The motor is typically mounted separately or isolated to reduce vibration transfer to the platter.Platter:
Heavy, precisely machined aluminum or composite platter designed to provide high rotational inertia and reduce wow and flutter.
The platter is often fitted with a high-quality mat to further dampen resonance.Chassis and Plinth:
Rigid, multi-layered plinth construction employing vibration-damping materials to minimize resonance and external interference.
The design focuses on mechanical isolation and structural integrity.Tonearm Compatibility:
Designed to accommodate a range of high-performance tonearms, including Alphason’s own models such as the HR-100S and HR-200S.
The tonearm mounting allows precise alignment and adjustment for optimal tracking.Bearing:
Precision bearing assembly with low friction and high stiffness, often using high-quality materials and lubrication to ensure smooth platter rotation and minimal noise.Speed Control:
Electronic speed control with fine adjustment for 33 and 45 rpm, ensuring accurate playback speeds.
Some models may include quartz-locked speed control for enhanced precision.Additional Features:
Heavy-duty feet or isolation platforms to reduce vibration from external sources.
High-quality wiring and connectors to maintain signal integrity.
