Soft Clipping™
When the 7020i is overdriven beyond its power capacity, the exclusive NAD Soft Clipping™ circuit gently
limits the waveform voltage so that the output transistors are never driven into saturation, i.e. into
“hard clipping”. Thus the receiver can safely be overdriven substantially beyond its rated power on
peaks, yet still continue to sound smooth and musical.
Digital-ready Dynamic Range
The 7020i’s over-load- proof inputs for video, tape and digital Compact Disc can accommodate a
dynamic range greater than 100 dB. Every circuit in the receiver, including its low-impedance tone-
control stage, is designed to minimise background noise and preserve the clarity of your recordings.
Quiet Phono Preamplifier
Unlike many receivers that employ low-cost integrated-circuit (IC) chips for the phono stage, the NAD
7020i employs a refined discrete-transistor phono preamplifier circuit whose signal-to-noise ratio is so
good (75 dB with the phono cartridge connected) that you won’t hear any preamp hiss, even when
playing the quietest recordings.
Musically Useful Tone Controls
Correctly designed tone controls can be a genuinely helpful aid to enjoyable music listening. In the NAD
7020i, the bass and treble controls do what their names imply: they allow you to vary the strength of
the bass and the treble. But at moderate boost/cut settings the important midrange from 300 to 1500
Hz remains essentially flat.
Sensitive Digital Tuning
The 7020i employs precise frequency-synthesis digital tuning; each station is tuned with crystal-
controlled accuracy. A dual-gate MOSFET FM circuit pulls in weak stations well but resists overloading on
strong signals, Multi-stage I.F. filtering provides an optimum combination of sharp selectivity (to separate
closely-spaced stations) and minimum distortion of the stereo signal.
Quiet AM tuning
The AM section is based on an IC that was especially developed for use in digital tuners, It is surprisingly
sensitive, unusually resistant to noise, and provides a more extended high-frequency range than in most
other AM tuning circuits.
