The TD 320
is the logical conclusion of the realisation of the experience that Thorens
have made with the development of the world ackowledged "Reference"
and "Prestige" turntables, combined with more than 100 years of
tradition in the reproduction of music. The Thorens TD 320, a concept with
future.

The Thorens
belt-drive
The Thorens
motor drives the turntable platter by means of a rubber belt. The natural
elasticity of the belt prevents most motor vibrations from reaching the platter
and therefore, the pick-up stylus, in more than 20 years of continouous
development, Thorens has reduced the very few disadvantages of belt drive to an
absolute minimum and has brought it to level of technical perfection which is
not approached by any other system known today.
A particular
development is the Thorens acceleration clutch, which prevents the belt from
stretching, thus reducing the starting time and eliminating chassis vibration.
Because of
the high performance required by descerning listeners, Thorens has decided to
retain its own unique belt drive system as long as no better drive system is
developed in Thorens laboratories or elsewhere.
The Thorens
floating suspension
Every
turntable must be damped by a suspension system to prevent the sensitive
pick-up from environmental vibration and from acoustic feedback. If the springs
are placed between motor and turntable platter, they than fulfill the
additional requirement of decoupling motor vibrations almost completely from
the turntable and the pick-up system.
Chassis 1 carries the motor and controls. Chassis 2
which is isolated by three easily adjustable leaf springs carries the platter
and tone arm. The chassis of the 320 is made of amedite material which absorbs
resonances resulting in cleaner and more precise sound.
Specifications
mean very little to how good a turntable sounds.
The
selection of the appropriate materials, the individual tuning, and the
harmonisation of all the components are decisive in determining the sound
quality.
Thorens have
been involved in the production of turntables since the existance of records.
Friction-free
velocity-sensing electronic shut-off
As the
lead-out grooves of records show a higher pitch - i.e. the grooves are further
apart from one another - the tone arm motional speed increases towards the
center of the platter. An electronic circuit picks up the signal produced by
the change in the tone arm velocity and commands the motor to stop and the tone
arm to raise.
The
precision associated with Thorens turntables is further emphasised her, since
the activation of the auto stop process is not position sensitive, but fully
electronic and friction-free.
The Thorens
automatic stopsystem also enables the operator to cue with studio precision at
any point on a disc, even at the operator to cue with studio precision at any
point on a disc, even at the very centre.
Another
circuit prevents the activation of the auto stop process when the tone arm is
moved by hand over the disc surface.
