MACKENZIE LABORATORIES

Mackenzie was founded in 1954 to produce repetitive audio systems based on our patented endless-loop, power-drive tape magazine. Early successes in a wide variety of applications led to the development of special products to fit specific industry needs. Mackenzie pioneered the automatic flight announcement system used in airports, as well as the first practical Digital Feedback Eliminator and Overhead Page Management System... At Mackenzie, knowledge is power. We are committed to meeting the needs of the marketplace.
