302 Stereo Integrated Amplifier
Date of manufacture : Apr 93 - Dec 96
Please note that this document contains the text from the original product brochure, and some technical statements may now be out of date
Because our engineers put sound quality first, the budget NAD 302 was voted European Amplifier of
the Year 1993194 and also a Hi Fi Choice ‘Best Buy’. The 302 is modestly rated at 25 watts per channel
into 8 ohms, but effortlessly handles peaks of 75 watts.
Tone Defeat allows you to switch out the tone control circuitry for a more direct signal path. Important
fine detailing like the low noise phono pre-amp, seperate px and power amplifier sections (for future
upgrading) and heavy duty loudspeaker binding posts all add up to make a fine sounding, easy to use
and hugely successful amplifier.
