The Martin Group is launching the MAC 500SP and MAC 600NT in the US market, replacing two of the products that continue to be affected by an injunction that prevents their sale.

The products are primarily used in the professional segment, including concerts and tours, as well as in film and TV studios. Martin's engineers have developed a completely new, patented color-mixing system for the MAC 600NT. Both products lie outside of the US patent, which is the basis of the litigation with Vari-Lite.

The Federal Appeals Court in Washington was expected to hear an appeal in February. Regardless of the decision, Martin can sell the new products in the US market, reducing the economic impact of a continuation of the injunction on the firm.
