7020 Ster eo Receiver Date of manufacture : ? - Jan 83 Please note that this document contains the text from the original product br ochure, and some technical statements may now be out of date The NAD 7020 receiver is logically designed for optimum performance and ease of operation at an economical price.
Soft Clipping™ When the 7020 is overdriven beyond its rated power , this exclusive NAD circuit gently limits the waveform voltage, ensuring that the output transistors are never driven into saturation or “har d clipping”. Conse-quently the 7020 can produce r emarkably high peak volume levels without sounding harsh or distorted.
