AMAZON Audio model turntables share some basic engineering ideas described in the following sessions. The chassis of the drive is made from a special ICI material to ensure virtually no resonance. This has very good internal damping features, partly because it is casted. AMAZON also use 6 LRP elements (Low Resilience Polymer) in its sub-chassis-construction. The LRP elements are arranged in the chassis corners and around the platter bearing. It is pretty easy to set any of the AMAZON Audio turntables. You only have to pay attention to the horizontal adjustment.

As seen above, AMAZON MODEL ONE has a platter that weighs about 5kg and is made from casted metacrylat. It actually is very similar to the vinyl. During a very complex, temperature optimized process the platter gets drilled to its exact dimensions and afterwards follows the quenching and tempering of the surface. This process prevents stress in the material, which would affect the acoustic qualities. Resonance diffuser in the inner area of the platter eliminates the well-known material resonances in massive plastics platter in the area between 9 kHz and 13 kHz.

The rotation-center of the platter is a ceramic ball in the middle of the inversed bearing. Both the bearing bush and vertical axis are made from multiple hardened steel. Accurate selection of components guarantee a perfect, noiseless operation and years enjoying your AMAZON Audio and music. All moving parts are supplied with a very thin but very good greasing special oil from a oil reservoir at the bearing base. Due to the massive body and the special geometry of the bearing, AMAZON Audio platter bearing doesn’t tend to oscillate like many other turntables. That is proven by objective measurements AMAZON Audio has made using a pulse measuring process. Pulses at different areas on the platter are dying out consistent and without excessiveness. An important advantage of inverted bearings is their high fulcrum, which minimizes tilting and moving.

The drive unit is totally separated from the running gear. A very thin string 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 maintains its constant speed with smoothness.

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 smooth operation of the motor is guaranteed. All AMAZON motor units have an 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.
