High-Mass platter and highly rigid stainless-steel spindle
LUXMAN engineers were determined to optimize the final guarantor of stable speed; the platter assembly itself. PD-151 MARK II has a 4.0kg platter precision machined from a thick aluminum billet then diamond-cut finished to exact surfaces. The platter acts as a flywheel, with a large moment of inertia (0.219t·cm2 ) to insure smooth and stable rotation. The spindle supporting the platter is a highly rigid, 16mm diameter, hard stainless-steel shaft with bearings at the lower end. It comfortably supports the platter weight with a bearing structure that combines a thrust bearing lubricated with PEEK* material, with excellent heat and wear resistance, and a brass radial bearing filled with organic molybdenum oil that maintains excellent lubricity under high load. A turntable mat of special vibration-absorbing rubber material is included to support vinyl records during playback.
LUXMAN exterior design pursuing functional beauty
PD-151 MARK II inherits the highly praised LUXMAN exterior design and operational layout of our previous model PD-151. The top panel, made from 10mm thick aluminum with its delicate hairline finish, pursues simplicity and functional beauty with a component layout narrowed down to only the three major analog player elements; the tone arm, drive motor and platter. The operational controls, such as power switch, motor (rotation) ON/OFF switch, rotation speed changeover switch, indicators, etc. are all integrated into PD-151 MARK II front panel. While achieving both highly intuitive operability and visibility, the exquisite aluminum top panel combines with the matte black lower housing to create profound visual contrast. Sold separately is an available and highly recommended, purpose built 4mm thick acrylic dust cover, equipped with cam/spring supporting hinges for easy opening and smooth closure.
LUXMAN 3-step rotation speed switching with independent adjustment functions
The PD-151 MARK II supports three rotation speeds: 33 1/3, 45 and 78 rpm. With the whole system prepared independently for each rotation speed, it is possible to make fine and accurate adjustments while observing the rotation speed deviation indicator (LED)*.
Internal damping material
In order to accurately detect and reproduce an extremely low-level analog audio signal and deliver the output to an amplifier without deterioration, it is necessary to thoroughly suppress unwanted vibrations. Inside the PD-151 MARK II the drive motor and power transformer, which are often sources of such vibrations, are mounted with special damping rubber to prevent interference with high quality audio signals.
