GETTING STARTED

Thank you for purchasing the music hall mmf-7.1 turntable. The music hall mmf-7.1

turntable is 2-speed belt-driven, audiophile quality turntable with many unique features.
It is constructed using a split-plinth design and features an external motor. The mmf-7.1
comes in a high gloss, black piano lacquer finish.

THE SPLIT-PLINTH.
The plinth has three adjustable spiked feet and comes with a set of small discs (cups).
The discs prevent marking of the surface of the supporting shelf. A spirit level is
incorporated on the top platform. The two platforms of the plinth are separated by four
Sorbothane hemispheres, which act as a suspension and isolation system. External
phono sockets are attached to the bottom platform. A high quality interconnect is
supplied.

THE MOTOR
The motor is 12 volt AC and comes with an external power supply. The motor rests in a
cutout on the front, left quadrant of the turntable. It is completely isolated from the table
and sports a blue LED. Placing the motor diagonally opposite the arm reduces any
vibrations caused by the belt from entering into the cartridge. Any vibrations would be
absorbed along the length of the arm thus bypassing the stylus (The stylus moves from
left to right, not front to back).

THE PLATTER
The belt runs round the perimeter of the acrylic platter. Acrylic was chosen for its
superior sound quality and isolation properties. A screw-on record clamp and felt mat
are supplied as standard.

THE ARM
The tonearm is the 'Project Carbon'. This is a carbon fiber version of the acclaimed
Project 9.1 arm. The bearings are made from hardened stainless steel points set in
sturdy ring cages. The counterweight's center of gravity is level with the stylus tip. It is
decoupled from the arm and acts as a resonance damper. The arm also has adjustable
VTA, a damped arm lift and highly flexible internal wiring drawn from high purity copper.

THE CARTRIDGE
The mmf-7.1 comes standard with a Goldring Eroica H, high-output moving-coil
cartridge. The Eroica H was chosen for its low mass, high rigidity body, rare earth
Neodymium magnet, and its Gyger II line contact stylus. It is a perfect complement to
the audiophile qualities of the mmf-7.1. These features combine to ensure that the

mmf-7.1 delivers superior audio performance that will provide years of enjoyment.
