Dynavector DV XV-1s Mono cartridge - Manual

Dynavector DRT XV-1s Mono cartridge
Instruction manual
 Despcription
The new Dynavector XV-1s Mono cartridge has been
developed due to enthusiastic requests from mono record
lovers, worldwide. The XV-1s Mono has not been designed
as a typical, old fashioned mono cartridge, but developed
as a true high fi delity component. It is designed to provide
the highest performance and extract the greatest musical
expression possible from mono records. The XV-1s Mono
follows from the innovative design and technology of the
acclaimed XV-1s stereo cartridge and incorporates the
following details and considerations:
 Features
1. Compliance in horizontal and vertical directions
Musical information is recorded in the horizontal direction
on mono records. Tracking the vertical elements will only
lead to extraneous noise or potential damage of the record
groove. Given this, the compliance of the XV-1s Mono
in the vertical direction has been set considerably lower
compared to that of the horizontal direction. A somewhat
"thin" and harsh sound is often experienced when
playing a mono record with a normal stereo cartridge.
A stereo cartridge picks up both the horizontal and the
vertical groove information so that both the music and
unnecessary noise are reproduced.
2. Special coil bobbin design
The corner of the coil bobbin (armature) of the stereo
cartridge is oriented at a 45 degree angle to the record
surface in order to pick up both horizontal and vertical
groove modulations. With the XV-1s Mono, the bobbin
is rotated to be parallel to the record surface. Therefore,
sensitivity to vertical modulation is reduced dramatically
and horizontal modulation is converted directly to the
desired electrical signal. This is the most important feature
of the mono cartridge.
3. Bifi lar wound coil
A typical mono cartridge has two output terminals (hot
and ground) with a single coil. The XV-1s Mono has been
designed with the four output terminals having bifi lar
wound coils. The bi fi lar
wound coil means that dual
separate monaural coils are
connected respectively to
the left and right channel
terminals.
As such, a typical stereo
phono head amplifi er/stereo phono preamplifi er can be
used as is without issues of hum, noise or ground loops.
4. Innovative magnetic circuit design
The magnetic circuit design of the XV-1s Mono follows
directly from the innovative XV-1s stereo cartridge.
Ideal characteristics have been achieved through an
unparalleled magnetic circuit featuring 8 Alnico magnet
rods. The XV-1s Mono also utilizes DV's fl ux damper
(patent) that reduces magnetic distortion. This innovative
circuit provides a presentation that is clear, natural and
musically expressive like no other cartridge before.
5. Stylus tip and cantilever
The cantilever assembly for the XV-1s Mono is of solid
boron with a line contact stylus profi le, similar to that of
the XV-1s stereo cartridge. A line contact stylus profi le is
unusual for a mono cartridge, but the depth of grooves
remain constant on mono records and the shape of the
groove on mono records is at the same average level
found on stereo records. Properly implemented, a modern
line contact stylus can be used with mono records with
great success. As well, the XV-1s Mono cartridge will
not damage a stereo record due to it's moderate vertical
compliance.
