THE MUSIC HALL MMF-11.1 TURNTABLE, OUR LATEST FLAGSHIP, IS A 2-SPEED BELT-DRIVEN AUDIOPHILE TURNTABLE, FEATURING THE UNIQUE QUADRUPLE-PLINTH CONSTRUCTION ORIGINATED BY MUSIC HALL.
The distinctive design isolates the critical sound reproducing components, each on their own plinth. The tonearm is mounted to the upper plinth and the inverted ceramic main bearing is mounted to the second plinth allowing the partially sunken 1 1/2″ acrylic platter to spin freely.
Moving the main bearing to the second plinth improved cartridge tracking and significantly lowered background noise. The adjustable magnetic-levitation isolation feet, microprocessor speed control, motors, flywheel, and wiring are all mounted to the bottom plinth. The motors, flywheel, and speed control are further isolated on their own vibration damped dual-plinth platform, which is separately isolated from the upper three main plinths.
Sorbothane hemispheres separate each of the three main plinths and provide additional vibration damping. The bottom plinth functions as a mass-loaded resonant sink for the entire turntable. Two motors and a flywheel are used to increase torque and speed stability. The mmf-11.1 comes in a high-gloss piano black lacquer finish and ships without cartridge. A large encapsulating acrylic dustcover is included.
