Even the Thales tonearm team cannot turn upside down the laws of physics. But where does it come from that this slim and elegant turntable produces such an overwhelming and nuanced sound experience? The secret lies in the sophisticated art of engineering and craftsmanship of its designers: Besides the elaborate construction and the most precise workmanship the TTT SLIM is carefully tuned to our tangential pivoted tonearm THALES EASY.

Due to many years of experience in the field of analogue tracking we were able to develop such a compact turntable meeting the highest requirements at
the same time. Its delicate and compact design actually ensures the mechanical stability that could never
be achieved by a more extensive concept. Each of
the seventy parts has been carefully designed to
perform its function in the overall concept perfectly.
The turntable is being manufactured in our workshop in Switzerland.

TTT-Slim II: most elegant turntable with battery drive
The most elegant Thales turntable with battery-drive-system (TTT-Slim II) is designed to match the
Thales Easy tonearm perfectly in all aspects: technically, optically and tonally. It provides incredible
accurate and harmonic sound, in a super-compact and sublime design never seen before.
Concept
True to our philosophy, that a turntable with its tonearm
should be one single unit, we have designed a new turntable
for the Thales Easy tonearm. It is manufactured in our workshop piece by piece and meets highest requirements. We are
convinced about the sublime and compact design can provide
mechanical stability which could never be reached by a more
extensive concept. Each of the 70 parts has been carefully designed to perform its function in the overall concept perfectly.
In this documentation we will show you some details of the technical design. But please remember the
final result is not the outcome of sophisticated details only, but the performance of the whole unit as
an ensemble.
Drive
The drive of a turntable is basically very easy: it should make
the record turning with a speed of 33 ⅓ resp. 45 rpm. The list
of what it should not do is much longer: it should not sound
or vibrate at all. It should not be influenced by the mechanical
tracking, no matter in which frequency-range. It should not
care about temperature, humidity or dust. And finally it
should be incredible constant. The human hearing can discern
1Hz difference at its most sensitive frequency (1000 Hz). If we would have to define one hour that
accurate, we should keep a pitch of less than four seconds! For the TTT-Slim II, we have realized a drive
system combining the advantages of the very traditional idle wheel drive (strength and constancy) with
the benefit of the belt drive (silence and decoupling). The motor itself – a brushless DC motor – provides a maximum output of 15 Watts and is mounted on a carefully calculated decoupling element.
This element keeps away all vibration from the chassis, but avoids any axial movement of the motor.
The pulley – which acts as a flywheel to compensate the motor increments – drives the sub-platter via
a precision-belt. The whole drive system is completely covered by the platter.
Bearing
The bearing of the TTT-Slim II is our homage to traditional
craftsmanship. The approved construction is known since
more than 50 years in the industry, while we have brought
the realization and finish to a new level by combining it with
traditional knowledge of our watchmaker. The main shaft is
made of hardened carbon tool steel. Its surface has been
hand polished step by step with basswood and diamondpaste. The shaft runs in a sintered bronze bushing, which has been soaked and heated with specifically
made oil. This guaranties maintenance free running for many decades. Vertically, the shaft ends up in
a spherical shape, lying on a hardened steel ball. The whole bearing is put inside a body made of spheroidal graphite cast iron.
Platter
The platter of the TTT-Slim II has two important tasks: it enlarges the rotating inertial mass and provides the underlay for
the record. The complete mass of the platter is 3.5 kg, but by
concentrating the rotating mass at the outside diameter, the
inertial properties are equal to a massive platter of 5 kg. The
platter is tuned to one single resonance frequency and efficiently damped by a customized high density inlay. This inlay
is at the same time the mat the record is lying on. After choosing the material of the mat by listening tests, we have proved its function by measuring the vibration
of the bare platter compared to the damped one. As you can see in the picture above, the – quite high
– resonance frequency of the platter (upper curve) is completely damped away with the mat (lower
curve). But in all this, the main signal is kept very precise; there is no flattening or blearing, usually
known as «overdamping».
Spikes
The spikes look quite common from outside, but the secret of
the decoupling and leveling mechanism is inside. The spikes
make the turntable standing on balls, keeping it in position by
a small rubber element. This keeps horizontal vibration of the
ground away efficiently. The leveling mechanism is a combination of a machined thread with a high precision sliding fit.
This makes leveling of the unit easy, secure and precise, while
preventing any play or unstable standing. Depending on the base and environment, we do recommend
our air-suspension base Levi-Base.
Electronics
The electronics has been developed especially for our turntable. It is a closed loop controller which keeps the speed of the
motor constant. The feedback of the brushless DC-motor is
compared with an extreme precise reference voltage, which
makes the drive unit significant more accurate than a pll-system with quartz controlled oscillator. The outstanding feature
of the TTT-Slim II is the battery based power supply with Li-Ion
accumulators. The peak capacity is higher than 100 W while using not one single vibrating element.
Therefore it is possible to integrate the power-supply into the main chassis, keep the signal-path short
and skip any connection to the power plant. The battery service life is 20 hours, switching between
playing- and charging-mode is to be operated manually.
