Technics SL-PS70

 The Technics SL-PS70 with its D/A converter section including MASH 1-bit DAC (multi-stage noise shaping), was able to perform distortion-free reproduction of low-level signals, as well as micro-signals embedded in large signals. The unit used a multi-layer vibration-resistant construction and centre mechanism, which thoroughly eliminated vibration and resonance, as well as four large insulators that reduced vibration from the floor. The line Out circuits included Technics' unique Class AA circuitry.  Also, the power supply circuitry was structured with the audio circuitry specifically independent from the transformer coils. In addition, for comprehensive operation convenience, functionality included CD editing with normal time edit and just time edit selectable, and time fade enabling automatic fadeout.

MASH - Multi-Stage Noise Shaping, is an effective oversampling D/A conversion technique which realizes a high Signal-to-Noise ratio and needs no highly complex manufacturing processes such as a laser trimming. MASH is a trademark of NTT.
