The big brother of the 300 series integrated amplifiers, the NAD 306 carries more worthwhile (we call
them Real World) facilities and features, offers more power and is more flexible and expandable in its
potential than almost any other available. And although the 306 is fully loaded with features, everything
has a sensible purpose which will expand your audio and home cinema system’s potential and increase
your listening pleasure.
Conservatively rated at 50 watts per channel into 8 ohms, the 306 will handle power peaks in excess of
three times that figure, and again thanks to ‘Soft Clipping and ‘EDP’, does so easily, without losing the
drama or presence of the music.
The 306 also offers a sophisticated tone selection configuration, including bass and treble controls, plus
Tone Defeat, a Bass EQ selector that gives a slight boost in the bass response, particularly useful with
smaller loudspeakers. The 306 is especially of interest to vinyl collectors, with our finest discrete, low
noise transistor phono stage offering moving coil and moving magnet cartridge options, Finally, six
stereo programme inputs allow for the full range of video and audio programme sources, including
VCR/Laserdisc plus music via CD, tuner, phono and two tape inputs. The Record Out selector permits
recording from any source whilst listening to another.
In all the NAD 306 is an incredibly versatile amplifier and a glance at the full specifications will prove
that every feature offers a real benefit to your listening pleasure.
