NAD’s product philosophy can be characterised in one phrase: “high-value engineering.” The compact

and economical 7225PE receiver is an outstanding example of that approach; it contains much of the

same circuitry as the 7240PE, with less output power and a substantial saving in cost

In budget-level stereo receivers, performance and power often are compromised to reduce production

cost. But NAD combines high production efficiency with superior performance by using the same circuits

in both separates and receivers. The 7225PE contains the entire 3225PE integrated amplifier plus a

sensitive, wide-range digital tuner.

The 7225PE is conservatively rated at 25 watts/ channel of steady-state power for sine-wave test tones

But with +4 dB of IHF dynamic headroom, its effective power for musical transients is considerably

greater. Power Envelope design produces bursts of up to 60 watts/channel at 8 ohms and 8 0

watts/channel at 4 or 2 ohms, ensuring clear and authoritative reproduction of the impact and sparkle

of live music. If you ever overdrive the 7225PE, Soft Clipping™ will prevent the harshness and gritty

distortion that is caused by hard clipping in conventional amplifiers.

NAD’s impedance selector allows optimum performance to be delivered into any speaker impedance

The 7225PE produces up to 15 amperes of peak current, delivering full power to impedances as low as

2 ohms. The quiet phono stage and wide-range line-level circuits, like those in the 7240PE, transparently

reproduce even the subtlest detail of every recorded sound. Infrasonic and ultrasonic filters eliminate

unwanted interference while preserving accurate response from 20 Hz to 20 kHz. Musically effective

tone controls adjust the deep bass and high treble without sacrificing clarity or midrange accuracy

Radio is not just for background music, and tuner performance should not be compromised. The

7225PE employs much of the same highly-evolved technology as the NAD 4225 tuner. A sensitive

MOSFET front end, three stages of I. F. filtering, and a PLL multiplex decoder for wide stereo separation,

provide an optimum combination of good selectivity and low distortion. In side-by-side comparisons

with other receivers, the 7225PE often pulls in weak or difficult stations with noticeably better clarity

and quieting.

NAD 7020 e Stereo Receiver The 7020e, NAD’s lowest cost receiver, is similar to the 7225PE in features

and performance, except that it is based on the 3020i integrated amplifier. It is rated at 20 watts per

channel of steady-state power with +3 dB of IHF dynamic headroom, meaning that in musical transients

it produces up to 40 watts/channel of dynamic power at 8 or 4 ohms

The 7020e shares with all NAD amplifiers and receivers a high-current output stage that, when playing

music instead of test tones, delivers full power to speakers of any impedance. Its combination of

dynamic power, Soft Clipping™, and unconstricted output current give the 7020e a characteristic ability

to drive even “difficult” speakers to unexpectedly high volume levels.

In addition to its surprisingly potent speaker-driving ability, the 7020e contains the same quiet phono

circuitry, sensitive digital tuning, wide stereo separation, sharp audio-bandpass filtering, and musically

useful tone controls that larger NAD receivers employ. The 7020e is a no-compromise product,

characterised by the high-value engineering that stands behind every NAD product.
