The Reference Tonearm series is a prime example
of how the Danish design philosophy and Japanese
precision can produce a truly exceptional product.
Since 1953, Ortofon has been designing tonearms with the goal of
combining craftsmanship and technology, and the Reference Tonearm
series is the culmination of decades of experience and expertise in the
field of audio engineering. It improves upon the great build of our original
legacy AS-212 and AS-309 models, combining exquisite design, precision
manufacturing, and attention to detail, resulting in a beautifully designed
tonearm that delivers outstanding performance.
The classic and beautiful S-shaped tonearm tube is crafted from high-
grade aluminum alloy, offering an optimal combination of rigidity and mass.
The Reference tonearms are intuitive and easy, featuring improved high-
grade bearings, a universal brass connector, and a high-strength alloy that
enhances rigidity. The internal wiring uses Flexible Copper Wire to allow
the arm to move freely without affecting its movement. Its beautiful design
and compatibility with a wide range of cartridges and turntables make it an
attractive option for any vinyl lover.
About the included counterweights
The tonearm comes with two types of counterweights: a standard weight
and a heavy weight, which can be utilized according to the cartridge’s
weight to allow mounting a wide range of cartridges.
For the AS-212R/309R, the standard weight is used for cartridges on
headshell with a total weight of 18 to 26 g, and the heavy weight is for
cartridges on headshell weighing 26 to 38 g.
