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 “hard
clipping”. Conse-quently the 7020 can produce remarkably high peak volume levels without sounding
harsh or distorted.
Infrasonic and Ultrasonic Filters
In everyday listen-ing, audio signals often are contaminated with interference at frequencies below and
above the range audible to the ear - turntable rumble, acoustic feedback, and radio inter-ference for
example. The 7020 strips off this interference so that only clean musical waveforms are amplified. Bass
and Treble controls are tailored for musically effective response in the high and low frequencies without
altering the critical mid-range tonal balance. For listening at low volume levels or with sensitive head-
phones, the 7020’s Audio Muting switch expands the useful range of the Volume control and subdues
any residual circuit noise.
Separate “Preamp Out” and “Power Amp In” jacks are provided on the rear panel of the 7020 for
insertion of an equalizer, dynamic range expander or time-delay unit. For the student or first-time stereo
shopper, the “no-frills” design and moderate price make the NAD 7020 an ideal choice; for the music-
lover seeking uncompromised per-formance, few receivers at any price will sound as good in everyday
use.
