Acoustic Signature Challenger Mk3 Turntable

The Challenger turntable weighs whole 23kg, to offer you the statement entry level high mass turntable. With this Challenger design, one of the most sophisticated external drive and power supply drive systems is brought together with a massive high mass 50mm thick platter, supported by a solid 40mm thick chassis.

The Challenger is incredibly simple to set up, very versatile and sonically its performance is outstanding, making many other brand turntables costing up to three times the price sound poor in comparison. The Challenger design offers a remarkable and consistent performance at a highly competitive price, and has real visual appeal.

The Design

More ways to amaze. The new Challenger Mk3 is a consequent improvement of the former design. It's all combined with the award-winning performance, elegance, convenience and comfort that have made the mass turntable Series so successful.

Get ready to experience of the Challenger Mk3 Series - now perfectly suited to your own unique style. Perfect surface quality combined with the latest technology and flexibility. Up to 3 motors and 3 tone arms at the same time are possible.

The Drive System

At the new Challenger Mk3 a massive Aluminium plinth of 40mm is combined with a 50mm massive Aluminium platter. This is a perfect fit for the Tidorfolon bearing holding the platter and the exchangeable arm boards.

Arms are placed around the plinth and they are easy adjustable.

A new fully digital motor Electronic Beta DIG provides perfect speed stability and easy operation.

The carefully made Aluminium platter is another part which makes the sound of a Challenger Mk3 so outstanding for its price class.

The Platter

The Challenger Mk3 comes with a precisely manufactured Aluminium platter. It is produced out of a solid piece of soft Aluminium to improve the resonance behaviour. The platter is additionally coated on the back side with a high damping material to get great results.

The thickness of 50mm gives a weight of 10 kilograms. This high weight in combination with the smooth running Tidorfolon bearing is one unique reason of the great music experience the Challenger Mk3 provides.

The Motor

Acoustic Signature believes that a motor system for a turntable should have enough energy to speed up the platter but not influence it during rotation. That aim is reached with the use of a European made Synchronous motor with custom-designed State of the Art motor control.

This engine system is absolute stable in its rotation speed and in combination with the digital control easy to use and reliable. The Challenger Mk3 can handle up to 3 Motors at the same time.

The Bearing

The platter bearing is the heart of every turntable and Acoustic Signature have invented a bearing with the ideal performance characteristics of exact fit, extremely low noise, very low friction and long term stability.

The platter bearing axle is manufactured from special hardened and precisely grinded steel. The bearing housing uses perfectly matched sinter bronze inserts which are self-lubricating. The bearing design was developed to ensure a smooth run and tight fit of the axle.

This is achieved with the use of Sinter bushes and the Tidorfolon bearing ground. Thanks to ultra-tight tolerances, the Tidorfolon bearing lifetime maintenance is free. The bearing  is covered with the 10 year product warranty.
