The TD 126
Mk III by Thorens is "the"
transcription turntable for discriminating music lovers and professional users.
It is the product of 95 years experience in the construction of musical
instruments allied to the mastering of the most advanced technilogy in the
fields of fine mechanics and electronics. The main objectives of Thorens
engineers remain unchanged robustness, reliability and life-time maintenance of
the original performance specification.
In their
constant battle against rumble, Thorens designed a servo controlled electronic
belt-drive to associate with unique floating suspension system.
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 then fulfill the
additional requirement of decoupling motor vibrations almost completely from
the turntable and the pick-up system.
The
turntable platter and the tonearm are both mounted on a secondary chassis
carrying the motor. Thanks to their exclusive design Thorens Transcription
turntables claim rumble figures equalled by no other drive system.
THORENS
ISOTRACK TP 16 Mark III tone arm
For optimum
in tracking ability it is not sufficient that a tone arm has low bearing
friction. It is much more important that is has a low effective mass, because
high mass prevents the stylus from following the imperfections (waro or ripple)
of the record as it should do. To overcome high effective mass one can increase
the stylus force, but this results in excessive record wear. Thorens has solved
the effective mass problem by removing any unnecessary weight from the tone
arm.
The head
shell is reduced to a shielding device, and the detachable connector is placed
close to the pivots where it has negligible influence on the effective mass. In
addition, Thorens Isotrack is a straight arm and not S-shaped. The necessary
offset angle is independent of the arm shape.
Typical arms
have effective masses of around 15 grammes.
The Thorens
Isotrack is half this figure, allowing it to track at the lowest possible
stylus pressures.
A special
surface treatment of the tone arm tube - "split wave technology" -
absorbs all undesirable resonances of tone arm.
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 tonearm motional speed increases towards the
center of the platter. An electronic circuit picjs up the signal produced by
the change in the tonearm velocity and commands the motor to stop and the
tonearm to raise. The precision associated with Thorens turntables is further
emphasised here, since the activation of the auto stop process is not
position sensitive, but fully electronic
and friction-free.
The Thorens
automatic stop system also enables 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 tonearm is
moved by hand over the disc surface. A separate motor is using for tonearm lift
operation.
