FINEST ANALOG DEVICES
Chassis:
The chassis of the drive is made from a special ICI material to ensure
virtually no resonance. This is casted material, which has extremely
good internal damping features, because of the added extras. We also use
8 LRP elements (Low Resilience Polymer) in our sub-chassis-construction,
which decouples the plant level from the base on the one hand, and
fights oscillation in the material on the other hand. The LRP elements
are arranged in the chassis corners and around the platter bearing. When
you compare these to metal spring constructions, there are no longer
obnoxious material resonances of the spring or phenomenon’s of sway. The
setting up is uncomplicated and quick, because you only have to care
about the horizontal adjustment; no additional adjustment necessary,
like for example spring elements etc. |

Platter:
The platter is a composite construction, made from aluminum and
casted acryl, enriched with filler. The weight is 12kg and because of
damping purposes there are grooves on the downside in not harmonic
distances. These grooves are filled with vibration blocking material. To
decrease reflections of oscillation which occur during sampling, the
center is made from Teflon and hollow in the middle.
The bearing bush , which is made from steel, is attached as part of the
massive turntable..

Bearing:
The rotation-center of the platter is a ceramic ball in the middle
of the inverse bearing. Both, bearing bush and vertical axis are made
from multiple hardened steel. In numerous production steps, the contact
areas get a intensive polish, which requires a couple of days. Accurate
selection and very little tolerance guarantee a perfect, noiseless
operation and long lifetime. All moving parts are supplied with a very
thin but very good special oil from a oil reservoir at the bearing base.
Due to the massive body and the special geometry of the bearing, our
platter bearing doesn’t tend to oscillate like most of the other. That
is proven by objective measurements we made with the pulse measuring
process. Pulses at different areas on the platter are dying out
consistent and with high edge steepness. |

Motor-Unit:
The drive unit is totally separated from the running gear. A very
thin string made from polyamide carries the power from the pulley to the
platter. You can switch electronically between 33 rpm and 45 rpm. A LSC-Controller
(Linear Speed Controller) monitors all the time the speed and keeps it
absolute constant. These from AMAZON developed controller are only used
in Amazon turntables. In addition, you can fine-tune each speed
separately. Therefore we use padder with a gearbox 1:25.
The heart of the drive is a DC-motor, which is usually used in nautical
navigation devices. This motor is stored isolated and swimming in a
massive box. The result is a absolute constant speed with perfect
running smoothness.

Power supply:
The integrated rechargeable battery power supply is unique for analogue
drives. In play mode, the rechargeable batteries as well as the motor
are totally separated from the mains supply. Thereby, all the disturbing
influences from the mains supply are kept away and a absolutely smooth
running motor is guaranteed. All AMAZON motor units have a intelligent
circuit, which monitors all parameters of the NiMH-batteries while
charging and discharging. The system recharges the batteries
automatically, when it is not in use. One charging cycle is enough to
listen to 180 LP’s.
