Suspension : The Delphi subchassis / platter / tonearm assembly is suspended by a tripedal mounting,
which custs out room vibrations. Each suspension tower assembly combines 12 different components,
using 7 different mechanical filters, all working as a whole to efficiently control unwanted vibrations.
Bearing assembly : A new system using six precision surfaced nylon screws. With this system Oracle
reaches the highest level of rotational accuracy.
Motor drive electronics and drive belt : Oracle selected a specially designed AC synchronous motor.
The Delphi MK V features a dual current drive circuitry having a maximum start-up torque energy and
minimum efficient operational energy, which guarantees lowest possible motor vibration. The molded
belt plays an important role in maintaining maximum speed stability.
Record / Platter : The maximum rigidity of the 4kg (8.8 pound) platter is immune to vibration by
distributing most of the mass around it’s outer edge. The flywheel effect increases momentum.
Record coupling system : Oracle pioneered the now well established “record clamp system” to solve
specific vinyl disc “warp” problems.
Hard acrylic mat : The Oracle acrylic mat made from specially formulated polymer shows better
matching characteristics (impedance) with the vinyl disc.
Subchassis : Oracle demonstrates that superior engineering can also be aesthetic. The finely brushed
skeletal subchassis will dissipate unwanted energy through efficient coupling and clamping methods.
Maximum rigidity, minimal surface area and energy control are key design.
