NAD 3120


The moderately priced 3120 stereo amplifier provides state of the art performance at effective output power levels substantially greater than would be expected from the conservative rating of 25 Watts per channel.

This remarkable characteristic is made possible by a high voltage, high current output circuit that can deliver short term bursts of double or triple the rated power output in to the typical impedances of real loudspeakers.

NAD's soft clipping circuit permits listening levels beyond even these limits, by reducing harshness at high volume settings.


Power output: 25 watts per channel into 8Ω (stereo)

Frequency response: 20Hz to 20kHz

Total harmonic distortion: 0.02%

Input sensitivity: 0.18mV (MC), 2.7mV (MM), 180mV (line)

Signal to noise ratio: 73dB (MC), 75dB (MM), 104dB (line)

Dimensions: 96 x 420 x 240mm

Weight: 5.26kg

re: 3020/3120 manual missing page

There is a critical page missing from the NAD 3020/3120 service manual, namely, the first four steps of the output stage biasing adjustment. The procedure is almost certainly the same as for other low-power NAD output stages. If anyone has this missing page I would very much appreciate having it to complete the manual. BTW, all other downloads that I have found contain the same omission.

It is nice to have this site.
