Challenger Mk3

The CHALLENGER turntable weighs in at 23kg, to offer you our statement in entry level high mass turntable. With this latest CHALLENGER design, we bring together one of the most sophisticated external drive and power supply systems, with a massive high mass 50mm thick platter, supported by a solid 40mm thick chassis. The new CHALLENGERMK3 is a consequent improvement of the former design. It‘s combined with the award-winning performance, elegance, convenience and comfort that have made our mass turntable Series so successful all over the world. At the new CHALLENGER MK3 the massive Aluminum platter is a perfect fit for the Tidorfolon bearing spinning the platter. Up to 3 Arms can be placed around the plinth and are easy adjustable.

Our digital motor Electronic BetaDIG provides perfect speed stability and easy operation. All parts together result in the sound of a CHALLENGER MK3 so outstanding for his price class. We at Acoustic Signature believe that a motor system for a turntable should have enough energy to speed up the platter but not influence him during rotation. We reach that aim by using a European made Synchronous motor with our own State of the Art motor control.

This engine system is absolute stable in his rotation speed and in combination with the digital control easy to use and reliable. The CHALLENGERMK3 can handle up to 3 Motors and three Tonearms at the same time.
