Amazon Audio Reference turntable
The chassis of the drive is made from a special ICI material to ensure virtually no resonance. This is a cast material, which has extremely good internal damping features, because of the added extras. They also use 8 LRP elements (Low Resilience Polymer) in their 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 any 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.
The platter is a composite construction, made from aluminum and cast 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.
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.
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 they 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.
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.
