INDEX

Dynavector DV-505 tone arm has an

entirely new concept in tone arm design.

The DV-505 is a high performance tone

arm with various new functions that

make the cartridge in use work the best

way it can. The DV-505 user is requested

to please read through this brochure to

enjoy its niceties fully.

1. Foreword

As is commonly known, a pickup cartridge generates electricity by cantilever motion relative to motion

of cartridge proper. While cantilever stylus precisely traces signals recorded in groove of disk, cartridge

proper receives those signals faithfully provided that it is held motionless (free of vibration). Hence, the

great role of a tone arm.

How should cartridge be held motionless without adverse effects on signal trackability? The DV-505

has solved this problem by adopting the unique (vertical/horizontal) Bi-axis system. The horizontally

movable main arm is of sufficient weight for vibration-free operation, and the adverse effect of weight

on signal trackability is nullified by use of an angular-radial compound bearing design. Conversely, the

vertically movable sub-arm is made so light that it never lets the stylus jump the groove of even a disk

with warp(s) previously unnegotiable.

Also, the DV-505 employs a double damper method -- inertia controlled dynamic damping type plus

electro-magnetic damping type -- to introduce an ideal solution to the problem of tone arm resonance in

low frequency range. This has generally been neglected about audio equipment that absolutely

requires a flat frequency characteristic.
