Since 1974 Central Marketing Has Specialized in Representation of Pro-AV Presentation Products and Total Room Solutions What our Manufacturers can Expect Central Marketing consistently strives to meet the challenges set before us. We give the time and mind share that the products deserve, and a well tuned and knowledgeable approach to our sales efforts. We want a seamless presentation to the dealers that is backed by the training and experiences of the product line. We will only keep 10 or less core lines at any given time and carry products that complement each other and never compete as we always take a synergistic approach with the dealers.
