes, we offer a wide range of packaging options: we imprint and label the cassettes, provide custom printed inserts and materials—including Braille labels—and provide boxing, overwrapping, and mailing services. Over the years we have produced custom private-label packaged cassettes for several major brands.
The three tape types we currently offer are:
FerroMaster C256TM is the classic ferric cassette tape you know and love. It is refined for use in consumer cassette decks for high-quality recording and playback. No custom biasing is necessary.
FerroMaster C456TM is the highest quality ferric cassette tape available in the world today. This product has been tested in high-speed duplication equipment and delivers outstanding quality. This tape is used for the numerous duplication orders that NAC produces in-house daily. It is available on bulk pancakes for other professional duplicators. (Note: professional bias adjustment is necessary for the best results with C456.)
FerroMaster C756TM is a Cobalt oxide Type II High Bias tape for the most demanding recording applications– C756 is the gold standard in Type II performance. Cobalt oxide combines outstanding output with low distortion, providing unmatched musical clarity. This tape, now being made at NAC, delivers up to 4db more output than earlier Type II tapes without saturation or distortion.
ALL FerroMaster tapes are now made with NAC’s exclusive MAGNE-SHEENTM process for a smoother, more capable tape. Click for more information.
