304

Stereo Integrated Amplifier

Date of manufacture : Mar 93 - Oct 96

Please note that this document contains the text from the original product brochure, and some technical statements may now be out of date

The 304 essentially extends the 302 with power increased to 35 watts per channel into 8 ohms and
generous headroom permitting untroubled peaks of 120 watts per channel.

NAD’s unique Soft Clipping and Extended Dynamic Power circuits give the 304 the ability to deliver the
maximum impact for dramatic performances without loss of smoothness or clarity. Two sets of heavy
duty binding posts can be used for main plus extra speakers or for bi-wiring, adding to the 304’s
versatility. Its six inputs for audio and video components, provides an amplifier ideal for the most
sophisticated audio and AV systems.
