Belt Driven w/ Precision AC Motor: The NAD C 558’s motor is isolated from noise and voltage fluctuations that occur in the unfiltered AC mains that can cause instability in the motor. The motor uses a specially developed rubber belt that is flat ground for precision and drives a non-resonant sub platter that is precisely machined for smooth rotation and sits in a brass bearing with a hardened steel shaft. The belt can be moved to either the 33 or 45 rpm wheel of the drive pulley to attain the correct speed.
9″ Tonearm w/ Ortofon OM10 Phono (MM) Cartridge: The NAD C 558 turntable is pre-fitted with an Ortofon OM10 phono (MM) cartridge in a 9″ tonearm that offers vertical tracking angle and azimuth adjustment. At 9″ long it offers low tracking distortion while maintaining rigidity and low mass required to stabilize the cartridge. By allowing VTF and Azimuth adjustment you get precise tracking with low distortion and record wear.
Non-Resonant Construction: The NAD C 558’s features a non-resonant sub platter and 10mm glass platter with a felt pad. The turntable’s plinth is solid MDF, not particle board or plastic, and is CNC machined for precision. The removable dust cover is made from a non-resonant Perspex with a counter-sprung hinge design that allows the cover to remain in almost any intermediate position from open to closed. Integrated rubber feet isolate any unwanted external vibration.
Isolated AC Power Supply with Universal Voltage: The NAD C 558 employs a sophisticated power supply that transforms the AC alternating voltage of your wall socket into a pure DC voltage. The DC voltage is then regenerated into a precise AC voltage that powers a precision clock motor to achieve nearly perfect speed consistency and smoothness.
Stereo RCA Outputs: The NAD C 558 is outfitted with stereo RCA output jacks and ground terminal. A 47″ stereo RCA cable with ground lead is included. Make sure the turntable is connected to the Phono (MM) input of your receiver or integrated amplifier. If your receiver or integrated amp is not equipped with a Phono (MM) input, you will need to purchase an external phono-preamplifier (such as the NAD’s phono-preamps, sold separately).
