1. Introduction

Thank you for your purchase of the DV-507MKII tonearm.

DV507MKII is a high-performance tonearm with many advanced features, which en-

able it to transmit signals on the record precisely through a cartridge. The original

mass-separation or 'bi-axis inertia' arm was the 505. The 507 MKII is the latest de-

velopment of that revolutionary design with greatly enhanced performance and ease

of use thanks to a major redesign.

Correct installation, set-up and operation are important to provide the best sonic per-

formance.

Please read this instruction manual carefully before attempting installation and use.

2. What is the bi-Axis inertia controlled tonearm.

The tonearm is required to fulll two functions so that the cartridge can reproduce

the exact signal from the record groove. One of these is to hold the cartridge station-

ary at audible frequencies so that the stylus and cantilever motion is translated into

a music system without losses. The other is to allow the cartridge to track warped re-

cords. These require totally contradictory properties from the tonearm and so all con-

ventional tonearms are a compromise between the two. However, a very reasonable

solution exists in the bi-axis tonearm.

The bi-Axis inertia control tonearm is in effect two arms in one - the main arm beam

has an effective-mass that is 3 or 4 times higher compared with conventional tone-

arm but moves only horizontally. On the other hand, the sub-arm has a lower effec-

tive-mass than any conventional tonearm but moves only in the vertical direction.

This combination means that the high effective-mass in the horizontal direction holds

the cartridge steady at audio frequencies, especially at low frequencies and high

groove excursions, whilst the low vertical effective-mass allows unmatched warp rid-

ing performance.

The DV507MKII has unique, non-contact, electro-magnetic damping system that re-

quires no maintenance or adjustment unlike the usual oil damping system. With the

new MK11 this damping is further enhanced by the use of neodymium magnets.
